No Touch Response
If you are experiencing problems with the touch screen, check that all cables are connected properly and restart your system.
If the controller information box on the MT 7 Control Panel Main tab is grayed out and contains no information, MT 7 software is not communicating with the touch screen.
If you are using a serial port, verify that any previously loaded hardware/software that used the same serial port as your touch screen has been uninstalled. Even though the previous hardware is disconnected, the software may still be claiming the port. Ensure that all components are completely removed from the System files.
Check the following items:
- Make sure the touch screen controller is connected to a serial port.
- Review the installation procedures and verify all hardware is properly connected. Check the serial port and touch screen cable connections. Check that the touch screen and controller cables do not have any kinks and that connector pins are not bent.
- Reset the touch screen and its controller. Turn off both the computer and the monitor, wait a few minutes, and then turn on each device again.
