Protocol specification The following three data forms is defined. COMMAND : The message sent to a system(AVR/AVC) from a controller(Touch Panel etc.) A command to a system is given from a controller. EVENT : The message sent to a controller(Touch Panel etc.) from a system(AVR/AVC) The result is sent, when a system is operated directly and a state changes. *The form of EVENT presupposes that it is the same as that of COMMAND. **Refer to the following table for the c
