Mi Series Audio Controllers
RS-232 Cable
When connecting to the RS-232 port located on the back of the Mi Series Controller, it is necessary to
use a DB9 cable. The Mi Series Controller utilizes DCE protocol therefore no NULL modem adapter is
necessary. You may also use a USB to DB9 adapter.
Matrix MRC RS-232 Command Definition
Connector: DB9 Male
Communications: 9600 Baud, 8 data bits, 1 stop bit, no parity
General
All messages are sent using ASCII text strings. Every command and status message is terminated with a
line feed (0x0A or 10). All messages are case sensitive.
The MRC will respond to the command messages sent by the Host and will not send any messages
except in this case. If the Host sends a new message before the MRC has responded to the previous
message, the MRC will ignore the new message.
The Host should always start its communication with the MRC by sending a “Get Configuration”
command to determine the capabilities of the unit it is controlling.
Not all MRC products support all of the functionality which is specified in the Command Definition.
Commands must be in UPPERCASE • Valid Commands do not require CR/LF
Valid Commands are confirmed with “Command Issued”
Invalid commands are responded to with “ERROR”
A complete listing of the RS-232 commands for the Mi Series Controller is available
for download via the InConcert section of the www.amx.com website (search
"Manufacturers" for "AMX Matrix").
