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

I give up. The problem here is RF interference with very close by HF radio
equipment used on BOATS. No amount of excuses is going to change the fact
that the damned screw terminals, unshielded wiring (even balanced, which
it's not) and open cabling hooked to the big boat DC antenna is going to
change it.

NMEA should have used a SEALED, WATERPROOF, SHIELDED connector, STANDARD to
all devices from all manufacturers to eliminate RF interference. They
should have mandated the inside of the cheap plastic boxes be painted with
shielding paint and displays be covered with shielding plastic to stop the
radiation from there. They didn't. Everyone "did their own thing", like
you did. The customers pay for it with all this non-standardized ****ware
screwed together with the corroded wiring and rotting terminal strips open
to the sea air.

Stupid...really stupid.
