Safety Precautions
Warning!
Always completely disconnect the power cord from your chassis
whenever you work with the hardware. Do not make connections
while the power is on. Sensitive electronic components can be
damaged by sudden power surges. Only experienced electronic
personnel should open the PC chassis.
Caution!
Always ground yourself to remove any static charge before
touching the CPU card. Modern electronic devices are very
sensitive to static electric charges. As a safety precaution, use a
grounding wrist strap at all times. Place all electronic components
in a static-dissipative surface or static -shielded bag when they are
not in the chassis.

Chapter 2 Installations
2.1 Memory Module（DIMM）Installation
IA70 motherboard supports one DDR2 memory socket for a maximum total memory
of 2GB in DDR2 memory type.
2.1.1 Installing and Removing Memory Modules
To install the DDR2 modules, locate the memory slot on the board and perf orm the
following steps:
1. Hold the DDR2 module so that the key of the DDR 2 module align with those on
the memory slot.
2. Gently push the DDR 2 module in an upright position until the clips of the slot
close to hold the DDR 2 module in place when the DDR 2 module touches the
bottom of the slot.
3. To remove the DDR2 module, press the clips with both hands.

2.2 I/O Equipment Installation
2.2.1 12V DC-IN
The Motherboard allows plugging 12V DC-IN jack on the board without another
power module converter under powered consumption by Intel Atom N270 1.6GHz
processor.
2.2.2 PS/2 Keyboard and PS/2 Mouse
The Motherboard provides two PS/2 interface. The PS/2 connector supports Keyboard
and Mouse. In other cases, especially in embedded applications, a mouse is not used.
Therefore, the BIOS standard setup menu allows you to select* “All, But Keyboard”
under the “Halt On”. This allows no -keyboard operation in embedded system
applications without the system halting under POST.
2.2.3 Serial COM ports
Three RS-232 connectors build in the rear I/O . Fourth optional COM ports support
RS-232. When an optional touch -screen is ordered with PPC, serial com port can
connect to a serial or an optional touch -screen. One optional COM port supports
RS232/422/485 choice through jumper setting.
2.2.4 Internal VGA
The Motherboard has one VGA port that can be connected to an external CRT/ LCD
monitor. Use VGA cable to connect to an external CRT / LCD monitor, and connect
the power cable to the outlet . The VGA connector is a standard 15 -pin D-SUB
connector.
2.2.5 Ethernet interface
The Motherboard is equipped with Dual Realtek RTL8111B chipsets which is fully
compliant with the PCI 10/100 /1000 Mbps Ethernet protocol compatible. It is
supported by major network operating systems. The Ethernet port s provide two
standard RJ-45 jacks.
2.2.6 USB ports
Eight USB devices (four with pin headers) may be connected to the system though an
adapter cable. Various adapters may come with USB ports. USB usually connect the
external system to the system. The USB ports support hot plug -in connection.
Whatever, you should install the device driver before you use the device.

2.2.7 Audio Jack ( Pin-header)
The Audio 5.1 channel capabilities are provided by a Realtek ALC655 chipset
supporting digital audio outputs. The audio interface includes Mic-in,: line-in and
line-out.

2.4 Jumper Setting
A pair of needle-nose pliers may be helpful when working with jumpers. If you have
any doubts about the best hardware config uration for your application, contact your
local distributor or sales representative before you make any changes. Generally, you
simply need a standard cable to make most connections.
The jumper setting diagram is as below. If a jumper shorts pin 1 and pi n 2, the setting
diagram is shown as the right one.
The following tables list the function of each of the board's jumpers.
