6.7 Backlight Connector
An external voltage source must be used to supply the backlight with i.e. +12V DC (+5V DC is always avail-
able). The external voltage can be sourced to the backlight connector through the power connector J2901.
This connector can also be used to power the board with +5V DC instead of the round power jacket (see
chapter 'Power Supply').
Note: The backlight voltage that is sourced through connector J2901 can be chosen freely.
6.7.1 External Voltage
Parameter Min. Typ. Max. Units
Input voltage +12.0 +30.0 V
Continuous input current 1.0 A
6.7.2 Backlight Voltage Jumper
Check the jumper J1201 for the correct backlight voltage ( Pos. 1-2 = +5V 2-3 = external voltage ).
