Amx Duet™ Support - Arcam SA20 Custom Installation Notes

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 (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 SA10/SA20 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
0x21 0x01
Assuming that the command was accepted by the SA10/SA20 and is being processed, the SA10/SA20 responds to this command with the following sequence:
St Zn
0x21 0x01
AMX Duet™ support
The SA10/SA20 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"
Response: "AMXB<Device-SDKClass=Amplifier><Device-Make=ARCAM><Device-Model=SA10><Device-Revision=x.y.z>\r"
Response: "AMXB<Device-SDKClass=Amplifier><Device-Make=ARCAM><Device-Model=SA20><Device-Revision=x.y.z>\r"
Where,
x.y.z = RS232 protocol version number.
