Overview
The Multi-Cal-System Evaluation Module is a set of EVMs that is used to calibrate multiple PGA308 and
PGA309 sensor modules. The PGA308 and PGA309 are two programmable analog sensor signal
conditioners. All components in the Multi-Cal-System can be expanded to calibrate up to 64 sensors
simultaneously. For a more detailed description of the PGA308, please refer to the product data sheet
(SBOS440) available from the Texas Instruments web site at http://www.ti.com. Additional support
documents are listed in the section of this guide entitled Related Documentation from Texas Instruments .
The Multi-Cal-System Evaluation Module consists of two printed circuit boards (PCBs). One board (the
USB DAQ Platform) generates the signals required to communicate with the Multi-Cal-System, which is
the second board (Multi-Cal-Master PCA), as well as support and configuration circuitry. The complete
Multi-Cal-System contains a series of PCBs, and can be expanded to meet your specific system
requirements.
Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with
the Multi-Cal-System Evaluation Module.

Figure 2 shows the Multi-Cal-Slave kit. Each Multi-Cal-Slave kit enables you to expand the system by
eight channels. For example, a Multi-Cal-Master kit and one Multi-Cal-Slave kit combine to form a
16-channel system. Seven Multi-Cal-Slave boards and a single Multi-Cal-Master combine to form a
64-channel system.
Slave Ribbon Cable
Multi-Cal-Slave PCA
Figure 2. Multi-Cal-Slave Kit
The Multi-Cal-Slave kit contains these items:
• Multi-Cal-Slave PCB: The slave board adds eight measurement channels to the system. The slave
board is almost identical to the master board. The primary difference between the master and the slave
is that the master connects to the USB DAQ Platform and the slave connects to the master via a
ribbon cable, as shown in Figure 2.
• Slave Ribbon cable: The Slave Ribbon cable connects all the signals and power from the master to
the slave. Note that power is distributed across several wires to minimize loss.
Figure 3 shows the Multi-Cal-Interface PCA card. The Multi-Cal-Interface can be used to connect the
sensor modules to the system. The Multi-Cal-Test boards can also be connected to this board. The
Multi-Cal-Interface board connects to the master or slave via the Multi-Cal-Interface cable on the 37-pin
DSUB connectors.

Recommended Starter System
The Multi-Cal-System starter system is an eight-channel system for calibrating PGA308 and PGA309
sensor modules automatically. The starter system allows you to verify that the Multi-Cal-System meets
your specific application requirements. You can expand the capacity of your system later by adding slave
boards. Each slave board adds another eight channels, for a maximum system capability of 64 channels
(one master and seven slave boards). Table 1 describes the recommended starter system and lists the
quantities of each board required.

Depending on the mechanical requirements of
your specific system, you may develop your
own interface board.
Two Multi-Cal-Test EVMs allow you to check
two channels. This option is typically enough
for initial evaluation of the system. Eight units
would allow you to fully test all eight channels
of the starter system.
The Multi-Cal-Test EVM board uses the PGA308. The equivalent PGA309 test board does not exist at
the time of this writing; it is currently under development.
There are also several additional pieces of test equipment required; Table 2 summarizes this equipment.
Table 2. Additional Test Equipment Required

±15V Supply
This is power for the multiplexers on the Multi-Cal-Master board. This
supply can range from ±12 V to ±16 V. Choose a low-noise linear
supply for best performance. This supply also powers slave boards if
you expand the system in the future. Keep in mind the current output
capability.
Current requirement for Master = 150 mA
Current for each Slave = 150 mA
Example: For eight channels and one master = 150 mA
Example: For 64 channels (one master and seven slaves) = 8 x 150
mA = 1.2 A
Loop or DUT Power Supply
This supply can range from 5V to 40V, depending on your sensor
module requirements. This power will be directly connected to the
sensor modules. Choose a low-noise linear supply for best
performance. Keep in mind the current output capability. All sensor
modules are powered simultaneously, so multiply the number of
channels by the expected device current to determine the
requirements.
Example: For eight current loop modules: Assume that maximum
current = 25mA (overcurrent range); 8 x 25 mA = 20 0mA
Example: For 64 current loop modules: 64 x 25 mA = 1.6 A
Precision Digital Multimeter
Must allow for software control through RS-232 or IEEE488.
Suggested instrument is the Agilent 34401A.
This controller is not required if you are using RS-232 control. This
item is a National Instruments IEEE488 controller. It allows you to
connect your computer to the precision multimeter for automatic
control.

Place the jumper shorting unit on one of these five
positions. This jumper bank determines the
sensor-emulator output when the switch (SW1) is in the
HIGH position. The output of the sensor emulator is the
input to the PGA308.
For example, when the shorting unit is in the HIGH2
position, the PGA308 input signal is 3 mV.
LOW1 = 0 mV
LOW2 = 1 mV
LOW3 = 6 mV
LOW4 = 30 mV
LOW5 = 81 mV
Place the jumper shorting unit on one of these five
positions. This jumper bank determines the
sensor-emulator output when the switch (SW1) is in the
LOW position. The output of the sensor emulator is the
input to the PGA308.
For example, when the shorting unit is in the LOW3
position, the PGA308 input signal is 6 mV.
Figure 13 shows how to connect the Multi-Cal-Test PCA to the Multi-Cal-Interface PCA. The
Multi-Cal-Test PCA demonstrates the capability of the Multi-Cal-System. You can test the accuracy and
repeatability of programmed modules using the Multi-Cal-Test PCA. The Multi-Cal-Test PCA is also
helpful in learning how to use the system. Another purpose for the Multi-Cal-Test PCA is to verify that your
system is fully functional before testing your product.

Expanding the System Size
The Multi-Cal-System can be expanded by adding Multi-Cal-Slave boards. Each Multi-Cal-Slave board
adds eight additional channels. The maximum system size is 64 channels (one master and seven slaves).
The first step in expanding the system size is to remove the 0.25-inch standoffs and replace them with
1.25-inch standoffs; this step is shown in Figure 23.

The next step in expanding the physical system size is to connect the slave ribbon cable to the master;
this step is illustrated in Figure 24. Make sure to match the key on the ribbon cable with the notch in the
connector.

Figure 28 shows the jumpers on the Multi-Cal-Slave board that identify the board location. The jumpers on
each slave board must be in a unique position. For the first slave board connected, set the jumpers in the
Slave1a and Slave1b position. As you add additional boards, increment the jumper position. For example,
on the second board connected, use the Slave2a and Slave2b position.
Place jumpers on Slave
in the Slave1a and Slave1b
positions
Figure 28. Jumper Locations and Positions for Expanding System Size
The final step to expanding the system is to connect the interface-cables from the slave to an interface
board. Figure 29 shows the complete system connection for a 16-channel system (that is, one master and
one slave).

Troubleshooting Tips
The most common issues that can occur with the Multi-Cal-System are communication problems.
Figure 30 shows the message that occurs if you have a communications problem. If you get this message,
use the Windows Device Manager to check the status of the USB-DIG-Platform.
Figure 30. Communications Error Message
Figure 31 shows the Windows Device Manager and the active connection for a USB-driven human
interface device. When you plug and unplug the USB cable, you can see the device appear and disappear
from the list. Select your device and review the details. It should show up as a Human Interface Device
with PID = 2F90, 2F91, 2F92, or 2F93. If it appears as a good USB device, but is not a human interface
device, then the firmware was not programmed properly.
You can also see in the Windows Device Manager the USB Human Interface Device
that corresponds to the USB-DIG Platform. Note the address is: PID = 2F90.

warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
