Touch Panel Not Responding

A common scenario for touch panels not to respond is when the X20 has been updated. Whenever you update an X20, the settings under Server\Frame configuration reset. If the External Control device is connected to the X20 via RS232, this setting is reset to None. Determine which serial port is being used on the back of the X20 and set it in the software.

Go to Server\Frame configuration. In the property panel, go to the External Control menu and assigned Serial port to match COM port being used then click Apply Setting Now at the top of the property panel and your system will do a soft reboot.
