To setup the LCD, you need the component below:
1. A panel with LVDS interfaces.
2. An inverter for panel’s backlight power.
3. A LCD cable and an inverter cable.
For the cables, please follow the pin assignm ent of the connector to make a cable, because
every panel has its own pin assignment, so we do not provide a standard cable; please find a
local cable manufacture to make cables.
LCD Installation Guide:
1. Preparing the LE-575X/2, LCD panel and the backlight inverter.
2. Please check the datasheet of the panel to see the voltage of the panel, and set the
jumper JVLCD to +12V, +5V or +3.3V.
3. You would need a LVDS type cable.

Chapter 4 <BIOS Setup>
The motherboard uses the Award BIOS for the system configuration. The Award BIOS in
the single board computer is a customized version of the in dustrial standard BIOS for IBM
PC AT-compatible computers. It supports Intel x86 and compatible CPU architecture bas ed
processors and computers. The BIOS provides critical low-level support for the system
central processing, memory and I/O sub-systems.
The BIOS setup program of the single board computer let the customers modify the basic
configuration setting. The settings are stored in a dedicated battery-backed memory,
NVRAM, retains the information when the power is turned off. If the battery runs out of the
power, then the settings of BIOS will come back to the default setting.
