through the bus. Additionally, the meters have a feature that allows a remote
computer to directly control the outputs of the meter. With an RS232 or RS485
card installed, it is possible to configure the meter using a Windows® based
program. The configuration data can be saved to a file for later recall.
A linear DC output signal is available as an optional Plug-in card for the PAXI
only. The card provides either 20 mA or 10 V signals. The output can be scaled
independent of the input range and can track any of the counter or rate displays.
Once the meters have been initially configured, the parameter list may be
locked out from further modification in its entirety or only the setpoint values
can be made accessible.
The meters have been specifically designed for harsh industrial environments.
With NEMA 4X/IP65 sealed bezel and extensive testing of noise effects to CE
requirements, the meter provides a tough yet reliable application solution.
GENERAL DESCRIPTION
The PAX Digital Input Panel Meters offer many features and performance
capabilities to suit a wide range of industrial applications. Available in three
different models, PAXC Counter, PAXR Rate Meter and the PAXI which offers
both counting and rate in the same package. Refer to pages 4 - 5 for the details
on the specific models. The PAXC and PAXR offer only the Setpoint Option,
while the PAXI is the fully featured version offering all the capabilities as
outlined in this bulletin. The optional plug-in output cards allow the opportunity
to configure the meter for present applications, while providing easy upgrades
for future needs.
The meters employ a bright 0.56" LED display. The unit is available with a
red sunlight readable or standard green LED display. The intensity of the
display can be adjusted from dark room applications up to sunlight readable,
making it ideal for viewing in bright light applications.
The meters accept digital inputs from a variety of sources including switch
contacts, outputs from CMOS or TTL circuits, magnetic pickups and all
standard RLC sensors. The meter can accept directional, uni-directional or
Quadrature signals simultaneously. The maximum input signal varies up to 34
KHz depending on the count mode and function configurations programmed.
Each input signal can be independently scaled to various process values.
The Rate Meters provide a MAX and MIN reading memory with
programmable capture time. The capture time is used to prevent detection of false
max or min readings which may occur during start-up or unusual process events.
The meters have four setpoint outputs, implemented on Plug-in option cards.
The Plug-in cards provide dual FORM-C relays (5A), quad FORM-A (3A), or
either quad sinking or quad sourcing open collector logic outputs. The setpoint
alarms can be configured to suit a variety of control and alarm requirements.
Communication and Bus Capabilities are also available as option cards for
the PAXI only. These include RS232, RS485, Modbus, DeviceNet, and
Profibus-DP. Readout values and setpoint alarm values can be controlled

PROGRAMMING SOFTWARE
The SFPAX is a Windows® based program that allows configuration of the
PAX meter from a PC. Using the SFPAX makes it easier to program the PAX
meter and allows saving the PAX program in a PC file for future use. On-line
help is available within the software. A PAX serial plug-in card is required to
program the meter using the software.

1.0 INSTALLING
METER
THE
While holding the unit in place, push the panel latch over the rear of the unit
so that the tabs of the panel latch engage in the slots on the case. The panel
latch should be engaged in the farthest forward slot possible. To achieve a
proper seal, tighten the latch screws evenly until the unit is snug in the panel
(Torque to approximately 7 in-lbs [79N-cm]). Do not over-tighten the screws.
Installation
The PAX meets NEMA 4X/IP65 requirements when properly installed. The
unit is intended to be mounted into an enclosed panel. Prepare the panel cutout
to the dimensions shown. Remove the panel latch from the unit. Slide the panel
gasket over the rear of the unit to the back of the bezel. The unit should be
installed fully assembled. Insert
the unit into the panel cutout.
Installation Environment
The unit should be installed in a location that does not exceed the operating
temperature and provides good air circulation. Placing the unit near devices
that generate excessive heat should be avoided.
The bezel should only be cleaned with a soft cloth and neutral soap product.
Do NOT use solvents. Continuous exposure to direct sunlight may accelerate
the aging process of the bezel.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate the
keypad of the unit.
2.0 SETTING
THE
JUMPER
AND
To access the jumper and switches, remove the meter base from the meter
case by firmly squeezing and pulling back on the side rear finger tabs. This
should lower the latch below the case slot (which is located just in front of the
finger tabs). It is recommended to release the latch on one side, then start the
other side latch.
DIP SWITCHES
Warning: Exposed line voltage exists on the circuit boards. Remove
all power to the meter and load circuits before accessing inside of
the meter.
2.1 SETTING THE JUMPER
2.2 SETTING THE INPUT DIP SWITCHES
The meter has one jumper for user input logic. When using the user inputs
this jumper must be set before applying power. The Main Circuit Board figure
shows the location of the jumper and DIP switch.
The user input jumper determines signal logic for the user inputs, when they
are used with user functions or for input signal direction. All user inputs are set
by this jumper.
The meter has six DIP switches for Input A and Input B terminal set-up that
must be set before applying power. NOTE: The PAXR only uses switches 1-3.

3.0 INSTALLING PLUG-IN CARDS
The Plug-in cards are separately purchased optional cards that perform
specific functions. These cards plug into the main circuit board of the meter. The
Plug-in cards have many unique functions when used with the PAX. The
literature that comes with these cards should be discarded, unless it specifically
states in the Plug-in Card literature that the information applies to the PAX.
Note: The PAXC and PAXR only use the setpoint option card.
To Install:
1. With the case open, locate the Plug-in card connector for the card type to be
installed. The types are keyed by position with different main circuit board
connector locations. When installing the card, hold the meter by the rear
terminals and not by the front display board.*
2. Install the Plug-in card by aligning the card terminals with the slot bay in the
rear cover. Be sure the connector is fully engaged and the tab on the Plug-in
card rests in the alignment slot on the display board.
3. Slide the meter base back into the case. Be sure the rear cover latches fully
into the case.
4. Apply the Plug-in card label to the bottom side of the meter in the designated
area. Do Not Cover the vents on the top surface of the meter. The surface of
the case must be clean for the label to adhere properly.
CAUTION: The Plug-in card and main circuit board contain
static sensitive components. Before handling the cards, discharge
static charges from your body by touching a grounded bare metal
object. Ideally, handle the cards at a static controlled clean
workstation. Also, only handle the cards by the edges. Dirt, oil or
other contaminants that may contact the cards can adversely
affect circuit operation.

4.0 WIRING
THE
METER
b. Connect the shield to earth ground at both ends of the cable, usually when
the noise source frequency is above 1 MHz.
c. Connect the shield to common of the meter and leave the other end of the
shield unconnected and insulated from earth ground.
3. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be ran in metal conduit that is properly
grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter.
4. Signal or Control cables within an enclosure should be routed as far as possible
from contactors, control relays, transformers, and other noisy components.
5. In extremely high EMI environments, the use of external EMI suppression
devices, such as ferrite suppression cores, is effective. Install them on Signal
and Control cables as close to the unit as possible. Loop the cable through the
core several times or use multiple cores on each cable for additional
protection. Install line filters on the power input cable to the unit to suppress
power line interference. Install them near the power entry point of the
enclosure. The following EMI suppression devices (or equivalent) are
recommended:
Ferrite Suppression Cores for signal and control cables:
Fair-Rite # 0443167251 (RLC# FCOR0000)
TDK # ZCAT3035-1330A
Steward # 28B2029-0A0
Line Filters for input power cables:
Schaffner # FN610-1/07 (RLC# LFIL0000)
Schaffner # FN670-1.8/07
Corcom # 1 VR3
Note: Reference manufacturer’s instructions when installing a line filter.
6. Long cable runs are more susceptible to EMI pickup than short cable runs.
Therefore, keep cable runs as short as possible.
7. Switching of inductive loads produces high EMI. Use of snubbers across
inductive loads suppresses EMI.
Snubber: RLC# SNUB0000.
WIRING OVERVIEW
Electrical connections are made via screw-clamp terminals located on the
back of the meter. All conductors should conform to the meter’s voltage and
current ratings. All cabling should conform to appropriate standards of good
installation, local codes and regulations. It is recommended that the power
supplied to the meter (DC or AC) be protected by a fuse or circuit breaker.
When wiring the meter, compare the numbers embossed on the back of the
meter case against those shown in wiring drawings for proper wire position.
Strip the wire, leaving approximately 0.3" (7.5 mm) bare lead exposed (stranded
wires should be tinned with solder.) Insert the lead under the correct screwclamp terminal and tighten until the wire is secure. (Pull wire to verify
tightness.) Each terminal can accept up to one #14 AWG (2.55 mm) wire, two
#18 AWG (1.02 mm), or four #20 AWG (0.61 mm).
EMC INSTALLATION GUIDELINES
Although this meter is designed with a high degree of immunity to ElectroMagnetic Interference (EMI), proper installation and wiring methods must be
followed to ensure compatibility in each application. The type of the electrical
noise, source or coupling method into the meter may be different for various
installations. The meter becomes more immune to EMI with fewer I/O
connections. Cable length, routing, and shield termination are very important
and can mean the difference between a successful or troublesome installation.
Listed below are some EMC guidelines for successful installation in an
industrial environment.
1. The meter should be mounted in a metal enclosure, which is properly
connected to protective earth.
2. Use shielded (screened) cables for all Signal and Control inputs. The shield
(screen) pigtail connection should be made as short as possible. The
connection point for the shield depends somewhat upon the application.
Listed below are the recommended methods of connecting the shield, in order
of their effectiveness.
a. Connect the shield only at the panel where the unit is mounted to earth
ground (protective earth).

4.3 INPUT WIRING
CAUTION: Sensor input common is NOT isolated from user input common. In order to preserve the safety of the meter application, the sensor input
common must be suitably isolated from hazardous live earth referenced voltage; or input common must be at protective earth ground potential. If not,
hazardous voltage may be present at the User Inputs and User Input Common terminals. Appropriate considerations must then be given to the potential
of the user input common with respect to earth ground; and the common of the isolated plug-in cards with respect to input common.

RS232 Communications
RS485 Communications
The RS485 communication standard allows the connection of up to 32
devices on a single pair of wires, distances up to 4,000 ft. and data rates as high
as 10M baud (the PAX is limited to 19.2k baud). The same pair of wires is used
to both transmit and receive data. RS485 is therefore always half-duplex, that is,
data cannot be received and transmitted simultaneously.

RS232 is intended to allow two devices to communicate over distances up to
50 feet. Data Terminal Equipment (DTE) transmits data on the Transmitted Data
(TXD) line and receives data on the Received Data (RXD) line. Data Computer
Equipment (DCE) receives data on the TXD line and transmits data on the RXD
line. The PAX emulates a DTE. If the other device connected to the meter also
emulates a DTE, the TXD and RXD lines must be interchanged for
communications to take place. This is known as a null modem connection. Most
printers emulate a DCE device while most computers emulate a DTE device.
Some devices cannot accept more than two or three characters in succession
without a pause in between. In these cases, the meter employs a busy function.
As the meter begins to transmit data, the RXD line (RS232) is monitored to
determine if the receiving device is “busy”. The receiving device asserts that it
is busy by setting the RXD line to a space condition (logic 0). The meter then
suspends transmission until the RXD line is released by the receiving device.

THE
METER
OVERVIEW
PROGRAMMING MENU
Shaded areas represent program access that is model dependent.
PROGRAMMING MODE ENTRY (PAR KEY)
PROGRAMMING MODE EXIT (DSP KEY or at PAR KEY)
The meter normally operates in the Display Mode. No parameters can be
programmed in this mode. The Programming Mode is entered by pressing the
PAR key. If it is not accessible then it is locked by either a security code, or a
hardware lock.
Two types of programming modes are available. Quick Programming Mode
permits only certain parameters to be viewed and/or modified. All meter
functions continue to operate except the front panel keys change to
Programming Mode Operations. Quick Programming Mode is configured in
Module 3. Full Programming Mode permits all parameters to be viewed and
modified. In this mode, incoming counts may not be recognized correctly, the
front panel keys change to Programming Mode Operations and certain user
input functions are disabled. Throughout this document, Programming Mode
(without Quick in front) always refers to “Full” Programming.
The Programming Mode is exited by pressing the DSP key (from anywhere
in the Programming Mode) or the PAR key (with displayed). This will
commit any stored parameter changes to memory and return the meter to the
Display Mode. If a parameter was just changed, the PAR key should be pressed
to store the change before pressing the DSP key. (If power loss occurs before
returning to the Display Mode, verify recent parameter changes.)
MODULE ENTRY (ARROW & PAR KEYS)
FACTORY SETTINGS
The Programming Menu is organized into nine modules. These modules group
together parameters that are related in function. The display will alternate between
and the present module. The arrow keys (F1 and F2) are used to select
the desired module. The displayed module is entered by pressing the PAR key.
Factory Settings may be completely restored in Module 9. This is a good
starting point for programming problems. Most parameters can be left at their
Factory Settings without affecting basic start-up. These parameters are
identified throughout the module explanations.
MODULE MENU (PAR KEY)
ALTERNATING SELECTION DISPLAY
Each module has a separate module menu (which is shown at the start of each
module discussion). The PAR key is pressed to advance to a particular parameter
to be changed, without changing the programming of preceding parameters.
After completing a module, the display will return to . Programming may
continue by accessing additional modules.
In the explanation of the modules, the following dual display with arrows will
appear. This is used to illustrate the display alternating between the parameter
on top and the parameter’s Factory Setting on the bottom. In most cases,
selections and values for the parameter will be listed on the right.
PROGRAMMING TIPS
It is recommended to start with Module 1 for counting and Module 4 for rate.
If lost or confused while programming, press the DSP key and start over. When
programming is complete, it is recommended to record the parameter
programming on the Parameter User Chart and lock out parameter
programming with a user input or lock-out code.
Indicates Program Mode Alternating Display
SELECTION / VALUE ENTRY (ARROW & PAR KEYS)
For each parameter, the display alternates between the present parameter and
the selections/value for that parameter. The arrow keys (F1 and F2) are used
to move through the selections/values for that parameter. Pressing the PAR key,
stores and activates the displayed selection/value. This also advances the meter
to the next parameter.
For numeric values, the RST key may be used to select a specific digit to be
changed. Once a digit is selected, the arrow keys are used to increment or
decrement that digit to the desired number.

This enables the prescaler output. The prescaler output is useful for
providing a lower frequency scaled pulse train to a PLC or another external
counter. On each falling edge of Input A, the prescaler output register
increments by the prescaler scale value (). When the register equals or
exceeds 1.0000, a pulse is output and the register is lowered by 1.0000. The
prescaler register is reset to zero whenever Counter A is reset (except for
Setpoint Counter Auto Reset). (See Prescaler Output Figure.)

8 DIGIT COUNT VALUES
Any counter display value below -99999 or above 999999 (less decimal
point) will consist of a two part display. This display alternates between the
least 6 significant digits and the remaining most significant digits beginning
with “” in the display. If the display exceeds ± 99999999 the display will roll
to zero and continue counting. Outputs cannot be set to counter values above 6
digits. The annunciator, indicating the counter being displayed, will flash when
the value is above 6 digits.
SCALING CALCULATIONS
Each counter has the ability to scale an input signal to a desired display
value. This is accomplished by the counter mode (x-
), scale factor (x),
scale multiplier (x) and decimal point (x). The scale factor is
calculated using:
COUNTER B RESET ACTION

1. Show feet to the hundredths (0.00) with 100 pulses per foot:
Scale Factor would be 100 / (100 x 1 x 1) = 1
(In this case, the scale multiplier and counter mode factor are 1)
2. Show feet with 120 pulses per foot: Scale Factor would be 1 / (120 x 1 x 1)
= 0.0083333. (In this case, the scale multiplier of 0.01 could be used: 1 / (120
x 1 x 0.01) = 0.83333 or show to hundredths (0.00): 100 / (120 x 1 x 1) =
0.8333.)
General Rules on Scaling
1. It is recommended that, the scale factor be as close as possible to, but not
exceeding 1.00000. This can be accomplished by increasing or decreasing
the counter decimal point position, using the scale multiplier, or selecting a
different count mode.
2. To double the number of pulses per unit, use counter modes direction X2 or
quad X2. To increase it by four times, use counter mode quad X4. Using
these modes will decrease the maximum input frequency.
3. A scale factor greater than 1.00000 will cause Counter display rounding. In
this case, digit jumps could be caused by the internal count register rounding
the display. The precision of a counter application cannot be improved by
using a scale factor greater than 1. 00000.
4. The number of pulses per single unit must be greater than or equal to the
DDD value for the scale factor to be less than or equal to one.
5. Lowering the scale factor can be accomplished by lowering the counter
decimal position. (Example: 100 (Hundredths)/10 pulses = 10.000 lowering
to 10 (Tenths)/10 = 1.000.)
The number of input counts is multiplied by the scale multiplier and the scale
factor to obtain the desired process value. A scale multiplier of 1 will result in
only the scale factor affecting the display. (Details on scaling calculations are
explained at the end of this section.)

6.4 MODULE 4 - RATE INPUT PARAMETERS () - PAXR & I
PARAMETER MENU
Non-linear Application – Up to 10 Scaling Points
Module 4 is the programming for the Rate parameters. For maximum input
frequency, Rate assignment should be set to when not in use. When set to
, the remaining related parameters are not accessible. The Rate value is
shown with an annunciator of ‘’ in the Display Mode.
Note: For PAXR, is actually on the unit’s display and is
actually on the unit’s display.
Non-linear processes may utilize up to nine segments (ten scaling points) to
provide a piece-wise linear approximation representing the non-linear function.
The Rate display will be linear throughout each individual segment (i.e.
between sequential scaling points). Thus, the greater the number of segments,
the greater the conformity accuracy. Several linearization equations are
available in the SFPAX software.
PAXI: RATE ASSIGNMENT
About Scaling Points
Each Scaling Point is specified by two programmable parameters: A desired
Rate Display Value () and a corresponding Rate Input Value (
).
Scaling points are entered sequentially in ascending order of Rate Input Value.
Two scaling points must be programmed to define the upper and lower
endpoints of the first linear segment. Setting !", automatically factory sets
the first scaling point to 0.0 for typical single segment, zero based applications.
When multiple segments are used, the upper scaling point for a given segment
becomes the lower scaling point for the next sequential segment. Thus, for each
additional segment used, only one additional scaling point must be programmed.
The following chart shows the Scaling Points, the corresponding Parameter
mnemonics, and the Factory Default Settings for each point.
For measuring the rate (speed) of pulses on Input A, select . For Input
B select . This assignment is independent of the counting modes.
LOW UPDATE TIME (DISPLAY UPDATE) *
to seconds
The Low Update Time is the minimum amount of time between display
updates for the Rate display. Values of 0.1 and 0.2 seconds will update the
display correctly but may cause the display to appear unsteady. The factory
setting of 1.0 will update the display every second minimum.
SEGMENT
1
HIGH UPDATE TIME (DISPLAY ZERO) *
to seconds
The High Update Time is the maximum amount of time before the Rate
display is forced to zero. (For more explanation, refer to Input Frequency
Calculation.) The High Update Time must be higher than the Low Update Time
and higher than the desired slowest readable speed (one divided by pulses per
second). The factory setting of 2.0, will force the display to zero for speeds
below 0.5 Hz or a pulse every 2 seconds.

RATE INPUT VALUE FOR SCALING POINT 2
RATE SCALING
To scale the Rate, enter a Scaling Display value with a corresponding Scaling
Input value. (The Display and Input values can be entered by Key-in or Applied
Methods.) These values are internally plotted to a Display value of 0 and Input
value of 0 Hz. A linear relationship is formed between these points to yield a
rate display value that corresponds to the incoming input signal rate. The PAXI
and PAXR are capable of showing a rate display value for any linear process.
to Enter the corresponding Rate Input Value for the second Scaling Point by
using the arrow keys. Rate Input values for scaling points can be entered by
using the Key-in or the Applied method described below.
KEY-IN SCALING METHOD CALCULATION
Key-in Method:
If a display value versus input signal (in pulses per second) is known, then
those values can be entered into Scaling Display (x) and Scaling Input
(
x). No further calculations are needed.
If only the number of pulses per ‘single’ unit (i.e. # of pulses per foot) is
known, then it can be entered as the Scaling Input value and the Scaling Display
value will be entered as the following:
Enter the Rate Input value (
) that corresponds to the entered Rate
Display value () by pressing the F1 or F2 keys. This value is always in
pulses per second (Hz).
Applied Method:
Apply an external rate signal to the appropriate input terminals. At the Rate
Input Value (
) press and hold the F1 and F2 keys at the same time. The
applied input frequency (in Hz) will appear on the display. (To verify correct
reading wait for at least the length of the Low Update Time. Then press and
hold the F1 and F2 keys at the same time again. The new value should be ±
0.1% of the previous entered value.) Press PAR to enter the displayed
frequency as the Rate Input value. To prevent the displayed value from being
entered, press DSP. This will take the meter out of Programming Mode and the
previous Rate Input value will remain.
Rounding values other than one round the Rate display to the nearest
increment selected (e.g. rounding of ‘5’ causes 122 to round to 120 and 123 to
round to 125). Rounding starts at the least significant digit of the Rate display.
to Minute

The meter determines the input frequency by summing the number of falling
edges received during a sample period of time. The sample period begins on the
first falling edge. At this falling edge, the meter starts accumulating time
towards Low Update and High Update values. Also, the meter starts
accumulating the number of falling edges. When the time reaches the Low
Update Time value, the meter looks for one more falling edge to end the sample
period. If a falling edge occurs (before the High Update Time value is reached),
the Rate display will update to the new value and the next sample period will
start on the same edge. If the High Update Time value is reached (without
receiving a falling edge after reaching Low Update Time), then the sample
period will end but the Rate display will be forced to zero. The High Update
Time value must be greater than the Low Update Time value. Both values must
be greater than 0.0. The input frequency calculated during the sample period, is
then shown as a Rate value determined by either scaling method.
MAXIMUM CAPTURE DELAY TIME *
to seconds
When the Rate value is above the present Maximum rate value for the
entered amount of time, the meter will capture that Rate value as the new
Maximum value. A delay time helps to avoid false captures of sudden short
spikes. Maximum detection will only function if Rate is assigned to Input A or
B. The Maximum rate value is shown with an annunciator of ‘’ in the display
and will continue to function independent of being displayed.

NOTES:
1. If # of pulse per unit is less than 10, then multiply both Input and Display
values by 10.
2. If # of pulse per unit is less than 1, then multiply both Input and Display
values by 100.
3. If the Display value is raised or lowered, then Input value must be raised
or lowered by the same proportion (i.e. Display value for per hour is
entered by a third less (1200) then Input value is a third less of # of pulses
per unit). The same is true if the Input value is raised or lowered, then
Display value must be raised or lowered by the same proportion.
4. Both values must be greater than 0.0.
RATE DISPLAY ROUND *
RATE PER
to seconds
When the Rate value is below the present Minimum rate value for the entered
amount of time, the meter will capture that Rate value as the new Minimum
value. A delay time helps to avoid false captures of sudden short spikes.
Minimum detection will only function if Rate is assigned to Input A or B. The
Minimum rate value is shown with an annunciator of ‘’ in the display and will
continue to function independent of being displayed.
RATE DISPLAY EXCEEDED
If the rate of the input signal causes a display that exceeds the capacity of the
Rate display (5 digits, 99999), then the display will indicate an overflow
condition by showing “ ”. During this overflow condition, the Minimum
and Maximum rate values will stay at their values even during resets.

Module 5 is the programming for Counter C. For maximum input frequency,
the counter operating mode should be set to when not in use. When set to

COUNTER C SCALE MULTIPLIER
Counter C counts the incoming pulses from Counter A input
as per Counter A mode of operation. The signal is scaled
only according to Counter C parameters.
Counter C counts the incoming pulses from Counter A and B
inputs as per Counter A and B modes of operation. The
result is scaled only according to Counter C parameters.
(Example: If Counter A is set for Count X1 mode and Counter
B is set for Count X2 mode, then Counter C will increment by
1 for each pulse received on Input A and increment by 2 for
each pulse received on Input B less any effects of scaling.)
The number of input counts is multiplied by the scale multiplier and the scale
factor to obtain the desired process value. A scale multiplier of 1 will result in
only the scale factor affecting the display. (Details on scaling calculations are
explained at the end of Module 1 section.)
Counter C counts the incoming pulses from Counter A and B
inputs as per Counter A and B modes of operation and
subtracts the B counts from the A counts. The result is scaled
only according to Counter C parameters. (Example: If
Counter A is set for Count X1 mode and Counter B is set for
Count X2 mode, then Counter C will increment by 1 for each
pulse received on Input A and decrement by 2 for each pulse
received on Input B less any effects of scaling.)
COUNTER C COUNT LOAD VALUE
Note: When using Add Ab or Sub Ab, Counter A, B and C must all be reset
at the same time for the math to be performed on the display values.
SLAVE
to The number of input counts is multiplied by the scale factor and the scale
multiplier to obtain the desired process value. A scale factor of 1.00000 will
result in the display of the actual number of input counts. For (Numeric
transmissions) modes of operation, the input signal is scaled directly. For and % modes of operation, the math is performed on the input signals
and then the result is scaled. To achieve correct results, both Input A and Input
B must provide the same amount of pulses per unit of measurement. (Details on
scaling calculations are explained at the end of Module 1 section.)

Numeric data sent to the meter must be limited to Transmit Details listed in
the Register Identification Chart. Leading zeros are ignored. Negative numbers
must have a minus sign. The meter ignores any decimal point and conforms the
number to the scaled resolution. (ie. The meter’s scaled decimal point position
is set for 0.0 and 25 is written to a register. The value of the register is now 2.5.
In this case, write a value of 250 to equal 25.0).
Note: Since the meter does not issue a reply to value change commands, follow
with a transmit value command for readback verification.
Transmitting Data From the Meter
Data is transmitted from the meter in response to either a transmit command
(T), a print block command (P) or User Function print request. The response
from the meter is either a full field transmission or an abbreviated transmission.
The meter response is established in Module 7.
Command String Construction
The command string must be constructed in a specific sequence. The meter
does not respond with an error message to invalid commands. The following
procedure details construction of a command string:
Full Transmission
1. The first characters consist of the Node Address Specifier (N) followed by a
2 character address number. The address number of the meter is
programmable. If the node address is 0, this command and the node address
itself may be omitted. This is the only command that may be used in
conjunction with other commands.
2. After the optional address specifier, the next character is the command
character.
3. The next character is the Register ID. This identifies the register that the
command affects. The P command does not require a Register ID character.
It prints according to the selections made in print options.
4. If constructing a value change command (writing data), the numeric data is
sent next.
5. All command strings must be terminated with the string termination
characters *, $ or when Counter C is set for slave mode <CR>. The meter
does not begin processing the command string until this character is received.
See Timing Diagram figure for differences between terminating characters.

mnemonic. The numeric data is transmitted next.
The numeric field (bytes 7 to 18) is 12 characters long. When the requested
value exceeds eight digits for count values or five digits for rate values, an *
(used as an overflow character) replaces the space in byte 7. Byte 8 is always a
space. The remaining ten positions of this field (bytes 9 to 18) consist of a minus
sign (for negative values), a floating decimal point (if applicable), and eight
positions for the requested value. The data within bytes 9 to 18 is right-aligned
with leading spaces for any unfilled positions.
The end of the response string is terminated with <CR> (byte 19), and <LF>
(byte 20). When a block print is finished, an extra <SP> (byte 21), <CR> (byte
22), and <LF> (byte 23) are used to provide separation between the
transmissions.

Writing to this register (VW) while the analog output is in the Manual Mode
causes the output signal level to update immediately to the value sent. While in
the Automatic Mode, this register may be written to, but it has no effect until the
analog output is placed in the manual mode. When in the Automatic Mode, the
meter controls the analog output signal level. Reading from this register (TW)
will show the present value of the analog output signal.
Example: VW2047 will result in an output of 10.000 mA, 12.000 mA or
5.000V depending on the range selected.
Auto/Manual Mode Register (MMR) ID: U
This register sets the controlling mode for the outputs. In Auto Mode (0) the
meter controls the setpoint and analog output. In Manual Mode (1) the outputs
are defined by the registers SOR and AOR. When transferring from auto mode
to manual mode, the meter holds the last output value (until the register is
changed by a write). Each output may be independently changed to auto or
manual. In a write command string (VU), any character besides 0 or 1 in a field
will not change the corresponding output mode.

In Automatic Mode, the meter controls the setpoint output state. In Manual
Mode, writing to this register (VX) will change the output state. Sending any
character besides 0 or 1 in a field or if the corresponding output was not first in
manual mode, the corresponding output value will not change. (It is not
necessary to send least significant 0s.)
Example: VX10 will result in output 1 on and output 2 off.
COUNTER C SLAVE COMMUNICATIONS
Counter C may be programmed for , to act as a serial slave display. By doing this, the carriage return <CR>
is added as a valid command terminator character for all serial command strings. The <CR> as a terminator may be
very useful for standard serial commands, even if Counter C is never displayed or sent a slave message. The $
terminator should not be used in the slave mode. If numeric values are not to be saved to EPROM then send the value
as a literal transmission with <CR> terminator.
The Counter C slave display is right aligned. It has a capacity of displaying six characters. When less than six
characters are received, blank spaces will be placed in front of the characters. If more than six characters are sent,
then only the last six are displayed. The meter has a 192 character buffer for the slave display. If more than 192
characters are sent, the additional characters are discarded until a terminator is received. Counter C processes
numeric and literal transmissions differently.
Numeric Transmissions
Literal Transmissions
When a string that does not begin with #, T, V, P or R is received, the meter
processes it as a Numeric transmission. In this case, only the recognized numbers
and punctuation are displayed. All other characters in the string are discarded. If
a negative sign appears anywhere in the string the resulting number will be
negative. Only the most significant decimal point is retained. If no numerical
characters are received, then the numeric value will be zero. The numeric display
can be used for setpoint (boundary action only) and analog output functions.
When using this display for setpoint and analog output values, the decimal point
position must match the programming entered through the front panel. The
numeric value is retained in Counter C memory until another Numeric
transmission is received.
When a string that begins with # is received, the meter processes it as a Literal
transmission. In this case, any unrecognized characters will be replaced with a
space. A Literal display will replace a Numeric value in the Counter C display.
However, it will not remove a previous Numeric value from Counter C memory
or prevent the Counter C outputs from functioning with the Numeric value.
Literal transmissions are only possible when using RS232 or RS485 cards.
Recognized Characters = a, b, c, d, e, f, g, h, i, j, l, n, o, p, q, r, s, t, u,
y, z (in upper or lower case)
Recognized Numbers = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

SERIAL TIMING
COMMAND RESPONSE TIME
The meter can only receive data or transmit data at any one time (half-duplex
operation). During RS232 transmissions, the meter ignores commands while
transmitting data, but instead uses RXD as a busy signal. When sending
commands and data to the meter, a delay must be imposed before sending
another command. This allows enough time for the meter to process the
command and prepare for the next command.
At the start of the time interval t1, the computer program prints or writes the
string to the com port, thus initiating a transmission. During t1, the command
characters are under transmission and at the end of this period, the command
terminating character (*, $ or slave only <CR>) is received by the meter. The
time duration of t1 is dependent on the number of characters and baud rate of
the channel.

t1 = (10 times the # of characters) / baud rate
At the start of time interval t2, the meter starts the interpretation of the
command and when complete, performs the command function. This time
interval t2 varies (See Timing Diagrams). If no response from the meter is
expected, the meter is ready to accept another command.
If the meter is to reply with data, the time interval t2 is controlled by the use
of the command terminating character. The ‘*’ or ‘<CR>’ terminating character
results in a response time window of 50 msec. minimum and 100 msec.
maximum. This allows sufficient time for the release of the sending driver on
the RS485 bus. Terminating the command line with ‘$’ results in a response
time window (t2) of 2 msec. minimum and 50 msec. maximum. The faster
response time of this terminating character requires that sending drivers release
within 2 msec. after the terminating character is received.
At the beginning of time interval t3, the meter responds with the first
character of the reply. As with t1, the time duration of t3 is dependent on the
number of characters and baud rate of the channel. At the end of t3, the meter
is ready to receive the next command.
NO REPLY FROM METER
RESPONSE FROM METER
t3 = (10 times the # of characters) / baud rate
The maximum serial throughput of the meter is limited to the sum of the
times t1, t2 and t3.
COMMUNICATION FORMAT
Data is transferred from the meter through a serial communication channel.
In serial communications, the voltage is switched between a high and low level
at a predetermined rate (baud rate) using ASCII encoding. The receiving device
reads the voltage levels at the same intervals and then translates the switched
levels back to a character.
The voltage level conventions depend on the interface standard. The table
lists the voltage levels for each standard.

* Voltage levels at the Receiver
Data is transmitted one byte at a time with a variable idle period between
characters (0 to ∞). Each ASCII character is “framed” with a beginning start bit,
an optional parity bit and one or more ending stop bits. The data format and
baud rate must match that of other equipment in order for communication to
take place. The figures list the data formats employed by the meter.
Character Frame Figure
Parity bit
After the data bits, the parity bit is sent. The transmitter sets the parity bit to
a zero or a one, so that the total number of ones contained in the transmission
(including the parity bit) is either even or odd. This bit is used by the receiver
to detect errors that may occur to an odd number of bits in the transmission.
However, a single parity bit cannot detect errors that may occur to an even
number of bits. Given this limitation, the parity bit is often ignored by the
receiving device. The PAX meter ignores the parity bit of incoming data and
sets the parity bit to odd, even or none (mark parity) for outgoing data.
Start bit and Data bits
Data transmission always begins with the start bit. The start bit signals the
receiving device to prepare for reception of data. One bit period later, the least
significant bit of the ASCII encoded character is transmitted, followed by the
remaining data bits. The receiving device then reads each bit position as they are
transmitted.
Stop bit
The last character transmitted is the stop bit. The stop bit provides a single bit
period pause to allow the receiver to prepare to re-synchronize to the start of a
new transmission (start bit of next byte). The receiver then continuously looks
for the occurrence of the start bit. If 7 data bits and no parity is selected, then 2
stop bits are sent from the PAXI.

#
Before starting, verify that a precision meter with an accuracy of 0.05% or
better (voltmeter for voltage output and/or current meter for current output) is
connected and ready. Then perform the following procedure:
1. Use the arrow keys to display # and press PAR.
2. is displayed. Use the arrow keys to select & and press PAR.
3. Using the chart below, step through the five selections to be calibrated. At
each prompt, use the PAXI arrow keys to adjust the output so that the
external meter display matches the selection being calibrated. When the
external reading matches, or if the range is not being calibrated, press PAR.
The only item in the PAXI meter that can be calibrated
is the Analog Output. The Count A and B values are scaled
using the parameters in Module 1, Counter C value is scaled
using Module 5 and the Rate value is scaled using Module 4. If the meter appears
to be indicating incorrectly or inaccurately, refer to the Troubleshooting section.
When Analog Out recalibration is required (generally every 2 years), it
should be performed by qualified technicians using appropriate equipment.
Calibration does not change any user programmed parameters.
Calibration may be aborted by disconnecting power to the meter before
exiting Module 9. In this case, the existing calibration settings remain in effect.
