NKE NMEA output interface allows the conversion of the Topline data present on the NMEA data bus, so as to allow the interfacing between Topline network and the equipment from a different manufacturer. When the NMEA output interface is connected to the COM port of a PC with navigationsoftware, the navigation information (heading and distance to Waypoint, cross-track error) may be resent from the same COM port on the Topline network.
