Wiring and Connections

Connecting the RS-232 Serial Port

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.

RS-232 Cable

When connecting to the RS-232 port located on the back of the Delta Controller, it is necessary to use a DB9 cable. Delta Controllers utilize DCE protocol therefore no NULL modem adapter is necessary. You may also use a USB to DB9 adapter.

Tools Required for Installation

Tools you’ll need to complete this part of the installation are wire strippers, small standard slotted screwdriver and a permanent marker. An optional tool is an ohmmeter to determine which side of the wire you are working with if they were not marked. If the wires are not secured to an electrical box use masking tape to help secure the cable while you are working on it. There is nothing more frustrating than having the cable fall back behind the wall. It’s also recommended to have a Speaker Impedance Meter (not just a DMM) so that you can accurately read speaker impedance.

Orientation of Connectors

Looking at the rear of the keypad with the connectors at the bottom, you will see (2) plug type 4 pin receptacles. Generally the mating connector parts shipped in a separate hardware bag that is packaged with the Delta Controller.

The connector on the right side terminates the 4 conductor wire from the Delta Controller and the connector on the left side passes the audio to the speakers in the zone. The Matrix keypad is distinctively marked on the back, and the connector on the right side is labeled vertically indicating the line from the Delta Controller and the connector on the left side is labeled vertically indicating the line leading to the speakers, so this should make installation less of a guessing game.

Be sure to match the color and position of the wiring at the keypad with the wiring at the Controller (FIG. 13).
