Communication between the remote controller (RC) and the AV takes the form of sequences of bytes, with all commands and responses having the same basic format. The AV shall always respond to a received command, but may also send messages at other times. Each transmission by the RC is the following format:

„ „ St (Start transmission): 0x21 ‘!’ „ „ Zn (Zone number): see below. „ „ Cc (Command code): the code for the command „ „ Dl (Data length): the number of data items following this item,excluding the ETR „ „ Data: the parameters for the command „ „ Et (End transmission): 0x0D Each response by the AVR is the following format::

„ „ St (Start transmission): 0x21 ‘!’ „ „ Zn (Zone number): see below. „ „ Cc (Command code): the code for the command „ „ Ac (Answer code): see below. „ „ Dl (Data Length): the number of data items following this item, excluding the ETR „ „ Data: the parameters for the response of length n. n is limited to 255. „ „ Et (End transmission): 0x0D The AV responds to each command from the RC within three seconds. The RC may send further commands before a previous command response has been received. Controlling via RS232/NET Introduction This document describes the remote control protocol for controlling via the RS232/NET interface. The 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. The RC5 IR code set is listed from page 26. Set-up The AV must be correctly configured 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. Alternatively, Control for RS232 or IP can be enabled using the OSD menu. Press A followed by U on the remote control in order to access the setup menu. Use the cursor keys < > , ' and O to enter the General Setup menu and locate the option Control. Press O, , then O to change this parameter to ‘On’. IP control is via port 50000 of the IP address of the unit (in the Network Settings menu).

Serial Cable Specification

The AV shall be fully compatible with AMX Duet™ Dynamic Device Discovery Protocol (DDDP) The following description of Dynamic Device Discovery comes from the AMX website (www.amx.com). Dynamic Device Discovery is part of AMX’s Duet™ platform, which combines the proven reliability and power of NetLinx with the extensive capabilities of the Java 2 Micro Edition (J2ME) platform. When integrating a serial or IP device from a manufacturer embedding the Dynamic Device Discovery Protocol (DDDP), Duet recognizes the device and loads the appropriate Duet module, which automatically installs the new device. AMX’s NetLinx Master can then find and install the Duet device module either from a library on the master, from AMX’s Web site, or from the manufacturer’s Web site. Duet also allows for device swapping so that programming changes are not required when devices with DDDP are removed or replaced – a huge benefit for end users. The Duet platform is an extension AMX’s InConcert® manufacturer partner program, which was developed to ensure seamless communication between partners’ devices and the AMX control system. Data is specified in the ASCII format. All ASCII characters between the quotes “” should be recognised/transmitted. “\r” is a carriage return (0x0D) Command: “AMX\r” MC-10 Response: “AMXB\r” RV-9 Response: “AMXB\r” RV-6 Response: “AMXB\r” Where x.y.z = RS232 protocol version number. Zone numbers The following zone numbers are defined: „ „ 0x01 – Zone number 1. (Zone 1 is the master zone. Commands that appear zone-less refer to the master zone) „ „ 0x02 – Zone number 2. Answer codes The following answer codes are defined: „ „ 0x00 – Status update. „ „ 0x82 – Zone Invalid. „ „ 0x83 – Command not recognised. „ „ 0x84 – Parameter not recognised. „ „ 0x85 – Command invalid at this time.¹ „ „ 0x86 – Invalid data length. ¹Certain commands cannot be processed when the Setup Menu is being displayed. An answer code of 0x85 will be returned in these circumstances. Also, commands for tuner control cannot be processed when the tuner input is not selected, etc. State changes as a result of other inputs It is possible that the state of the AV may be changed as a result of user input via the front panel buttons or via the IR remote control. Any change resulting from these inputs is relayed to the RC using the appropriate message type. For example, if the user changed the front panel display brightness using the DISPLAY button on the front panel, a display message (defined below) would be sent to the RC. A similar action would be taken for all other state changes (including decode mode changes). Reserved Commands Commands 0xF0 to 0xFF (inclusive) are reserved for test functions and should never be used. Example command and response sequence As an example, the command to simulate the RC5 command “16-16”, volume up: STR ZONE CC DL Data 1 Data 2 ETR 0x21 0x01 0x08 0x02 0x10 0x10 0x0D Assuming that the command was accepted by the AV Receiver and is being processed, the AV responds to this command with the following sequence: STR ZONE CC AC DL Data 1 Data 2 ETR 0x21 0x01 0x08 0x00 0x02 0x10 0x10 0x0D

Basic Functions These RC5 codes are present on the supplied IR remote control and provide control over basic amplifier and video processing functions. Advanced Functions These RC5 codes are not present on the supplied remote control but have been created for custom install use. In order for the AVR to respond to these codes they must be transmitted from a programmable IR remote control or over the control link using the ‘Simulate RC5 IR Command’ (0x08).
