The stock driver just shows tx 1-6 and rx 1-6. I always create a new driver from scratch with the names of the sources for the TX and room names for the RX. Makes building macros MUCH MUCH easier. Can be tedious without it. I also add commands for OSD pop ups, again, very tedious. I foresee a day when this is automated and pulls all the info from the controller. It IS possible and should be done (no OSD info in controller, but that too needs redone, some sort of TCM driver, that makes this process MUCH easier). This is regarding URC, not sure how it works on other control systems.
