Magic Touch Troubleshooting Guide
Controller: ProE-X & ProE	
Operating System: Windows 2000 & XP.

Problem Observed
1. Windows did not detect Magic Touch as a new hardware.

Suggested Causes and Solutions

1.1. The controller box is not connected to a free com port.
Check the connection.  Try a different com port, if available.

1.2. The Windows was not logged on correctly.
The driver must be installed with the administrator's password logon. 

1.3. The com port may be occupied by other device or defective.
Check in your Device Manager (Control Panel -> System) for conflicts 
(yellow exclamations). If conflict presents, try another serial port, 
or removing the other device.

1.4. The controller may be defective
If the red light on the controller is not on, or light is on, but it 
does not dim when the touch screen is touched, and this problem is 
consistent on both com ports, or on different computer, the controller 
may be defective. (Note: ProE's light stays off when drivers are not
correctly installed.  If light never blinks at Windows start-up, check
the port.  If port okay, then controller may be defective.) Contact 
tech support to report problem code: ProE2K01

Problem Observed
2. No response to the touch.

Suggested Causes and Solutions

2.1. Touch screen cable is not connected properly to the controller box.
Make sure the touch screen cable is connected to the controller box.  When 
the screen is touched, the light on the controller box should dim.

2.2. Installed the wrong driver.
Make sure the installation CD is labeled for Magic Touch.  If wrong driver 
has been installed, run uninstall to remove it. 

2.3. The driver is out of date.
Check the driver download page (at to compare 
the version listed with the one printed on your CD label.  If it is different, 
uninstall your driver.  Download and install the new one.

2.4. The driver was not installed correctly.
Make sure to follow the correct steps on user's manual.

2.5. Other touch screen driver may be installed previously.
Make sure all the previously installed touch screen drivers are removed before 
installing Magic Touch driver.

2.6. The touch screen panel may be defective.
The light on the controller box should dim when the screen is touched.  If the 
light on the controller box does not dim when touching the screen, it is either 
a bad connection or the touch screen is defective.  If the light dims without 
touching the screen, and it turns bright when the touch screen cable is disconnected 
from the controller box, the touch screen may be defective. Contact tech support 
to report problem code: ProE2K02

Problem Observed
3. The touch position is not accurate.

Suggested Causes and Solutions

3.1. The screen needs to be calibrated.
Make sure to use the stylus to touch the center of each circle, one at a time (total 4). 
For built-in touch screen kits (KTT series) and notebook models (KTMT-1214 & KTMT-1500), 
the cable connected to the touch screen may be reversed.  Unplug the cable and reverse 
the orientation and reconnect.  Run calibration again.

Problem Observed
4. The touch position is accurate in most areas, but off a lot in certain area.

Suggested Causes and Solutions

4.1. The touch screen may have linearity problem.
Open the paint program and use stylus to draw horizontal and vertical lines on the screen.  
If the line is curved in certain area, contact tech support to report problem code: ProE2K03

Problem Observed
5. The cursor keeps jumping to certain area, or is stuck there.

Suggested Causes and Solutions

5.1. When the cursor is stuck in certain area and the light on the controller dims, that 
indicates the touch screen may have shorts. At this point, the mouse cannot control cursor 
either.  Unplug the touch screen cable from the controller box, the red light turns bright 
and mouse can control the cursor again, that verifies the touch screen has shorts. 
Contact tech support to report problem code: ProE2K04.

Problem Observed
6. Touch screen does not work in certain program.

Suggested Causes and Solutions

6.1. The program may not be a Windows program, or not a mouse-driven program.
Touch screen is only compatible with Windows mouse-driven programs.  The typical application 
is for left mouse button clicking or dragging.

6.2. The icons or links may have a "mouse-over" effect, so the first touch sometimes cannot 
activate the icon or link.  Open Touch232 control panel, select "lift-off" mode and try again.
