Connecting Timing Signals - National Instruments NI 6711 User Manual

Note The Master Timebase signal can only be accepted as an external signal over RTSI.
For more information on the Master Timebase signal, refer to the

Many of these timing signals are also available as outputs on the PFI pins.
(RTSI), for information on routing this signal.
The 10 programmable function interface (PFI) pins labeled PFI <0..9>
route all external control over the timing of the device. These lines serve as
connections to virtually all internal timing signals. These PFIs are
bidirectional. As outputs they are not programmable and reflect the state of
many waveform generation and counter timing signals. There are five other
dedicated outputs for the remainder of the timing signals. As inputs, the PFI
signals are programmable and can control all timing signals.
All digital timing connections are referenced to D GND. Figure 7-2 shows
this reference, and how to connect an external PFI 0 source and an external
PFI 2 source to two PFI pins.
