JP1 Remotes

I would appreciate any suggestions...

My AMP's remote uses the JVC protocol for some of its buttons, and the JVC-48 protocol for others. In addition, some of the buttons using the JVC protocol use different device codes.

Is there a way to handle this remote with a single upgrade to my URC-9910 without using many keymoves?

My guess is that it may be sending out commands to turn on other JVC gear. If you go to DVD input for example, it not only sets it's input but turns on the JVC DVD player, too. IIRC, that's the only time we have seen the JVC-48 protocol. The point being that you may not need the JVC-48 protocol to make the receiver work. You might try the built in setup code for JVC receivers and try the numerals. Those are the discrete inputs.

The answer to your question is that yes there are several ways to combine all those into one device upgrade. The simplest is to key move the other commands to the device you are using for the receiver.
