another interface question. I am going to interface an icm 505, with a garmin 4212 plotter,replaceing the navman 7100 radio. I am stuck on the nmea interfacing. On the icom there are red in+ and white out+cables and both cables
have an earth sheathing, this is what is confusing me. I know that the red in goes to out on the plotter and white out goes to in on the plotter.but what do i do with the outer earth sheathing from each cable, Do i just twist the earths and send it to the buz bar. Any help gratefully recieved
The existing navman nmea cables didnt have the earth sheating.which is why i am stuck.
