Hi guys & girls,
I'm trying to get hold of a definitive RS-232 protocol for this Yamaha Amp.
I have the RX-Z1 protocol from:
[Link: yamaha.com] but there is some serious differences between this and the AZ2. Although I have taken the Z1 and tweaked them a bit and got quite a bit to work on the AZ2, the amp is at the client's and it is just not cool to sit there tweaking and hoping.
Two issues I'd really like to address are the input select commands and the DSP program commands.
This is to interface to Crestron.
Thanks for your help.
Regards
