    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>


    Analog Input ChannelsFor 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.


    Analog Input SenseIn NRSE mode, the reference for each AI <0..15> signal is AI SENSE.

    AO <0,1>

    AO GND

    Analog Output Channels—These terminals supply voltage output.

    AO GND

    Analog Output GroundAO GND is the reference for AO. All ground references—AI GND, AO GND, and D GND—are connected on the device.

    D GND

    Digital GroundD GND supplies the reference for port 0, port 1, port 2 digital channels, PFI, and +5 V. All ground references—AI GND, AO GND, 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.


    D GND

    Port 0 Digital I/O ChannelsYou can configure each signal individually as an input or output.

    PFI <0..7>/P1.<0..7>, PFI <8..15>/P2.<0..7>

    D GND

    Programmable Function Interface or Digital I/O Channels—Each of these terminals can be individually configured as a PFI terminal or a digital I/O terminal.

    As an input, each PFI terminal can be used to supply an external source for AI, AO, DI, and DO timing signals or counter/timer inputs. As a PFI output, you can route many different internal AI, AO, DI, or DO timing signals to each PFI terminal. You can also route the counter/timer outputs to each PFI terminal. As a port 1 or port 2 digital I/O signal, you can individually configure each signal as an input or output.


    No connect—Do not connect signals to this terminal.
