We're in the same boat.? My Salesman has a C52 Preamp which is a similar protocol is unable to find serial control in the Crestron Home database.? Seems like the only supported model they have is really just a Marantz protocol.? We submitted a request with TB support and have been told to pay a developer to create a driver for us for thousands of dollars.? I ended up having to create an IR driver for him for the time being.
