Actisense 0183 to N2K Gateway w/PC Interface, USB [NGX-1-USB]0183 to N2K Gateway with PC Interface, USB The NGX 1 is an intelligent gateway that converts NMEA 0183 data to NMEA 2000 (and vice versa), allowing you to share information between devices from the two standards. This creates the possibility of upgrading some of the vessels electronics to NMEA 2000 and keeping the remaining NMEA 0183 devices. This can help spread the cost of transitioning to NMEA 2000, reducing the initial upgrade cost to accommodate
