Chapter 5 Troubleshooting the Touchscreen 121
Problem: Cursor does not move.
Could be one of the following problems:
The touchscreen controller is not connected to the COM port.
Check the controller connection.
The communication settings being used by the touchscreen driver
to communicate with the touchscreen controller do not match the
communication settings used by the touchscreen controller.
Use Microcal to determine the touchscreen controller settings.
Use the Hardware Controls dialog box in the Touchscreen Control
program to modify the communication settings used by the
touchscreen driver so that they match those of the controller.
For more information on Microcal, refer to Chapter 4. For more
information on the Touchscreen Control program, refer to
Chapter 2.
Another device is using the same COM port, IRQ, or base address
as the touchscreen controller. Use Microcal to specify unique
communication settings for the touchscreen controller. Use the
Hardware Controls dialog box in the Touchscreen Control
program to modify the communication settings used by the
touchscreen driver so that they match those of the controller.
Reboot the system.
For more information on Microcal, refer to Chapter 4. For more
information on the Touchscreen Control program, refer to
Chapter 2.
Problem: Touchscreen does not acknowledge touches.
Could be one of the following problems:
You are using an SMT2 controller (which has AutoBaud enabled)
and you turned off power to the touchscreen controller, for
example you turned off the monitor. Reinitialize the controller
using the Re-initialize button in the Touchscreen Control
program’s Hardware Controls dialog box.
For more information on the Touchscreen Control program, refer
to Chapter 2.
