Logic Geode LX User manual

Geode LX LCD Adaptor Board
QuickStart Guide
Before using the LCD adaptor board, the BIOS settings for the Geode LX
must be set to drive the LCD signals. Because procedures for altering
BIOS settings differ between vendors, please check with your BIOS
vendor for specific instructions on how to make this change.
1. Align the boards such that the TFT headers and touch/backlight
header pins face one another (see Figure 1).
Figure 1 — Align boards
2. The silk screens of both boards are labeled to designate which 6-pin
header is for touch and which is for backlight. Connect one of the 6-
pin ribbon cables to the header pins labeled “TOUCH” (designator
J37) on the LX mini-ITX baseboard and connect the other end of the
cable to the row of pins labeled “TOUCH” (J3) on the LCD adaptor
board (see Figure 2).

3. In the same manner, connect the other 6-pin ribbon cable to the
backlight header pins (J31) on the LX mini-ITX baseboard and to the
appropriate header pins (J2) on the LCD adaptor board. When
connected properly, the two cables should lay one on top of the other
and not cross at any point (see Figure 3).

4. The ribbon cable to connect the TFT headers is keyed such that it
can only be inserted in one direction (see Figure 4.1). Connect the
cable to the header labeled “TFT HEADER” (J23) on the LX mini-ITX
baseboard by pressing straight down on the connector (see Figure
4.2). In the same manner, connect the other end of the cable to the
TFT header (J4) on the LCD adaptor board.
