CVM04 is equipped with components enabling following additional functions.
Backlight Lamps Brightness Control
An adjustable resistor R2 is installed on the module. R2 allows to adjust the brightness of LCD
backlight lamps through changing its resistance according to PS-DA0253-03 DC/AC converter
specification.
R2 resistance is adjusted in a range from 0 to 10 kiloohm. Maximum brightness is achieved at
0 ohm, minimum brightness at 10 kohm. The resistance is increased by turning adjustment screw
clockwise.
LCD Screen Image Orientation Control
It is possible to control LCD screen image orientation using jumpers at XP5 pinboard.
