2.6How to use the NMEA ports

The NX2 Server is designed with two NMEA input ports and one shared output port. The external NMEA data will be combined with NX2 sensor data so that all information will be available on one single output NMEA port.

One NMEA port (in/out) is dedicated for your PC and follows the RS232 electrical standard. A 9-pole D-SUB connector is placed at the bottom of the Server.

The Other port (in/out) is accessed at the screw terminal and follows the NMEA 0183 electrical standard (RS422 out and opto-coupler input).

The two-port Server installation will solve most of the integration needs onboard, the installation with a GPS connected to port A and the Laptop PC on port B.

1.Position, speed and course information is taken from port A (the GPS). The Server will then pass that information plus all other boat-data to port B where the PC and chart navigation software will calculate BTW, DTW and XTE information to the NX2 instruments, radar, auto-pilot, plotter or other source.

The NMEA ports have been given different priority's depending on the type of data that will come into the Server when the same type of data comes on both ports.

Position and time (GPS) data GGA, GLL, GSA, GSV, RMC, ZDA have higher priority on port A.

Navigational data (RMB, BWC, BWR, XTE, APA, APB WPL, BOD WCV ) have higher priority on port B.

By using this feature, you may use the PC for planning and part time navigation, then allow for a GPS/ plotter to take over navigation without the need to change connections.
