Nexus NX2 Installation And Operation Manual page 49

Note! The WPL (WayPoint Location) sentence, only contains the position of
the destination Waypoint. All other Waypoints will be sent out when the SEND-
WP function is activated in the SETUP.
Waypoint ID's are equal to the true (none banked) WP number in the NEXUS
Network (with digits). There is no Waypoint Base Number as in the Server-
Unit.
Input
The NMEA input in the GPS navigator instrument is exclusively used for
POSITION and NAVIGATION data (including Waypoints).
The received data is divided into three categories:
Basic POSITION related data: POSITION, SOG/COG, TIME/DATE and a
1)
limited satellite status if the sender is a GPS.
This information is received and sent out on to the NEXUS Network, but ONLY
IF the NMEA-POS is selected in the CONFiGuration SETUP.
2) NAVIGATION data: BTW, DTW, BOD, XTE plus Set and Drift
This information is received ONLY IF the NMEA-REPEATER is selected in the
CONFiGuration SETUP.
The GPS instrument will automatically calculate related data that is used in the
NEXUS Network, such as: Set and Drift, WCV, TTG and CTS (Coarse To
Steer).
3) WAYPOINTS: Waypoints are received from WPL sentences if the REC-
WPT is ON in the NMEA SETUP.
If the receiving GPS instrument isn't the active navigator (MASTER) the
Waypoint will automatically be sent to the active navigator through the NEXUS
Network.
See further in the Multi Control manual for using NMEA with the Nexus Server.
