There is eth cat 5 and cat 7 in all zones. And there is no IR emitter wires.
In all zones are tv and sound bar (maybe something additional). in cabinet all sources (Dune HD Max, dune tv-301, Sat reciever, bose lifestyle v35,apple tv). Harmony is more interesting because of easy setup.
What about this?

Can the URC MX-5000 work with MRF-350 and MRF-260 at the same time?
Has the MX-5000 IR?
