Counter Output with NI cDAQ 9188

[Ahmed.TUN]

I am trying to generate pulses with the counters included in the NI 9188 cDAQ chassis.

I tried first to do that with NI 9411 module but this task didn't figure out in MAX.

I'm trying now to perform that with the PFI 0 BNC connexion in the chassis but that still doesn't exist in max

what should I do?

The 9411 is an input module so can't be used to generate pulses.

You can use the BNC connectors on the 9188 chassis to route the counter outputs--however, MAX does not provide that functionality.  To program the counter output to issue pulses to the chassis PFI line using the DAQmx API you would need to do something like this:

Other development environments have similar APIs; the trick here is to use <chassis_name>/_ctr0 to refer to the internal counter without having to go through a module.
