Refer toAppendix A, Device-Specific Information, for device I/O connectorpinouts.I/O Connector Signal DescriptionsTable 3-1 describes the signals found on the I/O connectors. Not all signalsare available on all devices.Table 3-1. I/O Connector SignalsSignal Name Reference Direction DescriptionAI GND — — Analog Input Ground—These terminals are the input biascurrent return point. AI GND and AO GND are connected onthe device.Note: AI GND and AO GND are isolated from earth ground,chassis ground, P0.GND, and P1.GND.AI <0..15> AI GND Input Analog Input Channels 0 to 15—For single-endedmeasurements, each signal is an analog input voltage channel.In RSE mode, AI GND is the reference for these signals.For differential measurements, AI 0 and AI 8 are the positiveand negative inputs of differential analog input channel 0.Similarly, the following signal pairs also form differentialinput channels:, , , ,, , Also refer to the Analog Input Ground-Reference Settingssection of Chapter 4, Analog Input.Note: AI <0..15> are isolated from earth ground and chassisground.AO <0..1> AO GND Output Analog Output Channels 0 to 1—These terminals supply thevoltage output of AO channels 0 to 1.Note: AO <0..1> are isolated from earth ground and chassisground.
