I have a 6682 timing board.
i know how to generate a clock on any terminal (pxi_trig0,1 etc).
how do i connect that clock to the time source of a timed loop ?
thanks.

The following links should be of use to you:

It all revolves around DAQmx Create Timing Source. The help files for the polymorphic instances are worth reading to determine which method you want to use.

I thought that DaqMX create timing source would help,
but it doesn't.
any of the polymorphic instances didn't match my need.
i created a clock that goes from my 6682 timing board at PFI1 terminal.
there is only one polymorphic instance of "DaqMX create timing source" that let me choose source terninal,
but it also wants me to choose counter.
any idea ?

Hi,
The PXI-6682 is an NI-Sync device not a DAQmx one. You may be able to route signals from the PXI-6682 to a DAQmx device and use the DAQmx Create Timing Source.vi. You could also try using NI-TimeSync with the NI-Sync plugin. This will allow you to synchronize LabVIEW RT system time to the current time reference of the PXI-6682 (see link below for more details).
