Example
Read the backlight level of the monitor at address 0.7 (group 0, address 7), which is
used in ECDIS mode:
According to the data returned by the monitor at address 0.7 (group 0, address 7),
the backlight level in ECDIS mode is 255 (0xFF):
Note:
The backlight level for ECDIS mode depends on the backlight level value sent with the
“BRT” command. Whenever the monitor receives a new backlight level value, it is au-
tomatically assumed to be used in the ECDIS mode, too. This means, if for example the
backlight level value 200 is sent, then the backlight level is manually changed to 150,
activating the ECDIS mode will reset the backlight level to 200 again.
