3. Connect the male end of the power cord to an electrical outlet.
4. Connect the USB CD-ROM drive.
5. Connect the female end of the power adapter cord to the AC inlet located
at the rear side of the QPC-DC Series.
2.2.2 System BIOS Setup
If you are a commercial user, the QPC-DC SERIES should have been set up and
configured by your distributor already. In the case where you may find it necessary to
change some system configuration information, you will need to run the Basic Input
Output System (BIOS) setup program. Under the following conditions, the CMOS
settings may be changed:
1. The system is starting and being configured for the first time with new
components.
2. The hardware devices attached to the QPC-DC SERIES system have
been changed.
3. The CMOS memory has lost power and the configuration information has
been erased.
The BIOS setup program is stored in ROM, which can be accessed by pressing
<DEL> key on the keyboard immediately when the system is powered on. In order to

QPC-DC Series USER MANUAL 2-13
retain the specified setup information when the system power is turned off, the
system setup information is stored in a battery-backed CMOS RAM. The battery is to
ensure the settings will not be erased when the computer is turned off or reset. When
the computer is powered on again, the system will read the settings stored in the
CMOS RAM and compare them to the equipment check conducted during the power
on self-test (POST). If any error or mismatch occurs, an error message will be shown
on the screen and the computer will be prompted to run the setup program.
2.2.3 Operating System and Driver
The standard QPC-DC Series system may not be equipped with an operating
system (OS). If you are a commercial user, the system is likely to have been
pre-installed with a proper operating system and software drivers by your dealer or
system integrator. If the system is not pre-installed with any system OS and drivers
or you intend to install your preferred ones, you will need to load an OS and software
into the system.
1. Use the External USB CD-ROM/DVD-ROM Drive to load an OS from a
bootable CD. Recent releases of operating systems include setup programs
that load automatically and guide you through the installation. You can also
refer to your OS user manual for instructions on formatting or partitioning the
hard disk drive before any software installation.
2. Install software drivers for your operating system and any peripherals that are
connected. The QPC-DC Series Utility CD includes software drivers for
Chipset,Audio, LAN, Touch screen, VGA Display, Camera, 3GS Module and
Wireless drivers. See driver installation chapters for more information.

QPC-DC Series USER MANUAL 3-15
Chapter 3 TOUCH SCREEN
3.1 Introduction
The QPC-DC Series are installed with a 5-wire analog resistive touch screen. The
touch screen panel turns the flat-panel display into a dynamic graphical user interface
(GUI) and data entry device. The touch screen represents a replacement to needing a
keyboard and mouse to interface with the computer. People associate actions or
functions with visual images better than a combination of keystrokes or button clicks.
Using a touch panel is more entertaining for the operator and actually requires less
brain activity than traditional control devices.
The built-in touch screen system has three main components: a clear solid glass
screen formed to match the shape of a display, a sophisticated electronic controller,
and a software driver.

3.3 Touch Screen Software Driver
Touch screens configured with the QPC-DC Series will require software drivers to be
installed to enable the touch screen functionality. The driver software scales the
absolute coordinates received from the touch screen controller into translated screen
coordinates, using the calibration points obtained with the Video Alignment program
included with the driver software. The driver also performs other operations as

QPC-DC Series USER MANUAL 3-16
directed by the application.
3.4 Touch Screen Care and Clean
Only use soft non-abrasive lint free wipes with Isopropyl 99% to clean dirt or stains
found on the touch panel. Always dampen the wipes and then clean the touch panel.
Chemical liquids with strong acidic base will damage the touch screen and void the
warranty.
3.5 Troubleshooting
If you experience operational difficulties with the touch screen system either during or
after installation, the following sections will help you to determine the source of
problems.
The first step in troubleshooting is to determine whether the problem is related to the
display, software, or hardware.And please pay attention to special notes as follows.
•Do not confuse display problems with touch screen problems, as the two
issues are unrelated.
•Software problems are determined by a basic hardware functionality test. If the
hardware transmits touch coordinates correctly, then the problem is probably
with the driver or application software.
•Hardware problems may be caused by the touch screen, controller, cabling,
power supply, or the integration of the touch screen components in the display.
3.5.1 Display Problems
If the display has some problems (such as no video, no horizontal or vertical
synchronization, raster non-linearity, etc.), remember that the video function of the
display and the touch screen installed on the display are separated systems.
Therefore, problems with the display should be treated as display problems, not
touch screen problems. Diagnostic procedures and any possible corrections for
display problems should be performed.
3.5.2 Video Alignment Problems
If the touch screen is responding and the data is linear, but it does not respond at the
appropriate zone, try to align the video. Use Touchkit program.
3.5.3 Software Troubleshooting
Before beginning software troubleshooting, verify that the touch screen hardware is
working normal for serial controllers by running the touchscreen program. If the

QPC-DC Series USER MANUAL 3-17
touch screen is operating, then the problem may be with the driver software, the
application software, or a conflict with other hardware or software. (The problem may
also be due to incorrect Video Alignment of touch screen).
3.5.4 Hardware Troubleshooting
The touch screen system hardware troubleshooting may require analysis of the
touch screen, controller, cables, power supply, and the integration process. To start
with the controller would be the best. Use the controller power-on diagnostics that
are displayed when the touch panel utility driver software is loaded to check for
specific faults. Also check whether the controller is transmitting any touch data.
No touch data:
When no touch data is reported, the problem may be the touch screen, controller, or
cabling. If the features of controller power-on or LED do not identify the problem, you
can use individual system components what are available to be instead.
Intermittent touch data:
If the system is reporting touch data at a slow or varying rate, the problem may be
caused by a low signal strength or excessive noise in the system. And when the
touch screen is not touched but it shows the touch data often caused by excessive
system noise.
