Using reference counter with 6602 board

[whatthehellamithinking]

I want to control a 6602 card in a Labview application so that I can count events in channels 1-6 depending on a reference counter in channel 0. I've set up channel 0 to count from a fixed value down to 0, and I am using hardware triggering to start all counters. Now I need something like a stop trigger to stop my event counters simultaneously when counter 0 reaches zero.

I tried to use counter 0 output as a gate for the others, but without success. Unfortunately, the help files for the TIO counter VI's are pretty lousy (nudge, nudge), so I'd be grateful if someone could give me a hint how to solve this problem.

Hi Sebastian (whatthehellamithinking),

Nice name 🙂 I think your idea about using counter 0 output as the gate signal is the right idea. However, I would make sure to configure a couple things. The first thing I would do is configure counter 0 output for toggle mode. This means when the counter rolls beyond zero it will toggle it's output. I would alsoe configure the output to be configured as high-to-low logic. Then I would connect it to the gate of all the other counters (make sure to configure a gate on each counter). The gate should initially be high on each counter since the output of counter zero should be high. Then when it rolls or reaches terminal count it will toggle the output which will gate each of the other counters.

Anyway, not sure i
f you tried it that way but I think it shoud work. Hope that helps. Have a good day.
