USB 6353 Counter Triggering

[Eagle36]

I'm currently developing a VI which uses a trigger signal to specify a reference point which I need to use to synchronise an analogue input, which can use the trigger, and a digital counter, which doesn't have an option to do so nor will it take trigger blocks. Does anyone know if the USB 6353 supports counter triggering? It seems likely that it does not.

Thanks for any help you can give.

Actually, counter output tasks *can* be configured for a Start Trigger.  Counter input tasks can also be triggered, but not with the regular Start Trigger available through a call to DAQmx Trigger.vi 

What you need to do is use a DAQmx Trigger *property node*.  From there you can configure an "Arm Start Trigger" that will work for counter input tasks.

This has been a long-time source of confusion about counters.  Documentation about it exists, but it hasn't seemed to be prominent or easy to discover.  Here, I just tracked down a previous thread where I posted a couple useful links.   And you can find more info now that you know to search specifically for "Arm Start".
