I do this with a hat...
At the Moment I recheck the NMEA0183 Ports.
I get grey hairs… I have never seen something like this. Normaly nmea uses RS422 standard or asymetric RS232 Standard.
Now I have tested a ST60+ Raymarine. This Display has a NMEA Output ( + /- ) normaly you expect that - is gnd or the B Port of the RS422. No. Raymarine ST60+ switch the ground Pin!! means + is always 12V. gnd is gnd and nothing happens. If you put the resistor (120Ohm) between, gnd is also 12V and on Data Moment switch to gnd. This isnt compatible to any Standard?????
After searching in web I´m not the one who have this problem. Why somebody do such a sh**???
