How to use the NMEA ports

The FI-30 Server is designed with two NMEA input ports and one shared output port.
The external NMEA data will be combined with FI-30 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 FI-
30 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.
