Introduction
WAFER-6820 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-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
