4-16. Touch screen
The QT-7300 is equipped with a quick-response touch screen that enables keyboard-less operation. To use the
touch screen, a related application program needs to be installed. This chapter provides all of the information
to install and use the software of the Fujitsu touch screen systems for Windows98 SE and Windows 2000.
4-16-1. System Requirements
The Fujitsu touch screen system requires a serial interface. COM1 is assigned for the touch screen system in
the QT-7300 system.
4-16-2. Installation
This section describes the installation procedure for the Windows Driver Disk.
There are two steps to install the touch screen drivers into the QT-7300 system.
Step 1 : Driver installation
Step 2 : Calibration
4-16-2-1. Driver installation
The accompanying Windows Driver Disk contains the following software:
1) For Windows 98 SE
(1) Run the setup.exe (Touch Panel Windows 98 Driver disk) file.
(2) Select Primary install.
(3) Click OK button.
(4) Port setting window should open. Default condition is as below.
COM1, I/O address = 0x3f8, IRQ = 4
In the case that you want to use the touch panel as it is, click OK button.
(5) Restart the system.
Attention:
1) In the case that you need to use dual touch panels for a dual display condition, please select
Secondary install at step (2) when you install the second touch panel in addition.
2) In the case that you need to use dual touch panels for a dual display condition, please select
Primary and Secondary install at step (2) when you install the second touch panel at the same
time.
2) For Windows 2000
(1) Run the setup.exe (Touch Panel Windows 2000 Driver disk) file.
(2) Click OK button.
(3) Click OK button.
(4) Restart the system.

4-16-2-1. Calibration
1) For Windows 98 SE and Windows 2000
(1) Insert Floppy disk into Floppy Disk Drive (A:).
(2) Open Explorer .
(3) Click Floppy Disk Drive (A:) in All Folders
(4) Double Click CALWIN(CALWIN.EXE) then execute.
(5) Calibration Program. (Nine + marks will be shown on the display)
(6) Hit + marks (touch on the touch panel).
Color of + mark will be turned Black or Red by each touch, if touch is recognized.
(7) After touch all nine + marks, hit Enter key.
(8) Hit Enter key after + marks disappeared to finish.
Note at calibration :
1) You will be prompted to touch nine calibration points on the screen. Before you touch, position
yourself in front of the screen in 90-degree vertical angle against the screen.
2) Use sharp soft object (i.e. pen shaped plastic object) instead of your finger for accurate positioning.
3) Please do not use any hard sharp objects (i.e. knife, metal ballpoint pen), it may cause damage
on the touch screen panel.
4) Calibration data will be stored in the EEPROM on the touch screen controller board. You will not
need to calibrate at each system start by power on as long as data is stored in the EEPROM.
Why Calibration is Necessary?
The necessity for calibration is unique to the touch screen. Unlike mouse or keyboard applications where the
cursor is part of the image, a touch screen is a physical overlay with an independent coordinate system. Only
by knowing the position of the image can the PC software convert touch screen coordinates into image
coordinates.
Besides the differences among touch screens and controllers, calibration also compensates for the variation in
video image among displays. The image is affected by horizontal and vertical adjustments on the monitor and
by the physical mounting of the touch screen.
Additional calibration complications include image blooming, where bright-colored images expand, and the pin
cushion effect, which causes the corners of the display to be stretched. Poor display linearity can cause similarly
sized boxes to be larger at the edges of the screen than they are in the middle, or vice-versa. The displayed image
can also be tilted. Even changing video modes can affect the screen size.
Perfect calibration cannot be achieved in all circumstances. For example, the user can encounter parallax
problems with a change in position, or because the present user is not the same stature as the person who
calibrated the screen.
When Re-calibration is Necessary?
Once calibrated, the touch screen will be ready to run automatically each time the system is restarted. Re-
calibration should only be necessary after moving or resizing the video image, or after changing either the touch
screen, controller, or monitor.
Refer calibration procedure based on your O/S system and re-calibrate if necessary.

2. Access the System Properties window
¥ Double -click on System icon and then choose Device Manager from the menu.
¥ A new window will pop-up with Other Device represented by a ? mark. Click this ? mark and one
device marked with ? appears on its subset device list. One device specifies the PCI Ethernet
Controller.
3. Enter the PCI Ethernet Controller Properties window
¥ Move the cursor to the PCI Ethernet Controller then double-click your left mouse button. The screen
then display the PCI Ethernet Controller Properties window.
4. Detect and specify the .INF network device driver path
¥ Click on Driver from the menu bar and a new screen appears with the Update Driver... button.
¥ Click on the this Update Driver... button and the Update Device Driver Wizard window appears.
Choose Display a list of all drivers...  then click on the Next> button to proceed.
¥ Insert the EtherNet RTL8139 Disk II diskette (Disk ) into Drive A: and clock on Have Disk.
5. Capping the installation

¥ The Update Wizard display the message that it has found the driver. Click on Next> .
¥ Click on the Finish button to complete the installation of the PCI Ethernet Controller.
6. Provide Network Information
¥ Right after completing the network adapter installation, the system displays the network window
requiring you to fill up your computers name, the workgroup it will appear in, and a short description
of it. Refer to the following screen.
¥ After filling up the items, press the Close button to exit.
7. Reboot the system
¥ Your system will now ask you whether youd like to reset the computer. Click on the Yes button.
