RS-232 Control Commands / Messages
Delta Audio Controllers provide an RS-232 (DB9) port for receiving RS-232 Controller Commands.
Refer to the
RS-232 Controller Command Messages
section on page 55 for a complete listing of
supported commands.
Connector: DB9 Male
Communications: 4800 Baud, 8 data bits, 1 stop bit, no parity
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. 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.
This section provides reference information for the following:
