Delta Series Audio Controllers
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.
Connecting Matrix Keypads
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).
