BCM: Brightness Lock
3 basic modes: Uncalibrated
– Brightness locking not active so dimmer wheel stays in last known position.
– Color correction not active so native colors are shown.
Brightness locked– The brightness is dynamically controlled with the dimmer
wheel by using only the brightness information of the color sensor. The colors are static.
Sense 6 (License required, see BLM)– Next to Brightness, color is also dynamically controlled. This
is done with the DMD chip.
