I did pick up a null modem cable, so I do have that. =)
I ended up wiring everything in. None of the codes are working, but that didn't surprise me since the Pwr hex wasn't working.

If you are open to sharing a file, I would take you up on it in a heartbeat. As I mentioned, the RS-232 is new to me... Everything I run is pretty much IR linked to the MSC-400.

Since I would run the Matrix from a closet, I assume I would need to pick up a MSC-400 RS232F cable to run this. Correct?
