Key Purpose Color
A Power control wire Yellow
B Ignition switch
Power controlled by master slave bus
The yellow power control wire 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.
Key Purpose Color
A Power control wire Yellow
B Master slave bus
If a unit is configured as power control master and turned on by the power key, it will output
voltage on the power control bus. This will power on both other power master units and
power slave units. If a unit is set to power control slave, it cannot be powered down using its
own power key while a power control master unit is turned on. Pressing the power key will
set the unit to standby. If all power control masters are off, power control slaves can be
turned on using their own power key. This however will not turn on any other units
connected to the power bus.
