Why does the touch fail to function after installing the PenMount Windows Universal Driver?
1. Uninstall the driver, making sure that the PenMount control board is connected to the computer, then restart Windows.
2. Make sure that the driver matches the PenMount control board and operating system you are using. If the PenMount device uses a RS-232 interface and works in Non-PNP mode, please make sure that the RS-232 cable is connected to the computer first.
3. Check to see if there is an unknown device or HID-compliant mouse in the [Mice and other pointing devices] group of the [Device Manager].
4. If no device is found in step (3), please check to see if the connector on the PenMount control board is loose, and whether the COM / USB port is working correctly.
5. Re-install the PenMount Windows Universal Driver.
If touch function still fails to initiate after performing the previous checks, please contact us.
