Warnings, Precautions and Notes
WARNING:
Do not use the following 3-Lead ECG cables with Passport 5L
(P/N, 0998-00-0126-xx) and 5L-CE (P/N, 0998-00-0131xx): 0012-00-0620-05, -06, -07, -08; 0012-00-0722-05, 06, -07, -08; 0012-00-0723-05, -06, -07, -08; 0012-000724-05, -06, -07, -08. The above 3-Lead cables contain a
jumper wire which connects RL (right leg) to LL (left leg). As a
result, when you view aVR, aVL and aVF you will see the
appropriate ECG waveforms (even though you are using a
3-lead cable). However, there may be excessive noise on
these waveforms which can corrupt the heart rate
calculation. See Section 5 in the Operating Instructions for a
list of the proper ECG cables.
WARNING:
When equipped with Nellcor® SpO2, use only Nellcor®
oxygen transducers including Nellcor® OXISENSOR™
patient dedicated adhesive sensors. Use of other oxygen
transducers may cause improper oximeter performance.
WARNING:
Tissue damage or inaccurate measurements may be caused
by incorrect sensor application or use, such as wrapping it
too tightly, applying supplemental tape, failing to inspect
the sensor site periodically, or failing to position it
appropriately. Carefully read the sensor directions for use,
the Passport operating instructions, and all precautionary
information before use.
WARNING:
Excessive ambient light may cause inaccurate
measurements. Cover the sensor site with opaque material.
WARNING:
Inaccurate measurements may be caused by incorrect
sensor application or use; significant levels of dysfunctional
hemoglobins, (e.g., carboxyhemoglobin or methemoglobin);
or intra-vascular dyes such as indocyanine green methylene
blue; exposure to excessive illumination, such as surgical
lamps (especially ones with a xenon light source), bilirubin
lamps, fluorescent lights, infrared heating lamps, or direct
sunlight; excessive patient movement; venous pulsations;
electro-surgical interference; and placement of a sensor on
an extremity that has a blood pressure cuff, arterial
catheter, or intra-vascular line.
WARNING:
In certain situations in which perfusion and signal strength
are low, such as in patients with thick or pigmented skin,
inaccurately low SpO2 readings will result. Verification of
oxygenation should be made, especially in preterm infants
and patients with chronic lung disease, before instituting
any therapy or intervention.
WARNING:
Insure that the conductive parts of ECG electrodes do not
contact other conductive parts including earth ground.
WARNING:
Many patients suffer from poor peripheral perfusion due to
hypothermia, hypovolemia, severe vasoconstriction,
reduced cardiac output, etc. These symptoms may cause a
loss in vital sign readings.

Warnings, Precautions and Notes
WARNING:
The site should be checked at least every eight (8) hours
(every four (4) hours with the Adult re-usable finger sensor).
Ensure proper adhesion, skin integrity, and proper
alignment. Nail polish and fungus may effect readings.
Exercise extreme caution with poorly perfused patients.
Skin erosion and pressure necrosis can be caused when
sensors are not frequently monitored. Assess the site every
two (2) hours with poorly perfused patients.
WARNING:
Do not use the following 3-Lead ECG cables with Passport
XG (P/N’s 0998-00-0133-xx, 0998-00-0134-xx and 099800-0137-xx): 0012-00-0620-05, -06, -07, -08; 0012-000722-05, -06, -07, 08; 0012-00-0723-05, -06, -07, -08;
0012-00-0724-05, -06, -07, -08. The above 3-Lead cables
contain a jumper wire which connects RL (right leg) to LL (left
leg). As a result, when you view aVR, aVL and aVF you will
see the appropriate ECG waveforms (even though you are
using a 3-lead cable). However, there may be excessive
noise on these waveforms which can corrupt the heart rate
calculation. See Section 5 in the Datascope P/N’s 0070-00397, 0070-00-0440, 0070-00-0503 of the Passport
Operating Instructions for a list of the proper ECG cables.
WARNING:
If the sensor or patient cable is damaged in any way,
discontinue use immediately. To prevent damage do not
soak or immerse the sensor in any liquid solution. Do not
attempt to sterilize.
WARNING:
The maximum sampling rate at the nasal cannula is 200 ml/
min. This device should not be used on patients whose
breathing could be impaired by this vacuum flow rate.
WARNING:
Connection of the Passport’s exhaust port to the hospital’s
waste gas scavenge system is recommended to prevent
exposure of hospital personnel to the patient’s respiratory
sample.
WARNING:
In an intubated configuration, ensure all tubing connections
are tight. If tubing disconnects on the monitor side of the
airway adapter, ventilator pressures cause inaccurate CO2
waveforms and readouts to be displayed.
WARNING:
The maximum sampling rate at the nasal cannula is 200 ml/
min. This device should not be used on patients whose
breathing could be impaired by this vacuum flow rate.
WARNING:
Connection of the Gas Module exhaust port (50) to the
hospital’s waste gas scavenge system is strongly
recommended to prevent exposure of hospital personnel to
the patient’s respiratory sample. Vacuum (negative
pressure) should not exceed 1 mmHg at the Gas Module
Pump Exhaust fitting (50). Excessive scavenge vacuum may
result in damage to the Gas Module’s internal pump.

FIGURE 1-1 Front Panel Controls
Introduction
The keys on the front panel of the Passport Monitor are classified as single action, repeat
action, or delayed action keys.
A single action key provides one action each time it is pressed, regardless of how long it is
held.
A repeat action key provides the an action when pressed, then waits half a second before
repeating the action until the key is released.
A delayed action key provides an action, but only after the key has been held pressed for
a (key specific) period of time.
NOTE:
Only one key function will be recognized at any time. The
Passport will ignore multiple key selections.
All key actions are acknowledged by a key click, except for BEEP VOL and ALARM VOL. If a
key is not available a double key click will sound.
1. p and q (UP and DOWN) (Set-Up)
Two repeat action keys used to move the highlighted screen cursor or change the setting/
value of a menu item. As the cursor is moved, the highlighted menu window is displayed.
2. SELECT (Set-Up)
A repeat action key used to select the function or value indicated by the highlighted cursor.

3. END (Set-Up)
A single action key which causes the display to return to the main screen display (as
specified in the DISPLAY section). This key is always available.
4. CENTRAL SILENCE (Optional)
A single-action key which mutes the alarms of the corresponding channel on the VISA Central
Station. The amount of time the alarms are silenced, is determined by the VISA.
5. LEAD (ECG)
A single action key which selects the ECG lead to be displayed. Each depression of the key
selects and displays the next ECG lead from the list. The list wraps around after the last entry
is selected. Choices are: I, II, III, aVR, aVL, aVF or V.
6. SIZE (ECG)
A single action key which selects the ECG size to be displayed. Each depression of the key
selects and displays the next ECG size from the list. The list wraps around after the last entry
is selected.
7. FREEZE (Screen)
A single action key which enables or releases the screen freeze function. The freeze key
stops or starts the ECG waveform (waveform 1), except when waveform 2 is used for
cascaded ECG. When this is the case, pressing the freeze key the first time causes the
currently displayed ECG waveform data to be transferred to waveform 2 and frozen.
Waveforms 1 and 3 continue to move. Pressing FREEZE again causes waveform 2 to return
to cascaded ECG.
8. ZERO 1 (IBP) (Optional)
A delayed action key which zeros the current pressure in the BP1 channel. If the transducer
zero process is unsuccessful, “UNABLE TO ZERO” is displayed in the window containing BP
value. This key is only available when a pressure transducer is present.
9. ZERO 2 (IBP) (Optional)
A delayed action key which zeros the current pressure in the BP2 channel. If the transducer
zero process is unsuccessful, “UNABLE TO ZERO” is displayed in a temporary window
within the parameter window. This key is only available when a pressure transducer is
present.
10. START (NIBP)
A single action key which initiates an NIBP measurement. This function is not available if a
measurement is in progress.
11. INTERVAL (NIBP)
A repeat action key which selects the interval setting for NIBP measurements. Values wrap
around at the lowest/highest choices. Choices are: Off, Continuous, 1, 2.5, 5, 10, 15, 20,
30, 60, and 120 minutes. Five seconds after the selection is made and the key is released,
the new interval takes effect.

12. DEFLATE (NIBP)
A single action key which stops any NIBP measurement in progress, including any timed
measurement sequence, and deflates the cuff. When a timed measurement is stopped an
“NIBP: DEFLATE” message followed by an “NIBP: IDLE” message displays in the NIBP
message window until the timer mode is restarted by either pressing START or changing the
interval.
13. VOLUME (Alarms and Alarm LED)
A repeat action key which adjusts the alarm volume in 5 steps. There is no off position for this
tone. The tone wraps to the minimum volume once the maximum is reached. The red alarm
bell LED illuminates when an alarm condition exists. Refer to “Alarms” on page 1-49.
14. CHECK/RETURN (Alarms)
A single action key which provides access to the alarm menu to view and select alarm
values. Press SELECT to change the alarm values. Pressing CHECK/RETURN a second time
or the END key, returns the display to the main screen and exits the alarm menu.
15. MUTE (Alarms)
A single action and delayed action key which silences all currently alarming parameters or
suspends all alarms. A single key press will silence the current alarm tone for 2 minutes. Any
new alarms that occur while the alarm tone is muted will disable the mute and sound the
Alarm Mute
Symbol
alarm tone. An alarm mute symbol is displayed next to each muted parameter. The word
Mute is displayed above the menu selections.
When the key is pressed and held for 3 seconds, all set alarms will be suspended for 2
minutes. This is indicated by the Alarm Mute Symbol and the words All Mute displayed
above the menu selections.
When “Aud alm standby” is set to ON (in the User Configuration Menu), and the MUTE key
is pressed and held for 4 seconds, all alarms are indefinitely suspended. This is indicated by
the Alarm Mute Symbol in all parameter windows and the words Aud Alm Sby flashing
above the menu selections.
The All Mute and Aud Alm Sby modes can be exited by pressing the mute key.
NOTE:
When “Aud alm standby” is set to ON and the unit is power
off and then on again, the unit will power up in the Aud alm
standby mode.
16. TRENDS/RETURN (Trends)
A single action and delayed action key which displays and clears trended data. The most
recent page of data is displayed when the key is first pressed. Press this key a second time to
view additional trended data. Pressing and holding the key for 3 seconds clears all trended

Operation (5-Lead, 5L, LT and XG)
• ECG SIZE - The ECG size displays a vertical bar and a “1 mV” label. The vertical bar is
used as a reference to determine the size of the displayed ECG waveform. There are a
total of 6 size settings for the vertical bar. Five size settings are 0.25, 0.5, 1, 2, 3 cm.
The sixth setting is larger than the ECG waveform window and therefore the “1 mV” label
is removed. The size that measures a 1 cm signal on the display is indicated by small line
segments added to the top and bottom of the vertical bar (as shown above).
• ECG LEAD - The ECG lead display shows the current ECG lead selection. The lead
display options are I, II, III, aVR, aVF, aVL, and V.
• ECG WAVEFORM - The display shows the ECG waveform at a user selected speed.
This provides 4 seconds of data on the display (at 25mm/sec). The scale of the waveform
is determined by the ECG size selected.
• LEAD FAULT MESSAGE - The lead fault message box displays “ECG Lead Fault” and is
positioned over the area where the ECG waveform normally resides.
• PACER ENHANCEMENT - Factory default is “Pacer enh OFF” (pacer enhancement off).
The OFF setting allows any pacer to appear as it normally would on the ECG waveform.
When pacer enhancement is turned on via patient menu selection, detected pacers are
enhanced and appear as full scale, narrow square waves.
• ESU INTERFERENCE MESSAGE- When a large high frequency noise component is
present on the ECG waveform, the message “ESU Interference” is displayed. If both high
frequency and 60 Hz noise are present, the “ESU Interference” message has priority over
the “Interference” message to display. The “Artifact” message is also displayed in the
Heart Rate window.
• INTERFERENCE MESSAGE- When a large 60 Hz noise component is present on the
ECG waveform and the notch filter is enable, the “Interference” massage is displayed.
Check the patient electrode connectors and the cable for proper connection. The
message may be the result of using inappropriate 3-Lead cables. The “Artifact” message
is also displayed in the Heart Rate window.

When using the thigh cuff, this product will not comply with AAMI accuracy standards.
The limb circumferences of the Color Coded Cuffs adhere to the AHA guidelines for size.
A cuff that is too narrow for the limb will result in erroneously high readings. The correct size
of the pressure cuff for a given patient has, among other considerations, a direct bearing on
the accuracy of the obtained NIBP measurements. Base your selection of the cuff size on the
limb circumference of the patient. Table 1-4 on page 1-25 indicates the available Datascope
cuffs for use with the Datascope Passport Monitor. The design dimensions of the cuffs and
their intended uses are based on recommendations of the American Heart Association.
NOTE:
See Optional Accessories in the Operating Instructions, for a
detailed list of cuffs.
NOTE:
Cuffs become more supple as they age and sometimes
develop permanent folds that can leave temporary marks
on the limb. Any cuffs that exhibit this effect should be
replaced.
NOTE:
Ensure that the pressure tubes are not compressed or
restricted.

The pressure on the limb may not fall to zero between measurements if the cuff is wrapped
too tightly. Therefore, assure that the cuff is properly applied.
The skin is sometimes fragile (i.e., on pediatrics, geriatrics, etc.). In these cases, a longer
timer interval should be considered to decrease the number of cuff inflations over a period of
time. In extreme cases, a thin layer of soft roll or webril cotton padding may be applied to
the limb in order to cushion the skin when the cuff is inflated. This measure may affect NIBP
performance and should be used with caution.
2. Attach cuff hose to NIBP Connector (24).
3. Apply the cuff to the patient. To reduce errors, the cuff should be fitted snugly, with little
or no air present within the cuff. Be sure the cuff lies directly against the patient’s skin.
No clothing should come between the patient and the cuff.
NOTE:
The NIBP cuff should not be placed on a limb that is being
utilized for any other medical procedure. For example, an
I.V. catheter or an SpO2 sensor.
4. Select Patient Size through the PATIENT MENU as described in “Menus” on page 1-64.
Choices are ADULT, PEDIATRIC or NEONATE.
5. If necessary, enter the NIBP parameter menu to change the initial cuff inflation pressure.
Initial cuff inflation pressures depend on the PATIENT SIZE setting. The choices of cuff
inflation are:
TABLE 1-5 Cuff Inflations
PATIENT SIZE SETTING
INITIAL CUFF INFLATION VALUES
Adult
100 - 260 mmHg
Pediatric
60 - 180 mmHg
Neonate
40 - 120 mmHg
6. Press START (9) to begin an NIBP measurement.
NOTE:
Inflate the cuff only after proper application to the patient’s
limb. Cuff damage can result if the cuff is left unwrapped
and then inflated.
The cuff begins to inflate to the selected cuff pressure. After reaching the selected value the
cuff begins to slowly deflate and the Datascope Passport Monitor collects oscillometric
pulsations.
If the initial cuff inflation is found to be inadequate, the unit retries with a higher inflation
pressure (+50 mmHg in the adult mode; +30 mmHg in the pediatric and neonate modes).
Have the patient remain still to avoid the introduction of unnecessary motion artifact. After the
cuff pressure drops below the diastolic pressure, the results of the measurement are
displayed.
If NIBP is the only parameter measured with the Passport, a heart rate can be derived from
NIBP. The HR source menu selection must be in the Auto mode (i.e., not selected for ECG, IBP
or SpO2) and no heart rate alarm limits are set. (see “Alarms” on page 1-49).

If NIBP is a selected trend trigger, then NIBP and heart rate values are stored in trend lists.
The NIBP and NIBP heart rate will be automatically removed from the display after 15
minutes have elapsed.
If another heart rate source is selected (ECG, IBP or SpO2)< before the 15 minute display
time has elapsed, the NIBP heart rate will be replaced by the heart rate from the selected
source.
To display heart rate from NIBP:
a. Choose AUTO for HR source.
b. Discontinue monitoring of ECG, SpO2 and IBP.
c. Set high and low heart rate alarms to off.
d. Make a valid NIBP measurement.
During or after an NIBP measurement, one of several advisory messages may be
displayed. Refer to “Status Messages” on page 1-57, for their explanations.
7. If desired, press DEFLATE (12) to interrupt a measurement. The cuff will deflate.

Automatic Initiation of NIBP Measurements
Follow steps 1 - 5 in Section 1.3.5.1 on page 1-25.
6. Press INTERVAL (11) until the desired time displays. The choices are: OFF, continuous,
1, 2.5, 5, 10, 15, 20, 30, 60, and 120 minutes.
7. A measurement will be taken when the selected interval has elapsed. If an immediate
measurement is desired, press START (10).
NOTE:
If the monitor is in the interval mode when it is turned on,
no measurement will be taken until the “START” key is
depressed. Subsequent measurements are referenced to the
time the unit was turned on. See example in Section 1.3.5.5
on page 1-28.
NOTE:
When the NIBP continuous interval is chosen, the Passport
will continually take back to back blood pressure readings.
As a safety precaution, a five minute limit is placed on
continuous measurements. After 5 minutes, the NIBP
interval will automatically switch to measurements taken
every 5 minutes.
Automatic Adjustment in the Timer Mode
In the timer mode, the unit adjusts the inflation pressure according to the previous reading of
the systolic pressure. After the first measurement in the timer mode, the inflation pressure is
the previous systolic +50 mmHg in the Adult Mode and +30 mmHg in the pediatric and
neonate mode.

ECG Acquisition
The patient ECG signal is acquired with a patient cable and skin electrodes. The type of skin
electrode and technique of applying the electrodes are major factors in determining the
quality of the signal obtained. Use high quality, silver-silver chloride electrodes. These are
designed to acquire the ECG with excellent base line stability, recovery from defibrillation,
and minimum artifact from patient movement.
WARNING:
Ensure that the conductive parts of ECG electrodes do not
contact other conductive parts including earth ground.
1. For optimal skin contact, thoroughly prep patient skin for electrode placement by doing
the following.
• Shave hair from electrode sites.
• Cleanse skin thoroughly with alcohol to remove skin oils.
• Dry with a rough towel or gauze to remove dry skin.
• Attach electrodes to lead wire first before placing onto patient.
NOTE:
Using more than one type of electrode on the same patient
should be avoided because of variations in electrical
resistance.

Messages Associated with ECG Leads
“Lead Off”
• The Passport will display the message “Lead Off” to indicate when ECG monitoring is
inoperative.
“ECG Lead Fault”
• When ECG lead I, II or III is being monitored, a lead fault sensed by RA, LA, or LL will
cause the “ECG Lead Fault” message to display.
• When lead aVR, aVL, or aVF is being monitored, a lead fault sensed by RA, LA, LL, or RL
will cause the “ECG Lead Fault” message to display. When the specified 3-Lead cable is
used, the “ECG Lead Fault” message will display because the RL lead is not available.
• When ECG V lead is being monitored, a lead fault sensed on RA, LA, LL, RL or C will
cause the “ECG Lead Fault” message to display. When the specified 3-Lead cable is
used, the “ECG Lead Fault will display because the RL and C is not available.
WARNING:
1 - 30
Do not use the following 3-Lead ECG cables with Passport 5L
(P/N, 0998-00-0126-xx) and 5L-CE (P/N, 0998-00-0131-xx):

-07, -08. The above 3-Lead cables contain a jumper wire
which connects RL (right leg) to LL (left leg). As a result, when
you view aVR, aVL and aVF you will see the appropriate ECG
waveforms (even though you are using a 3-lead cable).
However, there may be excessive noise on these waveforms
which can corrupt the heart rate calculation. See Section 5 in
the Operating Instructions for a list of the proper ECG cables.

1. Plug the pressure transducer into the PRESSURE TRANSDUCER connector (28) or (29) on
the side panel.
2. To establish a monitoring site introduce an arterial pressure catheter into the patient’s
artery in accordance with standard hospital procedures. “Best practice,” as determined
by the medical community, should be observed.
NOTE:
The arterial pressure catheter should not be used on a limb
that is being utilized for any other medical procedure. For
example, an I.V. catheter or an SpO2 sensor.
3. Connect catheter line with flushing device to the pressure transducer.
4. Zero pressure transducer as follows:
Initially, a “TRANSDUCER NOT ZEROED” message is displayed in the parameter
window, indicating the need to zero the transducer.
a. Open transducer vent to atmosphere.
b. Press ZERO (8) or (9) and hold for a minimum of one second.
After one second has elapsed, an audible click will sound, and the automatic zero
process is complete. The pressure display should indicate zeros.
NOTE:
If the transducer offset should exceed 120 mmHg, it will not
be possible to automatically zero the transducer. Pressure
values will be —- and an “UNABLE TO ZERO” message
replaces the “TRANSDUCER NOT ZEROED” message.
5. Close the pressure transducer vent from atmosphere and check that the pressure
waveform is displayed on the screen.
6. Select the desired pressure scale in the IBP Menu. The choices are: 37.5, 75, 150, or

Datascope Pulse Oximetry Sensors
A. Introduction
A wide range of Datascope sensors are available for connection to Datascope Passport
Monitors equipped with Datascope SpO2. The sensors cover both short-term and long-term
monitoring needs on patients ranging from neonates to large adults.
The DATASENSOR is intended for short-term adult monitoring.
The FLEXISENSOR® SD, available in five different sizes, provides both short-term and longterm monitoring for large adults, adult ear, adults, pediatrics, infants, and neonates. The
FLEXISENSOR® SD is used when the DATASENSOR is not convenient or suitable.
The ear sensor is intended for long-term adult monitoring.
A range of disposable bandages are available for use with the FLEXISENSOR® SDs. They
are available in 3 styles, SENSOR GUARD™ (used for large adults, adults and pediatrics),
Coban with SENSOR GUARD™ (used for infants) and LIGHTGUARD™ (used for neonates).
Use of the sensors does not cause any penetration of the skin, nor is there any electrical
contact or transfer of excessive heat to the patient.
The sensor is composed of a light emitting diode (emitter) and a photo diode (detector). The
emitter discharges two colors (wave lengths) of light into the patient’s extremity (finger, toe,
ear). The detector receives that amount of light not absorbed by the blood or tissue
components. The Passport then uses the relative absorption of the two light wavelengths to
compute and display SpO2 and Rate measurements
• electrocautery noise (ESU) noise
• good motion artifact rejection
• tracking of weak peripheral
• pulse levels
• rejection of ambient light
• Can be re-sterilized (ETO sterilization - 3
times)
• patient isolation
• ease of application and removal
• long term patient comfort

Operation (5-Lead, 5L, LT and XG)
The key benefits of the sensors are:
• Electrocautery Noise (ESU) Rejection - The sensor configuration of both the
DATASENSOR and the FLEXISENSOR® SD provide uninterrupted monitoring and
absence of false alarms during the use of ESU (ESU can be set at any power level). This
design prevents electro-surgical noise entering the monitor, via the sensor, and interfering
with unit operation.
• Monitoring Restless Patients - Motion artifact rejection is achieved in several ways.
1. The sensor design used with their recommended bandages assures a snug fit of the
sensor to the patient.
2. Light emitting diodes (LEDs) and detectors gather a strong signal from the patient.
3. Software in the Passport evaluates the shape of each pulse and automatically rejects
noisy and unreliable pulses.
4. When in the presence of motion, the software adjusts the “averaging-period”,
increasing it to a maximum of 15 seconds during motion, and automatically reducing it
during quiet periods to obtain a fast response. This combination reduces the number of
monitoring interruptions and false alarms from patient motion.
• Tracking of Weak Peripheral Pulse Levels - Many patients suffer poor peripheral
perfusion due to hypothermia, hypovolemia, reduced cardiac output, etc. The Passport is
designed to automatically increase its gain to track patients with poor peripheral
perfusion.
• Rejection of Ambient Light - Many monitoring situations involve high levels of
ambient light, i.e., operating room lights, neonatal phototherapy, heat warmers, etc. The
PASSPORT Monitor, sensors, and bandages each contribute to the rejection of ambient
light. The monitor automatically measures and corrects for high levels of ambient light.
The enclosed design of the DATASENSOR prohibits the interference of high levels of
ambient light on adults with sensor operation. And the opaque material used in the
composition of the bandages, which are used with the FLEXISENSOR® SD, helps keep
out ambient light.
• Patient Comfort - The FLEXISENSOR® SD line is designed to work with a disposable
bandage of three styles (SENSOR GUARD™, Coban and LIGHTGUARD™) which
conform comfortably and safely to the particular patient’s anatomy.
B. Sensor Selection and Application
Selection of a specific sensor is based on the patient’s size, physical condition, and expected
monitoring duration. General guidelines for the selection of a sensor are provided in the
Table 1-7 on page 1-38. Instructions for the application of a sensor to a patient are provided
in each sensor package.
C.
Sensor Connection to the Passport Monitor
1. Align the cable connector on the sensor assembly with the SpO2 Patient Connector (25)
on the Passport Monitor.
2. Push the cable connector into the SpO2 Patient Connector (25). Confirm that the cable
connector is securely in place.
NOTE:
1 - 36
To obtain maximum cable use, do not twist the cable
connector when attaching to or disconnecting from the
Passport Monitor.

D. Sensor Inspection
Before use, always inspect sensors, cables, and connectors for damage, i.e., cuts and
abrasions. Do not use the sensor, cable or connector if damaged. Replace with a good
working sensor.
For long sensor life:
• Do not drop on the floor, or give other sharp shocks to the sensor(s).Between use, store
the sensors in the optional FLEXISENSOR® SD Organizer, accessory pouch, or coil the
sensor cable and store on the side of the Passport using the optional cable retainer. For
accessory part number information see Section 5 in the Operations Manual.
• Avoid running any cart, bed, or any piece of equipment over the sensor cable.
• Avoid strong pulls on the sensor cable (10 lbs/4kg).
• Watch for cracks in the DATASENSOR housing.
• Watch for cracks, cuts, rips, fogging, or signs of moisture in the FLEXISENSOR® SD.
E.
Sensor Performance
For the BEST performance of all Datascope sensors:
• DO NOT PLACE any sensor on an extremity with an arterial catheter or blood pressure
cuff in place. Placement of an arterial catheter or blood pressure cuff on an extremity may
obstruct normal blood flow. False pulse rate information may result if the FLEXISENSOR®
SD is placed on that same extremity. Place the sensor on the limb opposite the site of the
arterial catheter or blood pressure cuff.
• Encourage the patient to remain still. Patient motion may affect the sensor’s performance.
If it is not possible for the patient to remain still, replace the sensor bandage on the
FLEXISENSOR® SD to assure good adhesion, or change the site of the DATASENSOR.
• Check the DATASENSOR site every 2 hours and check the FLEXISENSOR® SD site every
8 hours on adults and every 4 hours on neonatal patients for indications of skin
abrasions, sensor displacement, sensor damage, or circulation impairment. Check the
sensor site every 4 hours if the ear clip is used. If necessary, remove and reapply the
sensor. If any of the above mentioned indications occur, immediately remove the sensor
and find an alternate site.
NOTE:
Check the sensor site more frequently on infant and active
patients.

Operation (5-Lead, 5L, LT and XG)
• Incorrect placement can also reduce the acquired sensor signal, and therefore
compromise performance. Select an alternate site (toe) or use a FLEXISENSOR® SD if the
sensor can not be placed on the patient’s finger correctly or if the fingernails interfere
with the acquisition of a reliable signal.
• Use of the DATASENSOR is not recommended for long-term monitoring (4-6 hours). For
monitoring situations exceeding 4-6 hours, either reposition the DATASENSOR every 2-4
hours to a different site (finger/toe) or use a FLEXISENSOR® SD with its appropriate
bandage.
• Do not over-tighten the sensor bandages. Excessive pressure on the monitoring site can
affect SpO2 readings and may reduce readings below true SpO2. Excessive pressure can
also result in pressure necrosis and other skin damage.
• Sensor configuration provides uninterrupted monitoring in the following situations:
Electro-cautery Noise - ESU rejection is designed into the sensors.
Motion Artifact - The monitor’s software adjusts the “averaging period” increasing it
during motion and reducing it during inactivity. This decreases the number of monitoring
interruptions and false alarms.
Weak Peripheral Pulses - The monitor’s gain is automatically increased to track pulses on
patients with decreased peripheral perfusion.
• SpO2 measurements may interfere with Magnetic Resonance Imaging (MRI) procedures.
• SpO2 is calibrated to display functional saturation.

1. Select the appropriate sensor for the patient (Table 3-1 on page 3-4).
2. Plug the sensor directly into the SpO2 connector located on the side panel of the monitor
or if necessary, use a Nellcor® EC-4 or EC-8 sensor extension cable.
*
This feature applicable only if available / installed in your unit.
NOTE:
Do not place the sensor on an extremity with an invasive
catheter or blood pressure cuff in place.
WARNING:
When equipped with Nellcor® SpO2, use only Nellcor®
oxygen transducers including Nellcor® OXISENSOR™
patient dedicated adhesive sensors. Use of other oxygen
transducers may cause improper oximeter performance.
WARNING:
Tissue damage or inaccurate measurements may be caused
by incorrect sensor application or use, such as wrapping it
too tightly, applying supplemental tape, failing to inspect
the sensor site periodically, or failing to position it
appropriately. Carefully read the sensor directions for use,
the Passport operating instructions, and all precautionary
information before use.
WARNING:
Excessive ambient light may cause inaccurate
measurements. Cover the sensor site with opaque material.
WARNING:
Inaccurate measurements may be caused by incorrect
sensor application or use; significant levels of dysfunctional
hemoglobins, (e.g., carboxyhemoglobin or methemoglobin);
or intra-vascular dyes such as indocyanine green methylene
blue; exposure to excessive illumination, such as surgical
lamps (especially ones with a xenon light source), bilirubin
lamps, fluorescent lights, infrared heating lamps, or direct
sunlight; excessive patient movement; venous pulsations;
electro-surgical interference; and placement of a sensor on
an extremity that has a blood pressure cuff, arterial
catheter, or intra-vascular line.
WARNING:
In certain situations in which perfusion and signal strength
are low, such as in patients with thick or pigmented skin,
inaccurately low SpO2 readings will result. Verification of
oxygenation should be made, especially in preterm infants
and patients with chronic lung disease, before instituting
any therapy or intervention.

1.3.9.1
Nellcor® Sensors
Nellcor® provides a family of sensors suitable for a wide variety of clinical settings and
patients. Specific sensors have been developed for neonates, infants, children, and adults.
OXISENSOR™ oxygen transducers are sterile adhesive sensors with optical components
mounted on adhesive tape. OXIBAND® oxygen transducers and the DURAFORM™ oxygen
transducer system are reusable sensors that are applied with disposable adhesive. The
DURASENSOR® DS-100A adult digit oxygen transducer is a reusable sensor with its optical
components mounted in a plastic casing. The Nellcor® RS-10 reflectance oxygen transducer
is an adhesive sensor for application to forehead or temple.
NOTE:
Nellcor®, OXIBAND® and DURASENSOR® are registered
trademarks of Nellcor® Incorporated. OXISENSOR™ and
DURAFORM™ are trademarks of Nellcor Incorporated.
Selecting a Sensor
Sensors are designed for specific sites on patients with designated weight ranges. To select
the appropriate sensor, consider the patient’s weight, level of activity, adequacy of
perfusion, which sensor sites are available, whether sterility is required, and the anticipated
duration of monitoring.
Cleaning and Re-use
Do not immerse any OXISENSOR™, DURASENSOR®, OXIBAND®, or DURAFORM™
oxygen transducer, the Nellcor® RS-10 oxygen transducer, or any Nellcor® adhesive in
water or cleaning solution. Clean DURASENSOR®, OXIBAND®, and DURAFORM™ oxygen
transducers, and the Nellcor® RS-10 oxygen transducer by wiping with a disinfectant such
as 70% alcohol. Do not sterilize by irradiation, steam, or ethylene oxide. Use a new
OXIBAND® adhesive wrap or FORM-A adhesive bandage for each patient. Do not resterilize OXISENSOR™ oxygen transducers.
Performance Considerations
To ensure optimal performance, use an appropriate sensor, apply it as directed, and observe
all warnings and cautions.
If excessive ambient light is present, cover the sensor site with opaque material. Failure to do
so may result in inaccurate measurements. Light sources that can affect performance include
surgical lights, especially those with a xenon light source, bilirubin lamps, fluorescent lights,
infrared heating lamps, and direct sunlight.

Operation (5-Lead, 5L, LT)
If poor perfusion affects instrument performance, and the patient weighs more than 50 kg
(110 lbs.), consider using the OXISENSOR™ R-15 adult nasal oxygen transducer. Because
the R-15 obtains its measurements from the nasal septal anterior ethmoid artery, an artery
supplied by the internal carotid, this sensor may obtain measurements when peripheral
perfusion is relatively poor. For low peripheral perfusion, consider using the Nellcor® RS-10
reflectance oxygen transducer, which is applied to the forehead or temple.
If patient movement presents a problem:
• Verify that the sensor is properly and securely applied.
• Use a new sensor with fresh adhesive backing.
• Move the sensor to a less active site.
• Use a type of sensor that tolerates some patient motion, such as the OXISENSOR™ D-25,
D-20, N-25, or I20 oxygen transducer.

Special Features
Automatic Calibration
The oximetry subsystem incorporates automatic calibration mechanisms. It is automatically
calibrated each time it is turned on, at periodic intervals thereafter, and whenever a new
sensor is connected. Also, the intensity of the sensor’s LEDs is adjusted automatically to
compensate for differences in tissue thickness.
Each sensor is calibrated when manufactured; the effective mean wavelength of the red LED
is determined and encoded into a calibration resistor in the sensor plug. The instrument’s
software reads this calibration resistor to determine the appropriate calibration coefficients
for the measurements obtained by that sensor.

Oximetry Operating Modes
The Passport’s three operating modes for SpO2 enable it to make accurate measurements
despite differing levels of patient activity. In all three modes, the Passport updates its
measurements with every pulse beat. Data from the most recent beat replaces data from the
earliest beat and new averages are determined and displayed. The three modes are: 1
(default setting), 2, and 3.
1. the default operating mode, uses a 5 to 7 second averaging time and is useful in
situations in which the patient is relatively inactive.
2. this mode uses a 2 to 3 second averaging time and therefore is more affected by patient
motion. It is useful for special applications that require a fast response time, such as
sleep studies.
3. this mode uses a 10 to 15 second averaging time and consequently is least affected by
patient motion. In this mode, pulse rate is not displayed and there is no pulse tone.
Pleth Auto Scaling
The Pleth waveform is automatically scaled when using Nellcor® SpO2. There is no
adjustment that can be made to the pleth waveform size.
Changing Operating Modes
To change from 1 to 2 or 3, select SpO2 in the menu and toggle through the choices of 1, 2,
and 3 using the up and down arrow keys. Press SELECT (2) then END (3) to lock the choice
in and return to monitoring mode. See “Use of Menus” on page 23 for details on using
menus.
The operating mode will be displayed in the pleth waveform window.
1.3.10
Respiration Monitoring
The Passport Monitor offers two kinds of respiratory monitoring: thoracic impedance and
CO2 waveform. Either method may be used to ensure that the patient in not apneic, and both
methods offer certain benefits and limitations.
WARNING:
1.3.10.1
Thoracic respiration measurement may interfere with some
pacemakers. Refer to the pacemaker’s manual.
Thoracic Impedance
The Passport Monitor presents a small electrical signal across the RA and LA ECG limb leads.
This signal changes as the patient’s chest wall rises and falls during the breath cycle. The
advantage of the thoracic impedance method is that respiration is obtained non-invasively
and without any extra cost. Disadvantages include loss of signal when “choke blocks” are
utilized, possible cardiac interference, and missed apneic events.
Choke blocks are electrical filters that may be used in electro-cautery environments where
ECG interference can be substantial. These filters remove the electro-cautery noise, but also
block the signal used by the Passport Monitor to measure respiration.

0070-00-0420
Passport 5-Lead, 5L, LT, XG Service Manual
Operation (5-Lead, 5L, LT and XG)
Operation (5-Lead, 5L, LT)
The filling and emptying of the heart chambers can interfere with the thoracic impedance
signal, so called cardiovascular artifact (CVA), such that the respiratory signal matches the
heart rate. The Passport warns the operator when the respiration value equals the heart rate
by displaying the CVA message.
If the patient’s airway is obstructed and the patient attempts to breath, then the chest wall can
move and create a respiratory signal even though no gas flow is occurring to the patient.
1.3.10.2
CO2 Waveform
When used with the mainstream CO2 analyzer the Passport may use the breath waveform to
report the respiration rate by measuring the actual breaths per unit time. The advantage of
the CO2 waveform method is that the signal is a direct result of respiration and can only
occur if the patient is actually breathing. The disadvantage to the CO2 waveform method is
that intubation is required.

NOTE:
See “User Configuration Mode” on page 53 for Barometric
Pressure and CO2 Units selection.
NOTE:
See “CO2 Messages (only units equipped with Capnostat
CO2)” on page 60 for more details on messages.
Adapter Calibration
Adapter calibration compensates for the optical differences between the adult and neonatal
airway adapters.
Adapter calibration needs to be performed each time the type of airway adapter is switched.
For example: if switching from using an adult to a neonatal or neonatal to an adult adapter a
calibration is needed (not if switching from an adult adapter to another adult adapter).
Adapter calibration should also be performed if the message “Check Adapter” displays.
To perform an adapter calibration:
1. Place the sensor and airway adapter away from all sources of CO2 (including the
patient’s and your own exhaled breath, and ventilator exhaust valves).
2. Choose Start Adapter Cal - Yes from the CO2 menu. (See “Use of Menus” on page 23.)
NOTE:
1 - 44
If the monitor detects changing CO2 levels (breaths) during
an adapter calibration, an “Adapter Cal Failure” message
displays. Remove the source of CO2 and repeat the
calibration.

Use of Adult Airway Adapter
The adult airway adapter should be used when monitoring patients with endotracheal tube
diameters greater than 4.0 mm.
1. Verify the windows are clean and dry. Clean or replace the adapter if necessary.
2. Snap the airway adapter into the Capnostat® sensor. Align the line on the bottom of the
airway adapter with the line on the bottom of the Capnostat®. Press the sensor and
airway adapter together until they “click”.
3. If necessary, perform an adapter calibration. See “Adapter Calibration” on page 44.
4. Place the Capnostat® / airway adapter assembly between the elbow and the ventilator
circuit wye.
NOTE:
For optimal results, DO NOT place the airway adapter
between the endotracheal tube and the elbow, as this may
allow patient secretions to block the adapter windows.
Position the airway adapter with it’s windows in a vertical
and NOT a horizontal position. This helps keep patient
secretions from “pooling” on the windows.
To prevent “rain-out” and moisture from draining into the airway adapter, DO NOT place
the airway adapter in a gravity dependent position.

CO2 Sensor Calibration Verification
Calibration can be verified at anytime and should be verified at least once a week.
To verify calibration:
1. Verify the Passport is turned on and the Capnostat® is connected and warmed-up.
2. Place the Capnostat® sensor onto the REF (reference) cell. The reference cell is the one
farthest from the side of the monitor. The sensor cable should face away from the
Passport.
3. The “Sensor on Reference Cal” message is displayed and the reference value is
displayed in the ETCO2 window. The value should be between 36 and 40 Torr.

CO2 Sensor Calibration
The Capnostat® CO2 sensor does NOT need to be calibrated at each monitor power up.
Calibration of a sensor is required the first time a particular sensor is connected to a
particular monitor and when the monitor requests it.
Once a sensor is calibrated, the Passport can be turned off and on, the sensor can be
unplugged and reconnected, without having to recalibrate. However, if a second sensor is
connected in place of the original, the second sensor must be calibrated and if the original
sensor is used again, it too will have to be recalibrated.

Alarm Violations
There are three types of alarm situations. They are Parameter Alarms, a Heart Rate Fault
Alarm, and an Apnea Alarm.
NOTE:
The heart rate alarm tone has a different pitch than other
alarms.
A. Parameter Alarms
An alarm condition exists if the parameter is equal to or is outside the high/low limit range.
When an alarm limit is violated, the following actions occur:
• The alarm LED (12) flashes.
• The alarm tone is sounded (unless it is muted with the MUTE key (14)).
• The recorder prints the currently selected waveform (if Record On Alarm is selected from
the Recorder menu).
NOTE:
On the waveform printouts that are caused by alarm
situations, a bar is printed above the alarming area. On
trend printouts, the value that has caused an alarm is
printed with square brackets around it. If the recorder is
printing a waveform and an alarm situation occurs, the
currently printing waveform will be completed and then the
alarm waveform printout will be printed.
• The violated parameter is displayed in reverse graphics in the parameter window.

Operation (5-Lead, 5L, LT and XG)
B. Heart Rate Fault Alarm
The Heart Rate Fault Alarm occurs if the selected heart rate source is no longer able to detect
a heart rate. This may be due to an ECG lead fault, a problem with an SpO2 sensor, or
various other reasons. This alarm is only active if a low heart rate limit is set. The alarm
operation is the same as for a parameter alarm. The heart rate value will be dashes (“—-”)
and inverted. A further message from a lead fault or SpO2 fault may be present to help
diagnose the problem.
NOTE:
C.
Only the value displayed in the heart rate window is used
to determine heart rate alarm conditions.
Apnea Alarm
The Apnea Alarm is active when the respiration function is enabled. The Apnea Alarm is
violated when a breath is not detected for a longer period of time than the apnea delay
specified in the Alarm Menu. The alarm operation is the same as for a parameter alarm.
D. General Alarms
• ALARMS OFF - If alarms are not set on any one parameter, an alarm bell off symbol will
be displayed next to the numerical data for that parameter.
NOTE:
Both the high and low alarm must be set for a particular
parameter for the bell symbol to go away.
• VOLUME KEY - Increases or decreases the intensity of the alarm.
• MUTE - Silences all currently alarming parameters for 2 minutes. Any new alarms that
occur, while an alarm tone is muted, will disable the mute and sound the alarm. An alarm
mute symbol (a loudspeaker with a cross through it) is displayed next to each muted
alarm. The word MUTE is displayed above the menu selections area during this time. The
alarms may be suspended for 2 minutes by pressing and holding the MUTE key (14) for 3
seconds. Alarms suspended is indicated by displaying the alarm mute symbol in reverse
graphics. The words ALL MUTE are displayed above the menu selections area during this
time. When the Audio Alarm Standby mode has been enabled and the MUTE key (14) is
pressed and held for 4 seconds, all alarms are indefinitely suspended. This is indicated
by a flashing alarm mute symbol in all parameter windows and a flashing “AUDIO
ALARM STANDBY” message is displayed above the menu selections. Press MUTE to
activate alarms.

Introduction
The keys on the front panel of the Passport XG Monitor are classified as single action, repeat
action, or delayed action keys.
A single action key provides one action each time it is pressed, regardless of how long it is
held.
A repeat action key provides an action when pressed, then waits half a second before
repeating the action until the key is released.
A delayed action key provides an action, but only after the key has been held pressed for
a (key specific) period of time.
NOTE:
Only one key function will be recognized at any time. The
Passport XG will ignore multiple key selections.
All key actions are acknowledged by a key click, except for BEEP VOLUME and ALARM
VOLUME. If a key is not available a double key click will sound.
1. p and q (UP and DOWN) (Set-Up)
Two repeat action keys used to move the highlighted screen cursor or change the setting/
value of a menu item. As the cursor is moved, the highlighted menu window is displayed.
2. SELECT (Set-Up)
A repeat action key used to select the function or value indicated by the highlighted cursor.
3. EXIT (Set-Up)
A single action key which causes the display to return to the main screen display (as
specified in the DISPLAY section). This key is always available.

7. LEAD (ECG)
A single action key which selects the ECG lead to be displayed. Each depression of the key
selects and displays the next ECG lead from the list. The list wraps around after the last entry
is selected. Choices are: I, II, III, aVR, aVL, aVF or V.
8. SIZE (ECG)
A single action key which selects the size of the displayed ECG waveform. Each press of the
key selects and displays the next ECG size which wraps around after the last size is selected.
A vertical bar is placed in front of the ECG waveform. This vertical bar is used as a reference
to determine the size of the displayed ECG waveform.
9. FREEZE (Screen)
A single action key which enables or releases the screen freeze function. The freeze key
stops or starts all waveforms, except when waveform 2 is used for cascaded ECG. When this
is the case, pressing the freeze key the first time causes the currently displayed ECG
waveform data to be transferred to waveform 2 and frozen. Waveforms 1 and 3 continue to
move. Pressing FREEZE again causes waveform 2 to return to cascaded ECG. The freeze key
is also used to enter the user configuration menu. See “User Configuration Mode” on
page 1-153 for further details.
10. ZERO 1 (IBP) (Optional)
A delayed action key which zeros the current pressure in the BP1 channel. If the transducer
zero process is unsuccessful, “UNABLE TO ZERO” is displayed in the IBP1 data window. This
window is only available when a pressure transducer is present.
11. ZERO 2 (IBP) (Optional)
A delayed action key which zeros the current pressure in the BP2 channel. If the transducer
zero process is unsuccessful, “UNABLE TO ZERO” is displayed in the IBP2 data window. This
window is only available when a pressure transducer is present.

the new interval takes effect.
15. DEFLATE (NIBP)
A single action key which stops any NIBP measurement in progress, including any timed
measurement sequence, and deflates the cuff. When a timed measurement is stopped an
“NIBP: DEFLATE” message followed by an “NIBP: IDLE” message displays in the NIBP
message window until the timer mode is restarted by either pressing START or changing the
interval.
16. VOLUME (Alarms and Alarm LED)
A repeat action key which adjusts the alarm volume in 5 steps. There is no off position for this
tone. The tone wraps to the minimum volume once the maximum is reached. The red alarm
bell LED illuminates when an alarm condition exists. See “Alarms” on page 1-149 for
detailed information on alarm situations.
17. LIMITS (Alarms)
A single action key which provides access to the alarm menu to view and select alarm
values. Press SELECT to change the alarm values. Press the LIMITS key again to access

ECG Display Area
FIGURE 1-61 ECG Display Area
The ECG Display Area contains the ECG waveform, the ECG size, scale, lead information,
Pacer Enhancement ON/OFF message, and when appropriate a message indicating there is
no ECG waveform available.
• ECG SIZE - The ECG size displays a vertical bar and a “1 mV” label. The vertical bar is
used as a reference to determine the size of the displayed ECG waveform. There are a
total of 6 size settings for the vertical bar. Five size settings are 0.25, 0.5, 1, 2, 3 cm.
The sixth setting is larger than the ECG waveform window and therefore the “1 mV” label
is removed. The size that measures a 1 cm signal on the display is indicated by small line
segments added to the top and bottom of the vertical bar (as shown above).
NOTE:
Changing the ECG SIZE only changes the display scale not
the ECG amplitude.
• ECG LEAD - The ECG lead display shows the current ECG lead selection. The lead
display options are I, II, III, aVR, aVF, aVL, and V.
• ECG WAVEFORM - The display shows the ECG waveform at a user selected speed. This
provides 4 seconds of data on the display (at 25mm/sec). The
vertical scale of the waveform is determined by the ECG size selected.

Operation (5-Lead, 5L, LT and XG)
• LEAD FAULT MESSAGE - The lead fault message box displays “ECG Lead Fault” and is
positioned over the area where the ECG waveform normally resides.
• PACER ENHANCEMENT - Factory default is “Pacer enh OFF” (pacer enhancement off).
The OFF setting allows any pacer to appear as it normally would on the ECG waveform.
When pacer enhancement is turned on via patient menu selection, detected pacers are
enhanced and appear as full scale, narrow square waves.
WARNING:
Thoracic respiration measurement may interfere with some
pacemakers. Refer to the pacemaker’s manual.
• INTERFERENCE MESSAGE- When large 60 Hz noise component is present on the ECG
waveform and the notch filter is enabled, the “Interference” message is displayed. The
“Artifact” message will also be displayed in the Parameter Display area. Check the
patient electrode connectors and the cable for proper connection. This message may be
the result of using inappropriate 3-Lead cables.
• ESU INTERFERENCE MESSAGE- When a large high frequency noise component is
present on the ECG waveform, the message “ESU Interference” is displayed. If both high
frequency and 60 Hz noise are present, the “ESU Interference” message and the Artifact
message are displayed.

Operation (5-Lead, 5L, LT and XG)
Operation (XG)
A cuff that is too narrow for the limb will result in erroneously high readings. The correct size
of the pressure cuff for a given patient has, among other considerations, a direct bearing on
the accuracy of the obtained NIBP measurements. Base your selection of the cuff size on the
limb circumference of the patient. The table above indicates the available Datascope cuffs for
use with the Datascope Passport XG Monitor. The design dimensions of the cuffs and their
intended uses are based on recommendations of the American Heart Association.
NOTE:
See Accessories section in P/N’s 0070-00-00397, 0070-000440, and 0070-00-0503 for a detailed list of cuffs.
NOTE:
Cuffs become more supple as they age and sometimes
develop permanent folds that can leave temporary marks
on the limb. Any cuffs that exhibit this effect should be
replaced.
NOTE:
Ensure that the pressure tubes are not compressed or
restricted.
*
**
When using the thigh cuff, this product will not comply with AAMI accuracy standards.
The limb circumferences of the Color Coded Cuffs adhere to the AHA guidelines for size.
The pressure on the limb may not fall to zero between measurements if the cuff is wrapped
too tightly. Therefore, insure that the cuff is properly applied.
The skin is sometimes fragile (i.e., on pediatrics, geriatrics, etc.). In these cases, a longer
timer interval should be considered to decrease the number of cuff inflations over a period of
time. In extreme cases, a thin layer of soft roll or webril cotton padding may be applied to
the limb in order to cushion the skin when the cuff is inflated. This measure may affect NIBP
performance and should be used with caution.
2. Attach cuff hose to CUFF Connector (27).
3. Apply the cuff to the patient. To reduce errors, the cuff should be fitted snugly, with little
or no air present within the cuff. Be sure the cuff lies directly against the patient’s skin.
No clothing should come between the patient and the cuff.
NOTE:
The NIBP cuff should not be placed on a limb that is being
utilized for any other medical procedure. For example, an
I.V. catheter or an SpO2 sensor.

4. Select Patient Size through the PATIENT MENU as described in “Use of Menus” on
page 1-109. Choices are ADULT, PEDIATRIC or NEONATE.
5. If necessary, enter the NIBP parameter menu to change the initial cuff inflation pressure.
Initial cuff inflation pressures depend on the PATIENT SIZE setting. The choices of cuff
inflation are:
PATIENT SIZE SETTING
INITIAL CUFF INFLATION VALUES
Adult
100 - 260 mmHg
Pediatric
60 - 180 mmHg
Neonate
40 - 120 mmHg
6. Press START (13) to begin an NIBP measurement.
NOTE:
Inflate the cuff only after proper application to the patient’s
limb. Cuff damage can result if the cuff is left unwrapped
and then inflated.
The cuff begins to inflate to the selected cuff pressure. After reaching the selected value the
cuff begins to slowly deflate and the Datascope Passport XG Monitor collects oscillometric
pulsations.
If the initial cuff inflation is found to be inadequate, the unit retries with a higher inflation
pressure (+50 mmHg in the adult mode; +30 mmHg in the pediatric and neonate modes).
Have the patient remain still to avoid the introduction of unnecessary motion artifact. After
the cuff pressure drops below the diastolic pressure, the results of the measurement are
displayed.
If NIBP is the only parameter measured with the Passport XG, a heart rate can be derived
from NIBP. The HR source menu selection must be in the Auto mode (i.e., not selected for
ECG, IBP or SpO2) with no heart rate alarm limits set. (See “Alarms” on page 1-149, for
details).
If NIBP is a selected trend trigger (see “User Configuration Mode” on page 1-153 for details
on user configuration), then NIBP and heart rate values are stored in trend lists. The NIBP and
NIBP heart rate will be automatically removed from the display after 15 minutes have
elapsed.
If another heart rate source is available, the NIBP heart rate will be replaced by the heart
rate from the selected source.
To display heart rate from NIBP:
a. Chose AUTO for HR source.
b. Discontinue monitoring of ECG, SpO2 and IBP.
c. Set high and low heart rate alarms to off.
d. Make a valid NIBP measurement.
During or after an NIBP measurement, one of several advisory messages may be displayed.
Refer to “Status Messages” on page 1-158, for their explanations.

2.5, 5, 10, 15, 20, 30, 60, and 120 minutes.
7. A measurement will be taken when the selected interval has elapsed. If an
immediate measurement is desired, press START (13).
NOTE:
If the monitor is in the interval mode when it is turned on,
no measurement will be taken until the “START” key is
pressed. Subsequent measurements are referenced to the
time the unit was turned on. See example in “Start and
Deflate Functions” on page 1-114.
NOTE:
When the NIBP continuous interval is chosen, the Passport
XG will continually take back to back blood pressure
readings. As a safety precaution, a five minute limit is
placed on continuous measurements. After 5 minutes, the
NIBP interval will automatically switch to measurements
taken every 5 minutes.

ECG Acquisition
The patient ECG signal is acquired with a patient cable and skin electrodes. The type of skin
electrode and technique of applying the electrodes are major factors in determining the
quality of the signal obtained. Use high quality, silver-silver chloride electrodes. These are
designed to acquire the ECG with excellent base line stability, recovery from defibrillation,
and minimum artifact from patient movement.
WARNING:
Insure that the conductive parts of ECG electrodes do not
contact other conductive parts including earth ground.
1. For optimal skin contact, thoroughly prep patient skin for electrode placement by doing
the following.
• Shave hair from electrode sites.
• Cleanse skin thoroughly with alcohol to remove skin oils.
• Dry with a rough towel or gauze to remove dry skin.
• Attach electrodes to lead wire first before placing onto patient.
NOTE:
Using more than one type of electrode on the same patient
should be avoided because of variations in electrical
resistance.

“ECG Lead Fault” Message
• The Passport XG will display the message “ECG Lead Fault” to indicate when ECG
monitoring is inoperative.
• When ECG lead I, II or III is being monitored, a lead fault sensed by RA, LA, or LL will
cause the “ECG Lead Fault” message to display.
• When lead aVR, aVL, or aVF is being monitored, a lead fault sensed by RA, LA, LL, or RL
will cause the “ECG Lead Fault” message to display. When the specified 3-Lead cable is
used, the “ECG Lead Fault” message will display because the RL lead is not available.
• When ECG V lead is being monitored, a lead fault sensed on RA, LA, LL, RL or C will
cause the “ECG Lead Fault” message to display.
• When the specified 3-Lead cable is used, the “ECG Lead Fault will display because the RL
and C is not available.
WARNING:
1.6.6.1
Do not use the following 3-Lead ECG cables with Passport
XG (P/N’s 0998-00-0133-xx, 0998-00-0134-xx and 099800-0137-xx): 0012-00-0620-05, -06, -07, -08; 0012-000722-05, -06, -07, 08; 0012-00-0723-05, -06, -07, -08;
0012-00-0724-05, -06, -07, -08. The above 3-Lead cables
contain a jumper wire which connects RL (right leg) to LL (left
leg). As a result, when you view aVR, aVL and aVF you will
see the appropriate ECG waveforms (even though you are
using a 3-lead cable). However, there may be excessive
noise on these waveforms which can corrupt the heart rate
calculation. See Section 5 in the Datascope P/N’s 0070-00397, 0070-00-0440, 0070-00-0503 of the Passport

2. To establish a monitoring site introduce an arterial pressure catheter into the patient’s
artery in accordance with standard hospital procedures. “Best practice,” as determined
by the medical community, should be observed.
NOTE:
The arterial pressure catheter should not be used on a limb
that is being utilized for any other medical procedure. For
example, an I.V. catheter or an SpO2 sensor.
3. Connect catheter line with flushing device to the pressure transducer.
4. Zero pressure transducer as follows:
Initially, a “TRANSDUCER NOT ZEROED” message is displayed in the parameter
window, indicating the need to zero the transducer.
a. Open transducer vent to atmosphere.
b. Press ZERO (10) or (11) and hold for a minimum of one second.
After one second has elapsed, an audible click will sound, and the automatic zero
process is complete. The pressure display should indicate zeros.
NOTE:
If the transducer offset should exceed 120 mmHg, it will not
be possible to automatically zero the transducer. Pressure
values will be —- and an “UNABLE TO ZERO” message
replaces the “TRANSDUCER NOT ZEROED” message.
5. Close the pressure transducer vent from atmosphere. If an IBP waveform is desired, use
the Set-up menu (see “Use of Menus” on page 1-109), to assign a waveform window to
display IBP. If the Auto Display function is used to display an IBP waveform, ensure that
the Auto Display CO2 is not set to the same waveform as Auto Display IBP. The Auto
Display feature assigns a higher priority to the CO2 function than IBP. Also, IBP1 has a
higher priority than IBP2.
6. Select the desired pressure scale in the IBP Menu. The choices are: 37.5, 75, 150, or
300 mmHg.
7. Flush arterial line at regular intervals per standard hospital procedure.

Datascope Pulse Oximetry Sensors
A. Introduction
A wide range of Datascope sensors are available for connection to the Datascope Passport
XG Monitor equipped with Datascope SpO2. The sensors cover both short-term and longterm monitoring needs on patients ranging from neonates to large adults.
The DATASENSOR is intended for short-term adult monitoring.
The FLEXISENSOR® SD, available in five different sizes, provides both short-term and longterm monitoring for large adults, pediatrics, infants, and neonates. The FLEXISENSOR® SD is
used when the DATASENSOR is not convenient or suitable.
An adult ear sensor is also available. It is intended for long-term adult monitoring.
A range of disposable bandages are available for use with the FLEXISENSOR® SDs. They
are available in 3 styles, SENSOR GUARD™ (used for large adults, adults and pediatrics),
Coban with SENSOR GUARD™ (used for infants) and LIGHTGUARD™ (used for neonates).
Use of the sensors does not cause any penetration of the skin, nor is there any electrical
contact or transfer of excessive heat to the patient.
The sensor is composed of a light emitting diode (emitter) and a photo diode (detector). The
emitter discharges two colors (wave lengths) of light into the patient’s extremity (finger, toe,
ear). The detector receives that amount of light not absorbed by the blood or tissue
components. The Passport then uses the relative absorption of the two light wavelengths to
compute and display SpO2 and Rate measurements.

The key benefits of the sensors are:
• electrocautery noise (ESU) rejection
• Can be re-sterilized (ETO sterilization - 3
times)
• good motion artifact rejection
• patient isolation
• tracking of weak peripheral pulse levels
• ease of application and removal
• rejection of ambient light
• long term patient comfort
• Electrocautery Noise (ESU) Rejection - The sensor configuration of both the
DATASENSOR and the FLEXISENSOR® SD provide uninterrupted monitoring and
absence of false alarms during the use of ESU (ESU can be set at any power level). This
design prevents electro-surgical noise entering the monitor, via the sensor, and interfering
with unit operation.
• Monitoring Restless Patients - Motion artifact rejection is achieved in several ways.
1. The sensor design used with their recommended bandages assures a snug fit of the
sensor to the patient.
2. Light emitting diodes (LEDs) and detectors gather a strong signal from the patient.
3. Software in the Passport evaluates the shape of each pulse and automatically rejects
noisy and unreliable pulses.
4. When in the presence of motion, the software adjusts the “averaging-period”,
increasing it to a maximum of 15 seconds during motion, and automatically reducing
it during quiet periods to obtain a fast response. This combination reduces the
number of monitoring interruptions and false alarms from patient motion.
• Tracking of Weak Peripheral Pulse Levels - Many patients suffer poor peripheral
perfusion due to hypothermia, hypovolemia, reduced cardiac output, etc. The Passport is
designed to automatically increase its gain to track patients with poor peripheral
perfusion.
• Rejection of Ambient Light - Many monitoring situations involve high levels of
ambient light, i.e., operating room lights, neonatal phototherapy, heat warmers, etc. The
Passport Monitor, sensors, and bandages each contribute to the rejection of ambient
light. The monitor automatically measures and corrects for high levels of ambient light.
The enclosed design of the DATASENSOR prohibits the interference of high levels of
ambient light on adults with sensor operation. And the opaque material used in the
composition of the bandages, which are used with the FLEXISENSOR® SD, helps keep
out ambient light.
• Patient Comfort - The FLEXISENSOR® SD line is designed to work with a disposable
bandage of three styles (SENSOR GUARD™, Coban and LIGHTGUARD™) which
conform comfortably and safely to the particular patient’s anatomy.
B. Sensor Selection and Application
Selection of a specific sensor is based on the patient’s size, physical condition, and expected
monitoring duration. General guidelines for the selection of a sensor are provided in the
Sensor Selection Table, page 1-44. Instructions for the application of a sensor to a patient
are provided in each sensor package.
C.
Sensor Connection to the Passport Monitor
1. Align the cable connector on the sensor assembly with the SpO2 Patient Connector (28)
on the Passport XG Monitor.

Operation (5-Lead, 5L, LT and XG)
2. Push the cable connector into the SpO2 Patient Connector (28). Confirm that the cable
connector is securely in place.
NOTE:
To obtain maximum cable use, do not twist the cable
connector when attaching to or disconnecting from the
Passport XG Monitor.
D. Sensor Inspection
Before use, always inspect sensors, cables, and connectors for damage, i.e., cuts and
abrasions. Do not use the sensor, cable or connector if damaged. Replace with a good
working sensor.
For long sensor life:
• Do not drop on the floor, or give other sharp shocks to the sensor(s). Between use, store
the sensors in the optional FLEXISENSOR® SD Organizer, accessory pouch, or coil the
sensor cable and store on the side of the Passport using the optional cable retainer. For
accessory part number information see Section 5 in Datascope P/N’s 0070-00-0397,
0070-00-0440, 0070-00-0503 of the Passport Operating Instructions.
• Avoid running any cart, bed, or any piece of equipment over the sensor cable.
• Avoid strong pulls on the sensor cable.
• Watch for cracks in the DATASENSOR housing.
• Watch for cracks, cuts, rips, fogging, or signs of moisture in the FLEXISENSOR® SD.
E.
Sensor Performance
For the BEST performance of all Datascope sensors:
• DO NOT PLACE any sensor on an extremity with an arterial catheter or blood pressure
cuff in place. Placement of an arterial catheter or blood pressure cuff on an extremity may
obstruct normal blood flow. False pulse rate information may result if the FLEXISENSOR®
SD is placed on that same extremity. Place the sensor on the limb opposite the site of the
arterial catheter or blood pressure cuff.
• Encourage the patient to remain still. Patient motion may affect the sensor’s performance.
If it is not possible for the patient to remain still, replace the sensor bandage on the
FLEXISENSOR® SD to assure good adhesion, or change the site of the DATASENSOR.
• Check the DATASENSOR site every 2 hours and check the FLEXISENSOR® SD site every
8 hours on adults and every 4 hours on neonatal patients for indications of skin
abrasions, sensor displacement, sensor damage, or circulation impairment. Check the
sensor site every 4 hours if the ear clip is used. If necessary, remove and reapply the
sensor. If any of the above mentioned indications occur, immediately remove the sensor
and find an alternate site.
NOTE:
1 - 122
Check the sensor site more frequently on infant and active
patients.

Operation (XG)
• Incorrect placement can also reduce the acquired sensor signal, and therefore
compromise performance. Select an alternate site (toe) or use a FLEXISENSOR® SD if the
sensor can not be placed on the patient’s finger correctly or if the fingernails interfere
with the acquisition of a reliable signal.
• Use of the DATASENSOR is not recommended for long-term monitoring (4-6 hours). For
monitoring situations exceeding 4-6 hours, either reposition the DATASENSOR every 2-4
hours to a different site (finger/toe) or use a FLEXISENSOR® SD with its appropriate
bandage.
• Do not over-tighten the sensor bandages. Excessive pressure on the monitoring site can
affect SpO2 readings and may reduce readings below true SpO2. Excessive pressure can
also result in pressure necrosis and other skin damage.
• Sensor configuration provides uninterrupted monitoring in the following situations:
Electro-cautery Noise - ESU rejection is designed into the sensors.
Motion Artifact - The monitor’s software adjusts the “averaging period” increasing it
during motion and reducing it during inactivity. This decreases the number of monitoring
interruptions and false alarms.
Weak Peripheral Pulses - The monitor’s gain is automatically increased to track pulses on
patients with decreased peripheral perfusion.
• SpO2 measurements may interfere with Magnetic Resonance Imaging (MRI) procedures.
• SpO2 is calibrated to display functional saturation.

WARNING:
Inaccurate measurements may be caused by incorrect
sensor application or use; significant levels of dysfunctional
hemoglobins, (e.g., carboxyhemoglobin or methemoglobin);
or intra-vascular dyes such as indocyanine green methylene
blue; exposure to excessive illumination, such as surgical
lamps (especially ones with a xenon light source), bilirubin
lamps, fluorescent lights, infrared heating lamps, or direct
sunlight; excessive patient movement; venous pulsations;
electro-surgical interference; and placement of a sensor on
an extremity that has a blood pressure cuff, arterial
catheter, or intra-vascular line.
WARNING:
In certain situations in which perfusion and signal strength
are low, such as in patients with thick or pigmented skin,
inaccurately low SpO2 readings will result. Verification of
oxygenation should be made, especially in preterm infants
and patients with chronic lung disease, before instituting
any therapy or intervention.
WARNING:
Many patients suffer from poor peripheral perfusion due to
hypothermia, hypovolemia, severe vasoconstriction,
reduced cardiac output, etc. These symptoms may cause a
loss in vital sign readings.
WARNING:
The site should be checked at least every eight (8) hours
(every four (4) hours with the Adult re-usable finger sensor).
Ensure proper adhesion, skin integrity, and proper
alignment. Nail polish and fungus may effect readings.
Exercise extreme caution with poorly perfused patients.
Skin erosion and pressure necrosis can be caused when
sensors are not frequently monitored. Assess the site every
two (2) hours with poorly perfused patients.
WARNING:
If the sensor or patient cable is damaged in any way,
discontinue use immediately. To prevent damage do not
soak or immerse the sensor in any liquid solution. Do not
attempt to sterilize.

Masimo® Sensors and Patient Cable
Masimo® provides a family of sensors suitable for a wide variety of clinical settings and
patients. Specific sensors have been developed for neonates, infants, children, and adults.
All sensors are indicated for continuous noninvasive monitoring of arterial oxygen saturation
(SpO2) and pulse rate. The LNOP DCSC Adult Reuable Spot Check Sensor is used for ‘‘Spot
Check’’ applications. The LNOP® - DC1 Adult Re-usable Finger Sensor can also be used for
“spot check” applications if needed. All sensors are intended for “single-patient use only”
unless indicated as ‘‘reusable’’.
Selecting a Sensor
Sensors are designed for specific sites on patients with designated weight ranges. To select
the appropriate sensor, consider the patient’s weight, level of activity, adequacy of perfusion,
which sensor sites are available and the anticipated duration of monitoring.
Cleaning And Re-use
The sensor may be reattached to the same patient if the emitter and detector windows are
clear and the adhesive still adheres to the skin. The adhesive can be partially rejuvenated by
wiping with an alcohol wipe and allowing the sensor to thoroughly air dry prior to
replacement on the patient.
Performance Considerations
To insure optimal performance, use an appropriate sensor, apply it as directed, and observe
all warnings and cautions.
If excessive ambient light is present, cover the sensor site with opaque material. Failure to do
so may result in inaccurate measurements. Light sources that can affect performance include
surgical lights, especially those with a xenon light source, bilirubin lamps, fluorescent lights,
infrared heating lamps, and direct sunlight.
In the event that you are unable to get any reading, or the reading you get is inaccurate,
consider the following:
• If your patient is poorly perfused, try applying the sensor to another site - such as a
different finger or toe.
• Check that the sensor is properly aligned.
• In electrosurgery, make sure sensor is not too close to ESU devices or cables.
• Check to make sure the site area is clean/non-greasy, clean site and sensor if needed.
Nail polish and fungus should be removed.
• Excessive patient motion can affect readings and may cause a “SpO2 Interference”
message to be displayed. Encourage the patient to remain still. If this is not possible try
moving the sensor to another site.
If patient movement presents a problem:

• Verify that the sensor is properly and securely applied.
• Use a new sensor with fresh adhesive backing.
• Move the sensor to a less active site.
• Ensure proper sensors are used for the proper application. For instance, LNOP® - Adt

Special Features
Automatic Calibration
The oximetry subsystem incorporates automatic calibration mechanisms. It is automatically
calibrated each time it is turned on, at periodic intervals thereafter, and whenever a new
sensor is connected. Also, the intensity of the sensor’s LEDs is adjusted automatically to
compensate for differences in tissue thickness.
Each sensor is calibrated when manufactured; the effective mean wavelength of the red LED
is determined and encoded into a calibration resistor in the sensor plug. The instrument’s
software reads this calibration resistor to determine the appropriate calibration coefficients
for the measurements obtained by that sensor.
Oximetry Sensitivity Modes and Post Average Time
The Passport has two sensitivity modes for SpO2, normal and high. The user should choose
the sensitivity mode depending upon signal quality and patient motion. In most cases, the
normal setting will be appropriate. If the patient motion is limited, high sensitivity can be
used. High sensitivity will provide a better reading, however detection of a “SpO2 SENSOR
OFF” condition will be less.
The Passport has the ability to change the averaging of the Saturation, Pulse Rate, and Signal
Strength measurements for SpO2. The post average time can be changed to 4,6,8,10,12,14
or 16 seconds.
Pleth Auto Scaling
The Pleth waveform is automatically scaled when using Masimo® SpO2. There is no
adjustment that can be made to the pleth waveform size.
Changing Sensitivity Modes
To change the sensitivity mode, select SpO2 in the menu and toggle the sensitivity mode
choices for normal and high. Press SELECT (2) and EXIT (3) to lock in the choice and return to
monitoring mode. See “Use of Menus” on page 1-109.
Changing Post Average Time
To change the post average time, select SpO2 in the menu and set the post average time
between 4 and 16. Press SELECT (2) and EXIT (3) to lock in the choice and return to
monitoring mode. See “Use of Menus” on page 1-109.

Selecting a Sensor
Sensors are designed for specific sites on patients with designated weight ranges. To select
the appropriate sensor, consider the patient’s weight, level of activity, adequacy of perfusion,
which sensor sites are available, whether sterility is required, and the anticipated duration of
monitoring.
Cleaning and Re-use
Do not immerse any OXISENSOR™, DURASENSOR®, OXIBAND®, or DURAFORM™
oxygen transducer, the Nellcor® RS-10 oxygen transducer, or any Nellcor® adhesive in
water or cleaning solution. Clean DURASENSOR®, OXIBAND®, and DURAFORM™ oxygen
transducers, and the Nellcor® RS-10 oxygen transducer by wiping with a disinfectant such
as 70% alcohol. Do not sterilize by irradiation, steam, or ethylene oxide. Use a new
OXIBAND® adhesive wrap or FORM-A adhesive bandage for each patient. Do not resterilize OXISENSOR™ oxygen transducers.
Performance Considerations
To insure optimal performance, use an appropriate sensor, apply it as directed, and observe
all warnings and cautions.
If excessive ambient light is present, cover the sensor site with opaque material. Failure to do
so may result in inaccurate measurements. Light sources that can affect performance include
surgical lights, especially those with a xenon light source, bilirubin lamps, fluorescent lights,
infrared heating lamps, and direct sunlight.
If poor perfusion affects instrument performance, and the patient weighs more than 50 kg
(110 lbs.), consider using the OXISENSOR™ R-15 adult nasal oxygen transducer. Because
the R-15 obtains its measurements from the nasal septal anterior ethmoid artery, an artery
supplied by the internal carotid, this sensor may obtain measurements when peripheral
perfusion is relatively poor. For low peripheral perfusion, consider using the Nellcor® RS-10
reflectance oxygen transducer, which is applied to the forehead or temple.
If patient movement presents a problem:
• Verify that the sensor is properly and securely applied.
• Use a new sensor with fresh adhesive backing.
• Move the sensor to a less active site.
• Use a type of sensor that tolerates some patient motion, such as the OXISENSOR™ D-25,
D-20, N-25, or I20 oxygen transducer.

Oximetry Operating Modes
The Passport’s three operating modes for SpO2 enable it to make accurate measurements
despite differing levels of patient activity. In all three modes, the Passport updates its
measurements with every pulse beat. Data from the most recent beat replaces data from the
earliest beat and new averages are determined and displayed. The three modes are: 1
(default setting), 2, and 3.
1. The default operating mode, uses a 5 to 7 second averaging time and is useful in
situations in which the patient is relatively inactive.

Respiration Monitoring
The Passport XG Monitor offers two kinds of respiratory monitoring: thoracic impedance and
CO2 waveform. Both methods offer certain benefits and limitations. A respiration source must
be selected, see “Resp Menu” on page 1-179.
WARNING:
1.6.11.1
Thoracic respiration measurement may interfere with some
pacemakers. Refer to the pacemaker’s manual.
Thoracic Impedance
The Passport XG Monitor presents a small electrical signal across the RA and LA ECG limb
leads. This signal changes as the patient’s chest wall rises and falls during the breath cycle.
The advantage of the thoracic impedance method is that respiration is obtained noninvasively and without any extra cost. It is important to use cables with internal resistors for
Thoracic Impedance, see Section 5 in the Datascope P/N’s 0070-00-0397, 0070-00-0440,
0070-00-0503 Passport Operating Instructions for a list of cables.
Choke blocks are electrical filters that may be used in electro-cautery environments where
ECG interference can be substantial. These filters remove the electro-cautery noise, but also
block the signal used by the Passport XG Monitor to measure respiration.
The filling and emptying of the heart chambers can interfere with the thoracic impedance
signal, so called cardiovascular artifact (CVA), such that the respiratory signal matches the
heart rate. The Passport XG warns the operator when the respiration value equals the heart
rate by displaying the CVA message.
If the patient’s airway is obstructed and the patient attempts to breath, then the chest wall can
move and create a respiratory signal even though no gas flow is occurring to the patient.

CO2 Waveform
When used with the optional mainstream/sidestream CO2 or optional Gas Module the
Passport XG may use the breath waveform to report the respiration rate by measuring the
actual breaths per unit time. The advantage of the CO2 waveform method is that the signal is
a direct result of respiration and can only occur if the patient is actually breathing. Refer to
Section 1.6.12 on page 1-134 through Section 1.6.14 on page 1-146 for more details on
the above options for CO2 monitoring.

Adapter Calibration
Adapter calibration compensates for the optical differences between the adult and neonatal
airway adapters for mainstream CO2 operation.
Adapter calibration needs to be performed each time the type of airway adapter is switched.
For example: if switching from using a re-usable adult to a neonatal or neonatal to a reusable adult adapter, a calibration is needed (not if switching from a re-usable adult adapter
to another re-usable adult adapter). Adapter calibration should also be performed if the
message “Check Adapter” displays.
NOTE:
In order to perform an accurate adapter calibration, the
“Sensor Warming Up” message must not be displayed.
To perform an adapter calibration:
1. Place the sensor and airway adapter away from all sources of CO2 (including
the patient’s and your own exhaled breath, and ventilator exhaust valves).
2. Choose Start Adapter Cal - Yes from the CO2 menu. (See “Use of Menus” on page 1109.)
NOTE:
If the monitor detects changing CO2 levels (breaths) during
an adapter calibration, a “Breaths Detected ... Retry”
message displays, and then an “Adapter Cal Failure”
message will display. Remove the source of CO2 and repeat
the calibration.

Sidestream CO2 Gas Monitoring
Sidestream Capnography is a technique used for measuring the CO2 in the respiration of
adult and pediatric patients. Sidestream capnography can be acquired via a nasal cannula
(non-intubated) or through a sampling line connected to a breathing circuit (intubated).
WARNING:
The maximum sampling rate at the nasal cannula is 200 ml/
min. This device should not be used on patients whose
breathing could be impaired by this vacuum flow rate.
WARNING:
Connection of the Passport’s exhaust port to the hospital’s
waste gas scavenge system is recommended to prevent
exposure of hospital personnel to the patient’s respiratory
sample.
The sidestream application has an inherent start-up delay. For situations where time to
waveform is critical the mainstream application is quicker.
The sidestream application has an inherent CO2 measurement delay caused by the time the
sample takes to travel from the monitoring site to the sampling airway adapter. The longer
and/or wider the sampling tube, the longer the delay.
NOTE:
The pump must be turned-off before any change is made to
the tubing configuration, including nasal cannula, nafion
tubing, filter or airway adapter with sample tube. After the
changes are made, start the pump as described in step 6 in
Section Section 1.6.13.1 on page 1-140.
NOTE:
For sidestream operation, always set the apnea and CO2
alarms.

Calibration of a sensor is required the first time a particular sensor is connected to a
particular monitor and when the monitor requests it.
Once a sensor is calibrated, the Passport XG can be turned off and on, the sensor can be
unplugged and reconnected, without having to recalibrate. However, if a second sensor is
connected in place of the original, the second sensor must be calibrated and if the original
sensor is used again, it too will have to be recalibrated.

Gas Module Option
The Gas Module option allows for the measurement of anesthetic gases, O2, N2O and CO2
levels. Measurement can be acquired via a nasal cannula (non-intubated) for oxygen and
CO2 only, or through a sampling line connected to a breathing circuit (intubated).
WARNING:
1.6.14.1
The maximum sampling rate at the nasal cannula is 200 ml/
min. This device should not be used on patients whose
breathing could be impaired by this vacuum flow rate.
Sequence for Monitoring Anesthetic Gases, O2, N2O and/or CO2
1. For non-intubated patients, apply the nasal cannula to the patient. For intubated patients
connect the sample line to the breathing circuit. Refer to instruction provided in the
packets.
2. Connect the other end of the nasal cannula or sample line to the Gas Module at the
Input Port (41). Refer to Figure 1-57 on page 93. Do not connect anything to Reference
Port (51), Figure 1-58 on page 95, on the rear of the unit. This port is used to monitor
the room air only. Ensure all tubing connections are tight.
WARNING:
1 - 146
Connection of the Gas Module exhaust port (50) to the
hospital’s waste gas scavenge system is strongly
recommended to prevent exposure of hospital personnel to
the patient’s respiratory sample. Vacuum (negative
pressure) should not exceed 1 mmHg at the Gas Module
Pump Exhaust fitting (50). Excessive scavenge vacuum may
result in damage to the Gas Module’s internal pump.

6. Observe the capnogram on the monitor’s display. When the Passport XG has detected
valid breaths, numbers will display for CO2, O2, Agent, N2O and Respiratory Rate.
NOTE:
The Gas Module must be warmed up a minimum of two
minutes for accurate CO2, O2 and N2O readings and five
minutes for agent readings.
7. If not already set, use the Setup Menu, to select “Auto Display CO2” waveform to be
displayed on Waveform 2 or Waveform 3.
8. If desired, the Gases waveform scale and speed can be changed by entering the Gases
menu. See “Use of Menus” on page 1-109 for details.
NOTE:
1.6.14.2
See “Gas Module Messages (on Passports with Gas Module
installed only)” on page 1-164 for more details on
messages.
Gas Monitor Calibration
Accuracy verification of the Gas Module is recommended at six (6) month intervals or
whenever gas readings appear to be in error. The date of the last successful mixture
calibration appears at the bottom of the “Gases” menu. The operator may elect to perform a
Zero calibration (lasting approximately 10 seconds) or a Span calibration (lasting
approximately 2 minutes) at any time. During the calibration session gas readings and all
other gas functions are not available.
Zero calibration is a single action command that compensates all gas channels for the effects
of offset drift. Zero calibration may be performed on command and also takes place
automatically at preset intervals. To manually perform a Zero cal, choose ‘YES’ from the Zero
calibration gas menu (refer to “Gas Module Menu” on page 1-182).
Span calibration is a set of prompted commands that enables the operator to align the gas
display(s) to specific gas concentration(s) within the Datascope Calibration Gas canister.
Span calibration can be initiated by the operator any time the gas module’s readings are
suspected to be inaccurate. Span calibration should be performed if after performing a Zero
cal, the gas readings do not display the accurate valves.
Always verify accuracy using a full canister of Datascope approved precision calibration
gas, after calibration is performed. Never use calibration gas that has expired, has a
different concentration, or a canister that is indicating low pressure. The pressure indicator
on the Datascope gas regulator must operate in the green zone during the entire calibration
session.

Alarm Violations
There are three types of alarm situations. They are Parameter Alarms, a Heart Rate Fault
Alarm, and an Apnea Alarm.
NOTE:
The heart rate alarm tone has a different pitch than other
alarms.
A. Parameter Alarms
An alarm condition exists if the parameter is equal to or is outside the high/low limit range.
When an alarm limit is violated, the following actions occur:
• The alarm LED (16) flashes.
• The alarm tone is sounded (unless it is muted with the MUTE key (18)).
• The recorder prints the currently selected waveform (if Record On Alarm is selected from
the Recorder menu).
NOTE:
On the waveform printouts that are caused by alarm
situations, a bar is printed above the alarming area. On
trend printouts, the value that has caused an alarm is
printed with square brackets around it. If the recorder is
printing a waveform and an alarm situation occurs, the
currently printing waveform will be completed and then the
alarm waveform printout will be printed.
• The violated parameter is displayed in reverse graphics in the parameter window.

Operation (5-Lead, 5L, LT and XG)
B. Heart Rate Fault Alarm
The Heart Rate Fault Alarm occurs if the selected heart rate source is no longer able to detect
a heart rate. This may be due to an ECG lead fault, a problem with an SpO2 sensor, or
various other reasons. This alarm is only active if a low heart rate limit is set. The alarm
operation is the same as for a parameter alarm. The heart rate value will be dashes (“—-”)
and inverted. A further message from a lead fault or SpO2 fault may be present to help
diagnose the problem.
NOTE:
C.
Only the value displayed in the heart rate window is used
to determine heart rate alarm conditions.
Apnea Alarm
The Apnea Alarm is active when the respiration function is enabled. The Apnea alarm is
violated when a breath is not detected for a longer period of time than the apnea delay
specified in the Alarm Menu. The alarm operation is the same as for a parameter alarm.
D. General Alarms
• ALARMS OFF - If alarms are not set on any one parameter, an alarm bell off symbol will
be displayed next to the numerical data for that parameter.
NOTE:
Both the high and low alarm must be set for a particular
parameter for the bell symbol to go away.
• VOLUME KEY - Increases or decreases the intensity of the alarm.
• ALARM MUTES - One or more alarms can be muted for either a period of 2 minutes or
indefinitely. The following is a description of how to enable the different mute modes.
Alarm Bell
Off Symbol
SINGLE MUTE - Any current alarm can be muted for 2 minutes by pressing the MUTE
key (18). Any new alarms that occur, while in this mode, will disable the mute and
sound the alarm. An alarm mute symbol (a loudspeaker with a cross through it) is
displayed next to each muted alarm. The word MUTE is displayed above the menu
selections area during this time. This mode will expire after 2 minutes or by pressing the
mute key again.
ALL MUTE - All alarms can be suspended for 2 minutes by pressing and holding the
MUTE key (18) for 3 seconds. Any new alarms that occur, while in the all mute mode,
will not sound the alarm. All alarms suspended is indicated by displaying the alarm
mute symbol in reverse graphics. The words ALL MUTE are displayed above the menu
selections area during this time. This mode will expire after 2 minutes or by pressing the
mute key again.
AUDIO ALARM STANDBY MODE - This feature can only be enabled in the User
Configuration Menu. Refer to the table below for a description of the three choices
“OFF”, “ON”, or “ON and ACTIVE on Power up”. This feature allows alarms to be
suspended indefinitely by pressing and holding the MUTE key for 4 seconds. This is
indicated by a flashing alarm mute symbol in all parameter windows and a flashing
“Aud Alm Sby” message is displayed above the menu selections. When in this mode,
press MUTE to re-activate alarms.

1.6.21
Operation (5-Lead, 5L, LT and XG)
Connection to External Devices (optional)
The Passport XG provides a high level ECG waveform output from the J1 connector (37). To
facilitate connection of the Passport to external devices requiring an ECG waveform for
synchronization, Datascope provides interface cable:
• P/N 0012-00-0753-01 cable which is terminated with a Hewlett Packard (HP) 8 pin
round connector, commonly used for ECG input on HP defibrillators.
This cable attenuates the high level ECG waveform output from the Passport XG Monitor to a
low level output and is intended to provide a means to synchronize compatible external
devices with an ECG signal. An example of such a device is a defibrillator for cardioversion
synchronization.
CAUTION:
1.6.22
It is the users responsibility to confirm correct operation of
the Passport XG with external devices. Before using this
cable it is essential that a biomedical engineer verify correct
operation of the Passport XG with an external device using
this cable. Testing should include verification that the
maximum delay for cardioversion synchronization does not
exceed 60 ms (monitor and defibrillator). Cable should be
labeled with the devices they have been tested for use with.
Using the Passport XG with the Visa Central Station (optional)
The Passport XG must be connected, either through hardwire or telemetry, to the VISA
Central Station. This connection allows the Passport XG to communicate with the VISA to
ADMIT, DISCHARGE, SILENCE and PRINT. The serial output type in the User Configuration
Menu must be set to either “VISA” or “VISA WITH ADMIT”.
NOTE:
The VISA Central Station cannot be used in conjuction with
the Gas Module option.
If set to “VISA”, the passport XG can be used to mute alarms and print waveforms on the
VISA. However, the ADMIT and DISCHARGE features will be disabled.
If set to “VISA WITH ADMIT”, the Passport XG can be used to help ADMIT and DISCHARGE
patients to and from the VISA, as well as mute alarms and print waveforms on the VISA.
NOTE:
See the VISA Operating Instructions, P/N 0070-00-0245, for
more details on VISA operation with the Passport XG.
The keys that are used on the Passport XG in conjunction with the VISA are: ADMIT (4),
DISCHARGE (5), SILENCE (6) and PRINT (22).

Block Diagrams
The Block Diagrams indicate the internal organization of the instrument. It depicts several
circuit boards, numerous connectors and the cathode ray tube. The block diagrams are used
to gain both familiarity with the instrument and locate malfunctioning PC boards as readily as
possible. To avoid clutter, the number of PC board interconnects is minimized. The
interconnects shown represent major or essential signal flow and clock connections. Also, the
power supply connections for each board are shown.

Detail
Refer to the block diagram (Figure 2-5 on page 2-8), and complete circuit schematics, while
reading the following operation description.
The Interconnect Board can be viewed simply as the hardware connection between the
monitors external patient connectors for ECG, respiration, invasive pressure, and
temperature, and the internal signal processing circuitry. As it does this, it also provides high
voltage transient suppression.
ECG
Connection to the patient is made by ECGRA, ECGLA, ECGRL, ECGLL, and ECGC, via P3, a
standard ECG connector. Transient high voltage suppression is provided by R1, R2, R3, R9,
R10, CR1, CR2, CR3, CR10, and CR11. The resistors act as current limiting devices, while
the bidirectional transorbs limit the output signal voltages of RA, LA, RL, LL, and C, to 200
volts differential to “Shield” potential. “Shield” is ultimately connected to isolated ground on
the Front End Module.

After the high voltage suppression stage, each ECG leadwire’s signal enters a separate RC
filter to attenuate electro-surgical frequencies, as well as the respiration carrier generated on
the Front End Module. The five RC filters are R11-C6, R6-C9, R8-C7, R5-C10, and R7-C8.
Respiration
Connection to the patient is made by ECGRA, and ECGLA, via J3. High voltage protection,
up to 6000 volts differentially, is provided by capacitors C1 and C2. The patient signal is
finally routed to the Front End Module as RRA and RLA, via J1.
Pressure
This monitor incorporates two invasive pressure transducer channels. Connection to the
patient for the P1 channel is via connector P1, and for the P2 channel, connector P2. Voltage
excitation for the transducers is provided by the +IN and -IN signals which is a 5v supply (-IN
is connected to isolated ground on the Front End Module). Transducer output is carried
differentially on the +OUT and -OUT (P1 and P2) signals to the Front End Module. High
voltage electrostatic discharge protection is provided by suppressors CR8 through C12.
Temperature
Both Series 400 and Series 700 type sensors can be connected to the monitor using the
connector jack J4. The input signals are protected by transient voltage suppressor CR9. EMI
and RFI suppression is provided by common mode choke L1, and C3, C4, and C5. TIP,
RING, and SLEEVE signals are sent to the Front End Module via J1.
Controlled High Voltage Discharge
The Interconnect board provides a specific path to bleed off slowly accumulated static energy
to non isolated monitor ground, through R4, a 100 MW resistor. Rapid accumulation of
charge (voltage) at levels of over approximately 5500 volts, are discharged through DG1, a
gas spark gap device to non isolated monitor ground potential. The connection to the non
isolated monitor ground is via a direct wire strap from the resistor and spark gap
combination non isolated side, to the monitor’s internal center chassis structure.

Theory of Operation
Frontend Board/Daughter Board
Overview
The Passport Frontend Module consists of nine major blocks: the ECG, pressure, respiration,
temperature, isolated power supply, A/D converter, isolated microcontrollers, non-isolated
microcontroller, and data isolation sub-systems.
The ECG channel has five lead capability. It has an analog gain of 390, incorporates pacer
detect/reject processing, and electrosurgery interference detection function.
The dual invasive pressure channels each provide for a linear input range of -20 to +300
mmHg and can reject up to 120 mmHg of offset. The P1 channel systolic trigger level is fixed
at approximately 18 mmHg.
Patient respiration monitoring is accomplished using standard impedance pneumography,
actively driving a patient through the RA and LA ECG leads with several hundred
microamperes at 114kHz. Respiration can be measured over a range of 50 to 2000 ohms
equivalent body impedance. The circuitry outputs a signal representing a modulation of this
impedance, up to a maximum of 10 ohms.
The temperature preamplifier is capable of measuring with either 400 or 700 series
thermistor sensors. Measurement is valid over the range of 15 to 45 degrees C. Integral
calibration is provided internally at an equivalent temperature of 37.5 degrees C.
The Frontend Module creates its own isolated power from the system’s bulk power source,
which is either an unregulated 11 to 18 volt supply, or a battery supply of 11 to 14 volts. The
power conversion is implemented with a switch mode forward converter, to provide an
isolated supply of approximately 8 volts. Regulated +5 volts for circuitry and pressure
transducers is accomplished using series linear regulators.
Analog to digital conversion is implemented with a 12 bit converter, having 11 multiplexed
analog inputs and a serial digital data output. This function is controlled by an isolated
microcontroller, which also controls the configuration and operation of the various subcircuits. This processor is an 8 bit low power microcontroller with parallel I/O capability.
The isolated microcontroller communicates in a serial format with the non-isolated
microcontroller via opto-couplers, from which it receives its operational information, and to
which it sends the patient data and circuit status.
The non-isolated microcontroller is a high-performance 32 bit integrated processor with
direct memory access.

Daughter Board
The daughter board connects to the front end board at the existing J41 header, and also at a
new connector installed in the location formerly occupied by multiplexer U3. The J41 header
was the original attachment for the interconnect board in the 3-lead version. The respiration,
pressure and temperature signals simply pass through the daughter board from the
interconnect board to their original pins on J41. The ECG signals, however, are intercepted
to provide the 5-lead functions. Certain signals not available on J41, such as power and the
lead selection lines, are obtained from the connector installed in place of U3.
Each of the leadwires RA, LA, LL, RL and C, is brought from the interconnect board through
J2. The active leads (RA, LA, LL and C) are passed through an ESIS filter, consisting of two
cascaded R-C stages. For RA, this consists of R2-C1 and R19-C5, while identical circuits are
provided in the remaining leadwires. Each signal is then buffered by one section of quad
opamp U1, which is connected as a voltage follower. The buffer amplifier is used to provide
a bootstrapped lead bias for lead fault detection. Again using RA as a example, the series
connected diode pair CR1 and resistor R26 produce a level shifted version of the buffered
RA signal. This level shifted signal will always track two diode drops, or about 1.2 volts,
more negative than the RA signal. Bias resistor R1 is connected from this level shifted signal
to the RA lead input. Therefore, regardless of the voltage at the RA input (within range) a bias
current equal to (1.2 volts)/R1, or about 55 nA, flows as the lead bias. This bias current is
negative, meaning that the buffered lead signal will assume a strong negative voltage (near
the negative supply rail) when the leadwire is disconnected. Each of the active leads has an
identical circuit.
The RL lead has a different circuit, because it is used only as a drive lead, and never as an
active (input) lead. When displaying any lead except, I, II or III, a 5-wire cable is needed,
and RL is the drive lead. However, to allow compatibility with 3-wire cables when displaying
leads I, II or III, the LL, LA and RA wires (respectively) are used as the drive. The selection of
the drive lead is performed by multiplexer IC U4. Resistor R32 is used to attenuate the drive
signal (supplied from the front end board) so that it cannot exceed the +5 volt supply rail of
U4. Were this to occur, U4 would malfunction, and lead fault would not be reliably detected.

Block Diagrams
Theory of Operation
The buffered active lead signals are applied to a conventional Wilson network, consisting of
resistors R11, R13, R16, R17, R21, R23, R24, R27 and R29. These resistors provide the
weighted leadwire signals when displaying leads aVR, aVL and aVF, as well as the “Wilson
Central Terminal” (WCT) for display of lead C. For example, lead aVR is defined as 50%
each of the LL and LA signals taken as one ECG amplifier input, and RA as the other.
Resistors R11 and R17 perform the 50% weighting of signals LL and LA. Similarly, the C lead
is defined as the voltage on the C leadwire, measured against the average of the RA, LA and
LL voltages, known as the WCT. Resistors R13, R21 and R27 develop the WCT voltage. The
correct points for each lead display are picked off of the Wilson network by multiplexers U2
and U3. The outputs of these multiplexers are called ECG+ and ECG-, corresponding to the
positive and negative inputs of the ECG amplifier on the front end board. They are carried to
the front end board on pins 4 and 10 of J1, which mates with the connector installed in the
former site of U3 of the front end board. On the front end board, jumpers installed in position
U4 carry these signals to lines F and G, which are the inputs of ECG differential amplifier
U33.
The lead select multiplexers, U2 and U3, as well as the drive multiplexer, U4, are controlled
by three select lines, which select one of 7 leads or the ECG calibrate function. The lines
LSEL0 and LSEL1 correspond to the original LS0 and LS1 lines used in the 3-lead version. An
additional line, LSEL2, has been added to allow selection of the added leads. The network
R14-C11 in this line provides isolation between the microcontroller and the ECG
multiplexers, and is identical to the networks found in the LS0 and LS1 lines on the front end
board.
Lead fault detection is performed by measuring the DC voltage of the ECG+ and ECGsignals. Resistors R33 and R34, together with diodes CR5 and CR6, select the lower (more
negative) of the two voltages on these points, and routes it to signal A, which is passed to the
lead fault comparator on the front end board. The operation of the lead fault detection takes
into account simulators which may short the ECG and pressure circuits together. The Passport
will not show a spurious lead fault with most such simulators, although it may fail to detect
certain lead faults when the pressure is connected to the simulator. Since this is a different
operating mode than the original Passport lead fault detection, the lead fault comparator has
been modified, as is discussed below.
Front End Board
The ECG section of the front end board has been modified from the previous 3-lead system.
The ESIS filters and lead bias resistors have been removed entirely. U3 has been replaced by
a connector which mates with the daughter board. Multiplexer U4 has been replaced by two
jumper wires, which allow the ECG signal from the daughter board to pass to the ECG
amplifier U33, as has been discussed previously. The additional lead selection line has been
added by connecting pin 27 of U38 to pin 1 of the connector used in place of U3. This line
is activated when enhanced microcontroller and Datasette software is used. In order to allow
the software to be backwards compatible with the 3-lead system, the 5-lead board is
identified by grounding pin 21 of the microcontroller, which is high on the 3-lead systems.

Theory of Operation
Block Diagrams
The drive amplifier signal is attenuated, as discussed above, by R32 on the daughter board,
and R12 on the front end board. To restore the drive gain to a higher value, R160 has been
increased to 30.1 K. To facilitate the new lead fault detection scheme, the bias point of the
drive amplifier has been changed slightly be changing R161 and R162. The lead fault
sensing voltage arrives from the daughter board by pin 5 of the connector installed in place
of U3. The signal is buffered by voltage follower U34, and then processed by the lead fault
comparator, U24. Lead fault is indicated when this signal becomes too negative. Therefore,
the comparator, which was originally configured as a window comparator, has been
modified to detect only negative voltages. When a simulator having a connection between
the ECG and pressure is used, the lead fault voltage is driven in a positive direction, and will
therefore not indicate lead fault. The modification of the comparator consists of omitting
diode D30 and resistor R166. A noise filter has been constructed by installing a 22.1 k
resistor in place of D37, and a 0.1 uF capacitor in place of R165. The threshold voltage of
the comparator has been adjusted by changing R168 and R214. When the leads are
attached, the voltage applied to the comparator is roughly -0.4 volts. When lead fault
occurs, this voltage becomes more negative, passing the approximately -1.3 volt threshold
set by R168 and R214.
Because the lead fault is detected from the output of the lead select multiplexer, only those
leadwires actually involved in producing the displayed lead are monitored for lead fault.
Therefore, only RA, LA and LL are considered in lead I, II or III; additionally RL is considered
in aVR, aVL and aVF; and all leadwires are considered in C. However, because the aVR,
aVL, aVF and C lead selections involve averaging the voltage on two or three electrodes, the
lead fault indication is less strong on these lead selections. This is because the bias voltage of
the disconnected lead may become averaged with the voltage of a lead which is still
attached. Therefore, the lead fault comparator will see a voltage nearly equal to the negative
supply rail if a fault occurs in leads I, II or III, but will see a voltage as little as -2 volts if one
of LA, RA or LL is detached in lead C.

Respiration
In Fig. 2-8, the connection to the patient is made through two leads marked RRA and RLA,
which ultimately become RA and LA on the body. A 114 KHz, 500 microamp RMS sinewave
is applied to the patient through the electrodes (which are positioned more to either side of
the chest than usual while doing a 3 lead ECG). The signal is applied to the electrodes
through a small isolation Transformer (T2) and the respiration signal is reflected back through
this same transformer. The purpose of the isolation is not for patient safety (that barrier is
elsewhere) but to eliminate other stray return paths for the signal and thus an error in the
signal.

Generation of the patient drive starts at U18, which chops between a 5 volt reference and
ground to produce a 114 kHz square wave of a precision amplitude with respect to the
analog to digital converter (i.e., the same 5 volt reference is used for the A/D reference).
The respiration drive can be disabled by a logic high on the RESPEN* signal, which inhibits
U18. A second order Bandpass Filter, U11 and associated parts, transforms this square
wave into an approximation of a sinewave, approximately 4 volts peak to peak, centered on
0 volts. This sinewave drives the inverting input of U11, the Patient Drive Amplifier, through
R91. Thus, the current in Transformer T2’s primary (being in the feedback loop of U11) is
constrained to be the sinewave voltage divided by the value of R75, resulting in
approximately 500 microamperes. The secondary signal, which is the same as the primary,
because the transformer has a 1:1 winding ratio, is applied to the electrodes via resistors
and capacitors on the Interconnect board. The capacitors behave as a short to the 114 kHz
sinewave carrier, but as a very high (greater than 5 megohms at 10 Hz) shunting impedance
to the ECG electrodes so as not to attenuate the ECG signal.

Block Diagrams
Theory of Operation
The patient’s resistance variation due to respiration (.05 ohm to 5 ohms, out of 50 ohms to
2K W unmodulated impedance) reflects back through the transformer and results in a
voltage variation at Patient Drive Amplifier U11 pin 7 of approximately 69 microvolts to 6.9
millivolts. This modulated voltage sits on a carrier of approximately 3 to 8 volts. The above
modulation and carrier values assume zero cable capacitance shunting the patient
impedance. For typical cable capacitances (325 pf for 10’ patient cable) and reasonable
patient impedances of less than 1 kilohm, this attenuation is not appreciable, nor is any noise
created by moving the patient leads. Even for the smallest of modulated signals (about 70
microvolts), the carrier amplitude at the output of U11 is sufficient (about 3 volts p-p, centered
around 0 volts) to forward bias rectifier CR35. After halfwave rectification, the signal
amplitude is roughly 700 microvolts per ohm. The carrier portion of the signal ranges from
approx. +0.9 to +3.4 volts (which is half the voltage less a .6 volt diode drop). Differenced
with +2.5 volts and amplified by DC Amplifier U13, this yields a carrier range of -2.2 to
+4.2 volts at U13 pin 1. Increased cable capacitance would serve to make these values
more negative. With as much as a 500 pf cable capacitance (325pf +/-25% is more
realistic), the largest patient impedance of 2000 ohms will receive the greatest attenuation
resulting in a carrier at U13 pin 1 of -1.5 volts. At the other extreme, a patient impedance of
200 ohms, the same cable yields approximately -2.2 volts.
The signal from U13 pin 1 is AC coupled at approximately 0.1 Hz by C5 and R176, then
amplified with a gain of 580 by AC Amplifier U44 for a net gain of 1 volt per ohm (at zero
cable capacitance). This amplifier rolls off at about 4 Hz. Combined with the high frequency
cutoff of the demodulator and the AC Amplifier, this results in an overall low pass corner
frequency cutoff of about 3Hz.
Comparator U13 compares the voltage at U13 pin 1 with a 2.3 volt reference in order to
generate a “ Hi Impedance ” or “lead off” indicator signal, causing a Capacitor Reset to be
initiated by an analog switch in U18 and R103. This speeds up the signal’s return to within
the active range of the opamps. After being clipped to 5 volt level by CR41, the indicator
signal is delayed by resistor R184 and C11 just long enough for C5 to sample and capture
the proper voltage following restoration of an open lead. The lead off threshold is set just
beyond the maximum patient impedance, or approximately 2200 ohms at the leads
(assuming zero cable capacitance; greater with shunting capacitance).
The impedances of capacitors on the Interconnect Board connected to the RRA and RLA
wires, along with the clamping of CR32, CR38, and shield in T2, protect U11 from
defibrillator discharges.

The Pressure Preamplifier (Figure 2-9 on page 2-17) is comprised of two channels of
identical Differential Amplifiers. The P1 channel amp is comprised of U20 and associated
components. The amp has a gain of 195 at DC, a bandwidth of approximately 15 Hz (the 3 dB point), an output biased of 1.8 volts. This biasing is necessary to allow for transducers
that have positive or negative offsets as large as 120 millimeters of mercury (mmHg). Full
scale output is limited to 300 mmHg positive pressure, relative to atmosphere, and is scaled
at 4.88 millivolts (one A/D lsb) per mmHg, assuming a transducer scale factor of 5

Theory of Operation
The P1 channel output is used for generating a systolic trigger, for heart rate measurement
purposes. The P1 pressure signal is fed through a Bandpass Filter, comprised of U21 and
associated components, to remove the mean pressure level and noise, and to set the
appropriate amplitude detection scaling. The signal is then measured by the Pulse Detect
comparator, U21, which has a minimum threshold of 189 mmHg, set by the hysteresis
created by R133 and R148. Its output, P-Trigger, is a variable duty cycle square wave whose
rise and fall is coincident with the systolic and diastolic portions of the pressure waveform.
This systolic trigger “logic” is detected by the microcontroller and communicated to the
Control Module.
Temperature
The temperature channel is designed to measure temperatures from 15°C to 45°C using
Yellow Springs series 400 or series 700 thermistor probes. The probes exhibit temperature/
resistance characteristics described by the relation 1/T = a+b(Ln R) + (Ln R)3 where T is
given in degrees Kelvin. The constants a, b and c are unique for each probe series. The
channel measures the probe resistance by a ratiometric method described below. The CPU
then determines the temperature by evaluating the given equation.

The voltage output of U48B is proportional to the resistance placed in the feedback loop of
U48A. By turning on one of the switches Q8, Q9, or Q10 the resistance selected will be
either the probe or one of the resistors, R2 or R3. These are precision resistors used as
standards for accurate determination of the probe resistance. Resistor R2 is used with probe
series 400. Its value, 3539 ohms 0.025% is equal to series 400 probe at 15ÉC (bottom of
measuring range). Similarly, R3 is used with probe series 700. The CPU “knows” which
probe is plugged in (explained later) and selects the appropriate standard resistor. Following
is the measuring sequence for probe series 400. The probe is selected, by signal TA and Q8,
resulting voltage Up4 at the output of U48B. The voltage is digitized by the 12 bit A/D
converter (U21) and stored by the CPU. Then the standard resistor R2 is measured by turning
Q8 off and enabling Q9 with TB, resulting in voltage Us4. The CPU then calculates the probe
resistance: Rp4 = R2 ! Up4/Us4. Assuming that the circuit gain and measuring current are
stable through the brief measuring period, accuracy of the probe resistance determination is
limited by the A/D conversion process. Using a 12 bit converter, accurate to ½ LSB, worst
case error in terms of temperature is 0.12°C.
Series 700 probes have two thermistors, Th1 and Th2. The first one is used to measure the
temperature, in the same way as described for series 400. The second thermistor is used to
determine which probe series is plugged in as follows: Op-amp U47B compares the voltage
on the ring terminal of the input jack with a threshold of 0.7 volts, from R193 and R177.
When a series 400 probe is plugged in, the ring is shorted to the sleeve contact, which in
turn is tied to the output of U48A. With the switches Q7, Q8 and Q9 off and Q10 on, the
ring voltage is about 1.2 volts and the output of U47B is high. When a series 700 probe is
connected, thermistor Th2, connected between the ring and the sleeve, forms a voltage
divider with R152 at the positive input of U47B. With the switches in the same state as
before, the ring voltage is 0.5 volt or lower and the output of the comparator is low. The
probe type information is used to select the correct set of constants for the temperature
calculation, correct standard resistor and for the selection of the probe measuring current.
The current is adjusted to approximately 330 microamps for series 400 and to 125
microamps for series 700, by means of switch Q7, activated by signal TD. This is done for
optimal utilization of the A/D dynamic range.
The probe jack, located off board, is arranged to short the tip and sleeve terminals when the
probe is unplugged. This provides a zero A/D converter reading as an indication of sensor
disconnect. Primary ESD protection is in the form of a zener diode located at the jack.
Additional protection is achieved by the R106 and C92, as well as the 100 ohm damping
resistors on the gates of Q7-Q10. Because the probe cable capacitance is present at the
summing node of U48A, C7 is used, in conjunction with resistors R92 and R120, to provide
local AC feedback to isolate U48A from the capacitance and ensure stability.
Calibration of the circuit is performed by measuring the two precision resistors R2 and R3 for
equivalent temperature determination. R2 replaces the probe and R3 serves as the standard.
Resulting ratio is R2/R3 = 3539/9428 = 0.37537. Nominally this ratio corresponds to
37.48ÉC. Assuming worst case errors, this number will be 37.5, ±0.1°C.

Power Supply
The Frontend Module is essentially an electrically isolated data acquisition system. The only
portion of this module that is directly connected to the host system is the non-isolated part of
the optoisolators (U15, U17, and U18) used for communications, and the switch mode,
forward converter, isolated power supply.
The isolated power supply (Fig. 2-11) is built around a switch mode converter integrated
circuit, U11. This device outputs two pulse width modulated signals (at pins 11 and 14) to
drive the power transformer T1 with FETs Q1 and Q2. Each of the pulses occurs during its
own respective half cycle of one full period. The half cycle timing is set by R178 and C83.
The modulation of the FET drive pulses is executed by comparing the bulk power voltage
VDC, with a percentage (set by R138 and 179) of the reference voltage on U11 pin 16. In
short, the modulator outputs wide ( 83% of a half cycle) pulses for low VDC values, and
narrow (35% of each half cycle) pulses for high values of VDC. The range of VDC is
specified at 9 volts minimum to 18 volts maximum. The voltage being switched across the
primary of T1 (pins 1, 2, and 3) is transferred to the secondary windings (pins 4, 5, and 6),
and filtered to a DC voltage by components CR30,31,33,36, L1 and L2, and C169 and
C171. The isolated DC voltage will vary between approximately 7.1 volts and 9.3 volts,
depending on VDC and the secondary load current requirement.

This isolated voltage is used as is to supply the analog portion of the module. The digital
circuitry is provided with +5 volts (+5V) generated from the “+7.5" using a simple regulator,
U14. This voltage is also used to produce a +2.5v voltage, created by U13B, R19, and R34,
which is used as a reference throughout the module. The pressure transducer +5T excitation
voltage is generated by a tracking regulator, comprised of U13A, U12, and associated
parts. This voltage ”tracks" the +5v used as the reference voltage for the analog to digital
converter. As a result of doing this, variations of the reference and excitation voltage do not
impact the gain sensitivity (and therefore the measurement) of the pressure transducers,
because the conversion process of the analog to digital converter is linked ratiometrically to
it.
Isolated Microcontroller
For clarity, the isolated microcontroller block as well as the A/D converter and signal
isolation blocks, have been drawn together in the detailed block diagram of Fig. 10. This has
been done because of the close interaction of these blocks. The isolated microcontroller
block on the detailed block diagram consists of a 68HC05 device designated U22. This
device is entirely self-contained, requiring only power, clock and reset for operation. A
3.686 MHz clock is derived from crystal Y2, bias resistor R46, and loading capacitors C46
and C59, together with the internal oscillator circuit in U22. The internal processor clock is
actually this frequency divided by two. The crystal frequency is made available to other
devices on the board. The processor has an internal power-on reset circuit, although its
action is augmented by an external reset. The external reset signal is passed through the
isolation block. The microcontroller can drive its own reset input pin with an internal opendrain device. This must be kept in mind when monitoring reset (pin 1 of U22). In this
application, the processor will attempt to drive the pin low when the internal reset circuit is
activated, which will occur for a brief time after power is applied. Internal detection of
certain failures can also cause the pin to be driven. However, the current software has these
detection mechanisms (COP and clock monitor) disabled.
The device has no external bus, but does feature four general purpose I/O ports. Of these,
port A is programmed as all outputs, and generates the temperature and ECG control lines.
Port B is set to all inputs, and samples the signals supplied by the level shift block. Port C is
set to six outputs and two inputs. The four uppermost bits control the respiration function.
The lower 2 bits are dedicated to the ADC interface. Because all of the on-chip peripherals
are enabled, none of the lines in port D are used for general purpose I/O. Four of these
lines, designated MISO, MOSI, SCK and SS comprise the synchronous serial interface
known as the SPI, which is used to communicate with the A/D converter. Two of the lines,
IRXD and ITXD, carry the serial data received from and transmitted to the isolation block.

Port A Function
The outputs in port A are controlled by the software. The software supports a command
format in which groups of 4 bits can be changed. The lower four bits of port A contain all of
the temperature mode control lines. When a temperature mode control command is received
by the microcontroller, the four bits of data imbedded in this command are asserted on the
lower 4 bits of port A. These four signals are then used by the temperature block to control
analog switches. The upper 4 bits of port A support the ECG function. Upon receipt of an
ECG mode control command, the microcontroller asserts the 4 data bits contained in the
command on the upper 4 bits of port A. The lead select lines pass directly to the ECG block,
while the reset and filter lines are level-shifted, without inversion, by dual comparator U37
and associated pullup resistors, which provide a nominal rail-to-rail swing between the +7.5
and -7.5 volt supplies. The +2.5 volt supply, which is at the midpoint of the logic swing, is
used as the comparator’s reference. Diode D41 allows ORing of the reset signal originating
at the microcontroller with that generated by the ECG subsystem internally. Resistor R249
provides isolation between the comparator and the 2.5 volt supply.

Port B Function
The inputs in port B are read each time a data pocket is sent by the microcontroller, at a
nominal 286 Hz rate. Not all of the signals to be sampled are at proper CMOS logic levels.
Therefore, a level shift network is employed. This consists of a 47K resistor network RN2 and
CMOS inverting buffer U36. The series resistance of RN2 allows this protection network to
clip the input signals, which may swing between the 7.5 volt rails, to a level acceptable to
the buffer. The input protection network will then carry a current of about 150 A, which is
well below the level needed to induce latching. The output of the buffer is then a clean 0 to 5
volt swing.
The software inverts the data at port B, to compensate for the inversion of the level shifter. The
bits are then transmitted in raw form in a data byte known as STATUS within each packet.
The E-trig signal is additionally subject to special processing. The software detects a rising
edge of this signal and reports it in a separate bit in STATUS.
Port C Function
All bits in port C are configured as outputs. The upper three bits support control of the
respiration function. When the microcontroller receives a respiration mode command, the
upper three of the four data bits associated with the command are asserted on the upper
three lines of port C. These three lines control analog switches in the respiration circuit
providing the off/on, reset and filter control functions. The lower two lines of port C are used
as part of the A/D converter interface, and will be discussed in conjunction with the SPI.
Asynchronous Serial Port (SCI)
The TDO and RDI lines in port D provide the asynchronous serial communication interface
(SCI) between the front end and the rest of the monitor, via the isolation block. The
transmission format has a start bit, nine data bits, no parity, one stop bit, and a baud rate of
115.2K. The nine bit format is somewhat unique to Motorola products. It consists of eight
normal data bits, plus one extra bit sometimes referred to as the “address mark” bit. It was
originally intended to designate addressing information in multidrop configurations. In this
monitor, it is used as a means of marking the end of a packet. Each character thus contains a
total of 11 bits, and is transmitted in nominally 96 s. Packets sent from the microcontroller to
the CPU have a variable number of bytes, and consist of several data items followed by a
checksum and terminator. Each data item is internally identified as to its contents. Packets
received by the microcontroller always consist of two bytes, a single command byte
followed by a confirmation.

Theory of Operation
Aynchronous Serial Interface (SPI)
The synchronous serial port, known as the SPI (Serial Peripheral Interface) is used to interface
the A/D converter. The SPI signals are provided in four of the lines in port D. The interface
consists of a shift register with both serial and parallel I/O. In operation, parallel data is first
written to the register, internally in the microcontroller. The generation of eight clock pulses
shifts this data out of the register and into an external peripheral. If this peripheral generates
data, it can be simultaneously shifted into the register. A parallel read of the register will then
provide the input data to the microcontroller. The A/D converter has a serial interface which
is nominally compatible, with the SPI. Note that the clock inputs of the SPI as well as the A/
D converter are connected to port C bit 0. The converter chip select is connected to port C bit
1. The SS line of the SPI, which enables operation when in the slave mode, is hardwired
active low. In operation, the software loads the data to be sent to the ADC (multiplexer
address) into the SPI register. The chip select line is then brought active low, and software
pulses port C bit 0 eight times, generating eight clocks. This transfers the data from the SPI to
the ADC, and loads the eight ADC msb’s into the SPI. The software then reads these bits
from the SPI, saves them, and generates 2 more clocks. The chip select line is then made
inactive, as the ADC has received its exact 10 clocks. Then, with the ADC disabled, six more
clocks are generated, so that the SPI receives a second complete set of eight. At this point,
the SPI contains the two msb’s from the ADC, as well as six undefined bits, which are
discarded.
A/D Converter
The data interface to the A/D converter has been described above, in conjunction with the
microcontroller SPI. The data output line of the A/D converter (U39) is provided with a pullup
resistor (R88) because it becomes tristated whenever the A/D chip select in inactive. In
addition to the digital signals required by the data interface, a clock signal is required for the
actual conversion process. This is obtained from CMOS counter U40, which divides the
microcontroller oscillator by 2, providing a clock of nominally 1.84 MHz. The counter also
provides the oscillator frequency divided by 32. This signal, at nominally 115 KHz, is used
by the respiration block for developing patient RF drive.
The analog inputs are selected by an internal multiplexer. Only eight of the eleven possible
channels are used, with the remainder being grounded. This configuration allows pincompatibility with a 12 bit converter IC. Five of the inputs monitor the patient ECG,
respiration, temperature, and the two pressures. The blocks supplying these signals can
swing beyond the 0 to +5 volt input range of the A/D converter, and must therefore be
limited to prevent malfunction or even destruction of the device. This is provided by a series
of diodes which are connected between each of these signals and both +5 and ground.
These diodes clip the signals to the safe levels. The signal sources have series resistors of
2.2K or greater, which satisfy this requirement.
The A/D converter is of the successive approximation charge redistribution type. It features
an internal capacitor ladder network which is charged from the signal source when the
multiplexer samples a signal.

Block Diagrams
The three remaining A/D converter inputs are used for self-test functions. Input 0 is connected
to a 2:1 ratio voltage divider (R10 and R11) which monitors the +7.5 volt supply, providing
a nominal 3.75 volt test point. The software monitors this input for a low supply condition (10%) only. The -7.5 volt rail is monitored with a divider, consisting of R8 and R9, connected
from the +5 volts to the -7.5 volt rail. This provides a nominal +.83 volt test point, which is
monitored by A/D converter input 7. The software is designed to sense a 10% drop in the 7.5 volt rail. Both of these A/D converter inputs have diode protection, and are furnished
with small capacitors to filter any transients. The +2.5 volt supply is directly connected to
input 6, and is tested by the software for both high and low conditions. The A/D converter
also generates an internal, half-scale, test voltage, which is similarly monitored. A failure of
any of these supply voltage tests is reported in the STATUS field of the data packets. Because
extreme accuracy is not needed in these measurements, the software checks only the upper 8
data bits. Significant measurement uncertainties can result from the resistor tolerances,
converter input leakage current, input charge, and reference (+5 volt supply) tolerance.
These factors are taken into account in the setting of the limits, to prevent false reporting of
errors. Additionally, a supply fault must be detected by the software on two successive tests
before it is reported.
The A/D converter has a pipelined structure. Each time the SPI communicates with the
converter, it writes the multiplexer address for the next conversion to the converter, and reads
the result of the previous conversion. The next conversion starts as soon as the address is
written. The software then engages in other activities while waiting for the conversion to
finish. Thus, the data read from the A/D converter lags one sample behind the current
multiplexer address. The software takes this delay into account when formatting the data.
The A/D converter has two +5 volt and two ground connections. Although these eventually
connect to common points, they are run on separate traces to minimize noise and errors due
to trace impedance and interaction with other loads. Operating power for the A/D
converter, on pins 10 and 20, is supplied from the digital branch of the +5 volt rail, and
returned via the digital portion of the ground plane. Capacitor C 120 directly bypasses these
points. The reference voltage, at pins 14 and 13, is supplied from the analog branch of the
+5 volt rail and the analog ground plane half. The same reference is used excite the pressure
transducer bridge. The temperature function makes use of the ratio of two A/D converter
readings and is thus independent of the exact reference value.

Signal Data Isolation
The signal data isolation block provides communication across the patient isolation barrier.
Serial data originating at the microcontroller’s TDO pin is inverted by one section of U36. It
is then buffered, and inverted again, by transistor Q10 and R230, which operate as a
saturated switch. The collector circuit of Q10 includes the LED of optocoupler U42 and
current limiting resistor R229. The TDO pin idles at a logic high state, and has bursts of low
level pulses during actual data transmission, which occurs at a low duty cycle. The driver
configuration used results in the LED being “off” most of the time, conserving power. The
optocoupler, U42, provides the actual isolation. The optocoupler features a separate
photodiode and amplifier transistor, providing the good high frequency response required to
support the 115.2 K baud data rate. On the non-isolated side, the open-collector output of
U42, together with pullup resistor R233, produce a CMOS logic compatible signal. This
signal has the same polarity as that on the TDO pin, and is routed to the Control Module
CPU via J42 pin 3.
Serial data originating at the Control Module CPU is connected to J42 pin 4. Transistor Q13,
R235, and R238 are used to invert this data, which is then buffered and inverted again by
Q11. The collector circuit of Q11 contains the LED of optocoupler U43 and current limiting
resistor R234. Note that U43 is driven in the same way as U42, described above. On the
isolated side, the open collector output of U43, together with pullup resistor R231, produce a
CMOS compatible signal, which is connected to the RDI input of the microcontroller, U38.
The Control Module CPU can cause a reset of the front end microcontroller by asserting a
logic high level on J42 pin 5. Via R237, this signal will saturate Q12. The collector circuit of
Q12 contains the LED of optocoupler U14 and current limiting resistor R236. Thus, the
optocoupler is turned “on” when the reset signal is asserted. On the isolated side, the
optocoupler transistor then pulls the RESET pin of the microcontroller low, against pullup
resistor R232. When the Control Module CPU returns J42 pin 5 to a low level, the RESET pin
will go high and microcontroller operation will begin.

SpO2 Board
Overview
SpO2 board consists of analog and digital sections. Analog section provides all the patient
finger probe excitation and analog signal processing. Digital section controls the operation
of analog part of the board and shares its RAM with an external processor via ISA bus.
A pulsatile arterial saturated oxygen monitor detects the oxygenation level of the blood in the
body’s arterial circulation. It is used to continuously monitor the effectiveness of the
pulmonary system (lungs). Specifically the device, within limits, determines the fraction of
hemoglobin molecules carrying oxygen from the lungs to the body cells. Termed % SPO2,
this fraction is normally about 97 percent.

Passport 5-Lead, 5L, LT, XG Service Manual
Theory of Operation
Block Diagrams
The device measures the relative attenuation of two specific wavelengths of light (red and
infrared) by the arterial blood. A sensor from the instrument contains two sets of LED’s to
illuminate a portion of the body (e.g., a fingertip), and a single photo-detector to sense the
amount of light which exits. The two sets of LED’s are alternately pulsed so that the circuitry
can discriminate the infrared light. Each time the heart pulses arterial blood into the finger,
the photo-detector’s signals return to their original level. The electronic instrumentation
processes only this changing portion of the photo-detector’s outputs.
The determination is based upon the assumption that hemoglobin and oxyhemoglobin are
the only two significant attenuators of light in the arterial blood. The device exploits the
difference in their optical attenuation characteristics. But since the detector’s signal is
sensitive to the combined attenuation of both molecules, the device must use two different
wavelengths to discriminate their individual contributions, and thus their relative
concentration.

Theory of Operation
Analog Section
The operation of the analog section is controlled by the digital part of the board by:
• Supplying CLKSEQ clock signal to the sequencer.
• Latching signals D0..7, into control register with strobe signals APOUT0, APOUT1, and
APOUT3.
• Monitoring COMPOUT* and INTERF* signals.
Sequencer controls the front end of analog section. It provides RED DRV and IR DRV
signals for led drive circuit which in turn alternately drive red and infrared LED emitters in the
probe. A single photo-detector on the opposite side of the finger produces current pulses
proportional to the amount of light received. Sequencer also sets the gain of the current to
voltage pre-amp and controls the demultiplexer. Gain values for current to voltage pre-amp
are derived from control register signals IR0, IR1, RED0, and RED1. The fact that the
sequencer has synchronous control of led drive, gain of current to voltage pre-amp, and
demultiplexer makes it possible to set different current to voltage gain values for infrared and
red signals.
Control register provides data for the DAC and sets gain values of dc gain (DCG0, DCG1) ,
ac gain (ACG0, ACG1), and current to voltage pre-amp (IR0, IR1, RED0, RED1) stages.
Wide gain range gives the board enough flexibility to acquire signals from fingers spanning
a wide range of thicknesses or alternatively from other sites of the body such as ears, noses
or toes. It also controls the remultiplexer (CHNLMUX) and provides calibration signal
RUN/CAL, which is used by the sequencer to determine the operation mode, and test signal
DIAG, which supplies a fixed voltage source at demultiplexer input for circuit diagnostics.
Again because control register can synchronously control the remultiplexer and gain values
for ac and dc gain stages, different gain settings can be selected for red and infrared
signals.
Interference detector monitors the output of current to voltage preamp for voltages less than 7.2 V in amplitude. This information is sent to the digital section through INTERF* signal.
The probe patient signal enters the board as current pulses in the range of .48 - 64 A. After
signal goes through current to voltage preamp stage it is separated by the demultiplexer
circuit, which steers each voltage pulse to one of two signals A and B. In addition, the circuit
sends a negatively amplified version of the signal level between LED pulses to both channels.
This residual signal is caused by ambient light on the photo-detector and offset voltages from
the preceding circuitry. The negative amplification sets-up cancellation of the extraneous
effect of the residual signal by the filter circuits that follow.
Signals A and B are then filtered identically by two parallel and matched filters. Filters also
reduce the effect of any noise source, which might interfere with the measurement, such as an
electro-surgical unit.
After going through filter blocks red and infrared signals and are alternately selected by the
remultiplexer for further processing. Next signal is amplified by the dc gain stage. Having
the ability to apply a different gain to the two components, this block functions as a coarse
equalization of the multiplexed signal.

An offset voltage, determined by the DAC, is then subtracted by the subtraction circuit. The
plethysmographic waveform consists of a small component varying along with the
physiological pulse, sitting on top of a larger pedestal. Subtraction circuit pulls off most of
this pedestal. Subtraction circuit also helps to maintain the resultant signal in the amplifier
linear region.
The residual multiplexed signal is once again processed through a microprocessor controlled
ac gain block. One of a few discrete gains is chosen for each of the two components, such
that the peak to peak size of the physiologically varying components is large enough to be
digitized with sufficient resolution.
After going through the ac gain stage the signal is sampled by sample and hold and held for
amplitude digitization. The digitization is performed under the microprocessor control of the
digital to analog converter. The DAC voltage is successively altered by the microprocessor
until it zones in on the signal being digitized. Comparator then compares signal and DAC
voltages and sends COMPOUT signal to the digital section.
The DAC thus performs a dual function. It is used in both the subtraction and the comparator
blocks. Every 1/240 of a second, the circuit’s control functions are flipped to process the
alternate component of the multiplexed signal. The multiplexer switches signals, the two
microprocessor controlled gains are changed, if necessary, and a new digital code is sent to
the DAC for use in the subtraction circuit. After settling to it’s new value, the signal at the
input of the comparator is frozen by sample and hold circuit. The DAC is now available to be
used in the digitization. At the next 1/240 second interval, all the control signals revert to the
previous values.
Digital Section
Digital section of the board performs two distinct functions: analog section control and ISA
bus interface.
First is based on 63C09 microprocessor. Analog section is accessed by writing data into
control register. Address decoding for generating control register strobes APOUT0,
APOUT1, and APOUT2 is done by 63C09 to analog interface. The same interface is also
responsible for monitoring status lines COMPOUT* and INTERF*. 63C09 can observe the
status of these lines by reading RD0 from the assigned memory location.
ISA bus interface allows an external processor to access SRAM and to halt and clear the
63C09 processor. Shared SRAM control is achieved by allowing 32Kx8 SRAM to be
accessed by 63C09 as well as an external processor through ISA Bus. Address bus is
shared by using 63C09 TSC signal. TSC (Tri-State Control) causes 63C09 address, data,
and R/W* buffers to assume a high-impedance state. When a valid ISA bus access cycle is
detected it is synchronized using ISA IOCHRDY signal. Because ISA access cycle is
synchronized to 63C09 clock, 63C09 always has SRAM access priority over ISA bus cycle.

Theory of Operation
ISA bus processor can control 63C09 operations by accessing CLR* (63C09 reset), HALT*
(6309 halt), and FIRQ* (63C09 fast interrupt request) signals. These signals are set by
writing to an assigned address location and reset by reading from the same location (See ).
Although hardware assures proper powerup conditions of these signals, they should still be
initialized by external processor software.
Control Register
Control Register consist of three 74C374 octal D flip flops (U17, U18, and U19). When
data is written into corresponding memory address space one of three strobe signals
(APOUT0, APOUT1, or APOUT3) is activated and data is latched to the output control
signals. Only 63C09 processor can access the control register. Table II, and Table III show
how data lines are mapped to the control register outputs.

Sequencer
The primary function of the sequencer is to synchronize the LED drive signals with those that
control the sequential demodulation of the photodetector’s amplified output.
The sequencer also directly controls the switches U3A, U3B, and U3C, which set the current
to voltage preamp gain. Since the gain required for the transmitted red light may differ from
that required for the transmitted infrared light, synchronization of the gain control switches
with the drive signals is also required.
Finally the last function of the sequencer is to cancel the residual signal and any low
frequency signal noise. The sequential demodulation process for each wave-length subtracts
from the detector’s signal when the LED is activated, the residual signal that exists when the
LED is not activated. This cancellation process works only for residual signals at frequencies
significantly lower than the drive frequencies of the LED’s (about 1.3 kHz). The interfering
signals it works against are primarily:
The sequencer is composed of an EPROM U24, a counter U23 and a latch U25. The eight
bits of the counter are fed to the eight least significant address bits of the EPROM. The
microprocessor provides the five most significant address bits trough the control register.
The five control signals are changed infrequently but the counter increments every 16 s at the
falling edge of the CLKSEQ clock. Thus the EPROM may be thought of as containing 32
(25) sequencer programs. The one chosen by the five microprocessor signals is cycled in a
continuous loop.
The program length would be constrained to be 256 steps if not for the counter reset logic
(U26A and U26D). Counter is reset whenever address bit 5 and red drive are both active.
Reset logic allows flexibility in the choice of cycle length.
The outputs of the EPROM are the control signals for the LED drivers (RED DRV and IR
DRV), sequential demodulation process in the preamp (S3, S4, S5, and S6), and the gain
setting for the current to voltage preamp (S1 and S2). They are latched by the rising edge of
the CLKSEQ clock signal for precise timing relationships.
LED Drive
LED Drive circuit interfaces TTL LED drive signals (IR DRV and RED DRV) to red and infrared
LEDs. It consists of two circuits: LED voltage source and LED driver switch.
LED voltage source provides voltage to anodes of both LEDs and acts as intermittent short
circuit protection device. Under normal operation Q1 is “ON” and Q4 is “OFF”. When a
short circuit condition occurs higher current will cause larger voltage drop across the resistor
R24. This will turn Q4 “ON” and Q1 “OFF”, cutting off the voltage supply to the sensor.

Block Diagrams
Theory of Operation
LED driver switch consists of two similar circuits one for each red and infrared LEDs. TTL
pulses are limited to 3.35V by combination of CR5/R29 (CR6/R30). This is done to assure
undeviating LED current. Signal is then AC coupled by C18 (C19) and is used to switch Q2
(Q1). Transorbs CR10 and CR11 are used to provide ESD protection.
Current to Voltage Preamp
The function of Current to voltage preamp is to convert current pulses from sensor’s
photodetector elements to voltage pulses. It is based on U1A and U2B. Preamp gain value
is selected by 63C09 processor through the control register and sequencer (). Signals S1
and S2 are used to control the switches U3A, U3B, and U3C, which change the U1A
feedback resistor value.
Demultiplexer
Under sequencer’s control, demultiplexer separates the signal into red and infrared
components and subtracts DC offset and low frequency noise from the signal. Switches U5A
and U5D route the direct and inverted output of current to voltage preamplifier into red
channel (A). Switches U5B and U5C perform the same function for infrared channel (B). U6
and U7 are configured as integrators, which average inverted and noninverted signals.
Matched 18 Hz Filters
Two identical low pass filters, based on U8 and U9, provide noise rejection for LED and
demultiplexer switching noise (f1.366 KHz) and ESU noise (f500 KHz). Each filter consists
of two equivalent dual pole low pass filters, which when cascaded, provide 80 db per
decade roll off with f018.9 Hz.
Remultiplexer
Remultiplexer is controlled by 63C09 processor by toggling the CHNLMUX signal (See ).
This signal regulates switches U10A and U10D, which steer either red or infrared signals
into Programmable Gain I stage.
Programmable Gain I (DC Gain)
Programmable Gain I block is also controlled by the 63C09 processor through the Control
Register. U11A is configured as noninvering amplifier with the gain selected by state of
signals DCG0 and DCG1 (See ). This stage amplifies both AC component of the signal and
it’s DC pedestal.
Subtraction and Programmable Gain II (AC Gain)
In this block U11B is configured as an inverting summing amplifier. Two inputs to the
amplifier are red/infrared signal and output of the Digital to Analog Converter. This
configuration allows the output signal of the DAC to be subtracted from the red/infrared
signal. Subtraction function is used to get rid of most of the signal’s DC pedestal. The circuit
then amplifies the resulting signal according to the gain set with signals ACG0 and ACG1.

Sample and Hold
Sample and Hold consists of U13. The purpose of this circuit is to hold the signal at a
constant level, while the signal digitization is in progress. Sample and Hold is controlled
using the signal S/H according to below. Hold capacitor C35 is selected to provide
acquisition time 20 sec and droop rate 3mV/sec.
Comparator
Comparator is based on U14. It compares the signal held by sample and hold to the output
of the DAC. Output of the Comparator is a signal COMPOUT* (See). 63C09 processor
writes a value into the DAC and then checks the status of this signal. The procedure is
repeated until signal is digitized with the acceptable resolution.
Digital to Analog Converter (DAC)
Digital to Analog Converter consists of U20 and U21. 63C09 processor can access 12
digital inputs by writing into the control register. The analog output signal is connected to
input of sample and hold and subtraction input of Programmable Gain II block.
Interference Detector
Interference Detector monitors the output of Current to Voltage Preamp. U2A configured as a
comparator, which detects voltage levels more negative than -7.2 V. When this level is
detected INTERF* line goes “low”. 63C09 CPU monitors this line to detect when Current to
Voltage Preamp is saturated.
Clock Generator
Clock Generator consists of 11.0592 MHz crystal oscillator Y1 and five D flip-flops U42,
U43, and U47. 11.0592 MHz OSC clock is divided in half by U47A, which outputs two
complementary clock signals: SYSCLK and SYSCLK*. These two clocks are used as a
baseline for digital section timing.
Parallel Interface
Parallel Interface consists of input buffers U31, U32, U33, and U34, output buffer/register
U35, and Q6. It’s function is to buffer the signals to/from ISA bus connector J1. Tri-state
signals of ISA address buffers U31 and U32 are controlled by the signal SROE, data input
buffer U34 is enabled by ISA-WR-OE*, and data output buffer/register is enabled by ISA-RDOE* and clocked by ISA-RD-CK*. All of these signals are generated by ISA Bus Interface.
ISA Bus Interface
ISA Bus Interface performs several distinct functions:
• ISA Bus Address Decoder
Address decoder section of ISA Bus Interface generates SRAM control signals (SRCE* and
SRWR*) and 63C09 processor signals HALT*, CLR*, and FIRQ*. SRAM signals are derived
from inputs SA16 through SA19 according to timing relationship described later in the
document. 63C09 signals are asynchronously set (disabled) when a valid write cycle is
detected and reset (enabled) during the read cycle.

Theory of Operation
• CLKSEQ Counter
CLKSEQ signal is used by the Sequencer. To generate this signal E clock divided by 22,
which produces CLKSEQ frequency of 62.836 KHz. Signals BIT0, BIT1, BIT2, and BIT3 are
used internally for the counter.
• ISA Access Timing Control
This section is based on U37 PLD. It is responsible address and data bus arbitration and
SRAM signal timing. In order to understand system timing, it is necessary to know how
63C09 TSC signal works. TSC (Tri-State Control), when enabled, causes 63C09 address,
data, and R/W buffers to assume high impedance state. When TSC is enabled these signals
are tri-stated after the next falling edge of E clock (See and ). 63C09 signals resume valid
levels after TSC has been disabled.
When a valid ISA access occurs (MEMW* or MEMR* active during a valid address)
IOCHRDY signal is asynchronously disabled. Access is then synchronized to system clock
and, when busses are available, ISA address buffers are enabled (using signal SROE).
SRAM (SRCE* and SROE*) and data bus buffer (ISA-RD-OE*, ISA-RD-CK*, and ISA-WROE*) control signals are generated next. Finally IOCHRDY is enabled, completing ISA
access cycle.
63C09 to Analog Interface
This section is based on U41 PLD. It is responsible for generating APOUT0* through
APOUT2* Control Register strobes and monitoring the status of COMPOUT* and INTERF*
signals according to the 63C09 memory map (see ). It also generates the ISA IRQ5 signal,
which is always disabled. It is pulled up on CPU board and is used to detect whether SPO2
board is present.
Static RAM
32 K x 8 Static RAM is shared by 63C09 and external processors. Software code for 63C09
processor is downloaded into SRAM via ISA bus. Static RAM is then used by 63C09
processor to fetch instructions, store data, and communicate with the external processor.
63C09 CPU
Main function of 63C09 CPU is supervision of analog signal processing and digitization.
This is accomplished by manipulating gains of C/V, AC, and DC amplification blocks and by
controlling Sequencer, DAC, Remultiplexer, and Sample and Hold sections, while monitoring
COMPOUT* and INTERF* outputs. Control of the blocks mentioned above is achieved
through Control Register.

Masimo/Nellcor SpO2 Interface Board
Overview
The Passport Masimo/Nellcor SPO2 Interface Module, (0670-00-0665-01= Masimo, -02 =
Nellcor) or PM/NIM, provides the electrical interface between the Passport monitor and a
Masimo or Nellcor OEM Pulse Oximetry Module. The PM/NIM provides both buffered data
communications as well as power supplies for the Masimo or Nellcor Module.
FIGURE 2-14 Masimo/Nellcor SpO2 Interface Module Block Diagram
An overall block diagram of the PM/NIM is shown above. Bus interface logic, consisting of
a programmable logic device, an octal register, and an octal buffer, connects to the
Passport’s pseudo-ISA bus. This bus is shared with the CO2 module. Therefore, bus resources
have been allocated to avoid conflicts. This interface logic implements two read-write
registers, one for data and the other for control or status. A 68HC705 microcontroller
operates as an intelligent, buffered UART. The serial port of the microcontroller provides the
data interface to the SpO2 Module. All microcontroller data and control lines interfaced to
the SpO2 Module are opto isolated. Power to the SpO2 Module is isolated by a DC-DC
converter module with its input coming directly from the Line/Battery Supply Module.
The SpO2 Modules communicate serially at 9600 baud. A microcontroller is used as a
“smart” UART. A microcontroller can be programmed to understand either the Masimo
protocol or the Nellcor protocol, and can thus buffer the data in an intelligent manner.

Block Diagrams
Theory of Operation
When serial data is received from the Oximeter Modules, the microcontroller buffers the data
until a complete packet has been received. The packet is then validated by means of a
checksum. If valid, the microcontroller makes the first byte available to the bus interface
logic, and interrupts the Passport CPU. The Passport responds by reading the first byte. A
flag indicating the availability of data (first and subsequent bytes) is provided in the status
register. By polling this flag bit in a tight loop, the CPU is able to read the subsequent bytes.
The CPU is able to identify the packet’s byte count based on the first byte read, and therefore
knows how many additional bytes to read by polling.
A similar procedure is used to transmit serial data. The CPU polls a busy flag in the status
register. When this flag is clear, one byte of data is written to the PM/NIM. The busy flag
becomes immediately set. As soon as the microcontroller accepts and buffers this data, the
busy flag is cleared by the microcontroller, so that the CPU can write the next byte. This
process continues until an entire packet has been written. When an entire packet has been
written, the PM/NIM validates the packet by means of the checksum, and proceeds to
serially transmit it to the SpO2 Module.
It is possible to assert or remove reset to the microcontroller by writing to the control register.
Whenever the ISA bus signal RESETDRV is active, the microcontroller reset will be asserted,
and will remain asserted after RESETDRV is no longer active. Internal power-on-reset logic in
the EPLD asserts reset in a similar way. . As the microcontroller passes from the reset to the
active state, it activates the SpO2 Module reset line and enters a data echo mode. Only
after receiving a command from the host will it exit the echo mode and release the SpO2
Module reset. This insures a coordinated start-up of the PM/NIM and SpO2 Module.
Read-Write Logic
The figure below shows the portion of the EPLD, U4, which provides the read and write logic.
The four most significant ISA address lines, SA16..SA19, are decoded. Two ports are
needed, one for control and one for data. The selected port addresses are at ISA 80000
hex for data and ISA 90000 hex for control/status. These correspond to 900000 hex and
920000 hex, respectively, in the Passport CPU address space. The address assignments are
unique to allow the Passport to easily determine on bootup which modules are connected to
the ISA bus. The Passport software accomplishes this by attempting to address the module.
If it is not present, a bus exception occurs indicating the absence of a working PM/NIM.
When an OEM SpO2 module is used in the Passport a Software command is used to
determine whether a Masimo SpO2 Module or Nellcor SpO2 Module is present.
When a write is made to the status port address, the inverted state of D0 is latched in flip-flop
F/F 3 inside the EPLD, U4 (Figure 2-14 on page 2-35).
2 - 36
0070-00-0420
Passport 5-Lead, 5L, LT, XG Service Manual
Theory of Operation
Block Diagrams
FIGURE 2-15 EPLD, U4 Block Diagram
The output of F/F 3 drives the microcontroller’s active-low reset line. Thus, if D0 is high
during this write, the microcontroller will be placed in reset. Conversely, if zero is written,
microcontroller operation will begin. This flip-flop is also cleared by RESETDRV as well as the
EPLD’s internal power-on reset logic. Thus, at power-up, the microcontroller will be held reset
until zero is written to the status port, allowing an orderly start-up. The RESETDRV signal is
filtered by R3 and C11 to minimize the possibility of false triggering due to ESD events.
When a write is made to the data port, a decoded write pulse (CK/IRQ) clocks U2, latching
the data from the bus. This same pulse also interrupts the micro-controller (U1), telling it that
new data has arrived. Also, flip-flop F/F 1 inside U4 becomes set (see figure on previous
page). The Q output of F/F 1 can be read on data bus line D1 when a read is made to the
status port address. When the microcontroller responds to the interrupt, it clears F/F 1 by
pulsing CACK* low. Thus, bit D1 at the status address acts as a “busy” flag, which becomes
set immediately after data is written, and is cleared when the microcontroller has assimilated
the data.
When the microcontroller has data to be transferred to the ISA host, it presents the data via
port A to the tristate buffer U3. It then pulses the line STRB* low, setting F/F 2 in U4. The Q
output of this flip-flop can be read in bit position D0 of the status port. Thus, the ISA host can
poll to determine when data is available. A 1K resistor, R2, limits the current when the CO2
module drives the line high.

Block Diagrams
Theory of Operation
When the host polls the D0 bit and finds it active, it then reads the PM/NIM data address.
The EPLD decodes this into a read pulse (OE*) which enables the tristate buffer, U3, driving
the data on the bus. This action also clears F/F 2, so that IRQ 5 (were it enabled), as well as
the data available bit in the status port, are immediately dropped. The data available flag is
also available to the microcontroller as BFULL, which is connected to port C. After the
microcontroller asserts new data, it waits for the BFULL line to become low, indicating that the
host has accepted the data, before asserting the next byte.
IOCHRDY Logic
The pseudo-ISA bus in the Passport differs from a true ISA configuration in the implementation
of IOCHRDY. In the Passport, a rising edge must appear on IOCHRDY while SMEMR* or
SMEMW* is active in order to complete the bus cycle. A steady high level is not sufficient.
The EPLD contains the logic shown in figure below for generation of IOCHRDY.

The address lines SA16..SA19 are decoded to generate a signal whenever either port (data
or control) on the board is selected. The D input of F/F 4 is high whenever a read or write
occurs and the board is selected. Before a bus cycle begins, the outputs of F/F 4 and F/F 5
are both low. These flip-flops are clocked by an on board crystal oscillator, at 3.6864 MHz.
Microcontroller
The microcontroller manages the flow of data between the host and the SpO2 Module. It
consists of a 68HC705 single chip microcontroller. It operates at an oscillator frequency of
3.6864 MHz, obtained from an on board crystal oscillator. The oscillator also provides
clocking for U4.
When it is brought out of reset, an internal self test is performed, which verifies the PROM
contents and RAM operation. During this self test period, lasting several ms, bit 4 of port C,
SRST*, is configured as an output and driven low. This asserts reset to the SpO2 Module.
The PM/NIM then enters a data echo mode.

Any data written to the PM/NIM data port is accepted by the microcontroller on port B.
Data to be sent to the host is asserted on port A. Communications with the SpO2 Module
take place by a CMOS level asynchronous serial link in J23. The parameters are 8 data
bits, even parity, one start bit, one stop bit, with the data having “true” polarity. The baud
rate is selectable under U1 software control as 9600 baud.
SCTS* on port C bit 5 is used to enable the Flash Programming voltage on the Interface
board. To allow the in-system programming for the MS-1 SpO2 Module this signal should be
set High. SCTS* on port C bit 5 also allows U1 to suspend transmissions from the Nellcor
Module.
Power Supplies
The Power for the OEM SpO2 module and Interface board is derived from a combination of
the system +5V and the Switch_Bulk_OUT supply. The isolated voltages for the OEM SpO2
board is derived from the Switch_Bulk_Out supply, this bypasses one DC/DC convertor and
its associated inefficiencies. The power consumption of the OEM SpO2 board and Interface
board should be similar to that of the Datascope SpO2 module.
The Masimo SpO2 module requires four isolated voltages: +5V, +/-15V, and +12V.
The Nellcor Module requires four isolated voltages; +5 volts, +/-15 volts and -6 to -15 volts.
The latter voltage is tied directly to the -15V supply on the PM/NIM by connecting J23 pin 6
and 7. This prevents the need for jumper JP4 on the Nellcor Module which would otherwise
accomplish the same task. Also, the additional power needed to drive this voltage with -15
volts versus -6 volts (if it were available) is negligible since the maximum current needed for it
is only 5.3mA.
The isolated +5 voltage is generated and isolated by DC-DC converter, VC1. The +/-15V is
derived from the isolated +5V convertor and is generated by a Boost Switching regulator. A
N-Channel Mosfet controls the +5V voltage level seen by the SpO2 board. The Gate of the
Mosfet is connected to the +15V Regulator and the +5V is connected to the Drain. This
allows the +/-15V source to always lead the +5V by at least +0.3V as required by the
Nellcor Module power supply sequencing requirements. An additional 5K ohm load was
added to the +15V to assure that the +/-15V switching regulator will stay in the continuous
mode when lightly loaded by the Nellcor module.
Additionally there is a +12V switched capacitor supply on board to supply the Flash
programming voltage and current required for in-system software updates for the Masimo
SpO2 module. The +12V supply derives its input from the isolated +5V supply. The +12V
supply is controlled by the SCTS* output of the micro-controller. This voltage should normally
be turned off to give added protection against the flash memory being overwritten, and to
eliminate load and noise from this supply. In order to disable this supply voltage, the SCTS*
line must be taken to a logic level Low.

Signal Isolation
The interface signals to and from the Oximeter Modules are isolated by five optocouplers,
U7 through U11. The low duty cycles of the signals holds the power requirements to
reasonable levels.
Schmitt trigger inverters are used at the optocoupler outputs due to the slow rise and fall times
of the couplers. This provides a clean output edge with no bouncing and reduces timing
skew. The U11 output requires no such Schmitt buffer due to debouncing hardware built into
the U1 microcontroller. Other inverters are used in the circuits to provide the necessary
inversions for proper signal polarity and to force the optocouplers normally off.
All of the U1 signals to and from the Nellcor Module to be normally high with the exception
of CTS*. This signal should be normally active low and only become inactive if Nellcor
Module data transmissions must be suspended.

CPU
Device U1 is an MC68302, which contains a 68000 core CPU and much of the peripherals
used in the Passport PCM board. The CPU contains a 24-bit address bus and a 16-bit data
bus. Along with Y1, and a resistor/capacitor network, U1 shall operate at a clock speed of
16.5888MHz. This clock rate is the highest clock rate that the MC68302 can operate while
being a multiple of the baud rate of 115.2Khz for Front End communications.
There are 4 programmable chip select/wait state control groups. They are listed in below.

Datasette
The Datasette provides program memory and data storage for the main CPU module in the
Passport.
The Datasette contains two 512Kx8 FLASH ROM ICs and two 128Kx8 Static RAM ICs. They
are accessed by the host CPU via two chip select lines; even (CSL*) and odd (CSH*). Both of
these chip select signals should be decoded for the first 4 megabyte of the host’s memory
address space. The host module must decode the A0 address line to generate the even and
odd chip selects. Further decoding is provided by U5. The address space which is allocated
by the host CPU module consists of 2x2 megabyte regions. The first region (0000000x1FFFFF) is allocated for ROM use. Only one megabyte of FLASH ROM is used, therefore
the ROM is mirrored in the first and second megabyte of the address space. The upper 2
megabyte region (0x200000-03FFFFF) can be subdivided into 8x256K or 4x512K regions.
The 256K of RAM on the Datasette is decoded to respond in the upper half of each of the
512K regions.
A jumper, J1 has been added to the module to allow for use in a commercial PROM
programmer. Most PROM programmers have the capability of obtaining manufacturer and
device IDs from the device. This is possible by applying a higher than normal voltage at the
input address pin, A9. This voltage may be alright for the FLASH ROMs on the Datasette, but
it will cause damage to the static RAMs on the Datasette. To prevent this possible damage
from occuring the jumper J1 was added. When J1 is installed the address signal A10 is
connected to the A9 input pin of the SRAMs. This is necessary when the Datasette is
operating inside a Passport. This jumper must be removed if the Datasette is to be used in a
PROM programmer.
The CPU module operating at 16.5888Mhz will necessitate the use of 1 wait state to access
SRAM and 0 wait states to access FLASH ROM.

Non-Volatile RAM
This memory made up of two 128Kx8 120 nsec. SRAMs, U2 and U3. The memories are
non-volatile due to the circuitry of Micromanager U21, Battery BT1, R17, and D4. The initial
start address of the RAMs is at 400000H and is mapped to a 2M byte space. Chip select
line 1 is used by the CPU, and will have a wait state of one cycle. Initially only 256K bytes
should be enabled.
Video RAM
The video memory consists of a 32Kx8 120 nsec. SRAM, that is initially mapped to 64K
bytes starting at 600000H. Only the lower byte of the video memory is used (8 bit bus
mode). The LCD is a 640x200 display that will be supported with the current memory size.
The memory can be expanded to a maximum of 128K bytes for larger size displays.
This memory is dual-ported to the CPU and the display controller. A variable number of wait
states will be inserted because of the asynchronous nature of the CPU accesses to video
memory. The SCT bit in Bank Address 23H, data bit D7 of the display controller should be
set to a 1 to minimize wait time.
Display Controller
The display controller, U5, is a Yamaha V6366. The clock is provided by U38, an
11.0592MHz oscillator. The LCD that is being used on the Passport project can
accommodate a 4-bit parallel data bus. Therefore, U5 is set up for 4-bit display operation.
At the clock rate, and parallel data transmission, a transaction will last for 361 nsecs., which
will meet the minimum LCD cycle time of 330 nsecs.
The display controller outputs, CSY, BLA*, BST, AC, LD.0 are used to drive a 640x200 LCD.
The display interface signals can be disabled by the LDEN* signal (port B bit 1, U1-109).
On power-up or reset, this bit is default to an input, which will automatically disable the
display, thus preventing unorganized or old data to be displayed.
Another signal BLEN* (port B bit 2, U1-110) is provided to disable the LCD bias voltage,
VEE. This signal should not be active (low) until the display controller has been initialized,
assuring proper timing signals for the LCD. This signal works similarly to the LDEN* signal,
in that on power-up or reset, the LCD is automatically disabled. Upon a power-up/reset
situation, the display controller should be initialized as soon as possible.
The display controller outputs VSY, HSY, and LD.4 are also connected to the external
interface connector , but are not used at this time.

Interrupt Controller
The interrupt controller is controlled by addresses 812H to 81CH within the 4K peripheral
control block. In addition to the 16 on-chip interrupt sources (on priority level 4), 3 external
interrupts are supported (on levels 7,6, and 1). The external interrupts should be
programmed to be dedicated level-triggered mode interrupts. Currently IRQ1* is used (for
the AR-42 Recorder error line); IRQ6* and IRQ7*, which is non-maskable, is not used. The
interrupt acknowledge and autovector mode feature is not used; the interrupt controller
should be programmed to provide the interrupt vector. The upper 3 vector bits can be
programmed to anything other than 000 and 001, such that the interrupts are mapped into
user interrupt vector space.
The external and internal interrupts can be summarized as follows:

8-bit D/A Converter
The 8-bit D/A converter, U36, is connected to the upper byte of the data bus. The address of
the D/A converter is set to 720000H for byte access. This mapping is such that it falls under
the chip select 3 timing. This device requires a 240 nsec. write pulse. This is the worst case
timing on chip select 3. With 3 wait states inserted, the pulse with respect to UDS* is 241
nsec., which is barely met.

Block Diagrams
Theory of Operation
The output of the 8-bit D/A converter is multiplexed to two outputs: the external analog output
and the volume control voltage. The multiplexing is controlled by two sample and hold
control signals: ANEN* and VLEN*, controlled by port A bits 4 and 5 of the CPU
respectively. A zero in those bits will sample the voltage from the D/A converter and a one
will hold that voltage at the sample and hold.
Analog Output
The external analog output is used to output the ECG waveform. It is biased to be a bipolar
signal (+/-5V) by U36, U33, and R16/C78 bias network. A 00H code would output -5V
and an FFH code would correspond to +5V. The update rate should be 286Hz. The 10-bit
ECG sample from the front end should be scaled down to 8-bits (truncating the lower order
two bits) and output directly to the D/A. In order for the voltage at U34-6 to reach the 8 bit
lsb accuracy of the D/A, the switch should be held closed for at least 20 usecs. No other
writes to the D/A should occur within 20 usecs. Since the ECG is updated at a rate of 286
Hz (3.5 ms), there should be no problem from this half of the converter.
An analog simulation of the circuitry shows that it shall meet the specification of .5 to 40 Hz
@ -3db.
Speaker Driver
The volume voltage is unipolar. A 00H code would be lowest volume (silence) and FFH
would be highest volume. The loudness perception is not necessarily linear and some trial
and error may be needed to yield the corresponding sound levels desired for presets.
The digital switch for the speaker driver circuitry shall be held closed for at least 912 usecs.
in order to get the accuracy as discussed earlier.
The operation of the sample and hold should be as follows:
• Turn off both sample and holds (ANEN* and VLEN* high)
• Output volume value to D/A converter
• Turn on volume S/H (VLEN* low)
• Wait at least 912 usec
• Turn off volume S/H (VLEN* high)
• Output ECG value to D/A converter
• Turn on analog output S/H (ANEN* low)
• Wait at least 20 usec until starting again (S/H can be left on)
The EXEN* signal, controlled by port B bit 0, controls whether an exponential decay exists
on the volume signal (0 to enable decay). This mode is used only in beeps where an
exponential decay is desired. In this mode, the volume signal is enabled only at the start of
the beep and the volume will be allowed to decay by not updating the sample and hold.

Keypad Interface
The keypad interface consists of a matrix of 8 output lines and four input lines. A maximum
of 32 keys can be supported with this arrangement. The 8 output lines, KD.0, are connected
to the upper byte of the data bus. Their address can be set to 740000H for byte access.
The four input lines, KI.0, are also connected to the upper byte of the data bus.
During the scanning of the keypad, a marching 0 is shifted through the 8 normally high
output lines. When a key on the active low output line is pressed, a corresponding 1 (note
inversion) on the normally low input lines would be generated. All key presses need to be
debounced in software.
The keypad interface can be programmed to function in an interrupt driven mode. The KPS*
signal (port B bit 8 line) is active when there are any keys pressed. This is generated by the
use of the PAL, U24. This bit can be programmed to generate an interrupt to the
microcontroller. The operation should be as follows:
• Set all keypad output lines to 0.
• Wait for KPS* to interrupt processor. (Respond before key released, dms)
• Debounce KPS*.
• Scan keypad output lines via marching 0 for key identification.
• Start key time-out for key held down mode.
• After time-out, reset all keypad output lines to 0, clear all pending interrupts and reenable KPS* interrupt. (If key is still pressed, another interrupt will be generated
immediately.)
Recorder Interface
The recorder is a General Scanning AR-42. Detailed programming information is contained
in the AR-42 user’s manual.
The RERR signal is recorder error. It is pulled up (RP3-5) and inverted by U11 to form RERR*.
This signal is then connected to U1-97, which is interrupt 1. Anytime RERR* is active, the
program should service the interrupt and determine what action to take. This can be an error
or this can determine if a recorder is not available. A read of the recorder status lines at
740000H will determine what case it is. The recorder interface is a 16-bit parallel interface
mapped to 760000H. In writing to the recorder, the lower byte contains the data. The lower
5 bits of the upper byte contains the address for combination commands. The recorder can
operate in either a header command/data mode when the address bits are all one’s, or a
combined command/data mode in which the address bits indicate which command is to be
performed. When possible, the combined commands should be used to minimize data
transfer.
In writing to the recorder, the processor should check the SYNC* and WRRDY* lines from
the recorder to make sure that the recorder is ready to accept data.
In reading from the recorder, the lower byte contains readback information from the
recorder.

Block Diagrams
Theory of Operation
There are two operation modes of the recorder: a trace mode and a graphics mode. In the
trace mode, the recorder prints at a fixed rate (e.g. 25mm/sec). And it will request data at its
own rate. If no data is supplied, the previous points will be repeated by the recorder.
Since the recorder needs data at a fairly high rate in trace mode, (up to 800 points per
second), the data rate will be controlled by the CPU. In other words, the CPU will only send
data to the recorder when it so chooses. The recorder will repeat points when it does not
receive data. In trace mode, the CPU should output data to the recorder at the front end
sampling rate: 286Hz.
Due to the relatively slow response time of the recorder (several microseconds), the IDMA
controller can be set up to control the writing of the recorder on a cycle steal basis. The
WRRDY* line is wired to the DREQ* line of the micro-controller. In other words, a DMA cycle
would be requested every time the recorder is ready to accept new data. When the
programmed number of transfers are complete, any further request from DREQ* would be
ignored. Note that the software must keep track of how much actual print data the recorder
can accept in text or graphics mode. This information is contained in the RSYNC* line (buffer
empty). In other words, the recorder interface software can only print on a line by line basis
via DMA.
The RCRST signal is used to reset the recorder. On power-up or reset, the signal would by
default put the recorder in a reset state.
Analog Front End Interface
The analog front end interface is an opto-isolated serial channel with data to and from the
front end processor. It currently runs at 115.2 K baud. This interface is connected to SCC1.
This is done to make the analog front end possess the highest priority interrupt. The CPU can
independently reset the front end processor using the FERST signal (port A bit 11). On powerup or reset, the signal would by default put the front end processor in a reset state.
The analog front end is programmed to transfer a burst of analog data to the CPU at a
sampling rate of 286Hz. This rate is chosen to be a even multiple of the screen waveform
update rate (71.5 samples per second to give 25mm/sec). This sampling rate should be high
enough to capture the details of the ECG waveform.
External RS-232 Interface (optional)
Since the external RS-232 interface connects to external instruments, the communication
features, such as baud rate, parity, etc. are going to be programmable by the user. No CTS
and RTS signals are provided.
Optionally, an RS-485 interface can be installed. (A cut on the board is only necessary to
disconnect the RS-232 receive line.) The differential RS-485 lines are connected via a
bidirectional transceiver as a party line. The receiver is always enabled; the transmitter is
enabled by SEREN (port B pin 7). This line should normally be low to disable the transmitter.
This interface is connected to SCC2.

NIBP Module Interface
The NIBP module interface is also an RS-232 interface, currently running at 2400 baud,
eight data bits and no parity. Only the RxD and TxD data lines are used. This interface is
connected to SCC3. The CPU can independently reset the NIBP module using the NRST
signal (port A bit 7). On power-up or reset, the I/O port is default to input, causing the NRST
signal to be pulled up to reset the NIBP module. There is also a reset acknowledge signal
from the NIBP module that can be read from the recorder status register.
8-bit A/D Converter SCP Interface
The A/D converter is a 12 channel (one is used for internal diagnostic) 8-bit serial A/D
converter. It is connected to the SCP interface on the microcontroller. To initiate a conversion,
the CPU writes the A/D channel address to the upper bits of the SCP transmit buffer. When 8bit that is read back at the same time would contain the result of the previous A/D
conversion. The clock invert bit in the SCP control register needs to be set to 0 to obtain the
proper clock polarity.
The definition of the A/D channels are as follows:

Most of the inputs are used for diagnostic purposes. In diagnostic mode, all the power supply
levels will be read and displayed. In run time, some of these voltages would also be checked
for proper operation (especially +/-15V). The run-time check should be very robust in that it
should not generate false alarms due to noise or other transients (e.g. ESD episodes). A wide
tolerance with probably some form of averaging would be performed.
The raw DC voltage can be checked for whether unit is running on battery (if the voltage is
greater than a certain threshold). When the unit is running on battery, the raw DC voltage
would indicate the battery voltage. A low battery condition exists when the voltage is below
a certain threshold. The proper levels and cutoffs are yet to be defined.
The DAC voltage input can be used to check the operation of the DAC. The ADC diagnostic
voltage can be used to check the operation of the ADC.
The external analog input signal is currently not used.

Timers
Timer 1 is designated as the system timer.
Timer 2 is used to generate the variable tone frequency to the audio circuit. The frequency
ranges from 500Hz to 1500Hz. The operation of the audio circuit should be that when no
tone is desired, timer 2 should be turned off (rather than just setting volume to be zero).
Timer 3 is used as an auxiliary timer.
External Watchdog Timer
An external watchdog timer is implemented with a DS1236, U21. The WDOG* signal is
used to strobe the watchdog (port B bit 3; normally high). The minimum watchdog timer
period is 100 ms. Thus the software needs to force a high to low transition on the WDOG*
line at least every 100 ms. The typical timeout is 400 ms and the maximum is 600 ms.
EEPROM Interface
A serial 1K bit EEPROM, U4, organized as 64 x 16 (ICT93C46) is connected to port A bits
14, 15 and port B bits 5 and 4. The interface signals are data in (EEDI), data out (EEDO),
clock (EESK), and chip select (EECS). All data clocking and shifting will be performed in
software. Consult the 93C46 data sheet for interface information.
RTC Interface
The RTC is a Dallas DS1202, U20. The RTC has a bidirectional data line (EEDI), a clock
(EESK), and a reset (RTC) line. The data line and clock line are shared with the EEPROM
interface (port A bit 14 and port B bit 5). An active high signal RTC (port B bit 10) is used to
enable the RTC for interface. Watch crystal, Y2, is a 32.768KHz clock that is connected to
inputs X1 and X2 of U20. This provides the necessary accuracy for time and date.
SpO2 Interface
A parallel interface similar to the ISA bus is implemented. The parallel interface is only 8 bits
wide. It is attached to the lower byte of the data bus. The 8-bit ISA address space is
1Mword addressable. Thus 2M bytes address space are needed to access this space. This
is mapped into address space starting at 800000H. Currently this parallel interface is only
used to access the SpO2 module. The SpO2 module appears as a block of shared memory
to the CPU. Port B, bit 11 is currently connected to the SpO2 module. Consult the SpO2
module documentation for interface information.
Miscellaneous Inputs and Outputs
Two signals are reserved to drive LED’s: LED0* and LED1* (port A bits 2 and 3). They are
active low. Currently only LED0* is used. It drives the alarm LED.
A defib sync output DSYNC (port A bit 11) is used to provide the external defib sync signal.
This signal should be normally high. The E trigger obtained from the analog front end should
be output to this signal as soon as possible.

Line Battery Board
Overview
The Line/Battery module provides four different power functions.
• Selects “raw” DC power from either an external regulated line supply of 17V, or from two
sealed 12V lead acid batteries. The order of selection is A) 17V external power, B) Two
12V batteries, C) One 12V battery.
• Generates +15V @ 250 mA, -15V @ 250 mA, and +5V @ 1.5A.
• Allows the charging of lead acid batteries to occur.
• Monitors “raw” DC battery power and turns off system when battery voltage drops below
10.5V.
• Provides the battery voltages, the charging voltages and the external +17V for the Battery
Charging LED function on the VGA/EL Panel Board. The Battery Charging LED function
compares the battery voltage to the charging voltage. When the batteries are charging,
no matter what position the power-on switch is in, the green LED is lit.
Once the batteries discharge to a level of approximately 11 volts (for more than 20
seconds), the unit is automatically shut OFF with enough hysteresis that the main power
switch must be cycled to re-initiate a turn-ON. The hysteresis is necessary because when the
system load is removed from the battery, the terminal voltage of the battery will float back up
to the voltage of a charged battery. After the cutoff circuit is activated, a load greater than
100K (@ 12 volts) remains on the battery to avoid excessive discharge and therefore
sulfation of the battery. The low battery cutoff comparator controls a small oscillator that
generates an isolated voltage. This voltage is capacitively coupled via a full wave
rectification circuit. This “floating” supply controls the gate of a very low ON resistance
power FET. This FET controls power to the switching supplies to generate system voltages.

Diode - “OR”
Immediately upon entering this module, the three voltage sources are fused. The 17V line
input is tied to fuse F1 which is rated for 2.5 A and is a slow-blow type fuse. Fuses F3 & F4
are 4 A fuses and are also slow-blow type fuses. The selected fuses are a common 5 X 20
mm size and are approved for both Domestic and International use.This block provides
power entry selection where the line voltage will always be selected before battery power is
selected. The “OR-ing” function is provided by diodes CR8-CR10. These Schottky diodes
are used because of their low forward drop. If the line voltage is available (+17V), CR8 will
forward conduct and CR9 and CR8 will be reversed biased. When line power is removed,
a smooth transition will be made to battery power through CR9 and CR10. The output from
the diode OR (system power) exits this module and returns through the main power switch.
When the system is off, diodes CR11 and CR12 allow a charging path from the battery
charger to each battery. Resistors R10 and R13 provide a path to ground, to bleed
accumulated charge from CR11 and CR12.

Low Voltage Shut Down Comparator / 20 Second Delay Circuit
When the battery drops to 11 volts (10.5 V after the USD945 diode drop and fuse), the low
current comparator will trip. Hysteresis on the comparator circuit will prevent the unit from
turning back ON until the supply reaches 15 V. The purpose of hysteresis is to prevent the
power from toggling ON and OFF when the battery is low and monitor functions are
enabled and disabled.
This circuit employs a low power OP-AMP U1(LM4250) as a voltage comparator. This OPAMP allows the designer to operate the amplifier at a unique operating point established by
R6. In this application, R6 biases the comparator at 1Ua. This equates to approximately
10Ua of supply current drain at 10V. Another low power device, the LT1004-1.2 (CR1) is a
zener diode used to develop a precision voltage reference at the negative terminal of the
comparator. This device is specified to “zener” at 1.2V with only 10Ua of current. The
10Ua zener current is provided by R3. A precision resistor divider consisting of R1, R2, and
R4 apply the appropriate voltage to the positive input terminal of the comparator. If the
supply voltage is greater than 10.5 V, the divider voltage will be greater than the reference,
and the output will jump towards the positive rail. When this occurs, CR2 will forward
conduct causing the combination of U2C and U2A to turn Q1 (2N7000) “ON” In turn, Q2
(2N7000) will be forced OFF to eliminate R4 from altering the divider circuit. This state is
the normal state for proper operation. However, if the supply dips below 10.5 V , the
following events happen.
The positive input to the comparator will be less than the reference. This will cause the
comparator output to jump towards the negative rail. When this occurs, CR2 will reverse
bias and the rail voltage on C7 will discharge through R12. If the supply does not rise above
10.5 V in a period of time greater than approximately 15 seconds (exponential decay of C7
and R12 to the trip point of U2C) Q1 2N7000 will turn OFF. Q2 the 2N7000 transistor will
now turn ON causing R4 to modify the resistor divider and force the divider input voltage to
fall further below the reference. The circuit will remain in this state until the power switch is
toggled or the supply voltage exceeds 15 V.
Turn On:
Capacitor C1 and R8 forces Q1 to turn “ON” and Q2 to turn “OFF” during power-up. This
is to insure that the hysteresis resistor R4 will not be connected during power up, to establish
the proper state for normal operation.

Oscillator / Charge Pump Circuit
An oscillator is formed from the R11 - C4 combination around U2 (CD4093 Schmitt trigger
nand gate). The second input to the Nand gate from the comparator circuit provides an ON/
OFF switch to the oscillator. This oscillator, at a frequency of 200 KHz, is tied to another
Schmitt trigger to form complementary outputs. The two output signals are coupled to the
system power (FET) switch “ gate” through a pair of .01Uf capacitors (C5 and C6) and a
bridge rectifier (CR3-CR6) that converts ac voltage to dc. This circuit forms an approximate
voltage doubler. Therefore at a cutoff supply voltage of about 9.5V, this circuit will provide
9.5 volts at the gate of this FET. This FET needs a Gate to Source voltage of 5V at a Drain
current of 4A (the system only requires 1A), providing a safety factor of almost two.
CR7 clamps the input to U2 from going higher than the supply rail. This component offers
protection to the IC U2. R9 bleeds charge off of capacitors C5 and C6 to shut off the FET
when the oscillator is disabled. R14 limits current to the FET gate when the FET is initially
turned “ON”.

Detail
This flyback converter runs at 100 KHz and generates +12 volts (to power loads with large
step load changes) and -23.5 volts (a low current supply for the display). A 2843 PWM (U1)
drives a power fet (Q1) which switches the primary of the flyback transformer (T1). C9 and
C10 are low esr aluminum electrolytics which provide the instantaneous pulsitile power
required locally by the input of the converter. L1, L2 and C8 filter converter high frequency
(100 KHz) noise from the input power line. CR1,C11 and R10 snub energy stored in the
primary leakage inductance of T1. L5 and L6 are lossy ferites which damp high frequency
(10’s of MHz) oscillations in the primary switching loop. CR6 does not function in normal
coarse of operation of the converter, but clamps voltage spikes which might occur at the
drain of Q1 for short circuit conditions of the converter’s main output. Likewise, CR5 does not
function in the course of normal operation, but clamps any abnormal voltage spikes which
might couple thru Q1’s drain gate capacitance. CR4 decouples Q1’s gate from the
capacitance of CR5 so as not to slow down the switching time of the fet. R9 keeps the fet
turned off for times when U1-6 is not active. C18 and R8 provide a high speed, yet damped,
switching path between U1-6 and the gate of Q1. R3 and R4 form a feedback voltage
divider from the 12 volt output back to the inverting input (U1-2) of the error amp in the pwm.
R5, C14, and C13 provide compensation for the voltage feedback loop. C12 and C16
locally decouple Vcc and Vref of the pwm respectively. R6 and C15 are the timing
components for the internal oscillator of the pwm. T2 provides primary current mode
feedback to the pwm. The positive going current ramps are passed by CR2 and scaled by T2
and R7 to give a corresponding voltage waveform of roughly .12 volts / amp in the primary.
C17 filters leading edge spikes from the reconstructed current waveform due primarily to
discharge of Q1’s drain capacitance. CR3 allows enough voltage backswng to reset T2’s
core and yet clamps the voltage so as not to destroy Q1.

On the secondary side, CR9 and C1 and C2 rectify and filter the 12 volt output. Likewise
CR10 and C3 rectify and filter the -23.5 volt output. L3, L4 and C4 provide additional
filtering. R1 and C5 damp energy in the 12 volt secondary leakage inductance. Likewise R2
and C6 damp energy in the -23.5 volt secondary leakage inductance. U3, R12 and R13
make up a linear regulator for the -23.5 volt output (input to the regulator is typically about 3
volts higher than the output). Q3, R14, Q4, R16 and R15 are used to gate power into the
linear regulator via a 5 volt logic control signal.
R11 senses the current in the 12 volt secondary. R17,C19,R8,R19, and C20 filter this signal
prior to sense by comparitor U2B. The 5 volt reference of U1, R8 and R19 offset the input of
the comparitor such that it will trip at approx. 1.9 amps. CR8 and C21 add hystersis and a
“hiccup” time constant to the comparitor. U2A buffers the output of U2B prior to resetting the
soft start circuit R24 and C23. Q2 functions as a follower which buffers the soft start RC prior
to pulling down the output of the pwm error amp (U1-1).

Planar EL Panel Board
Overview
The panel board locates physically the visible indicators in reference to the front panel of the
monitor. It contains the LED driving circuits and buffers for the EL data lines. Due to its
location in the assembly, it provides convenient means for interconnection between the CPU
board, the EL panel, the DC/DC converter, the front panel keyboard, and the speaker.
Functional Description
The LEDs provide two indicating functions: power on - green, alarm on - red.
When activated, the alarm LED is flashing at a 3 Hz rate and 50% duty cycle. The speaker
produces all the required tones (i.e. heart rate beeps, alarm and alert tones). The alarm LED
control and the speaker signals are generated on the CPU board.
A 40 lead ribbon cable from the CPU brings the required voltages and logic signals for the
EL panel, the indicators and the keyboard. Four lines control and provide data for the EL
panel. Eight output and four input lines interconnect the 8 by 4 keyboard matrix. Detailed
description of the signals and power leads is given in Chapter 3 on page 3. The DC/DC
converter generates the power for the EL panel.

CO2 Interface Module
The CO2 Interface Module, or CIM, provides the electrical interface between the Passport
monitor and the Novametrics CO2 Control Modules. Some CO2 Interface Modules support
Mainstream CO2 monitoring only while others support Sidestream and Mainstream CO2
monitoring. The CIM provides both buffered data communications as well as power supplies
for the Capnostat.
FIGURE 2-25 CO2 Interface Module Block Diagram
Overview
An overall block diagram of the CIM is shown in figure. Bus interface logic, consisting of a
programmable logic device, an octal register, and an octal buffer, connects to the Passport’s
pseudo-ISA bus. This bus is shared with the SpO2 module. Therefore, bus resources have
been allocated to avoid conflicts. This interface logic implements two read-write registers,
one for data and the other for control or status. A microcontroller, type 68HC705, operates
as an intelligent, highly buffered UART. The serial port of the microcontroller provides the
data interface to the Mainstream and Sidestream CO2 control modules. The Mainstream
CO2 requires 5 volt and dual 15 volt power for operation. The Sidestream CO2 requires 5
volt and dual 12 volt power supplies for operation. The 5 volt power is supplied directly from
the pseudo-ISA connector. However, the dual 15 volt and 12 volt requirements exceed the
capabilities of the Passport power converter, due to the presence of large pulsations in load
current. Therefore, the CIM contains an additional DC-DC converter to supply these
requirements from the bulk supply. A filter is used to assist in handling the pulsatile load
component. Due to even more stringent power supply requirements, the Sidestream CO2
control module requires an additional cleaner -12 volt supply (-12V capnostat on the block
diagram).

Theory of Operation
Microcontroller
The microcontroller manages the flow of data between the host and the Novametrics
Capnostat. It consists of a 68HC705 OTP single chip microcontroller. It operates at an
oscillator frequency of 3.6864 MHz, obtained from the network including crystal Y1, bias
resistor R1, and loading capacitors C1 and C2. The oscillator also provides clocking for U4.
When it is brought out of reset, an internal self test is performed, which verifies the PROM
contents and RAM operation. During this self test period, lasting several ms, bit 4 of port C is
configured as an output and driven low. This asserts reset to the Capnostat. At the conclusion
of the self test, this pin is reconfigured as an input, releasing the Capnostat reset, which is
designed for an open-collector interface. The start-up of the Capnostat and CIM are thus
synchronized.
Any data written to the CIM data port is accepted by the microcontroller on port B. Data to
be sent to the host is asserted on port A. Communications with the Capnostat take place by a
CMOS level asynchronous serial link in J92. The parameters are 9600 baud, 8 data bits, no
parity, and one stop bit, with the data having “true” polarity.
Two locations for optional jumper links are provided. They can be read on bits 6 and 7 of
port C. Jumper JP2 is reserved for future options. If JP1 is present a special test code is
invoked immediately after reset.
Power Converter
The CIM also supplies operating power to the Capnostat. Power connections are made via
J92 and J94. The +5 volts and digital ground obtained from the ISA bus are used to supply
logic power. The +5 rail used to power the Capnostat II through a dropping resistor R2, also
powers a heater in the Capnostat. The Capnostat II and III also requires dual 15 volt and 12
volt supplies respectively. However, it draws large transient currents from these rails, making
it undesirable to operate the Capnostat from the host’s 15 volt analog supplies. Therefore, the
CIM includes a commercial DC-DC converter module, VC1, which supplies these
requirements. The converter is powered from the raw bulk supply, obtained from J93.
Capacitor C10 reduces the reflected load transients. A converter capable of supplying the
peak Capnostat load currents would be quite large. For this reason, the converter is sized
closer to the average requirements, with a filter consisting of C9 and L2 providing smoothing
of these peaks. The Capnostat III also requires a -12V linear supply. This is derived from a 12V regulator, U5.
Interface Connectors
The CIM is capable of interfacing to either a Capnostat II or III. Unfortunately, the 2 modules’
interface connector have different signal definitions. In order to prevent the possibility of the
wrong module being plugged into the CIM, 2 connectors were specified. One is for the
Capnostat II (J92) and one is for the Capnostat III (J94). They differ in that the Capnostat II
uses a 15 V supply and also has a separate 5V heater supply, while the Capnostat III uses a
dual 12V supplies.

Board 0670-00-0375
FIGURE 2-26 NIBP Module Block Diagram
Overview
The NIBP module consists of two boards interconnected by a 20 pin cable: the control board
that contains most of the electronic circuitry ; and a pneumatic board that contains all the
pneumatic parts.
The CPU
The electronics are built around a 16 bit microcontroller (80C196). Built into the 80C196, in
an 8-channel 10-bit A/D converter, five 8-bit I/O ports, pulse width modulators, high-speed
inputs and outputs, an UART, a watchdog timer, and two 16-bit counter/timer.
An 11.0592MHz crystal is connected to the on-chip oscillator of the 80C196. This
frequency is chosen for accurate generation of standard baud rates (the on-chip UART has an
integral baud rate generator). An RC circuit, R1 and C1, resets the 80C196 on power-up.
The microcontroller can also be reset from an external, open-collector, active low reset signal
from Pin 8 of connecter J28.
The non-maskable interrupt, NMI, of the 80C196 is used to detect the overpressure (OVPR)
condition. A low to high transition on the OVPR signal will cause the microcontroller to sense
the overpressure condition. The OVPR signal is also connected to the high speed input bit 1
of the microcontroller for it to verify the overpressure condition.
The BUSWIDTH input is tied low since the eight bit data bus mode is used for external
memory access. The EA/ pin is tied low since external EPROM and static RAM are used for
program and data memory.

Theory of Operation
Address Decoder
The 80C196 address decoding is controlled by an EP320 EPLD (U7). Two different decoding
is possible, depending on the state of the signal PIB (OPT2). In the module mode, PIB is high.
In the module mode, (module mode = DSBP module used in any product other than
ACCUTORR 3/4) when the bank bit BANK, (U5 pin 33) is set high, the lower 32K bytes (032K) are mapped to the on-board EPROM; the next 8K bytes (32K-40K) are mapped to nonvolatile RAM; the next 16K bytes (40K-56K) are not used; and the last 8K bytes (56K-64K)
are mapped to I/O, the only I/O available being the quad DAC, U9.
When the bank bit is set low, the lower 8K bytes (0K-8K) are still mapped to the on-board
EPROM; but the next 24K (8K-32K) bytes are mapped to nonvolatile RAM; the remaining
RAM and I/O space remain the same.
The address decoder EPLD, U7 also disables the pump when the overpressure condition
OVPR is set and buffers the reset signal to the 80C196 microcontroller.
The Pressure and Pulse Channel Amplifiers
The normal pressure transducer installed is a Sensym BP01. The output of the pressure
transducer is amplified by an instrumental amplifier implemented by U13A, C, and D. The
gain can be adjusted by trimpot VR1. The output is then buffered, low pass filtered and offset
adjusted by U13B and sent to the 80C196 A/D channel 7 at the pressure signal. The offset
is automatically corrected by adjusting the voltage level of OFFSET from the output channel 1
of the quad DAC U9. The gain of the amplifier is such that the output at U13 pin 7 is about
68.27mmHg/V.
The pulse channel signal is obtained by AC coupling and amplifying the pressure signal
(U13B-7). The pulse channel output can be reset by activating the CLEAR signal. This signal
can be activated when there is disturbance at the pulse output during pneumatic switch-overs
or severe motion artifacts. There are two gain switches controlled by U8A and U8B,
implementing four possible gain settings. The nominal gain settings for the pulse channel are
about 28, 56, 111, or 222. The default gain for adult mode is 28 and the default gain for
neonate mode is 111. The pulse signal is connected to the 80C196 A/D channel 5.
U11, U21B and U21C are not used at this time.
Reference voltages +5VR and -5VR are generating by amplifying a 2.5V reference generator
U12 by a factor of 2 and -2 respectively.
The sampling rate of the 80C196 A/D is about 250 Hz.

Pneumatic and Miscellaneous Control
The five MSB’s of I/O port 1 of the 80C196 are used to control the air valves. All the valves
are of the normally open type. In case of loss of power, the valves will open VALVE0 is the
dump valve, which lets air out of the cuff when the measurement is complete. VALVE1,
VALVE2, VALVE3, and an optional VALVE4 controls valves that have different orifice
openings. They are used to control the bleed rate of the pressure in the cuff during a
measurement. The valve control signals are buffered by U15, an ULN2003. U21D
implements an optional linear valve driver that is driven by channel A of U9, the AD7226
quad DAC. It is currently not used.
The pump is controlled by a pulse width modulated output from bit 1 of the high speed out
put section of the 80C196 (U5 pin 29). In adult mode, the pump runs at full speed; in
neonate mode, the pump is pulse width modulated to moderate the pump speed. The pump
signal is active high and the high speed outputs reset to a zero state. On power-up, the pump
is turned off.
An overpressure switch will close when the pressure in the cuff is 375 mmHg +/-5%. This will
set the latch implemented by U17A and U17B which cause the OVPR signal to go high. This,
in turn, will force VALVE 0 to open and the pump to stop. This condition can only be reset by
resetting the entire module. This is done by power-cycling the unit.
Pneumatic and Miscellaneous Control - Linear Bleed
The pneumatics board consists of two valves, and EMI filter and connector for a chassis
mounted pump, an overpressure transducer and detection scheme, and control logic to
operate the linear bleed system. The pump is used to inflate the cuff at the beginning of each
measurement cycle. Inflation pressure is regulated by software monitoring a pressure
transducer located on the companion control board. In the event of a runaway condition of
the pump, the patient size sensitive overpressure circuitry will completely open the linear
valve and close the dump valve, fully venting the cuff while at the same time blocking the
pump from further inflating the manifold. At the onset of the actual measurement phase, the
bleed valve (V2) opens to provide a gradual reduction of the cuff pressure. This is a so-called
proportional solenoid valve. Rather than providing only “on-off” control, it can be opened to
a variable degree, in proportion to the current flowing in the valve coil. Note that this valve is
a normally closed type; coil current must be supplied to cause the valve to open. A servo
control loop maintains the pressure bleed down rate at a nominal 6 mmHg per second,
regardless of the cuff pressure or system volume. During the measurement phase, the
pressure signal acquired by the transducer on the control board is processed to extract the
oscillometric blood pressure data. At the conclusion of the measurement phase, the dump
valve (V1) is opened, in addition to the bleed valve, to rapidly exhaust the residual cuff
pressure.
The pump control is provided by the MOTOR signal, generated on the companion control
board and routed to the pneumatic board through connector J30. Power to the motor is
supplied by means of a decoupling network L2/C12 from the host’s +12 volt bus. A common
mode coil, L1, provides further attenuation of the motor brush noise.

Block Diagrams
Theory of Operation
The dump valve is controlled by the DVEN signal. This signal drives MOSFET Q1, which
switches the valve coil voltage. This is a normally vented valve, meaning that air flow occurs
from the manifold to the atmosphere while blocking the pump when the coil is de-energized.
This corresponds to a logic low on the DVEN signal. Should an overpressure condition occur,
the valve defaults to the vented state. The DVEN signal is gated in U3 to protect against a
single fault failure which would cause the dump valve to remain in the energized (non-vented)
state. In order for the dump valve to be energized, two dump valve enable signals must
agree. One signal is generated by the microprocessor on the companion control board, and
the other from microcontroller U1 on the pneumatics board.
The overpressure circuitry identifies two separate patient types; adult and neonatal. The
neonatal mode is inferred from the existing conditions during pump-up. If the motor is running
and a valve is open, then the neonatal mode is identified and NEO is set low by U1. The
over pressure comparator in U6 compares the output of the overpressure transducer with the
output of a voltage divider. If the pressure transducer voltage is higher than the output of the
voltage divider, OPS is brought low. A single overpressure trip point can be exactly
calibrated by adjusting potentiometer R1, presumably the neonatal point. This reduces any
error caused by resistor tolerances and inexact transducer readings. NEO is compared to a
threshold by a second comparator in U6, and if low, resisterR15 is shunted across resistor
R25. This reduces the effective resistance in the grounded resistor in the voltage divider,
causing a lower overpressure trip point in the neonatal mode.

FIGURE 2-28 Panel Board Block Diagram
Overview
The Front Panel Board contains a frame buffer converter that takes a video data stream
formatted as 640x240 at 60Hz and converts it to a 640x480 format at 120Hz. The single
video bit stream is also converted to a dual scan LCD type 8-bit parallel interface required by
the EL panel. Appropriate timing signals are also generated to control the EL panel.
An optional alternate interface circuit is included to drive an alternate color LCD panel. Three
color signals (RGB) at 640x240 format at 60Hz and I signal are double scanned using a
video line buffer memory to drive the color LCD panel with a 640x480 format at 60Hz.
Monochrome EL Interface
The monochrome EL panel interface (0670-00-0617-03) consists of two control EPLD’s
(U1,U2) and a dual-port VRAM. The two EPLD’s in essence perform the functions of a simple
video display controller. The input video data is written into the video memory; the output
video data is simultaneously accessed and sent to the EL panel.
The parallel access port of the VRAM is used to write the input video data into memory. As
such, the parallel data port is used only in the write mode. On the other hand, the serial
access port is used only in the read mode to access the video output data. To simplify the
video output logic and timing, the input video data is formatted appropriately before it is
written into the VRAM, while the output video data is clocked directly from the VRAM to the
EL panel.

Theory of Operation
Only 640x240 bits of memory storage is required, so very little of the much larger available
VRAM is actually used. Refresh of the memory that is being used is automatically performed
as the video data is constantly being written to.
The VRAM parallel access address is controlled by the input horizontal and vertical video
counters. The horizontal counter counts the 912 columns of the display format (640 of which
are displayed data, the remaining columns are used for horizontal retrace). The horizontal
counter is used to drive the column address of the VRAM. The horizontal counter is clocked
by the video dot clock VCLK/ and cleared by the rising edge of the input horizontal sync
signal.
Since the 8-bit input data is formatted as 4 bits for the upper split screen and 4 bits for the
lower split screen, only 4 bits of input video data is written to the VRAM in each access.
Since the video data is written in 4-bit chunks, the lower two bits of the horizontal counter is
not sent to the VRAM address.
Depending on whether the input video data is from the top 120 lines or the bottom 120 lines,
the input video data is written to the lower 4 bits or the upper 4 bits of the 8-bit VRAM input
data path respectively. Since the input video format is single bit serial, a 4-bit shift register is
used to convert the input video data to a 4-bit parallel format. An 8-bit multiplexer directs the
4-bit shift register (double-buffered to accommodate the VRAM timing) to the appropriate half
of the VRAM parallel data input.
The write-per-bit feature of the VRAM is used to mask the appropriate 4-bits of the VRAM
parallel data input such that only the corresponding 4-bits of video information is being
written. A mask of either 00001111 or 11110000 is used depending on whether the input
video data is from the upper screen or the lower screen. The mask is written to the VRAM on
the following edge of RAS/ during the block write cycle. This mask data is selected by the
same 8-bit multiplexer that controls the VRAM parallel input data.
Since the VRAM may not necessarily power up in the correct mask mode, a CBR (CAS/
before RAS/) refresh cycle needs to be performed periodically to reset the VRAM in the
default masking mode (new mask mode) for the mask data to work properly. This is done at
the beginning of every input horizontal scan line. If a output start line address clock cycle is
not needed, then a CBR cycle is initiated in its place, before the pixel data of the horizontal
scan line is written into the VRAM.
The lower 3 bits of the horizontal counter actually forms a state machine that controls the
VRAM memory cycles. The first 3 states (S0,S1, and S2) are used to strobe in the
appropriate row address of the output video stream when the need arises (the data transfer
signal DT/ and the write control signal WB/ are changed accordingly). The last 5 states are
used to write two 4-bit chunks of input video data into the VRAM.

Passport 5-Lead, 5L, LT, XG Service Manual
Theory of Operation
Block Diagrams
The vertical video counter is used to count the 262 rows of the display format (240 of which
are displayed, the remaining are used for vertical retrace.) The vertical video counter is
clocked by the rising edge of the input horizontal sync and cleared by the input vertical sync
signal. The vertical video counter wraps at count 120, which demarcates the upper and
lower halves of the screen. This is used to toggle the signal TOP/, which indicates which half
of the screen the video data is in. The vertical counter is used to drive the row address of the
VRAM.
Because of the timing requirements of the EL panel, the vertical line timing of the output video
need to be different than the input line timing. To accommodate this, a separate horizontal
and vertical output counters are used to determine when the appropriate row address should
be strobed into the VRAM to initiate another row of output video data. After this row address
is strobed in the VRAM by the RAS/ signal, the CAS/ signal strobe in the column start tap
point, which, in this case, is always zero. An address multiplexer is used to select the
appropriate input and output row and column counters respectively.
The EL panel timing is such that the input video clock of 14.318MHz is divided by 2.5 to
generate the output video clock. A new vertical sync is generated at 120Hz, as well as a
new horizontal sync.
EL and Color LCD Interface
The EL and Color LCD Panel Boards (670-00-0617-XX) has a built-in frame buffer and the
interface is regular timing at a 60Hz rate. Therefore, the interface requirements are much
simpler. All that is necessary is each input horizontal scan line needs to be doubled to
convert the 640x240 input format to the 640x480 output format.
A 910x8 bit video line memory buffer is used to temporarily store each incoming video line
and clocked out twice as fast to double the video line. The input video clock of 14.318MHz
is doubled by a clock doubler circuit. The input horizontal sync signal is doubled simply by
feeding it to the video line buffer and clocking out twice as fast. The RGBI input color video
signals are also fed directly into the video line buffer and clocked out twice as fast directly to
the EL or LCD panel.
The main function of the PAL is to fit the 912 input columns into the 910 bit video line buffer
by effectively deleting two input clock cycles. It also generates miscellaneous control signals
required by the video line buffer.
Battery Charging LED
The EL or Color LCD Panel Board controls the Battery Charging LED (Color: Green). The LED
is lit when the batteries are charging no matter what position the power switch on the
Passport is in. Two comparators are use to compare the Battery Charging voltage to the
Battery voltage. When the charging voltage is greater than the battery voltage, the output of
the comparators is low which turns on the LED. The function is powered by an external +17 V
which improves the internal power management and allows the system only to work when
the external power supply is plugged in.

Alarm LED
The Alarm LED is a high intensity red LED. It is driven by a FET, a 2N7000 which is controlled
by the signal LED0 from the CPU.
Speaker Interconnections
The EL/LCD Panel Board provides connection from the CPU board to the speakers.
Keyboard Interconnections
The four input lines KI0 through KI3 and the eight output lines KD0 through KD7 provide
interconnection between the CPU board and the 8 by 4 matrix keyboard. A jumper on line
KI3 to KD3 and KD4 is used to indicate which display is being used.
DC/DC Converter
The power supply on the Panel Board is a DC/DC converter. The input voltages to the power
supply is from the Line Battery Board which improves the power management of the system.
The input voltage range for the DC/DC converter is 9 to 18 Volts. The power supply provides
a +12V @ 1.250 Amps Max. for the monochrome EL display.

Termination Board
Overview
The Termination Board’s function is to help reduce emissions from high speed EL/LCD display
signal outputs and 5 VDC power from the CPU board (P/N 0670-00-0651) in the Passport.
The Termination board is inserted between the output connector J68 on the CPU board and
the ribbon cable (P/N 0012-00-0744) that connects to the EL/LCD Panel board (P/N 067000-0617).
Common Mode Choke
The common mode choke is a ferrite device that reduces conducted emissions on signal or
power lines without affecting transmission. The ferrite acts as an attenuator to high frequency
signals by absorbing extraneous and unwanted energy. Low frequency and DC signals see
only the conductor and are unimpeded without any loss. High frequency signals encounter
inductive resistance due to the ferrite providing the insertion loss for dissipating EMI. Since
this choke is common mode it attenuates unwanted common signals on both the power and
digital ground.

Termination Resistors
Series 75 ohm termination resistors were inserted on the nine highest frequency EL/LCD
data, clock and sync signals. This was necessary because these signals are generated from
high speed CMOS logic devices whose outputs are under damped and ring. This is shown

Introduction
This chapter of the Service Manual provides the necessary technical information to perform
repairs to the instrument. The most important prerequisites for effective troubleshooting are a
thorough understanding of the instrument functions, as well as an understanding of the theory
of operation. Therefore, if necessary, refer to the Operating Instructions (P/N 0070-00-0324
for 5L units or P/N 0070-00-0397 for XG units) which describes the instrument functions and
features, and refer to Chapter 2 of this manual which provides a theory of operation.
4.2
Safety Precautions
In the event that the instrument covers are removed, observe the following warnings and
general guidelines.
A. Do not short component leads together.
B. The troubleshooting charts are not intended as a rapid course on how to repair devices
of this type. Rather, they are intended as a guide for qualified technical personnel only.
The instrument covers must not be removed by other than technically qualified personnel
who have received supplementary instructions regarding maintenance of medical
electronic equipment or have has equivalent experience in this area.

Troubleshooting Guidelines
In an instrument as complex as this, it is virtually impossible to list each and every potential
problem and appropriate action. Any given problem, however, can be effectively identified
through an understanding of the instrument features and the theory of operation. These are
prerequisites for repair. If necessary, read the Operating Instructions Manual and study the
theory of operation presented in Chapter 2.0 of this manual. The time spent reading and
absorbing this information is generally realized by a reduction in repair time and, ultimately,
in the overall experience of service personnel.
NOTE:
The numbers in parentheses () refer to the isometric
drawings.
General Troubleshooting Guidelines
1. Identify The Problem. Due to the wide ranges of potential symptoms, certain
problems may be more subtle than others. One approach to trouble-shooting is to set-up
the instrument for testing as described in Chapter 7 and attempt testing. If successful,
there is a reasonable assurance that there is no problem. By contrast, the fact that a
particular test is not successful is generally indicative of a failure in that specific area.
The cause of the symptom can now be further isolated by referring to Chapter 2. Section
2-5 contains a listing of specific circuits or areas in the instrument, each of which is
dedicated to provide a specific function. Once the operation of that circuit is
understood, trouble-shooting can be completed by making measurements in that circuit
to determine which component(s) is at fault.
2. Avoid Shorting Component Leads. During repair procedures, it can become
tempting to make a series of quick measurements. Always turn off the power before
connecting and disconnecting test leads and probes. The accidental shorting of
component leads can easily over stress components, resulting in a second unnecessary
failure (aside from creating a possible safety risk).
3. Use The Proper Equipment. This equipment listed in “Equipment and Special Tools
Required” on page 4-3 is suggested to fulfill a wide range of troubleshooting
requirements. Use a soldering iron the appropriate wattage for a given job. For
example, use a pencil-type iron (25 watts max.) for repairs to printed wiring boards and
a pistol-grip (75 watts) for repairs requiring this much power. Do not use the high
powered iron to repair the printed wiring boards as the conductors will lift from the
board under the extreme heat, thus ruining it.
4. Clean The Repair Area. After soldering operations, clean off the repaired area with
alcohol and a stiff hair brush. This will remove residual solder flux, making the repaired
area more visible for inspection and returning the instrument to its original, neat
appearance. Removal of the flux will also facilitate making electrical measurements in
the affected area.
Exchange Program
Datascope offers an exchange program for certain assemblies in the instrument. In many
cases, replacement of the complete assembly will result in the most expedient repairs. See
“Exchange Program” on page 6-2 for details concerning the exchange program.

E.
Removal / Installation of the Passport XG Color LCD Backlight Tube
WARNING:
The following precautions should be observed before
replacing the backlight:
1. Replacement of the backlight involves the handling of High Voltage circuits. If
replacement was done incorrectly, the display could present a shock, fire, or other
hazard, both during and after the replacement procedure. Make certain that the
Passport is turned OFF, the external power supply is disconnected, and all
batteries have been removed. Also, since the High Voltage power supply can hold
a charge, be sure to wait some time after switching the power OFF before starting
any work.
2. Since the backlight tube and the High Voltage power supply can be HOT after
use, there is a danger of injury by burning. Therefore, be sure to wait some time
after switching the power OFF before starting any work.
3. The fluorescent lamp of the backlight is glass and may in some cases be
damaged. Take adequate care not to injure yourself while doing this procedure.
Moreover, if the lamp is damaged inside, apart from safety considerations,
quality problems may occur, such as uneven brightness from pieces of broken
glass left inside the display. In this case we recommend that you return the unit to
Datascope for repair.
4. Since the backlight uses a cold cathode fluorescent lamp, dispose of it in
accordance with the regulations in effect in your area.
5. Since the display can be easily damaged, take care not to scratch, mar, chip,
etc., the front surface.
6. Static electricity (ESD) can damage the display. When handling the display take
adequate precautions to eliminate static electricity (grounded wrist strap, ionized
air blower, conductive mat on work surface, etc.).
7. Do NOT touch the reflective surfaces inside the backlight holder, or the fluorescent
lamp, or any connector contacts with your bare hands. Oil and other
contaminants on your hands can damage these surfaces and contacts.

8. To prevent the optical surfaces from attracting dust, dirt, and scratches, we
recommend that the backlight replacement be performed in a dust free
environment.
9. Customers replacing the backlight do so at their own risk. Datascope will not
assume any liability, and will not warrant any displays which have been modified
by the customer, including replacement of the backlight, even when the following
procedure is used and all of the necessary precautions have been taken.
Replacing the backlight can cause a lowering of the quality (performance). Even if
the replacement work is performed in accordance with the following procedure,
Datascope can not guarantee the resulting quality.
1. Perform the steps outlined in “Removal of the Passport XG LCD Color Display” on
page 4-4.
2. Taking care not to scratch the front of the display, place it face down on the flat static
free work surface.
3. Looking at the back of the display, locate the metal backlight holder by following the
high voltage wires to the side of the backlight tube.
4. Using round tipped tweezers, or an equivalent tool, release the backlight holder by
carefully pressing down on the small plastic tab that latches it in place. See Figure 1,
Detail “A” Side View.
5. Slowly, gently, and in a straight line pull the backlight and holder out of the side of the
display. If the fluorescent lamp was broken inside the display, carefully pull out the
backlight. If pieces of the glass remain inside the display, carefully remove them.
6. Once the old backlight and holder have been removed, slowly, gently, and in a straight
line push in the new backlight (P/N 0149-00-0009) until the small plastic tab latches it
in place.
7. Reassembly of the display into the Passport is the reverse of the disassembly.

Introduction
This chapter of the Service Manual provides information necessary to identify the
replacement parts and assemblies of the instrument.
6.2
Available Replacement Parts and Sub-Assemblies
The parts listings which follow are divided into two sections. The Isometric Drawings and the
accompanying parts lists identify the available chassis mounted components. A listing for the
components on each circuit board then follows.
6.3
Product Variations and Options
Product variations, due to differences for various line voltages, may require different
components. These variations are reflected, where necessary, on the parts lists.

Exchange Program
6.4
Replacement Parts
Exchange Program
Datascope offers an exchange policy for most of the printed circuit board assemblies. This
program may provide the most expedient method of servicing the equipment. A standard
charge for this service is made. Contact the Datascope Service Department for details
concerning this exchange program.
Many circuit boards make extensive use of multilayer technology and high density
packaging. Individual component replacement is not recommended on these boards unless
the technician is properly equipped to repair multilayer circuit boards.
Circuit boards, returned as parts of the exchange program, that show evidence of improper
repair techniques and are damaged in the process are not considered for exchange.
Damaged boards will be invoiced at full value and no exchange credit will be applied.
6.5
Replacement Parts Pricing Information
Current parts prices and exchange charges can be determined by contacting Datascope,
Order Entry Department.
6.6
Ordering Information
Replacement parts and assemblies are available from Datascope Corp., and in Europe from
Datascope B.V. Please follow these guidelines when ordering replacement items for the
instrument.
1. Include the Model and Serial Number of the instrument.
2. Include the Datascope Part Number exactly as it appears in the Parts List under the

Ordering Information
Many components are described with sufficient detail to permit procurement through local
commercial channels. This applies to hardware, such as screws and fasteners, as well as to
certain electronic components, such as resistors, capacitors, certain integrated circuits and
transistors. However, in some cases, components are selected by Datascope to meet special
performance criteria above and beyond the component manufactures specifications. This
may apply to solid state components, relays and batteries. The use of other than Datascope
components in these applications may result in degradation of reliability or instrument
performance characteristics.

Calibration
Introduction
The following procedures are provided to verify the proper operation of the Passport 5 Lead/
5L/LT Monitor. Service diagnostics provide the capabilities of diagnosing problems in the
Passport hardware in the field. A menu driven interface, with the same “look and feel” as
that of the online Passport user interface, is used to execute all tests. The Diagnostic Menu
Tree (located on page 7-3) is provided for reference once familiar with these procedures.
7.2
Warnings and Guidelines
In the event that the instrument covers are removed, observe these following warnings and
general guidelines:
• Do not short component leads together.
• Perform all steps in the exact order given.
• Use extreme care when reaching inside the opened instrument. Do not contact exposed
metal parts which may become live.
• Read through each step in the procedure so it is understood prior to beginning the step.

Mainstream CO2 Adapter Calibration
Adapter calibration compensates for the optical differences between the adult and neonatal
airway adapters for mainstream CO2 operation.
Adapter calibration needs to be performed each time the type of airway adapter is switched.
For example: if switching from using a re-usable adult to a neonatal or neonatal to a reusable adult adapter, a calibration is needed (not if switching from a re-usable adult adapter
to another re-usable adult adapter). Adapter calibration should also be performed if the
message “Check Adapter” displays.
NOTE:
In order to perform an accurate adapter calibration, the
“Sensor Warming Up” message must not be displayed.
To perform an adapter calibration:
1. Place the sensor and airway adapter away from all sources of CO2 (including the
patient’s and your own exhaled breath, and ventilator exhaust valves).
2. Choose Start Adapter Cal - Yes from the CO2 menu. (See “Use of Menus” on
page 109.)
NOTE:

Leakage Current Test
NOTE:
7 - 30
The Passport Monitor is not considered double insulated
because it has provisions for grounding via the three
conductor line cord to U-blade ground through the external
supply. The external supply is considered a recognized/
certified component by the UL/CSA and is part of the
monitor. However, the monitor does not have any accessible
exposed conductive metal. The U-blade connection is not
carried through the external supply into the monitor itself,
the DC voltage is only provided. NFPA 99 section 7-5.1.3.2
does not apply because no metal on the monitor can
become line energized. The Passport was evaluated with
the external supply by UL and CSA with no grounding
impedance verification. If you check U-blade resistance, the
safety analyzer will read “open”.

Sterilization and Cleaning of Reusable Cuffs
Remove the latex bag from the cuff. The cuff and latex inflation bags may be cleaned with an
alcohol wipe, a disinfectant wipe, or by sponging with a damp cloth. Both may be sterilized
with commercially available disinfectant soaks.
CAUTION:
Using dark colored soaks may stain the cuffs. Test a single
cuff to ensure that no damage will occur. ETO sterilization
may also be used.
Hand washing will enhance the service life of the cuff. Remove the latex bag and hand wash
the cuff in warm, soapy water; then rinse thoroughly. Allow the cuff to air dry, then insert the
latex inflation bag.
CAUTION:
8-4
When ironing or pressing the cuffs, be aware that the
Velcro® fasteners can melt at temperatures above 325°F,
162°C.

Battery Replacement and Maintenance
Battery Replacement
1. Open battery compartment door, on left side of unit, by sliding the tab down.
2. Press the release button, located above the battery, to eject the battery. Slide out old
battery.
3. Slide in replacement battery until it clicks into place.
4. Close battery compartment door.
Battery Maintenance
Due to the self-discharge characteristics of this type of battery, it is imperative that it is
charged after 6 to 9 months of storage (or unit not in use). If not, permanent loss of capacity
may occur as a result of sulfation. Charge retention at 20oC is 6 months to 83%.
The batteries used in the Passport XG Monitor are of sealed lead acid construction. This
battery type may be subject to local regulations regarding disposal. At the end of the battery
life, dispose of the batteries in accordance with any local regulations.
8.6.8
Recorder Paper Replacement
The instructions below describe the replacement of recorder paper. Use only recommended
recorder paper, P/N 0083-00-0422. This ensures that the print quality is acceptable and
reduces print head wear.
1. Open recorder door by pressing the paper eject button (upper right corner with paper
roll icon on it).
NOTE:
If the recorder’s door does not open completely, carefully
pull it until it is completely open.
2. Remove empty paper spool by pulling it out gently.
3. Insert new paper roll between the two rounded tabs of the paper holder with the
sensitive (shiny) side of the paper facing the print head at the top of the recorder (paper
feeding off of the spool from the bottom).
4. Unroll approximately 4 inches of paper.
5. Align the paper across the top of the metal bar.
6. Holding the paper in place, close recorder door.
7. To ensure that the paper is aligned properly and has not been pinched in the door, pull
the loose edge out a couple of inches. If the paper jams, open the door and return to
step 5.
8.6.9
Care and Storage of Thermal Chart Paper
Thermal Chart Paper is chemically treated and the permanency of a recording is affected by
storage and handling conditions. These conditions are:
• Ultraviolet Light
We recommend storing the recordings in a filing cabinet within a few days of printing. Long
term exposure to natural or artificial U.V. sources may be detrimental.

User Preventive Maintenance Introduction
Preventive Maintenance
• Storage Temperature and Humidity
Keep the recordings in a cool and dry area for a longer lasting image. Extreme temperature
and humidity (above 80° F and 80% Humidity) should be avoided.
• Solvent Reactions
Do not store the recordings in plastic bags, acetate sheet protectors, and similar items made
from petroleum products. These products emit a small amount of vapor which will, over a
period of time, deteriorate the image on the chart paper.
• Adhesive Tape
Never place adhesive tape over recordings. The reaction between the adhesive compound
and the Chemical/Thermal paper can destroy the image within hours.
• Archives
We recommend that if long term archives are required, make a photocopy of the recordings
as back-up. Under normal office filing conditions the recordings should retain acceptable
image quality for about 5 years.
