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 electronics
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（SODIMM）Installation
The A831 SBC provides one 200-pin SODIMM slot. The socket supports up to 1GB
DDR 400 SDRAM. When installing the Memory device, please follow the steps
below：
Step.1. Firmly insert the SODIMM at an angle into its slot. Align the SODIMM on the
slot such that the notch on the SODIMM matches the break on the slot.
Step.2. Press downwards on SODIMM until the retaining clips at both ends fully snap
back in place and the SODIMM is properly seated.
¾
Caution!
The SODIMM only fits in one correct orientation. It will cause
permanent damage to the development board and the SODIMM if
the SODIMM is forced into the slot at the incorrect orientation.

2.2 I/O Equipment Installation
2.2.1 PS/2 Keyboard and PS/2 Mouse
The A831 SBC provides a Mini-DIN connector supports PS/2 interface. Mini-DIN
connector supports Keyboard and Mouse through Y cable. Please plug keyboard or
mouse directly with Y cable. 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.
2.2.2 Audio function
The AC’97 capabilities are provided by a Realtek ALC203 chip supporting digital
audio outputs. The onboard ALC203 is a 20-bit DAC and 18-bit ADC supporting
full-duplex AC’97 2.3 compatible stereo audio CODEC for multimedia, including
host/soft audio based designs. The audio interface includes two jacks: microphone-in
and line-out.
2.2.3 Serial COM ports
One RS-232 ports with 16C550 UART (or compatible) with 16-byte FIFO buffer.
Three 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 Ethernet interface
The Motherboard is equipped with dual Realtek RTL8100C or optional dual Realtek
RTL8110SC Gigabit Ethernet chipset which is fully compliant with the PCI 10/100
Mbps Ethernet protocol compatible. It is supported by major network operating
systems. The Ethernet port provides a standard RJ-45 jack.
2.2.5 USB ports
Four USB (Two is optional) device 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.
2.2.6 External 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. VGA connector is a standard 15-pin D-SUB connector.

2.4 Jumper Setting 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 configuration 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.
