This chapter gives background informa­tion on the PCM-4890.

Sections include:

• Card specifications

• Card layout and dimensions

Chapter 1 General Information 1

Introduction

The PCM-4890 is an enhanced, all-in-one single board 486 comput­er 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" floppy drive (only 5.75" x 8"). For maximum performance, the
PCM-4890 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 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. T o “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.

Open Closed Closed 2-3

The jumper settings are schematically depicted in this manual as
follows:

Open Closed Closed 2-3

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 representa­tive before you make any changes.

Generally, you simply need a jumper to make most connections.

Chapter 2 Installation 11

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.

Installing the CPU

The PCM-4890 all-in-one CPU module supports most 486 CPUs.
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. Y ou 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.

12 PCM-4890 User's Manual

Installing a CPU

T o install the CPU, follow the instructions that came with it. If no
documentation was provided, the general procedures for installing
a CPU are outlined below:

1 . Lubricate the pins on the CPU with lubricant for PGA devices.

This makes the CPU slide in much easier and greatly reduces
the chance of damaging the pins and other components.

2 . Carefully align the CPU so that it is parallel to the socket. Make

sure that the notch on the corner of the CPU matches the notch
on the inside of the socket.

3 . Gently push the CPU into the socket. There will probably be a

small gap between the CPU and the socket even when it is fully
seated. DO NOT USE EXCESSIVE FORCE!

When you install a new CPU, you may have to adjust other
settings on the board, such as CPU type, CPU clock, and PCI
speed, to accommodate it. Make sure that the settings are correct
for your CPU. Improper settings may damage the CPU.

Installing DRAM (SIMMs)

Y ou can install anywhere from 1 MB to 32 MB of on-board DRAM
memory using 1, 2, 4, 8 or 16 MB 72-pin SIMMs (Single In-Line
Memory Modules). Access time should be 70 nsec. or less.

Memory installs in two banks composed of one SIMM socket each.
The banks are designated as Bank0 and Bank1. See the figure on
page 10 for help identifying the banks. Y ou must fill Bank0 first. If
you fill both banks, the memory capacity of both SIMMs should be
the same.

Installing SIMMs

NOTE: The modules can only fit into a socket one way.

Their chips must face the CPU , and their gold
pins must point down into the SIMM socket.

The procedure for installing SIMMs appears below. Please follow
these steps carefully.

1 . Ensure that all power supplies to the system are switched Off.
2 . Locate the board's memory banks, shown in the figure on

IDE hard drive connector (CN9)

The built-in Enhanced IDE (Integrated Device Electronics) control­ler supports up to two IDE devices, including CD-ROM drives, tape
backup drives, a large hard disk drive and other IDE devices. It also
supports faster data transfer rates and allows the IDE hard disk
drive to exceed 528 MB.

Connecting the hard drive

Connecting drives is done in a daisy-chain fashion and requires
one of two cables, depending on the drive size. 1.8" and 2.5" drives
need a 1 x 44-pin to 2 x 44-pin flat-cable connector. 3.5" drives use a
1 x 44-pin to 2 x 40-pin connector.

Wire number 1 on the cable is red or blue, and the other wires are
gray.

1 . Connect one end of the cable to CN9. Make sure that the red (or

blue) wire corresponds to pin 1 on the connector, which is
labeled on the board (on the right side).

2 . Plug the other end of the cable to the Enhanced IDE hard drive,

with pin 1 on the cable corresponding to pin 1 on the hard
drive. (See your hard drive's documentation for the location of

the connector.)
Connect a second drive as described above.
Unlike floppy drives, IDE hard drives can connect to either end of

the cable. If you install two drives, you will need to set one as the
master and one as the slave by using jumpers on the drives. If you
install just one drive, set it as the master.

18 PCM-4890 User's Manual

Floppy drive connector (CN15)

You can attach up to two floppy disks to the PCM-4890's on-board
controller. You can use any combination of 5¼" (360 KB and 1.2
MB) and/or 3½" (720 KB, 1.44 MB, and 2.88 MB) drives.

A 34-pin daisy-chain drive connector cable is required for a dual­drive system. On one end of the cable is a 34-pin flat-cable connec­tor. On the other end are two sets of floppy disk drive connectors.
Each set consists of a 34-pin flat-cable connector (usually used for
3½" drives) and a printed-circuit board connector (usually used for
5¼" drives).

Connecting the floppy drive

1 . Plug the 34-pin flat-cable connector into CN15. Make sure that

the red wire corresponds to pin one on the connector.

2. Attach the appropriate connector on the other end of the cable
to the floppy drive(s). You can use only one connector in the
set. The set on the end (after the twist in the cable) connects to
the A: drive. The set in the middle connects to the B: drive.

3 . If you are connecting a 5¼" floppy drive, line up the slot in the

printed circuit board with the blocked-off part of the cable
connector.
If you are connecting a 3½" floppy drive, you may have trouble
determining which pin is pin number one. Look for a number
printed on the circuit board indicating pin number one. Also,
the connector on the floppy drive connector may have a slot.
When the slot is up, pin number one should be on the right.
Check the documentation that came with the drive for more
information.

If you desire, connect the B: drive to the connectors in the
middle of the cable as described above.

If you need to make your own cable, you can find the pin assign­ments for the card’s connector in Appendix C.

Chapter 2 Installation 19

Parallel port connector (CN12)

Normally the parallel port is used to connect the card to a printer.
The PCM-4890 includes an on-board parallel port, accessed
through CN12, a 26-pin flat-cable connector. You will need an
adapter cable if you use a DB-25 connector. The cable has a 26-pin
connector on one end and a DB-25 connector on the other.

Parallel port IRQ

The PCM-4890 supports one parallel port. The port is designated
as LPT1 and can be disabled or changed to LPT2 or LPT3 in the
system BIOS setup.

Keyboard and PS/2 connector (CN8)

The PCM-4890 board provides a keyboard connector which
supports both a keyboard and a PS/2 style mouse. In most cases,
especially in embedded applications, a keyboard is not used. The
standard PC/A T BIOS will report an error or fail during power-on
self test (POST) after a reset if the keyboard is not present. The
PCM-4890's BIOS standard setup menu allows you to select "All,
But Keyboard" under the "Halt On" selection. This allows no­keyboard operation in embedded system applications without the
system halting under POST (power-on-self-test).

20 PCM-4890 User's Manual

Front panel connector (CN5)

Next you may want to install external switches to monitor and
control the PCM-4890. These features are completely optional —
install them only if you need them. The front panel connector (CN5)
is an 8-pin male, dual in-line header and provides connections for a
speaker, hard disk access indicator and an input switch for reset­ting the card.

Speaker

The PCM-4890 can drive an 8 W speaker at 0.5 watts. Ensure that
alternatives to this specification do not overload the card.

LED interface

The front panel LED indicator for hard disk access is an active low
signal (24 mA sink rate).

Reset switch

If you install a reset switch, it should be a open single pole switch.
Momentarily pressing the switch will activate a reset. The switch
should be rated for 10 mA, 5 V .

VGA interface connections

The PCM-4890's SVGA interface can drive conventional CRT
displays and is capable of driving a wide range of flat panel
displays, including electroluminescent (EL), gas plasma, passive
LCD and active LCD displays. The card has two connectors to
support these displays, one for standard CRT VGA monitors and
one for flat panel displays.

CRT display connector (CN1)

CN1 is a 16-pin, dual-in-line header used for conventional CRT
displays. A simple one-to-one adapter can be used to match CN1 to
a standard 15-pin D-SUB connector commonly used for VGA.

Pin assignments for CRT display connector CN1 are detailed in
Appendix C.

Flat panel display connector (CN2)

CN2 consists of a 44-pin, dual-in-line header. Power supplies (+12 V,

-12 V) present on CN2 depend the supply connected to the board.

Ensure that both CN7 and CN10 are connected for
±12 V power supply.

Chapter 2 Installation 23

The PCM-4890 provides a bias control signal on CN2 which can be
used to control the LCD bias voltage. It is recommended that the
LCD bias voltage not be applied to the panel until the logic supply
voltage (+5 V) and panel video signals are stable. Under normal
operation the control signal (ENAVEE) is active high. When the
PCM-4890's power is applied, the control signal is low until just
after the relevant flat panel signals are present.

Configuration of the VGA interface is done completely via the
software utility . You don't have to set any jumpers. Refer to Chapter
3 for software setup details.

Refer to Chapter 3 for details on connecting the four standard
LCD's: Sharp LM64183P , T oshiba L TM09C016, Sharp 64C142, and

Ethernet configuration

The PCM-4890 is equipped with a high performance 16-bit Ethernet
interface which is fully compliant with IEEE 802.3 10Mbps CSMA/
CD standards. It is supported by all major network operating
systems and is 100% Novell NE-2000 compatible.

Configuration of the Ethernet is very easy and can be done via the
RSET8019.EXE program included on the utility disk. This program
enables you to: view the current Ethernet configuration, to recon­figure the Ethernet interface (IRQ, I/O address, etc.), and to execute
useful diagnostic functions. (See Chapter 3 for detailed informa­tion)

The RSET8019.EXE program provides two ways to configure the
Ethernet interface. Configuration can be done automatically when
you choose PNP (plug and play) option; or, when you choose the
Jumperless option, the following IRQ and I/O address settings are
available.

10BASE-T connector (CN13)

10BASE-T connects to the PCM-4890 via an adapter cable to a 10­pin polarized header (CN13). For 10BASE-T RJ-45 operation, an
adapter cable converting CN13 into a standard RJ-45 jack is
required.

Network boot

The Network Boot feature can be utilized by incorporating the Boot
ROM image files for the appropriate network operating system. The
Boot ROM BIOS files are available from your supplier. They can be
programmed into the BIOS, similar to the VGA BIOS file, using the
A WDFLASH.EXE program detailed in Chapter 3.

Watchdog timer configuration

An on-board watchdog timer reduces the chance of disruptions
which EMP (electro-magnetic pulse) interference can cause. This is
an invaluable protective device for standalone or unmanned
applications. Setup involves two jumpers and running the control
software (refer to Appendix A).

Watchdog timer enable/disable

You can enable or disable the watchdog timer by reading the
I/O ports with your program. Read address 443 hex to enable and
refresh the watchdog or address 043 to disable the watchdog. For
information on programming the watchdog timer see Appendix A.

Watchdog timer action (J19, J20)

When the watchdog timer activates (CPU processing has come to a
halt), it can reset the system or generate an interrupt on IRQ15.
This can be set via two 2-pin jumpers (J19, J20) as shown below:

Chapter 4 Award BIOS Setup 39

System test and initialization

These routines test and initialize board hardware. If the routines
encounter an error in during the tests, you will either hear a few
short beeps or see an error message on the screen. There are two
kinds of errors: fatal and non-fatal. The system can usually
continue the boot up sequence with non-fatal errors. Non-fatal
error messages usually appear on the screen along with the
following instructions:

Press <F1> to RESUME

Write down the message and press the F1 key to continue the
bootup sequence.

System configuration verification

These routines check the current system configuration against the
values stored in the card’s CMOS memory. If they don’t match,
the program outputs an error message. You will then need to run
the BIOS setup program to set the configuration information in
memory.

There are three situations in which you will need to change the
CMOS settings:

1. You are starting your system for the first time

2. You have changed the hardware attached to your system

3. The CMOS memory has lost power and the configuration
information has been erased.

The PCM-4890’s CMOS memory has an integral lithium battery
backup. The battery backup should last ten years in normal
service, but when it finally runs down, you will need to replace the
complete unit.

LOAD BIOS DEFAULTS loads the default system values directly
from ROM. The BIOS DEFAULTS provides the most stable
settings, though they do not provide optimal performance. LOAD
SETUP DEFAULTS, on the other hand, provides for maximum
system performance. If the stored record created by the Setup

SVGA Setup

The PCM-4890 features an on-board flat
panel/VGA interface. This chapter
provides instructions for installing and
operating the software drivers on the
included display driver diskette.

Chapter 5 SVGA Setup 49

Simultaneous display mode

The 65545 VGA BIOS supports monochrome LCD, EL, color
TFT and STN LCD flat panel displays. It also supports interlaced
and non-interlaced analog monitors (VGA color and VGA
monochrome) in high-resolution modes while maintaining
complete IBM VGA compatibility. Digital monitors (i.e. MDA,
CGA, and EGA) are NOT supported. Multiple frequency (multi­sync) monitors are supported as analog monitors.

Both CRT and panel displays can be used simultaneously. The
PCM-4890 can be set in one of three configurations: on a CRT, on
a flat panel display, or on both simultaneously. The system is
initially set to simultaneous display mode. In the utility diskette,
there are three .COM files which can be used to select the display.
Simply type the filename at the DOS prompt:

CT.COM Enables CRT display only
FP.COM Enables panel display only
SM.COM Enables both displays at the same time.

Sleep mode

The display driver diskette contains two files that support sleep
mode. Simply type the filename at the DOS prompt:

ON.COM switches to normal display mode.
OFF.COM switches to sleep mode.

Necessary prerequisites

The instructions in this manual assume that you understand
elementary concepts of MS-DOS and the IBM Personal Computer.
Before you attempt to install any driver or utility you should:
know how to copy files from a floppy disk to a directory on the
hard disk, understand the MS-DOS directory structure, and know
how to format a floppy disk. If you are uncertain about any of
these concepts, please refer to the DOS or Windows user reference
guides for more information before you proceed with the installa­tion.

Before you begin

Before you begin installing software drivers, you should make a
backup copy of the display driver diskette and store the original in
a safe place. The display driver diskette contains drivers for
several versions of certain applications. You must install the
correct version in order for the driver to work properly so make
sure you know which version of the application you have.

APPENDIX

A

Programming the

Watchdog Timer

The PCM-4890 is equipped with a
watchdog timer that resets the CPU or
generates an interrupt if processing comes
to a standstill for whatever reason. This
feature ensures system reliability in
industrial standalone, or unmanned,
environments.

Appendix A Programming the Watchdog Timer 65

Jumpers J19 and J20 control the watchdog settings. The default
configuration of the timer is enabled with system reset.

To enable the watchdog timer, you must write a program which
reads I/O port address 443 (hex) at regular intervals. The first time
your program reads the port, it enables the watchdog timer. After
that, your program must read the port at time interval of less than

1.6 seconds, otherwise the watchdog timer will activate and reset
the CPU or generate an interrupt on IRQ15. When you want to
disable the watchdog timer, your program should read I/O port
043 (hex).

If CPU processing comes to a standstill because of EMI or a
software bug, your program's signals to I/O port address 443 to the
timer will be interrupted. The timer will then automatically reset
the CPU or invoke an IRQ, and data processing will continue
normally.

You must write your program so that it reads I/O port address 443
at an interval shorter than the timer's preset interval. The timer's
intervals have a tolerance of ±30%, so you should program an
instruction that will refresh the timer about every second.

The following program shows how you might program the
watchdog timer in BASIC:

10 REM Watchdog timer example program
20 X=INP (&H443) REM Enable and refresh the watchdog
30 GOSUB 1000 REM Task #1, takes 1 second to complete
40 X=INP (&H443) REM Refresh the watchdog
50 GOSUB 2000 REM Task #2, takes 1 second to complete
60 X=INP (&H043) REM Disable the watchdog
70 END
1000 REM Subroutine #1, takes 1 second to complete

1070 RETURN
2000 REM Subroutine #2, takes 1 second to complete

Installing PC/104 modules

The PCM-4890's PC/104 connectors give you the flexibility to
attach PC/104 expansion modules. These modules perform the
functions of traditional plug-in expansion cards, but save space
and valuable slots. Modules include:

• PCM-3290 GPS Module

• PCM-3810 Solid State Disk Module

• PCM-3820 High Density Flash Disk Module

• PCM-31 10 PCMCIA Module

• PCM-31 11 Secondary PCMCIA Module

• PCM-3610 Isolated RS-232 and RS-422/485 Module

• PCM-3660 Ethernet Module

• PCM-3718 30 KHz A/D Module

• PCM-3724 48-Channel DIO Module

• PCM-3640 4-Port RS-232 Module

• PCM-3680 Dual Port CAN Module
Installing these modules on the PCM-4890 is quick and simple. The

following steps show how to mount the PC/104 modules:
1 . Remove the PCM-4890 from your system paying particular

attention to the safety instructions already mentioned above.

2 . Make any jumper or link changes required to the CPU card now.

Once the PC/104 module is mounted you may have difficulty in
accessing these.

3 . Normal PC/104 modules have male connectors and mount

directly onto the main card. However, to ensure better bus
matching, the connectors on the PCM-4890 and the PC/104
module are both female. For this reason, you may need to use
the "male-male" adapter included with the PCM-4890 in order to
properly connect your PC/104 module. (Refer to the diagram on
the following page.)

4 . Mount the PC/104 module onto the CPU card by pressing the

module firmly but carefully onto the mounting connectors.

5 . Secure the PC/104 module onto the CPU card using the four

mounting spacers and srews.
