Introduction
The PCM-4894 is an all-in-one single board 486 computer with
an onboard flat panel/CRT SVGA controller and PCI Ether-
net interface. It offers all the functions of an industrial comput-
er and its display capabilities on a single board, but fits in the
space of a 5.25" floppy drive (only 5.75" x 8"). This means the
PCM-4894 is your absolute best solution for embedded applica-
tions.
The onboard PCI-bus, flat panel/CRT SVGA controller uses the
CHIPS 65550 chipset with up to 2 MB of video memory (on-
board 1MB). This chipset, used with the local PCI-bus, enables
32-bit graphic throughput at up to 33 MHz. Excellent for display-
intensive applications, it supports various LCD types including
TFT,STN,B/W,and EL.
The onboard Ethernet Realtek RTL 8029AS PCI bus Ethernet
controller supports remote boot ROM functions.
The PCM-4894 supports the M-Systems DiskOnChip 2000
(optional) which is a new generation of high performance single-
chip Flash Disk. It provides a Flash Disk (as a BIOS expansion)
which does not require any bus, slots, or connectors. It is also the
optimal solution for Single Board Computers because of its small
size, easy integration, plug-and-play functionality, and its low
power consumption. The DiskOnChip is available in capacities
from 2MB to 72MB and fits in a standard 32-pin DIP socket.
Another feature of the PCM-4894 is the inclusion of a high
speed, local bus IDE controller. This controller supports (through
ATA PIO) mode 3 and mode 4 hard disks, enabling data transfer
rates in excess of 11 MB/second. Up to two IDE devices can be
connected, including large hard disks, CD-ROM drives, tape
backup drives, or other IDE devices. The built-in, enhanced IDE
controller provides a 4-layer, 32-bit, posted write buffer and a 4-
layer, 32-bit read-prefetch buffer to boost IDE performance.

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 represen-
tative before you make any changes.

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 damaged by the sudden rush of power. Only
experienced electronics personnel should open
the PC chassis.
Caution! Always ground yourself to remove any static
charge before touching the CPU card. 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.

14 PCM-4894 User Manual
Installing DRAM (SIMMs)
The PCM-4894 CPU card provides two 72-pin SIMM (Single In-
line Memory Module) sockets and supports between 4MB and
64MB.
When installing SIMMs, make sure that Bank 1 is filled first.
Installing SIMMs
Note: that the modules can only fit into a socket one way.
1. Insert the memory module into the socket at a moderate angle.
2. Push the module toward the vertical posts at both ends of the
socket until the module is upright and the retaining clips at
both ends of the module click into place. When positioned
correctly, the pins on top of the vertical posts should corre-
spond to the circular holes on the ends of the module.
3. Repeat steps 1 and 2 for each module you install.
Removing SIMMs
If you need to remove a SIMM, follow the procedures below:
1. Supporting the SIMM with a finger, use a pen or a similarly
shaped object and press one retaining clip straight down.
2. Repeat for the other side. When released, the retaining clips
will push the SIMM up and out of its upright position.
3. Carefully pull the SIMM out of the socket with your fingers.
4. Repeat the above steps for each module you remove.
