Many of the URC Orion's button have stopped working so I bought a Harmony Elite, and I am trying to learn it. It does not seem to have many of the discretes I used on my previous remote. I see referenced a Harmony database, but when I go to their web site, I can't find anything about discrete codes. I have a Yamaha Adventage RX-A2000 and use discretes for HDMI output and Party on off mode. Is there a way to use them with the Harmony? My Orion is set up to only send RF and the serial cable is no longer recognized my the Orion so I can't change it. I tried sending a training code via an IR blaster attached to the hub of the Orion, but the Elite wouldn't accept it.
