The 8-wire touch cable (eight wires) is used to connect the 5-wire resistive touch screen, which has a connector on its flat, with the 5-wire USB or RS232 controller board.
Please note that this cable is designed for the connection between the penmount controller board and the touchscreen of the AMTouch brand, and it may not work on other brands. Of course, even in this case, with a little skill and change in the wiring, the problem will probably be solved.
If you encounter problems after installing the driver, during the calibration of the touch screen board, it is possible that the wiring arrangement of this cable is different from your product and needs to be changed.
