Chapter 1 Introduction
WAFER-C400EV is designed for network applications. It supports the full functions
of an AT/ATX-compatible industrial computer on a single board. The
WAFER-C400EV is equipped with a low-power consumption and high performance
Intel Mobile processor on board. It also contains an SDRAM SODIMM socket that
support up to 512MB memory.
The WAFER-C400EV provides two Ethernet interfaces, one FDD interface, one
EIDE interface, one audio interface, one Compact Flash Type II, one parallel port,
one RS-232 serial port, one RS-232 / RS-422 / RS-485 header, one 2x25-pin LCD
header, one PC-104, two USB 2.0 ports, one 5-pin IR header, and one 6-pin
header of 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 1024 x 768 @ 60HZ, and CRT resolutions up to
1600 x 1280 @ 64K colors. The Flash ROM contains both the system BIOS and
the VGA BIOS. Reprogramming the Flash ROM could do the modification, in case
of necessary.

This chapter gives instructions about how to set up the WAFER-C400EV hardware,
including directions of setting jumpers and connecting peripherals, switches and
indicators. Before installation, please pay attention to the unpacking precautions
on the following page for safety.

2.2 Unpacking Precautions
Some components of WAFER-C400EV 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:
1. Ground yourself to remove any static charge before touching the
WAFER-C400EV 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 WAFER-C400EV 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 to accept 3.3V non-buffered SDRAM. The
max 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. Please refer to Appendix A for detailed information.
2.5 Clear CMOS Setup
If the user needs to clear the CMOS setup (for example, the user forgot the
password, then the setup should be cleared and the password should be re-set).
The user should short the JP1 about 3 seconds, and then open it again. Opening
JP1 can set the system back to normal operation mode.
