CHAPTER

General

Information

This chapter gives background informa­tion on the PCM-5890.

Sections include:

• Card specifications

• Card layout and dimensions

Chapter 1 General Information 1

Introduction

The PCM-5890 is an all-in-one single board Pentium computer
with an on-board PCI SVGA controller, a PCI Ethernet interface
and a PCI expansion slot. Equipped with 64 bits and local bus
architecture, the PCM-5890 releases Pentium's full potential and
provides unprecedented performance compared to current 32-bit
processor boards. The PCM-5890 offers all the functions of an
industrial computer on a single board, but fits in the space of a
5¼" floppy drive (only 5.75" x 8"). For maximum performance,
the PCM-5890 also supports 2nd level cache sized from 256 KB
to 512 KB.

On-board features include four serial ports (three RS-232 and
one RS-232/422/485), one multi-mode parallel (ECP/EPP/SPP)
port, a floppy drive controller and a keyboard/PS/2 mouse
interface. The built-in high speed PCI IDE controller supports
both PIO and bus master modes. Up to two IDE devices can be
connected, including large hard disks, CD-ROM drives, tape
backup drives and other IDE devices.

The PCM-5890 also features power management to minimize
power consumption. It complies with the “Green Function”
standard and supports three types of power saving features: Doze
mode, Standby mode and Suspend mode. In addition, the board’s
watchdog timer can automatically reset the system or generate an
interrupt in case the system stops due to a program bug or EMI.

On-board peripherals with true PCI

performance

The PCM-5890 is a highly integrated, all-in-one single board
computer. All on-board peripherals (including PCI flat panel/VGA
interface, PCI Ethernet and PCI IDE) adopt PCI technology and
operate through an internal PCI bus. Integrating a Pentium board
with PCI architecture has unleashed a revolutionary level of
performance. The PCM-5890 is the smallest and most powerful
all-in-one Pentium board available.

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.

Open Closed Closed 2-3

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 represen­tative before you make any changes.

Generally, you simply need a standard cable to make most
connections.

12 PCM-5890 User's Manual

CPU installing and upgrading

You can upgrade to a higher power Pentium CPU at any time.

Simply remove the old CPU, install the new one, and set the

jumpers for the new CPU type and speed.

Warning! Always disconnect the power cord from your

chassis when you are working on it. Do not
make connections while the power is on as
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 PC board. 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.

1. If you are upgrading the CPU, remove the old CPU from the

socket. If it is difficult to remove, you may find chip lubricant
(designed for pin-grid-array devices, PGAs) and a chip puller
helpful. Both are available at electronics hobby supply stores.

2. Plug the new CPU into the empty socket. Follow the instruc-

tions that came with the CPU or math coprocessor. If you have
no instructions, do the following: Lubricate the CPU pins with
lubricant made for PGA devices. This will make the new CPU
slide in much more easily and reduce the chance of damaging
it. Next, carefully align the CPU so it is parallel to the socket
and the notch on the corner of the CPU corresponds with the
notch on the inside of the socket. Gently slide the CPU in.
There will probably be a gap between the CPU and the connec­tor when it is fully seated - Do not push too hard!

When you install a new CPU, be sure to adjust the board settings,
such as CPU type and CPU clock. Improper settings may

damage the CPU.

Chapter 2 Installation 13

System clock setting (J10, J11, J12)

J10, J11, and J12 are used to sychronize the system clock with
the CPU type. When the board is shipped, it is set for a Pentium
75 MHz. You may need to adjust the CPU clock according to the
base CPU speed.

Installing DRAM (SIMMs)

The PCM-5890 CPU card provides two 72-pin SIMM (Single In­line Memory Module) sockets and supports either Fast Page
Mode (FPM) or Extended Data Output (EDO) DRAM with a
speed of at least 70 ns. Unlike most other CPU cards, the PCM­5890 supports both single and dual insertion into the memory
bank. Depending on the combination of modules you use, you can
install from 1 MB to 64 MB of RAM.

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.

1. Ensure that all power sources are disconnected.

2. Slip the memory module into the socket at a 45 degree angle.

3. 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 corre­spond to the circular holes on the ends of the module.

4. Repeat steps 2 and 3 for each module you install.

Chapter 2 Installation 15

Selecting cache module type (J8)

The PCM-5890 features a 2nd level memory cache that supports
both asynchronous SRAM (standard) and pipelined burst RAM
modules cache memory. The best performance can be achieved
using the pipelined burst RAM in the Pentium class system. Refer
to the table below to configure your cache module types: Syn­chronous SRAM(SYNC) or Asynchronous SRAM(ASYNC).

16 PCM-5890 User's Manual

IDE hard drive connector (CN13)

You can attach one or two Enhanced Integrated Device Electron­ics hard disk drives to the PCM-5890's internal controller.

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 CN13. 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 drive, 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 dirves. If you
install just one drive, set it as the master.

Chapter 2 Installation 17

Floppy drive connector (CN14)

You can attach up to two floppy disks to the PCM-5890's on­board 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 CN14. Make sure
that the red wire corresponds to pin one on the connector.

2. Attach the appropriate connector on th eother 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 sesire, 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.

18 PCM-5890 User's Manual

Parallel port connector (CN12)

Normally, the parallel port is used to connect the card to a printer . The
PCM-5890 includes an on-board parallel port, accessed through CN12, a 26­pin flat-cable connector. You will need an adapter cable if you use a
traditional 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-5890 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-5890 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/AT BIOS will report an error or fail during power-on
self test (POST) after a reset if the keyboard is not present. The
PCM-5890'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).

Chapter 2 Installation 19

Front panel connector (CN6)

Next you may want to install external switches to monitor and

control the PCM-5890. These features are completely optional

install them only if you need them. The front panel connector

(CN6) is an 8-pin male, dual in-line header and provides connec-

tions for a speaker, hard disk access indicator and an input switch

for resetting the card.

Speaker

The PCM-5890 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.

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

Flat panel display connector (CN4)

CN4 consists of a 44-pin, dual-in-line header. Power supplies
(+12 V, -12 V) present on CN4 depend the supply connected to
the board. Ensure that both CN7 and CN15 are connected for ±12
V power supply .

The PCM-5890 provides a bias control signal on CN4 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-5890's power is applied, the control signal is low
until just after the relevant flat panel signals are present.

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 (CN3)

CN3 is a 16-pin, dual-in-line header used for conventional CRT
displays. A simple one-to-one adapter can be used to match CN3
to a standard 15-pin D-SUB connector commonly used for VGA.

Pin assignments for CRT display connector CN3 are detailed in
Appendix C.

22 PCM-5890 User's Manual

When the PCM-5890'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 Planar EL Display .

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). The two jumpers are:

Watchdog timer enable/disable (J25)

You can enable or disable the watchdog timer by reading the card's
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.
Configure the watchdog timer to be enabled or disabled via a two­pin jumper (J25) as shown below:

System test and initialization

These routines test and initialize board hardware. If the routines
encounter an error 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-5890 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.

Chipset Features Setup

This section allows you to configure the system based on the
specific features of the installed chipset. This chipset manages
bus speeds and access to system memory resources, such as
DRAM and the external cache. It also coordinates communica­tions between the conventional ISA bus and the PCI bus. It must
be stated that these items should never need to be altered. The
default settings have been chosen because they provide the best
operating conditions for your system.

The only time you might consider making any changes would be
if you discovered that data was being lost while using your
system.

you should retain the default configuration unless advised
otherwise by your system manufacturer.

Choices are Level and Edge.

PCI IDE IRQ Map To

This allows you to configure your system to the type of IDE disk
controller in use. The more apparent difference is the type of
slot being used.

If you have equipped your system with a PCI controller, changing
this allows you to specify which slot has the controller and which
PCI interrupt (A, B, C or D) is associated with the connected hard
drives.

Remember that this setting refers to the hard disk drive itself,
rather that individual partitions. Since each IDE controller
supports two separate hard drives, you can select the INT# for
each. Again, you will note that the primary has a lower interrupt
than the secondary.

Selecting PCI Auto allows the system to automatically determine
how your IDE disk system is configured.

DEFAULTS

LOAD BIOS DEF AULTS 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

Drivers and Utilities

This chapter provides information about:

• Driver types and installation

• Software utility installation and use

Chapter 5 Flat Panel/ CRT Controller 57

Software drivers

This chapter describes the operation and installation of the software
drivers supplied on the Display Driver Diskettes that are shipped
with your VGA adapter.

Your VGA adapter is based on the CHIPS VGA Flat Panel/CRT
controller and is fully IBM VGA compatible. This controller offers a
large set of extended functions and higher resolutions. If you intend
to use your VGA adapter in standard VGA modes only, you do not
need to install any of these drivers. Since your VGA adapter is fully
compatible, it does not require any special drivers to operate in
standard modes.

The purpose of the enclosed software drivers is to take advantage of
the extended features of the CHIPS VGA Flat Panel/CRT controller.

Hardware configuration

Some of the high-resolution drivers provided in this package will
work only in certain system configurations. If a driver does not
display correctly, try the following:

1. Change the display controller to CRT-only mode, rather than flat
panel or simultaneous display mode. Some high-resolution
drivers will display correctly only in CRT mode.

2. If a high-resolution mode is not supported on your system, try
using a lower-resolution mode. For example, 1024 x 768 mode
will not work on some systems, but 800 x 600 mode is supported
on most.

58 PCM-5890 User's Manual

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

• Know how to format a floppy disk

If you are uncertain about any of these concepts, please refer to the
DOS or OS/2 user reference guides for more information, before
you proceed with the installation.

Before you begin

Before you begin the driver software installation, you should make
backup copies of the Display Driver Diskettes. Store the original
disks in a safe place.

Make sure you know the version of the application for which you are
installing drivers. Your Display Driver Diskettes contain drivers for
several versions of certain applications. For your driver to operate
properly, you must install the driver for your version of the applica­tion program.

Programming the Watch­dog Timer

The PCM-5890 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 67

Jumpers J23, J24, and J25 control the watchdog settings. The
default configuration of the timer is enabled with system reset.

T o 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 watch-

dog
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 com-

plete

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

2090 RETURN

Modules

This appendix gives instructions for
installing PC/104 modules.

Appendix B Installing PC/104 Modules 69

Installing PC/104 modules

The PCM-5890'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-3110 PCMCIA Module

• PCM-3111 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-5890 is quick and simple.

The following steps show how to mount the PC/104 modules:

1. Remove the PCM-5890 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-5890 and the PC/104
module are both female. For this reason, you may need to use
the "male-male" adapter included with the PCM-5890 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.
