Features - Advantech PCM-4862 Manual

The PCM-4862 is an enhanced, all-in-one single board 486
computer with an on-board Ethernet interface, local-bus SVGA
controller and solid state disk. The PCM-4862 offers all the
functions of an AT-compatible industrial computer on a single
board, but it fits in the space of a 5¼" floppy drive (only 5.75" x
8"). For maximum performance, the PCM-4862 also supports 2nd
level cache sizes from 128 KB to 512 KB (32 KB x 8, 64 KB x 8,
or 128 KB x 8).
On-board features include two serial ports (RS-232 and RS-232/
422/485), one parallel port, an enhanced IDE hard-drive controller
(for up to two drives), a floppy-drive controller and a keyboard/PS/
2 mouse interface. The board's watchdog timer can automatically
reset the system or generate an interrupt if it stops due to a program
bug or EMI problem.
An on-board solid state disk (SSD) emulates a floppy drive using
EPROM or Flash memory devices. You access the SSD using
standard DOS commands or BIOS I/O. The system can even boot
from the SSD. Disk capacity is up to 1.44 MB, depending on the
size of the memory chips. If you use Flash memory, you can read
and write to the disk just like a floppy. If you use EPROM, the disk
is read-only and you must program the chips with an EPROM
programmer.
The PCM-4862 also complies with the "Green Function" standard
and supports three types of power saving features: Doze mode,
Standby mode, and Suspend mode.
All display and Ethernet configuration is done through software. A
single Flash chip holds the system BIOS, VGA BIOS and the
network boot ROM image. This minimizes the number of chips and
eases configuration. You can change the display BIOS or install a
boot ROM simply by programming the Flash chip.
If you need any additional functions, you can add up to six
industry-standard PC/104 expansion modules. For those who
require special functions, we have developed a PC/104 to ISA
adaptor so you can use your standard ISA card.
