Troubleshooting Tips and Tools
If you are experiencing problems with the touchscreen, check that all
cables are connected properly and restart your system.
For cursor adjustments, use the MicroTouch Touchscreen Control
program or Microcal to calibrate the touchscreen. For more
information on the MicroTouch Touchscreen Control program, refer to
the Chapter 2. For more information on Microcal, refer to Chapter 4.
Use Microcal to locate the touchscreen controller and test the
touchscreen.
If your touchscreen or mouse is not working, the communication
settings are probably incorrect. If both devices are trying to use the
same communication port, a device conflict will result.
Modifying the Communication Settings
You usually do not need to change the communication settings. You
may want to change them, for example if you move the touchscreen
controller and touchscreen to a different COM port, or if you add a
TouchPen controller to the system and you want to adjust the COM
port’s baud rate to communicate with the controller.
To correct the communication settings:
1. Run Microcal.
2. Note the COM port, COM IRQ, and baud rate settings used by the
touchscreen controller. The Microcal Status box displays this
information.
3. Open the Touchscreen Control program and specify the same
communication settings in the Hardware Controls dialog box. The
settings in the Hardware Controls dialog box must match those
used by the touchscreen controller.
If you are using Custom communication settings, also be sure that
the port address is correct.
4. Reboot the system.
