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. 1.1 Multi-Cal-System Hardware Options Figure 1 shows the hardware included with the basic Multi-Cal-System kit. Contact the factory if any component is missing. Universal Power Supply USB DAQ Platform USB Cable Multi-Cal-Master PCA Figure 1.

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.

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. Table 1. Recommended Starter System Quantity Name 1 Multi-Cal-Master EVM This basic board gives you eight channels. Multi-Cal-Interface cable You may choose to build your own cable because of cable length requirements. The construction of the cable is given in the Multi-Cal System Cable user's guide (SBOU092). 1 Multi-Cal-Power cable You may choose to build your own cable because of cable length requirements. The construction of the cable is given in the Multi-Cal System Cable user's guide (SBOU092). 1 Multi-Cal-Interface EVM 2 2 (1) Multi-Cal-Test EVM Comments (1) 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 Name Comments ±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.

The Multi-Cal-Test PCA has seven jumpers that allow you to choose between three different modes of operation (current output, four-wire voltage output, and three-wire voltage output). The Multi-Cal-Test PCA card also has two banks of jumpers that select the sensor-emulator output on the test board. SensorEmulator switch (SW1). Selects between High bank and Low bank. Here, Low bank is selected. Seven jumpers used to select the PGA308 mode. Here, 4-wire Voltage Output is selected. Jumper banks for sensor emulator. Select one of the five positions for each bank. Here. Low = 6mV, High = 3mV. Figure 12. Jumpers on Multi-Cal-Test PCA Card Table 3 and Table 4 explain how to set the jumpers on the Multi-Cal-Test PCA and the respective jumper functions. The test board allows all for the operation of the three modes of the PGA308 device. The test board also has a jumper-selected sensor-emulator. The sensor-emulator creates an input signal for the PGA308 so that you can perform an example calibration. Table 3.

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.

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. Figure 31.

FCC Warning This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15 of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this equipment in other environments may cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may be required to correct this interference. EVM Warnings and Restrictions It is important to operate this EVM within the input voltage range of 5.7V to 9V and the output voltage range of 0V to 5V. Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions concerning the input range, please contact a TI field representative prior to connecting the input power. Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than +25°C. The EVM is designed to operate properly with certain components above +25°C as long as the input and output ranges are maintained. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation, please be aware that these devices may be very warm to the touch.
