Backlight Inverter Interface
The supply voltage of the backlight can be adjusted with jumper JP1102. The according
position is printed on the PCB.
DIP switch S2804 #3 should be set according to the backlight inverter used.
If the inverter needs a low active start signal, DIP-Switch S2804 #3 has to be set open.
If the inverter needs a high active start signal, DIP-Switch S2804 #3 has to be set on.
Brightness of the backlight inverter is controlled via the LVDS-BKLT-CTRL signal.
The LVDS-BKLT-CTRL signal of the COM Express module is routed straight to the
backlight inverter connector.
