1.1 ntroduction
The PCM-5825 is the ultimate cost-effective solution for limited
space applications. It is a new NS Geode 3.5" Biscuit PC with
4COM ports and 1-62sec Watchdog timer. It offers all the functions
of an AT-compatible industrial computer on a single board and
only occupies 3½" on a hard drive. The PCM-5825 comes with an
embedded high-performance GX1-300 or GX1-233 processor on-
board. For maximum performance, the PCM-5825 Series also
support an SDRAM SODIMM socket that can accept up to 256
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 (3 x
RS-232 and 1 x RS 232/422/485) with DB-9 connector as COM1, and
a mini-DIN PS/2 keyboard/mouse interface. A SVGA/LCD display
controller (LCD, and CRT displays) allows LCD screen resolutions
of up to 1024 x 768 and CRT resolutions of up to 1280 x 1024 @ 16
colors.
The PCM-5825 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-5825 has a PC/104
connector for future upgrades.
