•PFI <0..3>, PFI <8..11>
•ai/ReferenceTrigger
•ai/StartTrigger
•ai/SampleClock
•ai/ConvertClock
•ao/SampleClock
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.
