5.4.2 Parameter window “X: dimming”
Fig. 5.5 Parameter window “X: dimming”
This window is used to set the parameters in the brightness dimming mode. There are 2 type of brightness
dimming mode: Relative dimming and Brightness value:
Relative Dimming
Parameter “low dimming threshold 1...127
（
0.4%...49.9%)”
This parameter defines the low threshold value of the relative dimming. When it is smaller than the low
threshold, it is not allowed to dim DOWN, only to dim UP, the range is 1~127 (0.4%
～
49.9%). Supposing the low
threshold is 50, if the current brightness value is smaller than 50, so it is not allowable to dim DOWN until
dimming UP to above 50.
Parameter “upper dimming threshold 128...255
（
50.2%...100%)”
This parameter defines the high threshold value of the relative dimming. When it is greater than the high
threshold, it is not allowed to dim UP, only to dim DOWN, the range is 128~255 (50.2%
～
100%). Supposing the
high threshold is 200, if the current brightness value is greater than 200, it is not allowable to dim UP until dim
DOWN to below than 200.
Parameter “If dimming down and value <=low dimming threshold output switch”
This parameter defines the action after relative dimming, whether it will be off or stay in the low threshold
value. Options:
Off
To low threshold value
