Verifying Digital Counter Output in USB-6210

[rwpham]

Hello,

This is my first Labview project and have gotten stuck on something a little trivial that I can't find help for. I am currently counting digital edges on the Counter 0 Source. After counting n rising edges, I wish to output a TTL signal using the counter output.

I have two problems:

1) It seems I cannot output from counter 0 if I am accepting input from it at the same time. When I try to do so, it says "The specified resource is reserved. The operation could not be completed as specified." Wouldn't Input/Output be two different resources?

2) Instead, I am using the output from Counter 1. Is there a way that I can verify that I am indeed generating TTL pulses from this port at the correct time? At the moment I cannot wire up anything from the output port to physically verify it and was hoping there'd be a way through LabVIEW or NIMAX.

Thank you

1) How are you doing this in your code? What device do you have?

- If you are doing the Input/Output in the same task, then no your cannot do this. 

- Depending on the device, somethings you can wire the counter output to a PFI line and use that as a counter input.

2) Have you tried using MAX test panels for this?
