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?

For better or faster answer, I'd recommend you post this question to the Counter/Timer Forum.
Good luck,

One option you may want to consider is using the third counter to Gate the two counters that are doing event counting. (Not simple event counting.) When the signal on the Gate is high, the counters will count the pulses on the Source, then when the signal on the Gate goes low, the counters will stop counting. This may work for your application if you know how long you need to count.

Let me know if this will not work and I may be able to think of another solution.
