18 Russound CA4 System Installation Manual
Serial Port
The CA4 supports RS-232 communication with various third party automation
systems or PC for control, and potential rmware updates of the controller. The
RS-232 port is located on the rear of the CA4 and uses a DB-9 cable connection.
Directions will accompany any rmware updates.
Controller ID Settings

must have its own ID. One of the controllers must be set to 1 (default) and the
other to 2.
Power up the #2 controller (plugging the unit into an electrical outlet). 1.
The installer has 30 seconds to set the ID.
Press and hold the source button on a keypad connected to the #2 2.
controller's wall port for 5 seconds and the source 1 or 2 label will start
blinking, whichever the controller is set to will be displayed. If source 1
blinks then the ID is set to 1. If source 2 blinks then the controller ID is set
to 2. Please note, the default setting is 1.
A press and release of the volume up button will set the controller ID to 3.

be connected.
Please note upon initial power up this parameter should be set within 30
seconds or the controller will revert to normal operation. During power failure
or power cycle this mode will return for the rst 30 seconds of initial power.
Normal operation can still occur during this period.
Note: All four connections from the controller to the wall port must be made,
even if there are less than 4 keypads connected to the system.
Caution: Cables between the wall port and the controller must match
numerically (#1 on Controller to #1 on Wall Port, etc.). Swapping cables to
dierent ports can damage the equipment.
