For connection of NMEA instrument IN to Server, (see Server Manual).
All data (POSITION, BTW, SOG/COG, etc.) is received from one type of NMEA
sentence. If data is placed in different locations, the data will be selected from the
sentence with the highest priority.
Example I: Position is read in priority order: GGA, GLL and. RMC.
Example II: BTW/DTW is priority first with: RMB, BWC and BWR.
The transmission ID (the first two letters after "$") is ignored by the Server. Present
position is read, after that possible latitude and longitude correction is added (C39 and
C40) before the position is sent over the Nexus Network to all instruments
