Trying to trace inputs to physical modules

Hello all,

I recently was assigned to a project that had some LabVIEW code already set up, along with the physical system the code is meant to be controlling.  The system uses 3 NI cards, NI 9221, NI 9474, and NI 9422 :

My problem is that looking at the LabVIEW code itself, all of the I/O names are variations on cDAQ2ModX/portY/lineZ.  It's been years since I've used LabVIEW, and I'm having trouble findings a way that I can tell to determine which cards are sending and recieving which signals from which channels.  Is there a way to dig into the code to determine this that I'm missing or have forgotten?
