Page 50: Special Nmea And Nexus Applications
SPECIAL NMEA AND NEXUS APPLICATIONS In some applications, you might need an EXTRA NMEA input port. This is possible by using the NEXUS Server (with one Multi Control instrument) together with one NEXUS GPS navigator instrument. This CONFIGuration will convert NMEA position to NEXUS Network and the NEXUS GPS Navigator instrument will do the Navigation. - Page 51 GPS NAVIGATOR NMEA INPUT The NEXUS GPS NAVIGATOR input port (normally used as the NMEA 0183 input) can also be set to receive the RTCM 104 messages for the SILVA GPS COMPASS. It is preferable to use 4800 baud on the RTCM data to utilise the NMEA 0183 standard output data specified at this baud-rate.
- Page 52 NEXUS NAVIGATOR's memory. SPECIAL USE TO GET EXTRA WP's. When two or more navigator instruments are connected to the NEXUS Network and if more than one "skipper" or family are using the boat, it is sometimes practical to utilise two completely separate WP bank's.
- Page 53 EXTRA FEATURES WITH SILVA NEXUS NETWORK Integrate the navigator with the NEXUS Multi Control and Server by adding compass and speed transducers. You will then get compass heading, boat speed, drift and tidal data (its speed and direction).
