Page 2: Protocol Specification
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. - Page 3 The example of a command * <CR> is the meaning of 0x0D. SIDVD<CR> : Select Input source DVD MSTHX SURROUND EX<CR> : surround Mode Set to THX SURROUND EX MVUP<CR> : Master Volume UP PWON<CR> : system PoWer ON PWSTANDBY<CR> : system PoWer STANDBY SI?<CR>...
- Page 4 Others A) COMMAND is receivable also during transmission of EVENT. B) Since CHANNEL VOLUME changes simultaneously when the SURROUND MODE changes, the value of the channel volume of all channels returns as EVENT. C) CHANNEL VOLUME returns the data of ALL channels by the present SURROUND MODE also including an intact channel. In this case, the data of an intact channel is set to "50".
