How do I convert Traditional DAQ Trigger configurations that uses "I/O connector" input to DAQmx?

I am converting a lot of old Traditional DAQ code to DAQmx, and the digital write is configured to trigger on "I/O connector" with the trigger condition "Rising Edge". I'm not sure how to convert this to DAQmx (or exactly what it means). There seems to be nothing exactly like it in DAQmx.

Hi Laurel,

 

Here is a list of documents you will find most useful making this transition:

This VI should do what you would like.  You will jsut need to specify where you are bringing in the trigger; this will be a PFI line most likely (PFI0) rather than the IO Connector.
