General Information  
This chapter gives background informa-  
tion on the PCM-5820 Series.  
Sections include:  
• Board specifications  
• Board layout and dimensions  
Download from Www.Somanuals.com. All Manuals Search And Download.  
1.1 Introduction  
The PCM-5820 Series is the ultimate cost-effective solution for  
limited space applications. It offers all the functions of an  
AT-compatible industrial computer on a single board and only  
occupies the space of a 3½" hard drive. The PCM-5820/5820L  
comes with an embedded high-performance GXM-233 processor  
on-board. The PCM-5820E and PCM-5822 come with a low  
power GXM-200 processor on-board. For maximum performance,  
the PCM-5820 Series also support an SDRAM SODIMM socket  
that can accept up to 128 MB memory.  
On-board features include an Ethernet interface, audio interface,  
socket for Compact Flash Card, Enhanced IDE interface with up to  
Ultra DMA 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. An SVGA/LCD  
display controller (LCD, and CRT displays) allows LCD screen  
resolutions up to 1024 x 768 and CRT resolutions up to 1280 x  
1024 @ 16 colors. Supports LVDS interface (PCM-5820L and  
PCM-5820E only) for long distance LCD panel signal transmis-  
sion and EMI protection add-ons. Also provided is a TV-out  
function (PCM-5822 only) for NTSC and PAL TV format that  
supports composite, S-video and SCART (optional) outputs.  
The PCM-5820 Series 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-5820 Series has a  
PC/104 connector for future upgrades.

2.4 Setting jumpers  
2.4.1 Introduction  
You may configure your card to match the needs of your applica-  
tion 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.

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 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  
static-dissipative surface or in a static-shielded  
bag when they are not in the chassis.

2.6 Installing DRAM (SODIMMs)  
2.6.1 Introduction  
You can install anywhere from 16 MB to 128 MB of on-board  
DRAM memory using 16, 32, 64 or 128 MB 144-pin SODIMMs  
(Small Outline Dual In-line Memory Modules).  
2.6.2 Installing SODIMMs  
Note:  
The modules can only fit into a socket one way  
and their gold pins must point down into the  
SODIMM socket.  
The procedure for installing SODIMMs appears below. Please  
follow these steps carefully.  
1. Ensure that all power supplies to the system are switched Off.  
2. Install the SODIMM card. Install the SODIMM so that its gold  
pins point down into the SODIMM socket.  
3. Slip the SODIMM into the socket at a 45 degree angle and  
carefully fit the bottom of the card against the connectors.  
4. Gently push the SODIMM into a perpendicular position until  
the clips on the ends of the SODIMM sockets snap into place.  
5. Check to ensure that the SODIMM is correctly seated and all  
connector contacts touch. The SODIMM should not move  
around in its socket.

2.7 IDE hard drive connector (CN11)  
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, PIO mode 3, mode 4,  
and Ultra DMA 33 mode.  
2.7.1 Connecting the hard drive  
Connecting drives is done in a daisy-chain fashion and requires  
one or two cables, depending on the drive size. All required cables  
are included in your PCM-5820 Series package. 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. However, the  
required connectors are not included in the PCM-5820 Series  
package.  
Wire number 1 on the cable is red or blue, and the other wires are  
gray.  
1. Connect one end of the cable to CN11. 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.

2.8 CompactFlash™ disk (CN19)  
The PCM-5820 Series is equipped with a CompactFlash disk  
socket on the solder side and it supports the IDE interface Com-  
pactFlash disk card. The socket itself is especially designed to  
prevent any incorrect installation of the CompactFlash disk card.  
When installing or removing the CompactFlash disk card, please  
make sure that the system power is off.  
The CompactFlash disk card is defaulted as the E: disk drive in  
your PC system.  
2.9 Floppy drive connector (CN2)  
You can attach up to two floppy drives to the the PCM-5820  
Series' on-board controller. Any combination of 5¼” (360 KB and  
1.2 MB) and/or 3½” (720 KB, 1.44 MB, and 2.88 MB) drives is  
possible.  
A 34-pin daisy-chain drive connector cable is required for a dual-  
drive system. A 34-pin flat-cable connector is fitted on one end of  
the cable while the other end sports two sets of floppy disk drive  
connectors. Each set consists of a 34-pin flat-cable connector (for  
the 3½” drives) and a printed-circuit board connector (for the 5¼”  
drives).  
2.9.1 Connecting the floppy drive  
1. Plug in the 34-pin flat-cable connector into CN2. Make sure  
that the red wire corresponds to pin 1 on the connector.  
2. Attach the appropriate conector at the other end of the cable to  
the floppy drive(s). You can use only one connector in the set.  
The set at the other 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.  
20  
PCM-5820 Series User's Manual  
Download from Www.Somanuals.com. All Manuals Search And Download.  
When connecting a 3½” floppy drive, you may have some  
difficulties in determining which pin is pin number one. Look for a  
number on the circuit board indicating pin number one. In addi-  
tion, you should check if the connector on the floppy drive has an  
extra slot. If the slot is up, pin number one should be on the right.  
Please refer to any documentation that came with the drive for  
more information.  
If needed, connect the B: drive to the connectors in the middle of  
the cable as described as above.  
If your cable needs to be custom made, you can find the pin  
assignments for the board's connector in Appendix A.  
2.10 Parallel port connector (CN3)  
Normally, the parallel port is used to connect the card to a printer.  
The PCM-5820 Series includes a multi-mode (ECP/EPP/SPP)  
parallel port, accessed through CN3 - a 26-pin flat-cable connec-  
tor.  
You will need an adapter cable if you use a traditional DB-25  
connector. The adpater cable should have a 26-pin connector on  
one end and a 25-DB connector on the other.  
The parallel port is designated as LPT1 and can be disabled or  
changed to LPT2 or LPT3 in the system BIOS setup.  
The parallel port interrupt channel is designated as IRQ7.  
The proper ECP/EPP DMA channel can be selected via the BIOS  
setup.

The PCM-5820 Series 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. If the keyboard is not present, the standard  
PC/AT BIOS will report an error or failure during the power-on  
self test (POST) after resetting the PC. The PCM-5820 Series  
board's BIOS standard setup menu allows you to select "All, But  
Keyboard" under the "Halt On" selection. This allows non-  
keyboard operation in embedded system applications without the  
system halting during the POST.  
2.12 Power connectors  
2.12.1 Main power connector +5 V, +12 V (CN9)  
Supplies main power to the PCM-5820 Series (+5 V) and devices

adapter cable is needed if traditional telephone jack connectors are  
used for these audio signals.  
2.14.2 CD audio input connector (CN1)  
All CD-ROM drives can provide analog audio signal output when  
used as a music CD player. The CN1 is a connector to input CD  
audio signals into the audio controller. The audio cable of your  
CD-ROM drive is suitable for connection to CN1.  
2.14.3 Audio power source setting (J1)  
The PCM-5820 Series is designed to work with a single +5 V  
power supply as audio interfaces usually function under +5 V.  
However, most audio controllers require an independant +12 V  
power source since this avoids noise interference from other  
digital circuits. By using J1, the PCM-5820 Series' audio interface  
can also accept +12 V power sources for improved audio quality.

CN18 is a 15-pin, D-SUB connector commonly used for conven-  
tional CRT displays.  
Detailed information on pin assignments for CRT display connec-  
tor CN18 is given in Appendix A.  
2.16.2 Flat panel display connector (CN12)  
CN12 consists of a 44-pin, dual-in-line header.  
The power supply (+12 V) for CN12 is dependant on the supply  
connected to the board. Therefore make sure that CN9 is connect-  
ed to a +12 V power supply.  
The PCM-5820 Series provides a bias control signal on CN12  
which can be used to control the LCD bias voltage. It is recom-  
mended that the LCD bias voltage not be applied to the panel until  
the logic supply voltage (+5 V or +3.3 V) and panel video signals  
are stable. Under normal operation the control signal (ENAVEE)  
is active high. When the PCM-5820 Series board's power is  
applied, the control signal is low until just after the relevant flat  
panel signals are present.

4.1 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.  
4.1.1 System configuration verification  
These routines check the current system configuration against the  
values stored in the board’s CMOS memory. If they do not 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 informa-  
tion has been erased.  
The PCM-5820 Series' 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.

Installing PC/104  
Modules  
This appendix gives instructions for  
installing PC/104 modules.  
Download from Www.Somanuals.com. All Manuals Search And Download.  
D.1 Installing PC/104 modules  
The PCM-5820 Series' PC/104 connectors give you the flexibility  
to attach PC/104 modules.  
Installing these modules on the PCM-5820 Series is quick and simple.  
The following steps show how to mount the PC/104 modules:  
1. Remove the PCM-5820 Series 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. (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 screws.

Programming the  
Watchdog Timer  
The PCM-5820 Series 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.

E.1 Programming the watchdog timer  
Jumper J3 controls the watchdog settings. The default configura-  
tion of the timer is enabled via a system reset.  
To enable the watchdog timer, you must write a program which  
writes 1 to 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 write 1 to 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 IRQ11. When you  
want to disable the watchdog timer, your program should write 0  
to I/O port 443.  
If CPU processing comes to a standstill because of EMI or a  
software bug, your program's signals to I/O port 443 to the timer  
will be interrupted. The timer will then automatically reset the  
CPU or invoke an IRQ, and data processing will continue normal-  
ly.  
You must write your program so that it writes 1 to I/O port 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.
