    Table 2. Signal Descriptions
    Signal Reference Description
    AI GND

    Analog Input Ground—These terminals are the reference point for single-ended AI measurements in RSE mode and the bias current return point for DIFF measurements. All ground references—AI GND, AO GND, and D GND—are connected on the device.

    AI<0..15> Varies Analog Input Channels—For single-ended measurements, each signal is an analog input voltage channel. In RSE mode, AI GND is the reference for these signals. In NRSE mode, the reference for each AI Signal is an AI SENSE.

    For differential measurements, AI 0 and AI 8 are the positive and negative inputs of differential analog input channel 0. Similarly, the following signal pairs also form differential input channels: AI <1,9>, AI <2.,10>, and so on.

    AI SENSE Analog Input Sense—In NRSE mode, the reference for each AI <0..15> signal AI SENSE.
    AO <0,1> AO GND Analog Output Channels—These terminals supply voltage output.
    AO GND Analog Output Ground—AO GND is the reference for AO. All ground references—AI GND, AO GND, and D GND—are connected on the device.
    D GND Digital Ground—D GND supplies the reference for port 0, port 1 digital channels, PFI, and +5 V. All ground references—AI GND, AO GND, and D GND—are connected on the device.
    +5 V D GND +5 V Power Source—These terminals provide a +5 V power source or can be used to externally power the digital outputs.
    PFI<0..3>/P0.<0..3> D GND Programmable Function Interface or Static Digital Input Channels—Each PFI terminal can be used to supply an external source for AI, AO, or counter/timer inputs. You also can use these terminals as static digital input lines.
    PFI<4..7>/P1.<0..3> D GND Programmable Function Interface or Static Digital Output Channels—You can route many different internal AI, AO, or counter/timer output to each PFI terminal. You also can use these terminals as static digital output lines.
