How do I implement a stop trigger for my 6602 counters?

[rink]

I currently have the start of data acquistion for two channels syncrhonized with a start trigger. I am doing simple event counting using two seperate counters.

For my start trigger, I use a third counter to generate a single pulse and put the output on the trigger line that the two counters are watching.


Works great! But, I also want to synchronize the stopping of data acquisition for the two channels. I thought this would be simple as configuring a ND_STOP_TRIGGER like I did a ND_START_TRIGGER. But, this is giving me errors.


Does the 6602 not support stop triggering? Am I just out of luck?

Sorry I duplicated this post..was trying to put in the Counter/Timer discussion forum.

Hello;

The best way to accomplish that task is by configuring both counters to do 2 edges separation. By configuring that task, the counters will start counting at the event of the first pulse and will stop at the event of the second one.
There isn't such parameter as ND_STOP_TRIGGER, that is why you are getting that error.
You can find some examples showing how to do edge separation at NI's home page.
Hope this helps.
