1. Check the terminal port
First, check whether the wiring interface is loose, and then check whether there is a conflict between the serial port and the interrupt number, if there is a conflict, the resources should be adjusted to avoid the conflict. Then check whether there are cracks on the surface of the industrial touch screen, and replace them in time if there are cracks. It is also necessary to check the surface of the touchscreen for dirt and, if so, remove it with a soft cloth. Observe and check whether the indicator light on the control box is working properly, and when it is normal, the indicator light is green and flashing.
2. Comprehensive inspection of the substitution method
If the above parts are normal, you can use the replacement method to check the industrial touch screen, first replace the control box, then replace the touch screen, and finally replace the host.
(1) It may be that one of the cables connected to the host keyboard KO (take the 5 volt touch screen working voltage from the keyboard KO) is not connected in the connection of the industrial touch screen, please check the connection.
(2) It may be that the serial slogan selected during the driver installation process of the industrial touch screen does not correspond to the serial slogan actually connected to the touch screen, please uninstall the driver and reinstall it.
(3) It may be that the host is a domestic original machine, and the operating system installed is the OEM version, which has been adjusted by the manufacturer, resulting in the non-standard nature of serial port communication, which is not compatible with the touch screen driver, if feasible, please format the hard disk, and drive the touch screen after installing the system.
(4) It is possible that the industrial touch screen driver version is too low, please install the latest driver.
(5) Check and adjust whether there is a conflict between the device and the serial port resource in the host. For example, if the default IRQ of some NICs is 3 and conflicts with the IRQ of COM2, you should change the IRQ of the NIC to an idle and unused IRQ.
