Channels - 8 bit 256 Step Levels

You can work with 8 bit 256 step levels.
Action
Increase 1 bit
Decrease 1 bit
Show 256 bit levels
EXPLANATION
Levels for channels controlling dimmers are traditionally set from 0-100%. The internal resolution of
DMX 512 however, is about 2.5 times greater, from 0 to 255. You may want to use this higher
accuracy when you are setting values for mechanical dimming devices.
The board will display the %-value rounded off to the closest value. (1.4% will be displayed as 1%
and 1.6% will be displayed as 2%)
To convert between 0-100% and 0-255 raw DMX levels, you divide the % level with 0.39
(100/255=0.39). For example: 50% / 0.39 = 128 bit steps (actually 128.21)
The other way around you multiply by the same factor of 0.39. Example: 129 x 0.39 = 50,31%
NOTE
256 bit step levels are not displayed on the channel screen, but are stored with
the show and exported in ASCII Light Cues.
