GPIB-RS232     National Instruments   Interface Terminal


GPIB-RS232 National Instruments

VSIG is the voltage difference between AI<0..7>+ and AI<0..7>-. This is the desired signal 

to be measured. VCM is the common-mode voltage with respect to the AI isolated ground, 

COM<0..7>, calculated by subtracting COM<0..7> from AI<0..7>-. VISO is the isolation voltage 

with respect to the chassis ground of the measurement device.

The analog input channels are floating with respect to chassis ground and each other. If you make 

a ground-referenced connection between the signal source and the PXIe-4310 input, make sure 

the voltage on the AI+, AI-, and COM connections are within the safety voltage limits to ensure 

safe operation. Refer to the PXIe-4310 Specifications for more information about Safety 

Voltages.

The COM terminal for each channel must be connected to the reference ground of the AI source. 

Failure to connect COM results in inaccurate measurements. You can connect the COM terminal 

directly to the negative terminal of the source as shown in Figure 2-2 or to an isolated ground of 

the source as long as the working voltage specification of the PXIe-4310 is not violated.

To ensure the specified EMC performance, wire the AI+ and AI- signals as twisted pairs and use 

the COM as a shield. The COM connection should be made as close to the source as possible to 

take advantage of the differential nature of this device.
