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.

Figure 4 shows the Multi-Cal-Test PCA card. The Multi-Cal-Test card contains a PGA308 with associated

electronics, jumpers for mode configuration, and a sensor emulator. The equivalent PGA309 test board

does not exist at the time of this writing; it is currently under development. The Multi-Cal-Test board can

be used to verify that the system is functional before connecting your sensor modules. The Multi-Cal-Test

PCA can also be used to demonstrate the accuracy capability of the system. The Multi-Cal-Test PCA is

also a good tool for learning how to use the system.

Overview

1.2 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.

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.

±15V Supply

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

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.

Loop or DUT Power Supply

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

Must allow for software control through RS-232 or IEEE488.

Suggested instrument is the Agilent 34401A.

Figure 9 illustrates how to connect the Multi-Cal-Interface cable to the Multi-Cal-Master PCA card. It is

important to make sure that the connector is not angled or crooked, and that the screws are fully

tightened. Improperly seated connectors are a common cause of intermittent unit failure.

Figure 9. Connect Multi-Cal-Interface Cable to Multi-Cal-Master PCA Card

Figure 10 shows how the Multi-Cal-Interface cable connects to the Multi-Cal-Interface PCA. Again, it is

important to make sure that the connector is not misaligned or crooked, and that the screws are fully

tightened. Improperly seated connectors are a common cause of intermittent device failure. Make sure

that you connect J1 of the Multi-Cal-Master PCA card to P1 of the Multi-Cal-Interface PCA card. When this

step is complete, repeat the process for the other connector (J0 and P0). It is a good idea to attach labels

to the cable connectors to indicate which connector it is associated with.

position, the PGA308 input signal is 3 mV.

LOW1 = 0 mV

LOW2 = 1 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.

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 27 shows the connection of the cables to the slave board. Make sure the cable is properly seated

and fully screwed down. Each slave board will have two interface cables. Each interface cable has four

channels.

Expanding the System Size

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

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.
