A027 to Raymarine C80 works great—solved, also discussed iNavx

I can confirm that my new A027 AIS works well with my older existing Raymarine C80 chartplotter. The unit powers on using a seatalk data cable coupled into the existing seatalk network. I at first had a hard time tracing my raymarine wiring to link the nmea out from the A027 but once i settled that, the AIS data displayed well. I did have to reverse the +/- wires from the A027 to the NMEA wires on the C80 NMEA cable. My C80 had a NMEA cable already connected with the end of the cable wiring hooked to nothing. I found that the -green and white wires from the old NMEA 0183 cable, are the NMEA inputs +/-. Now comes the process of running the additional wires from the helm to the device which is down below at the nav station. This forum helped , thanks.
