1 Introduction of WCP-640
The WCP-640 is a high-performance single-board computer (SBC)
supported by powerful Socket 370 processors. With a PCI flat panel
controller, a PCI 100Base-Tx Ethernet interface, and a 100MHz frontside
bus, WCP-640 surpasses any other SBC in its class. In addition, the
onboard SSD interface supports M-systems DiskOnChip 2000 series up to
288MB. This compact board(only 7.1”x5”) offers all the functions of a
single-board industrial computer.
Its on-board I/O features include two serial ports, one multi-mode
parallel (ECP/EPP/SPP) port, an IrDA- compatible infrared port, two
USB (Universal Serial Bus) ports, standard floppy drive connectors, and
a keyboard and PS/2 mouse connector. The built-in high-speed EIDE
controller supports Ultra DMA 33/66 mode. Up to two IDE devices can
be connected, including large hard disks, CD-ROM drives, tape backup
drives, and more. To enhance its expansiveness, one 16-bit ISA PC/104
connector is also mounted on board.
In addition, the board features a synchronous switching regulator and
advanced power and system management functions. It complies with the
APM V1.2 and ACPI V1.0 standards and supports three types of power
saving features: Doze mode, Standby mode, and Suspend mode. One Dual
Inline Memory Module (DIMM) slot supports 3.3V SDRAM memory up
to 128MB. The onboard watchdog timer can automatically reset the
system or generate an interrupt when the system hangs due to the
program malfunction.
Certainly, WCP-640 is an easy-to-expand yet highly integrated
multimedia SBC that combines video, and network functions on a
CD-ROM drive size form factor, with up to 1024 x 768 resolution (64K
colors, 1024 x 768 with 16M colors for the C&T 69030 VGA chip) and
built-in 2MB SDRAM display memory.

2 Components Setup
This chapter describes how to set up the WCP-640 board, including
instructions on setting jumpers and connecting peripherals, switches, and
indicators. Be sure to read all the safety precautions before you begin the
installation procedure.
2.1 About Jumpers, Switches, and Connectors
The board has a number of jumpers and switches that allow you to
configure your system to suit your applications. In addition, the
connectors on the board link it to external devices such as hard disk
drives, COM ports, and floppy drives.
Jumpers are used on this board to select various settings and features. A
jumper consists of several metal pins and a small metal cap (often
protected by a plastic cover) that slides over the pins to connect them. To
close a jumper you connect the pins with the cap. To open a jumper you
remove the cap. 2-pin jumper has two settings: open and closed
(shorted). 3-pin jumper can have pins 1-2 or 2-3 connected. A jumper
block can be set to odd-to-even pin connections (example: pins 1-2
shorted or pins 5-6 shorted). The jumper pin number is labeled on the
printed circuit board.
In addition to jumper settings, some of this board’s functions are adjusted
through the DIP switches. The types of jumper and switch diagrams used
in this manual are shown below. The black block in the graphic represents
the switch’s position.

2.4 Installing CPU
WCP-640 supports Intel Celeron and Pentium III CPUs, with built-in autodetectVcore voltage
function on Chip VT82C596B. Therefore, what users have to do is to identify their specific
processor for the socket 370 on board and insert it correctly. As soon as power is on,
WCP-640 will autodetect the proper voltage for the CPU and start to run it in your system.
Users will no longer bother to adjust the CPU voltage themselves. Yet they should also remind
themselves that overclockingthe CPU isnot allowed on WCP-640 either.
2.4.1 Identifying the CPU
All CPUs for Socket 370 are mounted with
370 pins. While all pins of these CPUs are
arranged into square arrays, the outmost square
array is short of one pin at two adjacent
corners.
2.4.2 Identifying Socket 370
Socket 370 is a CPU socket with 370 pins on
one side and 370 holes on the other. While
all these holes are arranged into square arrays,
the outmost square array is short of one hole at
two adjacent corners.
To accommodate a Socket 370 CPU, these
two special corners of the socket should match
withthe two one-pin-short corners of the CPU.

WCP-640 Components Setup

2.5 Installing DRAM (DIMMs)
The WCP-640 provides a socket for a 168-pin dual inline memory module (DIMM). The
socket uses 3.3V unbuffered synchronous DRAM (SDRAM). DIMMs are available in
capacities of 16, 32, 64, or 128 MB. The WCP-640 board can accept both regular and PC-133
SDRAM DIMMs (with or without parity). However, if a CPU with a frontside bus of higher
than 66MHz is used, the WCP-640 can only accept a PC-100/133 SDRAM DIMM.
➲To insert a DIMM:
To insert a DIMM, align the
module withthe socket key and
press down until the levers at each
end of the socket snap close up.
There is only one direction for installing a module in the socket. Do not attempt to force the
module into the socket incorrectly.
➲To remove a DIMM:
To remove a DIMM, press down
on the levers atboth end ofthe
module until the module pops out.

cleared. After clearing
the CMOS data, be sure
to againshort pins 1-2, or
the systemwill not work
properly.
➲To clear CMOS:
1. Turn off the power supply.
2. Remove the power cable from the PW connector.
3. Locate JP2 and short pins 2-3 for a fewseconds.
4. Return JP2 to its normal setting(i.e. shorting pins 1-2).
5. Connect the power cable to the PW connector.
6. Turn on the power supply.
7. Press “DEL” keyto enter BIOS Setup and specify a newpassword or CPU speed.

DiskOnChip Socket
The DiskOnChip 2000 family of products provides a single chip solid-state flash disk in a
standard 32-pin DIP package. It can be plugged directly into the socket onto the WCP-640
board, eliminating the need for mechanical disk drives, bulky ribbon cables, and connectors.
The DiskOnChip 2000 family of products is available in capacities ranging from 2MB up to
288MB, unformatted. The DiskOnChip 2000 uses the M-systems’ Flash File System
(TrueFFS) management technology that allows flash components to fullyemulate a hard disk.
