Note: The LVDS Detect Pin please contact to the Panel GND.
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 assignment of the connector to make a cable, because

17
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-37D, 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 or +5V or +3.3V.
3. You would need a LVDS type cable.
4. To connect all of the devices well.
After setup the devices well, you need to select the LCD panel type in the BIOS.

The USB3.0 port need to Install USB 3.0 eXtensible Host Controller Driver and
enable xHCI Mode.
2.10.1 USB 3.0 eXtensible Host Controller Driver install
Step1. Copy the USB 3.0 driver from “Driver CD” to the local hard driver directory.
(Do not run this driver from a USB storage device)
Interface USB3.0

Step2. Configure default BIOS, click Advanced > South Cluster Configuration > USB
Configuration, disable “EHCI Mode”.
Step3. enable “xHCI Mode” and push “F10” to save configuration. Restart your
computer.
Step4. If you enable xHCI Mode , USB 2.0 and USB 3.0 ports can’t use without
drive. We recommend that you connect PS/2 mouse / keyboard installing
USB 3.0 driver.
