ESD Precautions

Computer boards have integrated circuits sensitive to static electricity.
To prevent chipsets from electrostatic discharge damage, please take
care of the following jobs with precautions:

 Do not remove boards or integrated circuits from their anti-static

packaging until you are ready to install them.

 Before holding the board or integrated circuit, touch an unpainted

portion of the system unit chassis for a few seconds. It
discharges static electricity from your body.

 Wear a wrist-grounding strap, available from most electronic

component stores, when handling boards and components.

through high-bandwidth interfaces, multiple I/O functions for interactive
applications and various embedded computing solutions. The board
has one 200-pin unbuffered SODIMM sockets for DDR2 400/533 MHz
SO-DIMM memory, maximum memory capacity up to 2GB. It also
features Gigabit/Fast Ethernet, one serial ATA port, four USB 2.0 high
speed compliant, built-in high definition audio codec that can achieve
the best stability and reliability for industrial applications. It provides
you with unique embedded features, such as two serial ports (2x RS-

232) and Pico-ITX form factor that applies an extensive array of PC
peripherals. The board can be enhanced by its built-in watchdog timer,
a special industrial feature not commonly seen on other motherboards.

 Power LED

This 3-pin connector denoted as Pin 1 and Pin 5 connects the
system power LED indicator to such a switch on the case. Pin 1 is
assigned as +, and Pin 5 as -. The Power LED lights up when the
system is powered ON.

 External Speaker and Internal Buzzer Connector

Pin 2, 4, 6 and 8 can be connected to the case-mounted speaker
unit or internal buzzer. While connecting the CPU card to an internal
buzzer, please short pins 2-4; while connecting to an external
speaker, you need to set pins 2-4 to Open and connect the speaker
cable to pin 8 (+) and pin 2 (-).

 ATX Power On/Off Button

This 2-pin connector denoted as Pin 9 and 10 connects the front
panel’s ATX power button to the CPU card, which allows users to
control ATX power supply to be power on/off.

 System Reset Switch

Pin 11 and 12 can be connected to the case-mounted reset switch
that reboots your computer instead of turning OFF the power switch.
It is a better way to reboot your system for a longer life of the
system’s power supply.

2.4.8 Digital I/O Connector (CN8)

The board is equipped an 8-channel digital I/O connector CN8 that
meets requirements for a system customary automation control. The
digital I/O can be configured to control cash drawers, sense warning
signals from an Uninterrupted Power System (UPS), or perform store
security control. The digital I/O is controlled via software programming.
