Hello, I have a Matsutec HP-528A AIS transponder that I want to connect to my Garmin Echomap 70DV chartplotter via NMEA0183
The HP-528A has RS232 or RS422 TX ports for NMEA0183 but I do not know if the Garmin NMEA RX wiring is RS232 or RS422? does anyone know which one it is?
I have included pictures of the NMEA ports
Top cable is GARMIN
Bottom pins are HP-528A
Thank Ian
