Warranty, Service, Repair, and
Return Policies and Instructions
The information contained in this document supersedes all similar information that
may be found elsewhere in this manual.
Total Customer Satisfaction – PCB
Piezotronics guarantees Total Customer
Satisfaction. If, at any time, for any
reason, you are not completely satisfied
with any PCB product, PCB will repair,
replace, or exchange it at no charge. You
may also choose to have your purchase
price refunded in lieu of the repair,
replacement, or exchange of the product.
Service – Due to the sophisticated nature
of the sensors and associated
instrumentation provided by PCB
Piezotronics, user servicing or repair is
not recommended and, if attempted, may
void the factory warranty. Routine
maintenance, such as the cleaning of
electrical connectors, housings, and
mounting surfaces with solutions and
techniques that will not harm the
physical material of construction, is
acceptable. Caution should be observed
to insure that liquids are not permitted to
migrate into devices that are not
hermetically sealed. Such devices should
only be wiped with a dampened cloth
and never submerged or have liquids
poured upon them.
Repair – In the event that equipment
becomes damaged or ceases to operate,
arrangements should be made to return
the equipment to PCB Piezotronics for
repair. User servicing or repair is not
recommended and, if attempted, may
void the factory warranty.
Calibration – Routine calibration of
sensors and associated instrumentation is
recommended as this helps build
confidence in measurement accuracy and
acquired data. Equipment calibration
cycles are typically established by the
users own quality regimen. When in
doubt about a calibration cycle, a good
“rule of thumb” is to recalibrate on an
annual basis. It is also good practice to
recalibrate after exposure to any severe
temperature extreme, shock, load, or
other environmental influence, or prior
to any critical test.
PCB Piezotronics maintains an ISO9001 certified metrology laboratory and
offers calibration services, which are
accredited by A2LA to ISO/IEC 17025,
with full traceablility to N.I.S.T. In
addition to the normally supplied
calibration, special testing is also
available, such as: sensitivity at elevated
or cryogenic temperatures, phase
response, extended high or low
frequency response, extended range, leak
testing, hydrostatic pressure testing, and
others. For information on standard
recalibration services or special testing,
contact your local PCB Piezotronics
distributor, sales representative, or
factory customer service representative.
Returning Equipment – Following
these procedures will insure that your
returned materials are handled in the
most expedient manner. Before returning
any equipment to PCB Piezotronics,
contact your local distributor, sales
representative, or factory customer
service representative to obtain a Return

Introduction: Safety Considerations
1
WARNING SYMBOLS AND TERMS
The following symbols and terms may be found on the equipment described in this manual.
This symbol on the unit indicates that the user should refer to the operating instructions located in the manual.
This symbol on the unit indicates that high voltage may be present. Use standard safety precautions to avoid personal
contact with this voltage.
This symbol indicates that the test fixture, Model 483C40, must be connected to earth ground via the power cord.
The WARNING heading used in this manual explains dangers that might result in personal injury or death. Always read
the associated information very carefully before performing the indicated procedure.
The Caution heading used in this manual explains hazards that could damage the instrument.
WARNING 1: The power supply/signal conditioner should not be opened by anyone other than qualified service
personnel. This product is intended for service by qualified personnel who recognize shock hazards and are familiar with
the safety precautions required to avoid injury.
WARNING 2: This equipment is designed with user safety in mind; however, the protection provided by the equipment
may be impaired if the equipment is used in a manner not specified by PCB Piezotronics, Inc.
Caution 1: Cables can kill your equipment. High voltage ElectroStatic Discharge (ESD) can damage electrical devices.
Similar to a capacitor, a cable can hold a charge caused by triboelectric transfer, such as that which occurs in the
following:
•
•
•
•
Laying on and moving across a rug.
Any movement through air.
The action of rolling out a cable.
Contact to a non-grounded person
The solution for product safety: 1) Connect the cables only with the AC power off. 2) Temporarily “short” the end of the
cable before attaching it to any signal input or output.
Caution 2: ESD considerations should be made prior to performing any internal adjustments on the equipment. Any
piece of electronic equipment is vulnerable to ESD when opened for adjustments. Internal adjustments should therefore
be done ONLY at an ESD-safe work area. Many products have ESD protection, but the level of protection may be
exceeded by extremely high voltage that is typically present in normal situations.

Installation
This signal conditioner model comes in a standard 19-inch rack mount enclosure with a 1U (1.75”) height. The enclosure
should be located in such a way as to allow convenient access to the power outlet for disconnect purposes. Since these
models have low power consumption, they can be located in confined environments.
1-4.1. Grounding Techniques
Integrating this model into an application that links the outputs to other test equipment powered by line voltages may lead
to errors or loss of signal-to-noise ratio due to ground loops. The evidence of ground loops is easily seen whenever the
fundamental frequency (50 or 60 Hz) or a multiple of the fundamental frequency is present in the system when the
sensors are “at rest.” In order to maintain the operating specification of noise and reduce the effects of line interference,
proper grounding techniques should be used. The following procedure may be helpful:
1. Make sure the signal ground lines of all equipment are tied together. The signal grounds of the channels are typically
tied together via the case of the input and output BNC connectors. The individual channels of these models have their
signal ground line tied together internally at the power supply.
2. Insure that the sensor does not pick up line noise from the body under test. The case of the sensor should be isolated
from the body under (ground) using an isolation pad. The isolation pad breaks the loop formed by the signal path of the
sensor to the signal conditioner and the return (ground) from the signal conditioner back to the sensor.
3. Make sure that all equipment signal grounds of the test system are tied to the Earth ground at a single point and the
connections linking the equipment ground are made using a wire that can provide a very low impedance connection.
1-5.
Operation: Standard AC Line
Plug the line cord into a 120V/60 Hz or 230V/50 Hz power source and toggle the “ON/OFF” switch.
CAUTION: Refer to the rear panel for proper input voltage and currents.
1-6.
Maintenance and Repair
It is not recommended that the customer attempt repair of this model in the field. Should trouble occur, contact
the factory for assistance. If the unit becomes dusty and dirty, it may be wiped off with a soft cloth.
MODEL 483C40 GENERAL OPERATION MANUAL
2-0.
THEORY OF OPERATION
2-1.
Sensor Excitation
4
ICP® refers to a low output impedance voltage mode sensor combining an integrated circuit and a piezoelectric sensing
element in a single housing to provide a voltage output. This sensor is powered by a +24 VDC power supply having a
constant current, variable from 2 to 20 mA.
Sensor excitation occurs as the constant current of all channels are set. This model allows the constant current to be
adjusted between 2 and 20 mA to provide the required excitation for most applications. Special situations, such as
driving extra-long cables (more than 1000 ft) with high frequency or fast rise time pulses, may require increasing the
drive current to 12 mA or higher.
Figure 2 ICP® Sensor Excitation
When driving fast rise time pulses over long lines, system performances can be optimized by “tuning” the drive current to
the line; i.e. by finding the best current setting for the particular test of physical parameters. To determine the optimal
current setting, experiment with your particular test set up. To insure optimal accuracy in constant-current adjustment,
make sure all channels have sensors or simulated loads, similar to the one provided by the Model 401B04 Sensor
Simulator, consisting of a voltage amplifier similar to those found in ICP sensors.
2-2.
Input Protection
The input section has protection to limit the amplitude of the incoming signal to within +24 volts to ground. Reference
spec sheet for maximum input signal.
2-3.
ICP® Input Fault Detection
This model monitors two input fault conditions in ICP® mode, “short” and “open,” which indicate problems with sensor
input and is displayed through the front panel LEDs. Either case implies that the sensor is NOT functioning properly.
An input is shorted when it has a ground path for the sensor excitation and open when the sensor fails to draw the
excitation.
Two voltage comparators consist of a window comparator that has two reference voltages (Vref) representing thresholds
for “short” and “open.” When the sensor’s bias voltage (Vbias) exceeds the comparator range, the front panel input fault
LED lights.
NOTE: Red LED implies input fault.
MODEL 483C40 GENERAL OPERATION MANUAL

Figure 3 Input Fault Window Comparator with LED Indicator
2-4.
Input Interface
The input signal conditioning for each channel in ICP® mode provides a unity gain buffer with high-input impedance
amplifiers. With the AC coupled option it also eliminates the DC bias from the input signal with a 10-second time
constant.
Figure 4 Input Amplifier Configuration
Voltage mode is similar to ICP mode, except the excitation current is 0 mA. In charge mode, the signal from the charge
sensor is routed into a charge amplifier with a gain of 0.1, 1.0, or 10 mV/pC, followed by incrementel voltage gain.
2-5.
Gain
The Programmable Gain Amplification (PGA) block consists of a decimal gain amplifier. See Figure 5.
Figure 5 Selectable Gain Amplifier Configuration
2-5.1. Programmable Gain
The 483C40 has incremental gain. This is particularly useful in the standardization of groups of sensors. Consider the
following example, wherein the user desires to normalize sensitivities to 1 V/unit for each channel.

The gain is set via the computer interface command set (See the command strings in Section 3-0 in the Computer
Interface Programming Guide.)
MODEL 483C40 GENERAL OPERATION MANUAL
2-6.

Normalized Output Sensitivity
The definition of normalized output sensitivity is the calculation of the individual channel’s gain, depending on the
sensitivity of the sensor attached and the desired output sensitivity. This is simply a function of the desired output
sensitivity (in Volts/ unit) divided by the sensor’s sensitivity.
Gain =
1 Volt
/ Sensitivity (mV/unit)
Additionally, a feature to improve flexibility allows changing the output level to a value of 5 Volts/ unit instead of
normalized 1 Volt/ unit. Some users request the ability calculate the gain using a known input signal along with the sensor
sensitivity, and desired output level. The result of the request impacts the formula:
Gain =
1 Volt/
/ [Sensitivity (mV/unit) * Full Scale Input (units)]
Adding some simple error checking to insure the limits of the sensor and gain limits of the signal conditioner are not
exceeded completes the normalization process.
Gainnormalized = FSOT (V) / SENS * FSIN
Additional Considerations:
The storage of individual channel gains is stored in non-volatile memory locations. The new variables for each channel’s
sensitivity, Full Scale Output level, and Full Scale Input are stored in non-volatile memory locations when SAVS
command is sent to the unit.
The error checking should provide a flag if the desired normalized output level is not feasible due to gain limitations. The
gain required may be too large given the sensor sensitivity defined, or too small which implies the sensor will not be
capable measure the expected value. The typical sensor will output a signal up to ±5 Volts. The maximum swing may be
used in the error checking.
The 483C40 has the capability to provide signal conditioning for charge mode sensors in addition to the standard ICP
type. The sensitivity (mV/ pC) of the charge conversion will allow charge mode sensors (pC/ unit) to be normalized.
2.7.
Low Pass Input Filter
The 483C40’s 8 pole low pass input filter is useful for attenuating signals above the user’s band of interest, and for antialiasing of signals before digitization. High quality components are used to achieve 6 cutoff frequencies: 0.1, 0.3, 1.0,
3.0, 10.0, and 30.0 kHz (-10%). The Butterworth topology provides a maximally flat response in the passband and is
critically damped. Continuous-time stages are employed so that the clock noise associated with switched capacitor
elements is not an issue. This is especially significant because the filter is located prior to the gain stages.
2.8.
Overload Detection
2-8.1. Overload
The overload feature uses the same window comparator principle previously discussed. The +Vref is equal to the default
overload value of ±10 volts. When the input voltage (Vsignal of Figure 6) to the window comparator exceeds the
reference voltage limits, overload has occurred, and the comparator’s output, which is normally “high,” becomes “low.”
This “low” state illuminates the overload LED and triggers the latch of overload detection circuitry. During regular
measuring time, the latch holds the occurrence of overloads until the user reads its status through the computer interface.
MODEL 483C40 GENERAL OPERATION MANUAL
7
Figure 6 /Overload Window Comparator
2-9.
Connector Configuration
This model has eight BNC jack output connectors, located on the rear panel, which are used regardless of the input mode
being used. The rear panel also includes eight BNC jack input connectors that are used for all input modes.
2-10. Non-Volatile Memory
This feature provides a mechanism to save and restore a programmed configuration. The programmable settings are
saved when the unit receives a SAVS command and restored when the unit powers up. The unit’s non-volatile memory
may be reset to the factory default settings by using the RSET Command.
2-11. Transducer Electronic Data Sheet (TEDS) Interface:
TEDS sensors attach to the input connectors the same way a traditional ICP sensor is attached to the signal conditioner.
The TEDS interface requires the Ethernet computer interface, and the input mode option. The digital control and input
mode features automatically perform the TEDS read or write function. After the communication with the TEDS sensor is
complete the input mode returns to the input mode (charge or ICP) prior to the communication.
The current TEDS function will perform a read of the “raw” TEDS data and return the 32 bytes of TEDS sensor
EEPROM data and the 8 byte Application register contents, if it was programmed, and returns the data in an ASCII Hex
representation.

The Ethernet Interface enables these models to be fully controlled by a computer or laptop controller. With this
interface, the unit is able to become part of a fully automated system.
3-2.
Ethernet Communication
This signal conditioner is equipped with an Ethernet Interface so the unit’s IP address must be set up before any remote
communication can commence.
The steps to set the IP address are as follow:
• Connect, either directly with a crossover CAT5 cable or through a hub, to a single unit. This unit is presumed to
have a Unit ID of 1,
• Set the IP address using an independent utility from Lantronix called DeviceInstallerTM. This utility is provided
on the PCB MCSC application software installer CD and also available for download at the Lantronix website:
http://www.lantronix.com/device-networking/utilities-tools/device-installer.html
Once installed it can be accessed from the MCSC software from the ‘Help | Configure Ethernet Devices’ menu
item.
• After the DeviceInstallerTM application is installed, run it and the following screen will appear. Click on the
Search icon and the program will search for the Ethernet device internal to the signal conditioner unit. When
found, as shown below, details about the device show in the list. You can verify it is the correct unit by
comparing the Hardware (MAC) Address displayed to the one listed on the side of the signal conditioner unit.
•
Selecting an item from the list, shown below, highlights the item in the list and enables more icons.
•
Select Assign IP and the following screen will appear. Select whether you want to assign a static IP address that
is appropriate for your network or have it assigned from a network server. Subsequent steps are self-explanatory.
MODEL 483C40 GENERAL OPERATION MANUAL
•
9
Now you can use the assigned IP address to address the unit.
Important Note: The communication protocol requires a unit id as part of the command header. The unit id is
not the IP address. To send commands to the unit Via Ethernet you must address the TCP-IP packets with the
proper IP address and ensure the packet payload contains the correct Unit Id in the command header.
The XPort device should be configured properly for communication with the signal conditioner. If problems
occur please check the communication parameters of the device as shown below.
Navigate to the actual device as shown in the left panel above and then click on the ‘Web Configuration’ tab and clock on
the ‘Go’ button. This will cause the following screen to appear, just select ‘OK’. There are no login parameters defined.
MODEL 483C40 GENERAL OPERATION MANUAL

Following this screen the right panel will appear as shown below. Click on the ‘Connection’ item and check to see that
the parameters are shown as below and pay particular attention to the ‘Active Connection’ and ‘Endpoint’ Port items.
They should be set as shown below.
Next, check the Serial Settings. They should be 19200 baud, 8 data bits, no parity, 1 stop bit. And no flow control.
If any setting is changed click ‘Ok’ on the page and then activate the ‘Apply Settings’ item on the left side of the right
panel.

Command Format
The communication protocol incorporates the concept of 'Directed' and 'Global' commands at both the Unit and Channel
level with the following characteristics;
• Unit or Channel numbers =0 are global commands that affect either all units or all channels of a particular unit
or both.
• Directed commands that set a unit parameter are always acknowledged (ACK) with an ASCII message that
indicates '<Unit#>:<CMD>:ok’ if implemented with no errors or NAK with; <Unit#>:<CMD>:=<error#>’ if an
error was encountered.
• Directed commands that request a particular parameters setting (query) result in a query response being returned
• No response is ever given to a Global Unit command.
Command Format:
'Unit#:Ch#:Cmd[=|?]{<value1 >{,< value2 >}}{;Ch#:Cmd[=|?]{<value1>{,< value2>}}}\n\r
•
•
•
•
•
Each message must be preceded by a Unit# & Channel# (both of which could be 0)
Messages may contain multiple commands separated by a semicolon ‘;’.
The second and subsequent commands in a message shall not contain a unit number but shall contain a channel
number.
Each command in a message will evoke a response message if one is warranted (not global)
Query’s ('?') can only be directed to one unit but if the channel=0 then each channel's setting will be returned in
the order 0-MAXCHANNELS separated by a ':'
Command examples:
1:0:GAIN=100.2\r\n
1:1:GAIN=100.2;2:GAIN=120.3\r\n
1:3:GAIN=100.2;0:FLTR=1\r\n
unit 1,all channels gain set to 100.2
unit 1, channel 1 gain = 100.2; channel 2 gain = 120.3
unit 1, channel 3 gain = 100.2; all channel’s filter = ON
General Query Response Format
Unit#:Cmd:Ch#=<value>{; Ch#=<value>}…>{; Ch#=<value>}…\r\n
Responses to a query with a channel number=0 will return the setting of each channel in a list separated by
semicolons ‘;’.
If the target of the query is a unit setting (ex. current excitation) then the channel number returned is the 1st
channel of the board that processed the command.
3-7.
Multiple Board Models
The 483C40 has multiple main boards which appear as a contiguous set of channels; they are physically separate
and operate somewhat independently. A global channel command to set 8 channels on a unit will be handled by
each internal board simultaneously. However only the board with the channels designated as 1-4 will ACK the
command, the other board will remain silent.
Likewise, a global Query command will be responded to by the channel 1-4 board but will be ignored by the
channel 5-8 board. However, in order to facilitate efficient communications with the second board, a second unit
address was is used to query the second board. A user’s control application can direct global channel setting
queries to the second board of a unit by addressing the query to the secondary unit address of the unit. The
secondary unit address is defined to be the normal unit address plus 128 (ex. If a unit’s address is 1 then the 2nd
board’s address would be 129)

Commands
GAIN
SET GAIN: This command sets the programmable gain of a channel.
Setting:
The amplifier gain can be set directly by sending a Gain command:
1:0:GAIN=100.2\r\n (unit 1,all channels gain set to 100.2)
When a channels gain is set directly the unit will adjust the FSI parameter of the gain equation using the
following equation; FSI = (((FSO*1000)/Gain)/Sens) to ensure it remains valid.
Setting Response: 1:GAIN:ok
Query:
The Gain query returns all of the parameters used to determine it in a single response
Query Format: Unit#:Ch#:CMD?
Response format: Unit#:Cmd:Ch#:=Gain:SENS:FSO:FSI;
Query: 1:5:GAIN?
Response: 1:GAIN:5= 5.0: 10.0: 10.0: 200.0;
Global Gain Query: 1:0:GAIN?

SENS
The SENS command provides a mechanism to have the transducer Sensitivity influence the Gain setting of the
channel. Channel Gain is calculated using the equation;
Gain = FSO*1000/(FSI*SENS). If a Sensitivity is entered that caused the gain to exceed the amplifiers
capability the FSI component will be adjusted to keep the equation valid.
Setting:
1:0:SENS=20.2\r\n
Setting Response: 1:SENS:ok
(unit 1,all channels transducer sensitivity set to 20.2)
Query:
The SENS query returns the channels transducer sensitivity

Global Gain Query: 1:0:SENS?
Global Gain Response: 1:SENS:1= 6.0;2= 10.0;3= 10.0;4= 10.0;
FSCI
The FSCI command provides a scaling mechanism to automatically set the gain based on a known input level (in
EU) and what output level (in Volts) you would like that Full Scale input level to be represented by. For instance
1000g’s = 10Volts. These 2 values along with the transducer sensitivity set the gain. Channel Gain is calculated
using the equation: Gain = FSO*1000/(FSI*SENS).

RTED
The RTED query returns the TEDS information that is stored in the sensor or other, TEDS capable, in-line
module attached to a specific channel. The signal conditioners are IEEE 1451.4 compliant in that they will read
the DS2430A Application Register Status to see if it indicates the 64 bit Application Register has data in it. If so
it will read the Application register contents and return it followed by the contents of the TEDS EEPROM.
NOTE: The 1st byte of the DS2430A EEPROM data should contain the checksum of both the Application
Register contents and the EEPROM contents if the TEDS is IEEE 1451.4 compliant. No attempt is made to
validate or interpret the TEDS data.

UNID
The UNID command is used to set the units ID number. The Unit Id number is critical to remote
communications since it indicates to the unit which commands it should accept and respond to. Units are
typically shipped with a unit id of 1. If more than one unit is in the system and they will be communicated with
remotely the user must set a unique id in each unit. This can be done through the front panel interface, if one
exists, or by connecting to each unit individually and sending this command.
