Hardware Timed Output with cDAQ 9172 and NI 9401

[d-s-m]

I am using a NI 9401 in a cDAQ 9172 chassis and want to output a hardware timed pulse pattern. My understanding is that I must use the internal counter of the cDAQ 9172 as sample clock for the digtial output. But I don't know, which channel I have to use.

Hi d-s-m,

please have a look these documents:

Which cDAQ Modules can be used to Access the On-board Counters?

I'm trying to do this. Do any code examples exist? Note: I would prefer 2009SP1 or earlier if something preexists.
