I have a project going on where we are using a MX-900i with a MRF-350i to send IR commands to a Crestron DMPS-300-C via it's IR in which will trigger functions in the Crestron program. I have the Crestron portion all set and I think I have the grasp of how the macros for the buttons are created on the URC remote.

The one thing I can't figure out is how do I add new devices to the IR database? Is it possible to creature a IR driver for the URC database manually by typing in the hex values?

Thank you.
