Zone numbers
e following zone numbers are dened:
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
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.
Example command and response sequence
As an example, the command 0x00, change power state – enter standby:
STR ZONE CC DL Data 1 Data 2 ETR
0x21 0x01 0x08 0x02 0x10 0x10 0x0D
Assuming that the command was accepted by the amplier and is being processed,
the MZ8/MZ12 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
AMX Duet™ Support
e MZ8 & MZ12 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”
Response: “AMXB<Device-SDKClass=Amplier><Device-Make=ARCAM><Device-Model=MZ><Device-Revision=x.y>\r”
Where x.y = RS232 protocol version number.
