CHAPTER

General Information

This chapter gives background informa­tion on the PCM-4823/4823L.

Sections include:

• Card specifications

• Card layout and dimensions

1.1 Introduction

The PCM-4823/4823L is the ultimate cost-effective solution for
limited space applications. It offers all the functions of an AT­compatible industrial computer on a single board and only occu­pies the space of a 3 1/2" hard drive. The PCM-4823/4823L
comes with an embedded high-performance 5x86 processor and
audio on-board. For maximum performance, the PCM-4823/
4823L also supports an EDO/FPM DRAM SIMM socket that can
accept up to 32 MB memory.

On-board features include an Ethernet interface, support for a VL­Bus Enhanced IDE interface with up to Mode 3 transfer protocol,
one parallel port, two serial ports (RS-232 and RS-232/422/485)
with DB-9 connector as COM1 and a mini-DIN PS/2 keyboard/
mouse interface. A local bus SVGA/LCD display controller (LCD,
EL and CRT displays) allows LCD screen resolutions up to 1024 x
768 and CRT resolutions up to 1280 x 1024 @ 16 colors
(PCM-4823 only).

The PCM-4823/4823L complies with the "Green Function"
standard and supports three types of power saving features:
Normal, Doze, and Sleep modes.

The display type configuration is done through software. A single
Flash chip holds the system BIOS and the VGA BIOS. This
minimizes the number of chips and eases configuration. You can
change the display BIOS simply by programming the Flash chip.

If you need any additional functions, the PCM-4823/4823L has a
PC/104 connector for future upgrades.

2.4 Setting jumpers

You may configure your card to match the needs of your applica­tion by setting jumpers. A jumper is the simplest kind of electrical
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:

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 standard cable to make most connec­tions.

2.5 Safety precautions

Warning! Always completely disconnect the power cord from

your board 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.

Caution! Always ground yourself to remove any static

charge before touching the 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 static­dissipative surface or in a static-shielded bag
when they are not in the chassis.

2.6 Installing DRAM (SIMMs)

Y ou can install anywhere from 1 MB to 32 MB of on-board DRAM
memory using 1, 2, 4, 8, 16 or 32 MB 72-pin SIMMs (Single In-Line
Memory Modules). DRAM access time ≤ 60 ns.

2.6.1 Installing SIMMs

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

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. Install the SIMM card. Install the SIMM so that its gold pins
point down into the SIMM socket.

3 . Slip the SIMM into the socket at a 45 degree angle and carefully

fit the bottom of the card against the connectors.

4 . Gently push the SIMM into a perpendicular position until the

clips on the ends of the SIMM sockets snap into place.

5. Check to ensure that the SIMM is correctly seated and all
connector contacts touch. The SIMM should not move around
in its socket.

Chapter 2 Installation 15

2.7 IDE hard drive connector (CN7)

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.

2.7.1 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 CN7. 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.

16 PCM-4823/4823L User's Manual

2.8 Keyboard and PS/2 mouse connector (CN13)

The PCM-4823/4823L board provides a mini-DIN 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-4823/4823L board's BIOS standard setup menu
allows you to select "All, But Keyboard" under the "Halt On"
selection. This allows no-keyboard operation in embedded system
applications without the system halting under POST (power-on­self-test).

2.9 Power connector (CN11)

2.9.1 Main power connector, +5V, +12V (CN11)

Supplies main power to the PCM-4823/4823L (+5 V) and devices
that require +12 V .

2.10 IR connector (CN8)

This connector supports the optional wireless infrared transmitting
and receiving module. This module mounts on the system case.
You must configure the setting through BIOS setup.

Chapter 2 Installation 17

2.11 Serial ports (CN12, CN9)

The PCM-4823/4823L offers two serial ports: one RS-232 and one
RS-232/422/485. These ports let you connect to serial devices (a
mouse, printers, etc.) or a communication network.

2.11.1 COM1 RS-232 port (CN12)

The serial port connectors are mounted on the bottom edge of the
card. The 9-pin, D-SUB connector to the left of the card is the RS­232 port.

2.11.2 COM2 RS-232/422/485 selection (CN9)

The secondary port located above COM1, consists of a 14-pin,
dual-in-line, male header and can be configured to operate in RS­232, RS-422, or RS-485 mode. This is done via J6.

2.12 VGA interface connections

The PCM-4823/4823L board'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.

2.12.1 CRT display connector (CN14)

CN14 is a 15-pin, D-SUB connector commonly used for convention­al CRT displays.

Pin assignments for CRT display connector CN15 are detailed in
Appendix A.

2.12.2 Flat panel display connector (CN6)

CN6 consists of a 44-pin, dual-in-line header.
The PCM-4823/4823L provides a bias control signal on CN6 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-4823/4823L board's power is applied, the control signal is
low until just after the relevant flat panel signals are present.

Configuration of the LCD type is done completely via the software
utility. You do not 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 TM10C042, Sharp 64C142, and
Planar EL Display .

CHAPTER

Award BIOS Setup

This chapter describes how to set BIOS
configuration data.

4.1 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.

4.1.1 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-4823/4823L board's CMOS memory has an integrated
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.

Chapter 5 SVGA Setup 55

5.8.5 Installation notes

1. During the installation of this driver, DISPLAY.LOG and

DSPINSTL.LOG files are created in \OS2\INST ALL directory.
These files identify the OS/2 system files that were updated and
indicate whether the installation was successful. The
DISPLA Y.LOG file also contains a string which identifies the
version of driver that was installed. This information may be
important when reporting an installation problem.

2. During installation, DSPINSTL will invoke the SVGA Configu-

ration program SVGA.EXE to determine the hardware configu­ration, and create the file \OS2\INST ALL\SVGADATA.PMI. If
this file is not created, the adapter will not be supported. When
this step is done, the display will be blanked, and you may see a
series of flashes on the display , and what appears to be a “cor­rupted” display. This is normal, as the configuration process is
doing V ideo BIOS mode sets to determine which screen resolu­tions BIOS supports. This configuration information is then used
to provide the System-Settings Resolution and Refresh selec­tions.

Programming the
Watchdog Timer

This appendix contains information
of a detailed or specialized nature.
It includes:

The PCM-4823/4823L Rev. B 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.

D

APPENDIX

Appendix D Programming the Watchdog Timer 77

D.1 Programming the Watchdog timer

T o enable the watchdog timer , you must write a program which first
writes to the I/O address + 443(hex) and then reads from that
address at regular intervals. The first time your program writes to
the port, it enables the watchdog timer. After that, your program
must read the port during a time interval of less than 1.6 seconds,
otherwise the watchdog timer will activate and reset the CPU.

If CPU processing comes to a standstill because of EMI or a
software bug, the program will signal to I/Oaddress + 443(hex) and
the timer will be interrupted. The timer will then automatically reset
the CPU and data processing will continue normally .

T o avoid an unexpected CPU reset you must write your program so
that it reads the I/O address + 443(hex) at an interval shorter than
the timer's preset interval. Programs can disable the W atchdog
Timer by reading the value preset in 443 (hex).

The watchdog timer must be programmed via direct I/O access
using the following procedure.

D.1.1 Watchdog timer enable, refresh and

disables procedures

exactly as stated or the watchdog timer will NOT
