    Signal Reference Description

    PFI <0..31>/P0.<0..31>

    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 DO timing signals or counter/timer edge or level polarity selection. As a PFI output, you can route many different internal DI or DO timing signals to each PFI terminal. You can also route certain counter/timer outputs to PFI <24..31> terminals.. As a port 0 digital I/O signal, you can individually configure each signal as an input or output.

    PFI <32..39>/P1.<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 route an external source for DO timing signals or counter/timer edge or level polarity selection. As a PFI output, you can route many different internal DI or DO timing signals to each PFI terminal. You can also route certain counter/timer outputs to these terminals.

    +5 V

    D GND

    +5 V Power SourceThese pins provide +5 V power.

    RESERVED

    Reserved—Do not use these terminals. They are weakly pulled down to D GND.

    R GND

    Restricted Ground—These terminals are not connected to ground when using the product with a SH68-68-D1 shielded cable or routed to D GND when using the device with a R6868 ribbon cable.

    D GND

    Digital Ground—These terminals supply the reference for the PFI and digital signals at the I/O connector and the +5 VDC supply.
