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.
