NMEA is nothing more than a RS-422 connection, something that is used

screw up big time...


Not at all. No RS-422 connection is made with screw terminal from little
bare wires sticking out of a plastic plug, plugged into a plastic box.

Oh? When I look for RS422 converters on Google, several boxes turn up that
all have screw terminals for the RS422/485 connection.

Look at Moxa, a brand that is used a lot in industrial applications:

Plastic box, screw terminals.

There have never been any screw terminals on any of my computers....er,
ah,
well, since the first one back in the early 70's...(c;

I think you'll find more RS-422 devices with screw terminals than with
connectors. Talk to a professional installer why this is.
