Found the recommended EC500 driver and EVEM V2 manual from the manufacturers site
https://www.nvcnc.net. I'm exited to see if this thing will be good enough in the end to replace my two parallel ports and two BOBs which limited the speeds of my servos.
So far Mach3 has accepted the driver and responds to Emergency input and Digitize inputs from EVEM inputs which I'm able to test on my drawing board with a Dell laptop. When starting I saw plenty of LAN traffic between PC and NVEM but no communication between Mach3 and EVEM and nothing worked. After completely disabling Firewall (for both Private and Public networks) communication started to work.
I have the NVEM V2s IP at 192.168.1.11 which is in the same IP address space my router uses so I wonder how that can work if the WIFI is enabled at the same time? (Can't test that as my Dell laptop automatically disables WIFI if LAN cable is plugged in.) Would like to hear about that if someone has the knowledge. Next step is to get things working on an old Win10 32bit PC for Mach3 and also get a new iHSV86 servo motor to run with EVEM.
