Counters
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.
Routing Counter n Source to an Output Terminal
You can route Counter n Source out to any PFI terminal.
Counter n Gate Signal
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:
•
Any PFI terminal
•
AI Reference Trigger
•
AI Start Trigger
•
AO Sample Clock
•
DI Sample Clock
•
DI Reference Trigger
•
DO Sample Clock
•
Change Detection Event
•
Analog Comparison Event
In addition, a counter's Internal Output or Source can be routed to a different counter's gate.
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.
