    Table 2. Signal Descriptions
    Signal Reference Description
    AI GND

    Analog Input Ground—These terminals are the bias current return point for DIFF measurements. All ground references—AI GND, AO GND, and D GND—are connected on the device. Though AI GND, AO GND, and D GND are connected on the device, they are connected by small traces to reduce crosstalk between subsystems. Each ground has a slight difference in potential.

    AI <0..31>

    AI GND

    Analog Input Channels—AI 0+ and AI 0- are the positive and negative inputs of differential analog input channel 0.

    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. Though AI GND, AO GND, and D GND are connected on the device, they are connected by small traces to reduce crosstalk between subsystems. Each ground has a slight difference in potential.

    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, and D GND—are connected on the device. Though AI GND, AO GND, and D GND are connected on the device, they are connected by small traces to reduce crosstalk between subsystems. Each ground has a slight difference in potential.

    P0.<0..7>

    D GND

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

    APFI 0

    AI GND

    Analog Programmable Function Interface Channel—The APFI signal can be used as an analog trigger input. APFI 0 is referenced to AI GND when it is used as an analog trigger input.

    +5 V

    D GND

    +5 V Power Source—These terminals provide a fused +5 V power source.

    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.

    Reserved

    Reserved Pin—May be connected internally to device and... Should never be connected to any signal.
