Introduction

is document describes the remote control protocol for controlling via the RS232/NET interface. e AV implements virtual IR commands in order

to simplify the protocol. Any operation that can be invoked using the IR remote control can be achieved over a control link using the Simulate RC5 IR

command (0x08). See page 7 for details of this command. e RC5 IR code set is listed from page 39.

Set-up

e AV must be correctly congured for Control; by default, Control is disabled for minimum standby power consumption. RS232 control can be

enabled using the front panel: press and hold the front panel DIRECT button for 4 seconds until “RS232 CONTROL ON” is displayed on the VFD.

 Any character in single quotes gives the ASCII equivalent of a hex value.

 <n> represents an unknown or variable number.
