Zone numbers

The following zone numbers are defined:

0x01 - Zone number 1. (Zone 1 is the master zone. Commands that are global are addressed to Zone 1)

0x02 - Zone number 2.

0x03 - Zone number 3.

0x04 – Zone number 4.

0x05 – Zone number 5.

0x06 – Zone number 6.

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.

0x86 – Invalid data length.

Example command and response sequence

As an example, the command 0x00, change power state – enter standby:

STR

ZONE

0x21

0x01

Assuming that the command was accepted by the amplifier and is being processed,

the MZ8/MZ12 responds to this command with the following sequence:

STR

ZONE

0x21

0x01

AMX Duet™ Support

The MZ8 & MZ12 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=MZ><Device-Revision=x.y>\r"

Where x.y = RS232 protocol version number.
