Introduction

WAFER-5820 is designed for limited space applications with
only the size of a 3½" hard drive. It supports the full functions of an
AT-compatible industrial computer on a single board. The
WAFER-5820 is equipped with a low-power consumption and high
performance GXLV-233 processor on board. It also contains an
SDRAM SODIMM socket that can support up to 128MB memory.

The WAFER-5820 provides an Ethernet interface, audio
interface, socket for DiskOnChip, EIDE interface , one parallel port,
one serial ports RS-232 , one series ports RS-232/422/485 with
self-tuner , and a mini-DIN PS/2 keyboard/mouse interface. The
built-in SVGA/LCD display controller supports both the CRT and
LCD display simultaneously. It offers the resolutions of LCD
screen up to 800 x 600 and CRT resolutions up to 1280 x 1024 @
16 colors. It also provides LVDS interface for long distance LCD
panel signal transmission. The display type is configured by
software utility. The Flash ROM contains both the system BIOS
and the VGA BIOS. The modification, in case of necessary, could
be done by reprogramming the Flash ROM.

The RS485 has an outstanding characteristic of intelligent
directing control which eliminates the extra control signal like RTS.
With this feature you can develop your program as you are using a
normal RS232 without special control routine. This is especially
important in WINDOWS programming which do not allow the
program to catch the control pin at your wish.

Finally, one PC/104 connector is included for the future
application you will need.

2.2 Unpacking Precautions

Some components of WAFER-5820 SBC are very sensitive to
static electric charges and can be damaged by a sudden rush
of power. To protect it from unintended damage, be sure to
note these precautions:

Ground yourself to remove any static charge before touching
the Wafer-5820 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.
Handle your Wafer-5820 SBC by its edges. Don’t touch IC
chips, leads or circuitry if not necessary.
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 to accept 3.3V
non-buffered SDRAM. The max. Memory size is 128MB.

2.4 Watch-Dog Timer Setting

The Watch-Dog Timer is enabled by reading port 443H. 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, or activate NMI to CPU. The
Watch-Dog Timer is disabled by reading port 043/843H.detail

2.5 Clear CMOS Setup

If you need to clear the CMOS Setup (for example forgot the
password you should clear the setup and then set the
password again.), you should close the JP9 about 3 seconds,
then open it again. Set back to normal operation mode, open
JP9.

The COM2 (CN9) can supply +5V or +12V power to the serial
devices via RI pin (Pin 8) of the COM port connector. The max.
current is 1A with fuse protection, from these two connector’s
5V/12V output. If the output is set to 12V, make sure that you
have 12V to supply to the board.

The COM2 (CN9) can be set to RS-232 or RS-422/485 for
industrial field site application. Moreover when this port set to
the RS-485 mode the board equipped self-tuner IC will
automatic sensing the data direction to eliminate the data
collision. This is especially important in WINDOWS
programming which do not allow the program to catch the
control pin at your wish.

2.8 DiskOnChip™ Flash Disk Memory Address setting

The DiskOnChip™ Flash Disk Chip (DOC) is produced by
M-Systems. Because the DOC is 100% compatible to hard disk
and DOS Customer don‘t need any extra software utility. It is
just “plug an d play”, easy and reliable. Right now the DOC is
available from 2MB to 144MB.The MD-2200-Xmb series DOC

will share only 8KB memory address.
