FCC Class B
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interfer-
ence when the equipment is operated in a residential environment. This
equipment generates, uses and can radiate radio frequency energy. If not
installed and used in accordance with this user's manual, it may cause
harmful interference to radio communications. Note that even when this
equipment is installed and used in accordance with this user's manual,
there is still no guarantee that interference will not occur. If this equip-
ment is believed to be causing harmful interference to radio or television
reception, this can be determined by turning the equipment on and off. If
interference is occurring, the user is encouraged to try to correct the inter-
ference by one or more of the following measures:
• Reorient or relocate the receiving antenna
• Increase the separation between the equipment and the receiver
• Connect the equipment to a power outlet on a circuit different from that
to which the receiver is connected
• Consult the dealer or an experienced radio/TV technician for help
Warning! Any changes or modifications made to the
equipment which are not expressly approved by
the relevant standards authority could void your
authority to operate the equipment.

PPC-123 User’s Manual 2
Chapter 1 General Information
1.1 Introduction
The PPC-123 panel PC is a multimedia Pentium® III processor-based
computer that is designed to serve as a human machine interface (HMI)
and as a desktop computer. It is a PC-based system with 12" color TFT
LCD display, on-board PCI Ethernet controller, multi-COM port inter-
faces and a 16-bit stereo audio controller. With a built-in CD-ROM drive,
floppy drive and PCMCIA expansion sockets, the PPC-123 is as compact
and user-friendly as a notebook computer. Unlike notebook computers,
the PPC-123 is more durable and versatile in all applications. The panel
PC can be placed on a desktop to replace the traditional desktop com-
puter. In addition, its "fit anywhere" design makes it very flexible and
able to be used in many different kinds of installations. It can be wall
mounted, panel mounted or stood upright on a desktop.
For system integrators, this simple, complete, compact and highly inte-
grated multimedia system lets you easily build a panel PC into your appli-
cations. Common industrial applications include factory automation
systems, precision machinery, and production process control. It is also
suitable for many nonindustrial applications, including interactive kiosk
systems, entertainment management, and car park automation. Our panel
PC is a reliable, cost-effective solution to your application's processing
requirements.

1.2 How to use this manual
This manual contains all the information you need to set up and use the
panel PC. In addition to this manual, you may also want to consult the
manuals for your operating system, software applications and peripherals.
Whether you are a new or an experienced user, you will benefit more
from this manual if you are familiar with its organization. This manual is
divided into ten chapters, plus five appendices.
Chapter 1 (this chapter) outlines the organization of this User's Manual,
provides a complete specification description of the PPC-123, and sum-
marizes its main features.
Chapter 2 provides step-by-step instructions to help you set up and begin
using the panel PC as quickly as possible.
Chapter 3 provides important information about the daily use of the
panel PC, including using the CD-ROM drive, floppy drive and enjoying
the panel PC's audio capabilities.
Chapter 4 provides detailed step-by-step instructions to help you install
the internal key components, including the CPU, hard disk drive, memory
module, and so on.
Chapter 5 provides a detailed description of jumper settings and connec-
tors of the motherboard of the PPC-123.
Chapter 6 explains the VIA chipset.
Chapter 7 explains the PCI bus Ethernet setup.
Chapter 8 explains the VGA setup.
Chapter 9 explains the audio setup.
Chapter 10 explains the PCMCIA setup.
Chapter 11 explains how to configure and use the optional touchscreen.
Chapter 12 explains the Award BIOS setup
Appendix A details the LCD specifications used in the PPC-123.
Appendix B explains how to program the watchdog timer.
Appendix C includes various exploded diagrams of the PPC-123. These
diagrams will help system integrators disassemble the panel PC.

5 Chapter1
Appendix D includes all pin assignments on the connectors.
Appendix E helps users install the panel PC, which is mountable in a
variety of ways.
If you are a commercial user and the panel PC unit you bought is a com-
plete set with CPU, hard disk drive, SDRAM, CD-ROM drive, floppy
disk drive and PCMCIA expansion slots included, you may only need to
read Chapters 1 through 3 regarding hardware operation. For additional
drivers and BIOS setup information, you should read Chapters 6 through
12. (Chapter 11 is for users who want information about the optional
touchscreen.) If you want to upgrade your system, you may follow the
instructions in Chapters 4 and 5. If you are a system integrator who wants
to integrate the panel PC into your system, you can refer to appendices A
through E for information such as pin assignments and how to fully disas-
semble the panel PC.
