NEC OPS can communicate with the screen directly, without the need for a serial or ethernet cable.
First please install ”NEC_NA2 - RS232 WMI Provider” from https://www.dropbox.com/s/4w6skgf3fhpejsg/NEC_NA2%20-%20RS232%20WMI%20Provider.zip?dl=0
and follow the below instructions:
- 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)
Change the settings in the screen so that OPTION POWER is "OFF" This way the PC itself is not shutdown when the screen is.
