JB1 Backlight brightness voltage range 1-2 closed = 5V max
2-3 closed = 3.3V max
JB2 Backlight inverter on/off control – signal level 2-3 = On/Off control signal ‘High’ = +5V
1-2 = On/Off control signal ‘High’ = +3.3V
Open = On/Off control signal ‘High’ = Open collector
CAUTION: Incorrect setting can damage inverter.
JB3 Backlight inverter on/off control – polarity 1-2 = control signal ‘high’ = CCFT ON
2-3 = control signal ‘low’ = CCFT ON
JB4 GPIO pins voltage selection 1-2 = 3.3V
2-3 = 5V
JB5 Backlight control type selection 1-2 = VR/Digital switch mount control
3-4 = Analog backlight brightness - voltage range 0~5V
5-6 = PWM (Pulse Width Modulation) brightness
JC1 Custom configuration Position 2 :
Closed = Enable save Current Settings as Calibrated
Values on OSD menu
Position 3 :
Closed = Enable baud rate selection function in
programming mode
Position 4 :
