I recently bought this receiver and it has an RS232 serial interface connection on the rear panel. There is no info on this interface in the manual and according to Yamaha, it is only used by professional installers.
Can anyone tell me something about this interface? Where can I get software to talk to my receiver? What can I control with it?
I know some of you audiophiles out there have this receiver. Don't tell me you just let it sit there and collect dust....
