DAQmx: Switching input terminal for running counter task

[gustav]

I'm running a counter task for pulse generation, using an external signal as a source for ticks. I'm wondering if it's possible to switch the input terminal for the ticks while the task is running?

This means I would have two sources of pulses connected to two different pins on my NI6602 card, and while the pulse generation task is running I want to be able to switch from which pin it gets the ticks. When I try to do this I get an error, so it appears to me it is not possible. However I thought I should check with the expert before ruling out the possibility, or perhaps someone could tell me another way to accomplish what I need . Any answers would be apreciated.

Your right.. once the task is started, you can't switch pins mid-stride.

Thanks for confirming my suspicisons ! Will have to think of another solution then.
