    Table 2. Signal Descriptions
    Signal Reference Description

    AO <0..63>

    AO GND

    Analog Output Channels—These terminals supply voltage output.

    AO GND

    Analog Output Ground—AO GND is the reference for the AO channels. When AO GND is listed next to an analog signal name, it is the dedicated ground reference for the listed signals (for example, AO GND 2/3 is the ground reference for AO 2 and AO 3). All ground references—AO GND and D GND—are connected on the device. Though AO GND and D GND are connected on the device, they are connected by small traces to reduce crosstalk between subsystems. Each ground may have 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. When D GND is listed with a number, it is the dedicated ground reference for that PFI signal. All ground references—AO GND and D GND—are connected on the device. Though AO GND and D GND are connected on the device, they are connected by small traces to reduce crosstalk between subsystems. Each ground may have a slight difference in potential.

    P0.<0..3>

    D GND

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

    +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 AO, DI, and DO timing signals or counter/timer inputs. As a PFI output, you can route many different internal 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.

    NC

    No connect—Do not connect signals to this terminal.
