Frequently Asked Questions

Hi, My 7270 latitude touch screen stopped working shortly after first use (after win update worked again but for a short time). All drivers are up to date. In device manager a USB device shows as unknown (yellow warning triangle), otherwise there are no indications to the source of the problem. I have tried what you said but couldn't find the touch screen controller. I will revert to window 7. Help me with the link to download HID complaint touch screen driver for window 7. I will appreciate that. The touchscreen device is labeled HID-compliant touch screen, or similar. Right-click the touchscreen device. If the option to enable the device is included in the menu, click Enable. Reinstall the original touchscreen device driver that came installed on your computer using the following steps: In Windows, search for and open Device Manager.

The message will appear informing you to connect your touch monitor or touch controller to USB/RS232 serial port on your PC. Please make sure that all connectors are securely fastened to your touch screen and PC, then press OK to continue....

If you wish to enable Multi-Monitor System Support utility, then select the box below however the installation of this utility is not covered by this tutorial. Click on Next to continue....

During installation the TouchKit software will automatically search all available COM ports for Touch Screen Controllers. If touch screen controller has been detected on any COM port, it will be automatically registered with the TouchKit software. If the software does not find a touch screen controller, the most likely cause is that the serial cable is not connected to your PC. After all COM ports have been searched for Touch Screen Controllers and TouchKit drivers are installed, the following screen belowwill be displayed.

Drivers Touch Screen Controller

To begin the calibration process...

Either select Windows Start Menu/TouchKit/Configure Utility as shown below.

or click on the TouchKit icon on your desktop

This will activate the TouchKit calibration software and the screen shown below will be displayed..

Switch to the Tools tab and click on the 4 Points Calibration button shown below.

The calibration screen will appear on your monitor as below..

Starting at the bottom left hand side of the screen, the calibration software will place a number of flashing red crosses on the screen. Touch the flashing crosses with your finger as they appear, keep your finger on the screen until the cross stops flashing ( do not use a mouse to select the crosses ). The cross will then turn green to confirm your finger touch has been registered. Repeat this process for bottom right, top right and top left crosses. When the calibration process is complete, calibration data will be saved to the hard disc and the software will return to the TouchKit/Tools tab shown below. Press OK to continue.

The first step in troubleshooting a touchscreen system is to determine whether the problem is related to the display, software, or hardware:

  • Do not confuse display problems with touchscreen problems — the two are unrelated.

  • Software problems are determined by a basic hardware functionality test. If the hardware transmits touch coordinates correctly, then the problem is with the driver or TouchKit software.

  • Hardware problems may be caused by the touchscreen, controller, cabling, power supply, or by the integration of the touchscreen components in the display.

  • The easiest way to verify a hardware failure is by substitution, if you have more than one unit to try.

Connections.

Ensure that all connectors are securely fastened to your touch screen and PC (refer to Answer 1.01 above).

Select Start Menu/TouchKit/Configure Utility to bring up the TouchKit interface. Ensure the General tab is selected and that a touch screen controller is listed in the Installed Touchscreen Controllers list. If no controller is present, select Add to search for your touch controller. When a controller is found, ensure the number of the COM port listed matches the COM port you have connected the touch screen controller to. If no controller can be found, check cable connections.

Ensure the Hardware tab is selected and that a touch screen controller is listed in the Controller Model. Do not worry if the entries in the Controller Model and Firmware Version are not the same as yours as this can vary depending on the model purchased.

TouchKit Software.

To successfully install the TouchKit drivers on a Windows 2000, XP or Vista machine, please ensure your are logged on as the ADMINISTRATOR or have administrator privileges with your current login.
Ensure that you did not select the PS/2 interface driver box when installing the TouchKit software.It may be necessary to un-install the software and re-install to ensure this box has not been ticked.

Touch Sensitive Side.

If the TouchKit software crashes when running 4 Points Calibration utility and no touch locations are detected, please ensure you're touching the touch sensitive side of the touch panel. The touch sensitive side is the side with the thin ITO Film layer. It is also marked with Touch Side label.

Calibration Errors.

If the touch screen works but is inaccurate, the touch screen requires calibration. Select Start Menu/TouchKit/Configure Utility to bring up the TouchKit interface. Ensure the Tools tab is selected. Select 4 Points Calibration as shown below. Touch the calibration targets in turn as instructed (refer to Answer 1.03 above). Do not rest your hand on the touch screen when touching the calibration targets. Do not touch the screen while the TouchKit software saves the calibration data.

For superfine calibration switch to Settings tab and select the 25 Points option shown below, then click Apply..

Now switch to Tools tab and click the Linearization button shown below....

The software will present a 25 target screen for more consistent accuracy across the whole area of the touch screen as below. Touch each target in turn as directed. Do not rest your hand on the touch screen when touching the calibration targets. Do not touch the screen while the TouchKit software saves the calibration data.

If all fails !
Try connecting to another PC ! If the touch screen still fails to work, try connecting it to a different PC with a basic set-up and a different O/S.

Touchscreen Problems.

1. No response to the touch.

  • Make sure the touch screen cable is properly connected to the controller (refer to Answer 1.01 above). Under normal conditions, the LED indicator light is off. When the finger touches the touch screen, the LED indicator light is on and remains in this state until the finger leaves the touch screen; the controller is operating properly.

  • Make sure the correct TouchKit driver and software for your specific O/S is installed. Check your supporting CD or the TouchScreen Controller Downloads Page for the correct TouchKit driver and software. If wrong driver has been installed, run uninstall to remove it and then install the correct driver.

  • Make sure the COM port and the controller are working properly. If testing failed (controller error), try it on a different COM port or computer, if available. If the controller is defective, contact tech support to report problem with the controller.

  • Make sure the touch screen is functional. The LED indicator on the controller lights when the screen is touched and remains in this state until the finger leaves the touch screen. If the light on the controller does not respond to the touch or the LED indicator on the controller is always on, the touch screen might be defective. If you’re unable to measure a resistance across the X-axis and Y-axis, the touch screen is most likely damaged, consider replacing your touch screen.

2. The touch position is not accurate.

  • Make sure that the protective plastic films are removed from the both sides of the touch screen.

Home Automation Touch Screen Controller

  • The touch screen needs to be calibrated (refer to Answer 1.03 above).

On Screen Controller

3. The touch position is accurate in most areas, but off a lot in certain area(s).

  • The touch screen may have linearity problem. Open the TouchKit software, switch to Tools tab and click the Linearization button (refer to Answer 1.05 Calibration Errors above). When finished, run Draw Test to check the touch accuracy.

  • The touchscreen system may have an offset in certain area(s). There is a common problem with the newer TouchKit driver versions on several Windows 2000 and Windows XP systems. The older TouchKit Driver v4.3.0.2412 seems to fix the offset.

4. The cursor keeps jumping ('jumpy pointer') to certain area(s) or is stuck there.

  • The touch screen needs to be calibrated (refer to Answer 1.03 above).

  • The controller can be defective (fried chip, etc.). Try testing with a different controller, if available. If the controller is defective, contact tech support to report problem with the controller.

  • The touch screen may have shorts or open wires. If the light on the controller does not respond to the touch or the LED indicator on the controller is always on, the touch screen might be defective. If you’re unable to measure a resistance across the X-axis and Y-axis, the touch screen is most likely damaged, consider replacing your touch screen.
