"loopback" counter output without wiring

[GregFreeman]

I will be outputting a pulse on Trig0 line that resides on an AO card, based on that AO card's counter0. The problem I am having is that this AO card itself needs to trigger off this pulse. Is there any way I can do this without physically wiring up some sort of loopback and triggering off a different line for that card? I'm trying to minimize extra wiring if we can do this all internally. Also, I know a 6672 timing module card resolves this, but we're actually trying to figure out if we can do this without purchasing that extra card.

You can trigger off of the internal counter output on the AO card (the terminal would be called something like "/Dev1/Ctr0InternalOutput").  It's considered an "advanced" terminal so it doesn't show up in the drop down list of DAQmx terminals by default (which I find annoying I dislike this behavior ever so much).

Best Regards,

Thanks, I want to say I tried this but probably did something wrong. I have the advanced terminal's shown so it should be available. I'll take another look at it once I get my PXI chassis fixed (I think it was DOA...oh goody).
