I'm interested in a TRC-780 and a MRX-10 for a custom install, but need the ability to use a completely custom two-way protocol with it as it is supposed to integrate with a customer's existing HA system. Is this possible with the MRX-10 and TRC-780 combo?

Some requirements:
1. Customer wants complete two-way capability. This means macros would trigger ascii text for each button press. This ascii text would then be sent over ethernet using a predetermined port. Basically if the ascii text from a button press can show up in a telnet client (e.g. over a tcp socket port), it will work fine.

2. The ability to send status messages over IP from the HA system to the remote's display. This would be for status of what's playing, alarm status following an alarm status change, weather etc...

Thanks in advance!
