Analogue Compass Repeaters 056376/A
Dimming Values 6-13
Serial Dimming Command Evaluation
When serial dimming is used, the analogue repeater reads the com-
manded brightness percentage from the $--DDC or $PPLAI sentence,
respectively. At a dim offset of 0, the range of possible percentage val-
ues, is mapped to the repeater’s eight brightness levels as follows:
Table 6-1:

level mapping
If the dim offset is set to a value other than 0, via the setup or by adjust-
ing the brightness with the
DIM keys, the effective brightness of the
repeater is altered by the corresponding number of steps up or down.

Note
The analogue repeater evaluates the brightness percentage field from
the $--DDC or $PPLAI sentences only. The dimming preset and colour
palette fields are ignored.
