3.1 Introduction

The PCM-5821 is a highly reliable single board computer based on the
NS GX1 300MHz CPU. It offers built-in functionality comparable to
a complete industrial PC system, including a VGA/LCD controller,
network communications, compact flash diak in a small 8" x 5.75"
form factor.
For maximum performance, the PCM-5821 also supports an SDRAM
SODIMM socket that can accept up to 128 MB memory. On-board
features include an Ethernet interface, audio interface, socket for
Compact Flash Card, Enhanced IDE interface with up to Ultra DMA
transfer protocol, one parallel port, four serial ports (RS-232 and RS-
232/422/485) with DB-9 connector, and a mini-DIN PS/2 keyboard/
mouse interface. An SVGA/LCD display controller (LCD, and CRT
displays) allows LCD screen resolutions up to 800 x 600 @ 256 K
colors.
The PCM-5821 complies with the "Green Function" standard and
supports three types of power saving features: Normal, Doze, and
Sleep modes.
The display type configuration is done through software. A single
Flash chip holds the system BIOS and the VGA BIOS. This minimizes
the number of chips and eases configuration. You can change the
display BIOS simply by programming the Flash chip.
It also offers faster data access and longer MTBF than mechanical disk
drives and is an ideal solution for critical commercial or industrial
applications. The watchdog timer ensures the system will be reset if it
stops due to a program bug or EMI problem.
