These are the connector drawings only. [. . . ] All values in this document are in Decimal. All commands will follow the format: <Header><Command Identifier><Argument 1><Argument 2><Argument 3> where: <Header> = <254><241> <Command identifier> = <byte> <Argument 1> = <byte> <Argument 2> = <byte> <Argument 3> = <byte> Each command will be able to access the system configuration directly, eliminating the need to press any button on the Generation VIII's front panel.
Examples: 1) To put the Generation VIII into standby: Send 254, 241, 04, 14, 01, 00 (all values in decimal). Where 254 and 241 are the header, 04 = Command_Do Action, 14 = Action_Power Main, 01 = put unit into standby, and 00 = filler (4 characters required). 2) To change to Input # 2: Send 254, 241, 01, 04, 00, 02 Where 254 and 241 are the header, 01 = Command_Variable_Change, 04 = Variable_Input_Selected, 00 = filler (4 characters required), and 02 = Input 2. -OR254, 241, 04, 05, 02, 00 Where 254 and 241 are the header, 04 = Command_Do Action, 05 = Select Input, 02 = Input 2, and 00 = filler (4 characters required. 3) To increment the Master Volume: Send 254, 241, 04, 20, 00, 00 Where 254 and 241 are the header, 04 = Command_Do Action, 20 = Action_Variable Specified Increment, 00 = Variable_Master Volume, and 00 = filler (4 characters required)
