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
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 LS-37A, 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.

2.12 <PCIE Mini Card and SIM Interface>
The board provides two PCIE mini card slots and a SIM socket.
MINI_CARD1 is the first Mini-PCIe slot for long size Mini-PCIe cards.
Please be noted that the MPX-SDVOD card must be placed in this slot. The
MPX-SDVOD card will not work if it is placed in other slot.
Please also be noted that this slot is the only slot for MPX-SDVOX card but a
customized BIOS is needed for the MPX-SDVOX card. Please contact Commell for
customized BIOS for your MPX-SDVOX card.
MINI_CARD2 is the second Mini-PCIe slot for long size Mini-PCIe cards.
However, if you are trying to use 3G Mini-PCIe card with a SIM card then place your 3G
Mini-PCIe card in this slot and put your SIM card into the SIM card socket beneath this
MINI_CARD2 slot, and option support mSATA

Chapter 4 <BIOS Setup>
The motherboard uses the Phoenix BIOS for the system configuration. The Phoenix
BIOS in the single board computer is a customized version of the industrial standard
BIOS for IBM PC AT-compatible computers. It supports Intel x86 and compatible CPU
architecture based 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.
The BIOS section of the manual is subject to change without notice and is provided here
for reference purpose only. The settings and configurations of the BIOS are current at
the time of print, and therefore they may not be exactly the same as that displayed on
your screen.
To activate CMOS Setup program, press ＜DEL＞ key immediately after you turn on the
system. The following message “Press DEL to enter SETUP” should appear in the lower
left hand corner of your screen. When you enter the CMOS Setup Utility, the Main Menu
will be displayed as Figure 4-1. You can use arrow keys to select your function, press
＜Enter＞ key to accept the selection and enter the sub-menu.
