Last time I "used" NT4 it was to set up a machine for a specific piece of software so I could test a SICK 2D LIDAR unit (one of the blue "coffee pot" units) I had purchased off Ebay; sometime around 2014/15 IIRC. Initially turned out that it had been set to RS485 mode, and I didn't have an adapter, and I didn't even know if it worked if I was able to get it into that mode. So with the help of a sympathetic engineer at SICK, he had me send to unit to them and he reset it (to RS232) and tested it. When I got it back, I tested it with the machine again and it worked perfectly. He didn't charge me anything for the service. You don't see that kind of support anymore - almost no company will say "yeah, sure, send us a unit you bought second-hand off Ebay to us and we'll take a look at it, fix it, etc - and no charge to you, either - even though you're just a hobbyist and have no support contract" - it shocked me.
