Notes:
■ Commands are used as notifications. If an amplifier is switched ON, it will notify the other devices on the control
bus by sending the Standby command (01). Any amplifiers with the same zone will take the notification as a
command and also switch ON.
■ When a command is sent to an amplifier it will first be transmitted on the control bus and then returned to the PC
(Home automation system). If an error occurs an error will be returned instead of the original command. The PC
(Home automation system) needs to ignore its command when it is returned.
