  • Find the serial port that is used internally, it's probably called USB Serial Port.

  • Connect the COM port to ID 1.

  • Click the Test COM x Monitor ID 1 button to verify it is working. 
  • In DISE CMS, in the settings for the screen communication, select Manufacturer: NEC Model: WMI, Control Input: Internal (not COM)
