RS-232 Control Commands / Messages

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:

RS-232 Controller Command Messages - These commands can be sent directly to the Delta Audio Controller via the RS-232 (DB9) port on the rear panel. See the Connecting the RS-232 Serial Port section on page 19 for connection and DB9 cabling information.

Delta Audio Controller Status Messages (page 67) - These messages are received via the

RS-232 port, and are used primarily for troubleshooting purposes.

Source Command Codes (page 70) - Source Command Codes, received from the SWT keypads are referenced here by Source Type and Command Index.
