PXI-6608 Pinout

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>

D GND

Programmable Function Interface—As an input, each PFI terminal can be used to route an external source for DO timing 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 Source—These pins provide +5 V power.

RESERVED

—

Reserved.

R GND

—

Restricted Ground—Tied to D GND. These terminals are routed to RESERVED when using the product with a SH68-68-D1 shielded cable or routed to D GND when using the product 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.
