Actually, I still haven't got it straight.
I read here that the purpose of this remote is to be a zone remote. Note that whenever I say "zone" from here out, I do not mean the main zone, but, for instance, a small system in a bedroom.
As such, I expect (that is the same as "assume" and thus completely subject to error) that it will be able to emit IR signals in the zone, while also using RF to communicate with the MRX10 for commands that involve the system.
You say it's "completely useless without an MRX10 to tell it what to do." That says to me that it does not emit IR but instead, somehow, when in a zone, must send a signal to the MRX10, which sends a signal back to it to tell it "that's a command for the amp in front of you, so emit some IR." Otherwise, it's a zone remote but the MRX10 must be wired to the zone so that IR signals can come from the MRX10 to that room.
Or something else. How does this work?
The TRC780 does not send IR signals out of it. it sends and receives data via RF to the MRX10. All the programming for the system is done in the MRX10.
The TRC780 does have a built in IR output, but as of now, you cannot use it. I do suspect that one day they will enable the IR output in the TRC780. They are supposed to be releasing small room control boxes that you can mount behind a TV to control the TV without running more wires.
you are a URC dealer, take an online training class or sign up for a webinar, it helped me understand the differences, it should help you too.
