Exporting Timing Output Signals Using PFI Terminals

You can route any of the following timing signals to any PFI <6..9>
terminal.

Note Short pulses on the signal might not be observable by the user or another instrument.
Refer to the Digital Output (Port 1) section of the NI 6238/6239 Specifications for more
information.

Using PFI Terminals as Static Digital Inputs and Outputs

When a terminal is used as a static digital input or output, it is called P0.x
or P1.x. On the I/O connector, each terminal is labeled PFI x/P0.x or
PFI x/P1.x.

Connecting PFI Input Signals

All PFI input connections are referenced to P0.GND. Figure 8-3 shows this
reference, and how to connect an external PFI 0 source and an external
PFI 2 source to two PFI terminals.
