AMX Duet™ Support

eAVR500/AVR600/AV888 shall be fully compatible with AMX Duet™ Dynamic Device Discovery Protocol (DDDP) e 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 benet for end users. e 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 specied in the ASCII format. All ASCII characters between the quotes “” should be recognised/transmitted. “\r” is a carriage return (0x0D)

Command: “AMX\r”

AVR600 Response:

“AMXB<Device-SDKClass=Receiver><Device-Make=ARCAM><Device-Model=AVR600><Device-Revision=x.y.z>\r”

AV888 Response:

“AMXB<Device-SDKClass= PreAmpSurroundSoundProcessor ><Device-Make=ARCAM><Device-Model=AV888><Device-Revision=x.y.z>\r”

Where

x.y.z = RS232 protocol version number.

command response has been received.

Zone numbers

e following zone numbers are dened:

 0x01 – Zone number 1. (Zone 1 is the master zone. Commands that appear zone-less refer to the master zone)

 0x02 – Zone number 2.

 0x03 – Zone number 3.

Answer codes

e following answer codes are dened:

 0x00 – Status update.

 0x82 – Zone Invalid.

 0x83 – Command not recognised.

 0x84 – Parameter not recognised.

 0x85 – Command invalid at this time.

 0x86 – Invalid data length.

State changes as a result of other inputs

It is possible that the state of theAVR500/AVR600/AV888 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 (dened 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, theAVR500/AVR600/AV888 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

1 2 3 4 5 6 7 8 9 ... 29 30
