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.

INTRODUCTION

The All-In-One EPIC board EP850 Series supports Intel
Duo and C-M Penryn processors at FSB 667/800/1067 MHz with
graphics, audio and Gigabit Ethernet interfaces. It practically
integrates chipsets Cantiga GM/GL45 and ICH9M to support excellent
Multiple I/O, LVDS LCD, Gigabit Ethernet and HD digital Audio
interface that make all in one single board as a computing engine. It is
equipped with one 204-pin DDR3 SO-DIMM with maximum 4GB
system memory, LVDS + CRT display devices and one PCI-104 for
32-bit/33 MHz PCI expansion. Additionally, it provides you with unique
embedded features, such as two RS-232 serial ports, six USB2.0
ports for high speed peripherals. It can achieve the best stability and
reliability that makes your system perform the most endurable
operation in any critical environments. The built-in Watchdog Timer
has enhanced the system reliability that achieves a unique feature to
distinguish itself from other boards.
