Serial Control Strings

General Information

Serial Port Communication

Communication Settings: 9600 Baud, 8 data bits, 1 stop bit, No parity

Network Communication

Communication Settings: The default operation of the network card is DHCP mode. This means that the
Network Card will automatically attempt to locate a DHCP server and acquire an IP address from it. If this
fails, it will revert to Static IP mode.
The default static IP settings are:
IP Address: 192.168.1.20
Subnet Mask: 255.255.255.0
Network Commands: All network communication is done over UDP/IP. All telegrams (both client and MRC)
are broadcast over the local network's broadcast address on port 5009, the broadcast address would be
255.255.255.255:5009.
Network commands must be prefixed by "CMRC000000000000".
For communication with multiple controllers on the same network, please call Technical Support.

General Control Information

The Matrix Distributed Audio, multi-room audio control systems can be externally controlled by sending
ASCII text command strings to the Bi-Directional RS-232 serial interface or network interface. Every
command must be terminated with a line feed (0x0A). All messages are case-sensitive.
The MRC will respond to command messages with a status response message once the command has been
executed. In the event that an MRC status changes, the MRC will also send unsolicited status messages (v7.05
and higher).
Unsolicited S ta tus Messages: The MRC will send the following unsolicited status messages when a status has
changed:
MVL
MBS
MTR
MSC
MASON
MASOFF
MASOFF0
MSR
MGL
MBAL
