The Sherwood protocol looks virtually identical to the Outlaw protocol document, with the exception that the Sherwood document contains additional codes for controlling the surround modes. I have no idea what effect, if any, sending these codes to the Outlaw would have! My guess is that the Outlaw software is sufficiently different from the Sherwood that the codes would have no effect.
I can email you a copy of the the Sherwood document if you're interested.
