2PCM-5820 Series User's Manual
1.1 Introduction
The PCM-5820 Series is the ultimate cost-effective solution for
limited space applications. It offers all the functions of an
AT-compatible industrial computer on a single board and only
occupies the space of a 3½" hard drive. The PCM-5820/5820L
comes with an embedded high-performance GXM-233 processor
on-board. The PCM-5820E/5820EL comes with a low power
GXM-200 processor on-board. For maximum performance, the
PCM-5820/5820L 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, two serial ports
(RS-232 and RS-232/422/485) with DB-9 connector as COM1,
and a mini-DIN PS/2 keyboard/mouse interface. An SVGA/LCD
display controller (LCD, and CRT displays) allows LCD screen
resolutions up to 1024 x 768 and CRT resolutions up to 1280 x
1024 @ 16 colors. Supports LVDS interface for long distance
LCD panel signal transmission and EMI protection add-ons.
The PCM-5820/5820L 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.
If you need any additional functions, the PCM-5820/5820L has a
PC/104 connector for future upgrades.
