[CA] E120 data feed, move from Seatalk 1 to Seatalk ng

[Chuck - Raymarine - Moderator]

Lothar,

Don't assume that the ST-STng Converter's software level is the latest. Instead, download it from Raymarine's website and update its software via the E120 MFD. The ST-STng Converter will bridge critical GPS data from SeaTalk to SeaTalkng / NMEA 2000, and this critical data should most certainly include the vessel's lat/lon coordinates, COG, SOG, and HDOP. However, non-critical data will not be bridged. As has been indicated within related FAQs within this Forum, the SeaTalk to SeaTalkng Converter's software does not support bridging of the following non-critical GPS sensor data to SeaTalk:
- Satellite Status
- Sky View
- FIX rather than SD FIX will be reported within the FIX Status field when a WAAS GPS FIX has been acquired

All other GPS data items (lat, lon, UTC Date, UTC Time, HDOP, and Mode) will be correctly reported. When determining the accuracy of the GPS position FIX, HDOP will be used. When a Raystar 130/150 GPS Sensor is installed in a location affording it an unobstructed view of the skies overhead, the Raystar 130/150 GPS Sensor will typically provide the system with a HDOP less than or equal to 1.0 (lower HDOP equates to higher accuracy).
