How do we hook them up WITHOUT using the multiplexer you are selling?

How do you isolate the balanced output from ground in the bottom
diagram, without providing a galvanic path to the other instruments?

Of course the crap instrument on the right provides its own ground
path for everything hooked to A+, anyway, along with a great path for
the SSB RF to tear into no matter what shielding you use.

Is there a path in your multiplexer from A+ to GND to develop this
signal? Is B- just grounded in your multiplexer so this will work?

For anyone who is interested in or struggling with NMEA wiring, I have added
a page to my website, explaining how to connect different instruments
together. Especially how to connect two-wire (differentail) to single wire
(single-ended) and vice-versa is covered.
