Introduction
This document describes the remote control protocol for controlling via the RS232/NET interface.
Set-up
IP control is via port 50000 of the IP address of the unit.
Conventions
All hexadecimal numbers begin 0x.
Any character in single quotes gives the ASCII equivalent of a hex value.
<n> represents an unknown or variable number.

The cable is wired as a null modem:

Data transfer format
Transfer rate: 38,400bps
Data format: 8 data bits, 1 stop bit, no parity, no ow control.
Command and response formats
Communication between the remote controller (RC) and the SA30 takes the form of sequences of bytes, with all commands and responses having the same
basic format. The SA30 shall always respond to a received command, but may also send messages at other times.
Each transmission by the RC hs the following format:
<St> <Zn> <Cc> <Dl> <Data> <Et>
• 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 Et
• Data: the parameters for the command
• Et (End transmission): 0x0D
Each response by the SA30 has the following format:
<St> <Zn> <Cc> <Ac> <Dl> <Data> <Et>
• St (Start transmission): 0x21 ‘!’
• Zn (Zone number): see “Zone numbers”, below
• Cc (Command code): the code for the command
• Ac (Answer code): see “Answer codes”, below
• Dl (Data Length): the number of data items following this item, excluding the Et
• Data: the parameters for the response of length n (note that n is limited to 255)
• Et (End transmission): 0x0D
The SA30 responds to each command from the RC within three seconds. The RC may send further commands before a previous command response has been
received.
Zone numbers
The following zone numbers are dened:
• 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 dened:
• 0x00 – Status update.
• 0x82 – Zone Invalid.
• 0x83 – Command not recognised.
• 0x84 – Parameter not recognised.
• 0x85 – Command invalid at this time (see NOTE below)
• 0x86 – Invalid data length.
NOTE: Certain 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 SA30 may be changed as a result of user input via front panel or remote. Any change resulting from these inputs is relayed to
the RC using the appropriate message type.
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” (increase volume):
St Zn Cc Dl Data 1 Data 2 Et
0x21 0x01 0x08 0x02 0x10 0x10 0x0D
Assuming that the command was accepted by the SA30 and is being processed, the SA30 responds to this command with the following sequence:
St Zn Cc Ac Dl Data 1 Data 2 Et
0x21 0x01 0x08 0x00 0x02 0x10 0x10 0x0D
AMX Duet™ support
The SA30 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 nd 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 benet
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 specied in the ASCII format. All ASCII characters between the quotes “” should be recognised/transmitted. “\r” is a carriage return (0x0D).
Command: “AMX\r”
Response: “AMXB<Device-SDKClass=Amplier><Device-Make=ARCAM><Device-Model=SA30><Device-Revision=x.y.z>\r”
Where,
x.y.z = RS232 protocol version number.
