Industrial touch screen screen screen and resistance capacitance in the troubleshooting methods are introduced. Industrial touch screen is the application of human-computer interaction in the industrial equipment, industrial all-in-one type has a lot of, among them, the more common is the capacitance screen and resistive screen, and the different screen after a failure, maintenance methods are different, the resistance of the capacitive touch screen troubleshooting way what the difference? We will follow up to below table ear we together and see it. A, capacitive touch screen repair: 1, if it is built-in card, check the jumper is whether to jump to control card. 2, to check whether the touch screen attachment is, if it is an external box control card, the control box part, through the back shape tank, straight out and touch screen cable connection. Take the power part through a keyboard conversion head ( Must first connect the RS232 port head next to the small rubber head to pull, can to the power supply line) , where a host to the keyboard, the other end connected to computer keyboard. Will pick up to 5 v power supply of a small head, insert the joint of 232 will be RS232 connection head out control box, inserted into the host 9 pinhole.

May be the computer motherboard and touch screen control box is not compatible, please replace the host or the motherboard. Industrial touch screen screen screen and resistance capacitance in the troubleshooting methods are introduced.
