Counter n Aux Signal
The Counter n Aux signal indicates the first edge in a two-signal
edge-separation measurement.
Routing a Signal to Counter n Aux
Each counter has independent input selectors for the Counter n Aux signal.
Any of the following signals can be routed to the Counter n Aux input.
•RTSI<0..7>
• PFI <0..15>
• ai/ReferenceTrigger
• ai/StartTrigger
•PXI_STAR
• Analog Comparison Event
In addition, Counter 1 Internal Output, Counter 1 Gate, Counter 1 Source,
or Counter 0 Gate can be routed to Counter 0 Aux. Counter 0 Internal
Output, Counter 0 Gate, Counter 0 Source, or Counter 1 Gate can be routed
to Counter 1 Aux.
Some of these options may not be available in some driver software.
Counter n A, Counter n B, and Counter n Z Signals
Counter n B can control the direction of counting in edge counting
applications. Use the A, B, and Z inputs to each counter when measuring
quadrature encoders or measuring two pulse encoders.
Routing Signals to A, B, and Z Counter Inputs
Each counter has independent input selectors for each of the A, B, and
Z inputs. Any of the following signals can be routed to each input.
•RTSI<0..7>
• PFI <0..15>
•PXI_STAR
• Analog Comparison Event
Routing Counter n Z Signal to an Output Terminal
You can route Counter n Z out to RTSI <0..7>.
