You can configure channels of a parallel digital module as Programmable Function Interface (PFI) terminals. The cDAQ chassis also provides one terminal for PFI. Up to two digital modules can be used to access PFI terminals in a single chassis.

You can configure each PFI individually as the following:

  • Timing input signal for AI, AO, DI, DO, or counter/timer functions
  • Timing output signal from AI, AO, DI, DO, or counter/timer functions
