Backlight Level Up Range
By default, the backlight level of a Beijer Electronics Nautic 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 upper range limit relative to the ECDIS backlight level.
Supported since Firmware Version
MT230 Nautic Monitor: 1.0
