I am using a T2+ with RP6 and trying to use serial commands to control a russound CAV 6.6. Russound has not provided much help for the RS-232 settings specifically, the baud, data bits, stop bits, etc. I have the HEX command document but there is no reference in it for what the settings need to be. I've tried dozens of combinations with no luck and have other serial devices on my RP6 that work just fine. Anybody have any experience with this combination?
