Routing Counter n Source to an Output Terminal

You can route Counter n Source out to any PFI <0..15> or RTSI <0..7>
terminal. All PFIs are set to high-impedance at startup.
The Counter n Gate signal can perform many different operations
depending on the application including starting and stopping the counter,
and saving the counter contents.

Routing a Signal to Counter n Gate

Each counter has independent input selectors for the Counter n Gate signal.
Any of the following signals can be routed to the Counter n Gate input.
• RTSI <0..7>
• PFI <0..15>
• ai/ReferenceTrigger
• ai/StartTrigger
• ai/SampleClock
• ai/ConvertClock
• ao/SampleClock
• di/SampleClock
• do/SampleClock
• PXI_STAR
• Change Detection Event
• Analog Comparison Event
In addition, Counter 1 Internal Output or Counter 1 Source can be routed to
Counter 0 Gate. Counter 0 Internal Output or Counter 0 Source can be
routed to Counter 1 Gate.
Some of these options may not be available in some driver software.
