17 RS232 Protocol —Continued 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 co...

19 RS232 Protocol —Continued Keypad Key Codes An Integra Keypad may be directed to emit its learnt IR commands via RS232 control. This is achieved by sending a ‘Cause key press on Keypad’ command “0B” followed by the zone, and the Keypad key code (data).The Keypad key code is encoded with IR string ...
