Introduction
The PCM-4890 is an enhanced, all-in-one single board 486 comput-
er with an on-board Ethernet interface, local-bus SVGA controller.
The PCM-4890 offers all the functions of an AT-compatible
industrial computer on a single board, but it fits in the space of a
5¼"floppydrive (only 5.75" x 8"). For maximum performance,the
PCM-4890 also supports 2nd level cache sizes from 128 KB to 512
KB(32 KBx8,64KBx8,or 128KBx 8).
On-board features include four 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.
The PCM-4890 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 function. 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, or use ISA
peripheral cards via the on-board ISA expansion slot.

Setting jumpers
You configure your card to match the needs of your application by
setting jumpers. A jumper is the simplest kind of electric switch. It
consists of two metal pins and a small metal clip (often protected
by a plastic cover) that slides over the pins to connect them. To
“close” a jumper you connect the pins with the clip. To “open” a
jumper you remove the clip. Sometimes a jumper will have three
pins, labeled 1, 2, and 3. In this case you would connect either pins
1 and 2 or 2 and 3.
The jumper settings are schematically depicted in this manual as
follows:
A pair of needle-nose pliers may be helpful when working with
jumpers.
If you have any doubts about the best hardware configuration for
your application, contact your local distributor or sales representa-
tive before you make any changes.
Generally, you simply need a jumper to make most connections.

Safety precautions
Warning! Always completely disconnect the power cord
from your chassis whenever you are working on it.
Do not make connections while the power is on
because sensitive electronic components can be
damagedbythe suddenrush ofpower.Only
experiencedelectronicspersonnelshouldopen
the PC chassis.
Caution! Always ground yourself to remove any static
chargebeforetouchingtheCPUcard.Modern
electronic devices are very sensitive to static
electric charges. Use a grounding wrist strap at all
times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag when they are not in the chassis.
Installing the CPU
ThePCM-4890 all-in-one CPU module supports most 486CPUs.
The system's performance depends on the CPU you choose. You
can install or upgrade the CPU in the board's PGA socket by
following the procedures outlined below. If your system has an
existing CPU, you need to remove it before installing the new CPU.
Removing a CPU
1. Disconnect power from the chassis, and unplug all connections
to the CPU card. Then, remove the CPU card from the chassis
by following the instructions in the user's manual for your
chassis.
2. Lift the CPU out of the PGA socket. The old chip may be
difficult to remove. You may find spray chip lubricant, designed
for pin-grid-array (PGA) devices, and a chip puller helpful.
These are available at electronics hobbyists' supply stores.
