Dennis, I'm very curious about your NMEA course.

How do they tell you to hook up non-compliant devices that have one
wire for NMEA output and one wire for NMEA input to the balanced NMEA
(+) and (-) network? Did anyone talk about why some manufacturers
cheap-out like this?


I added a page to my website, which explains exactly this:
