The selected edge of the Counter n Source signal increments and decrements the counter value depending on the application the counter is performing. The following table lists how this terminal is used in various applications.
|Application||Purpose of Source Terminal|
|Pulse Generation||Counter Timebase|
|One Counter Time Measurements||Counter Timebase|
|Two Counter Time Measurements||Input Terminal|
|Non-Buffered Edge Counting||Input Terminal|
|Buffered Edge Counting||Input Terminal|
|Two-Edge Separation||Counter Timebase|
In addition, TC or Gate from a counter can be routed to a different counter source.
Some of these options may not be available in some driver software. Refer to the Device Routing in MAX topic in the NI-DAQmx Help or the LabVIEW Help for more information about available routing options.
You can route Counter n Source out to any PFI terminal.
