Backlight Level Down Range
By default, the backlight level of a Lauer Navigation Monitor can be changed within
the full range of 0 to 255 steps by using the front panel keys. To allow the backlight
level change within a limited range, a delta value can be defined. The delta value sets
the upper and lower backlight level range limits relative to the ECDIS backlight value
(which is set by the SCOM command “BRT”). Normally, upper and lower range
limits are defined as 255 for full range support. The value returned by this command
is the lower range limit relative to the ECDIS backlight level.
Supported since Firmware Version
