Introduction
WAFER-6820 is designed for limited space applications with only the
size of a 3½" hard drive. Itsupports the full functions of an AT-compatible
industrial computer on a single board. The WAFER-6820 is equipped with a
low-power consumption and high performance Transmeta TM3200
processor on board. It also contains an SDRAM SODIMM socket that can
support up to 128MB memory.
The WAFER-6820 provides an Ethernet interface, audio interface,
Compact Flash Type II, EIDE interface, one parallel port, one serial port
RS-232, one serial port RS-232/422/485 with auto-direction, 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 1024 x 768 and CRT resolutions up to 1280
x 1024 @ 16 colors. The display type is configured by software utility. The
Flash ROM contains both the system BIOS and the VGA BIOS.
Reprogramming the Flash ROM could do the modification, in case of
necessary.
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

2
your wish.
Finally, one PC/104 connector is included for the future application you
will need.
Notes:
The Transmeta Crusoe™ TM3200 will occupy 16MB memory space to
save its CMS code temporally. So we must indicate the memory type for
Tramsmeta Crusoe™ TM3200. Because this point, we will attaché one
128MB SDRAM module that we approved in the package.

Installation
This chapter describes how to install the WAFER-6820. At first, the
layout of WAFER-6820 is shown, and the unpacking information
that you should be careful is described. The jumpers and switches
setting for the WAFER-6820's configuration, such as watchdog
timer, are also included.

2.3 Unpacking
Your WAFER-6820 Single Board Computer contains sensitive
electronic components that can be easily damaged by static
electricity.
In this section, we describe the precautions you should take while
unpacking, as well as during installation. It is very important that the
instructions be followed correctly, to avoid static damage, and to
successfully install the board.
The system board should be done on a grounded anti-static mat.
The operator should be wearing an anti-static wristband, grounded
at the same point as the anti-static mat.
Inspect the cardboard carton for obvious damage. Shipping and
handling may cause damage to your board. Be sure there are no
shipping and handing damages on the board before processing.
After opening the cardboard carton, exact the system board and
place it only on a grounded anti-static surface component side up.
Again inspect the board for damage. Press down on all the
docketed IC's to make sure that they are properly seated.
Do this only with the board place on a firm flat surface.
Note: DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN
DAMAGED.
You are now ready to install your WAFER-6820 Single Board
Computer.

2.4 Clear CMOS Setup (J2)
If want 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 J2 pin 2-3 about 3 seconds, then open again. Set back to
normal operation mode, close pin 1-2.

2.9 COM2 PIN8 Setting (J6)
In the RS232 mode, the COM2 (CN15) can supply +5V or +12V
power to the serial devices via RI pin (Pin 8) of the COM port
connector. The maximal 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 supply to the board.

The COM2 (CN15) can be set to RS-232 or RS-422/485 for industrial
field site application. Moreover when this port was set to the RS-485
mode, the board equipped with auto-direction IC will automatically
sense 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.

Rreading port 443H enables the Watch-Dog Timer. It should be re-
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. Reading port 043/843H disables the
watchdog Timer. Refer to Appendix A for more detailed information on
Watchdog Timer
