Chapter 1. Introduction
The WAFER-5823 is a CPU board equipped with two ethernet
controllers so it is a special design most appropriate for
Network applications. It supports the full functions of an
AT-compatible industrial computer on a single board. The
WAFER-5823 is also equipped with a low-power consumption
and high performance GX1 processor on board moreover
contains an SDRAM SODIMM socket that can support up to
512MB memory.
The WAFER-5823 aside from providing two Ethernet interfaces,
it also has FDD interface, EIDE interface, Compact Flash Type II,
one parallel port, two serial ports RS232, two USB ports, and a
6-pin header PS/2 keyboard/mouse interface. The built-in
SVGA/LCD display controller supports both CRT and LCD display
simultaneously. It offers the resolutions of LCD screen up to
1024 x 768 and CRT resolutions up to 1280 x 1024 @ 256
colors. The Flash ROM contains both the system BIOS and the
VGA BIOS. If necessary, reprogramming the Flash ROM could
do the modification to fit actual need.

Chapter 2. Installation
This chapter gives instructions on how to setup and configure
WAFER-5823 board, including directions on how to set jumpers
as well as connecting peripherals, switches and indicators.
Before installation, please pay attention to the unpacking
precautions on the following page to ensure safety.

2.2 Unpacking Precautions
Some components of WAFER-5823 SBC are very sensitive to
static electric charges and can be damaged by a sudden rush of
power. To protect it from unintended damage, please be sure to
pay attention to these following precautions:
1. Ground yourself to remove any static charge before
touching the WAFER-5823 SBC. You can do it by using a
grounded wrist strap at all times or by frequently touching
any conducting materials that is connected to the ground.
2. Handle your WAFER-5823 SBC by its edges. Don’t touch IC
chips, leads or circuitry if not necessary.
3. Do not plug any connector or jumper while the power is
on.
2.3 System Memory DRAM
There is one 144-pin SO-DIMM socket that supports 3.3V
non-buffered SDRAM. Maximum memory size is 512MB.
2.4 Watch-Dog Timer Setting
Reading port 443H enables the Watchdog Timer. It should be
triggered before the time-out period ends, otherwise it will
assume the program operation is abnormal and will issue a
reset signal to start again. Reading port 043/843H disables the
Watchdog Timer. Refer to Appendix A for detailed information

2.5 Clear CMOS Setup
If you need to clear the CMOS Setup (For example, you have
forgotten the password. Then what you should do is to clear
setup and reset the password.), you should close the JP1 for
about 3 seconds then open it again. Opening JP1 can set
system back to normal operation mode.
