6.1.11 LCD Backlight (J24)
The brightness control for the LCD backlight has a weak pull-down resistor to ensure maximum brightness when it
is not connected externally. This signal may be controlled by a PWM pin from the processor. A jumper selects the
source of the brightness signal to this pin.

Connector Type: 1x6 1.25mm pitch SMD RA header of Molex# 053261-0671.
Mating cable: Custom cable depending upon the target display. Because of the wide variety of LCDs and the fact
that many applications do not require a display, this cable is not included in the Saturn standard cable kit CK-SAT-
01. DSC cable 6981210 may be used as the starting point for this cable, with the LCD end to be modified by the
customer as per the LCD requirements.
