Using the NGW-1 with Waypoints
If you want to use the NGW-1 with NMEA 0183 waypoint names, they have to be purely numeric – e.g. a valid waypoint name is “73”, an invalid name is “waypoint 73” in order for the NGW-1 to correctly convert it to NMEA 2000. This is because NMEA 2000 waypoint names can only be numeric (at their lowest level). Converting NMEA 2000 waypoint names to NMEA 0183 is simple as they will automatically use the numeric value defined in NMEA 2000.
All of the “next waypoint” data is converted (via APB and RMB) by the NGW-1 but a full waypoint list transfer is currently not (as WPL is not supported). We have received a number of reports from NGW-1 customers and UK Raymarine engineers that the NGW-1 works well with their Evolution autopilot.
