The yellow Power Control wire in the power cable can either be an input that will turn on the
unit when power is applied, or an output that turns on other devices when the unit is
powered on. It can be configured at the installation stage to control the power state of
displays and compatible devices. When commissioning the system, the unit can be set to be
a Power Control Slave or Power Control Master.
Power Control configuration options of the unit are:
•
Unit turns on when power key pressed: Yellow wire not connected.
•
Unit turns on when power source is turned on: Common red and yellow wires.
•
Unit turns on with power key, as well as other compatible devices such as Broadband
Radar: Yellow wires connected together (Power Control Bus). (Set one or more displays to
be a Power Control Master.)
Power Control unconnected
Device will turn on and off when the power button on the front of the unit is pressed. Leave
the yellow Power Control wire disconnected and tape or heat-shrink the end to prevent
