Hi Matt,
My name is Wayne, I am the Engineering Manager for Australian Monitor.
If you would like to PM me your email details, I can send you a much more detailed protocol document I completed recently for the AV Revolution. It includes parameter ID's of all DSP functions also. I will be releasing similar for the Zone Revolution also very soon.
I am keen to understand the platform your driver runs on, are you willing to tell me more about this?
Regards,
Wayne Osborn.
