NMEA Router is software that forwards an NMEA stream from one or several AIS receivers. It is useful for AIS partners with several receivers. Read more about the NMEA router here: http://arundale.com/docs/ais/nmearouter.html.


  • Connecting the receiver to a computer (USB, serial or network) is possible.

  • The connection method is known (COM port, IP, etc.).

  • The computer runs on Windows and is working non-stop.


  • Label the profile with a name of your choice and click OK.

  • Set up a new source (AIS receiver): Configure → Connection → New

  • Label the source (connection) with a name of your choice.

  • Choose Serial as the Type of Connection if the AIS receiver is serial or connected via USB.

  • Click OK to continue.

  • The Serial Port Configuration window will appear.

  • Choose the COM port your receiver is connected to under Device and the Baud Rate to 38400.

  • Select Input as Data Direction.

  • Click OK to continue.

  • Set up a new data receiver: Configure → Connection → New

  • Label the data receiver, i.e. with "FleetMon".

  • As Protocol can be selected UDP or TCP.

  • As Data Direction, select Output.

  • Configure the Remote Host. An own port for statistics can be ordered here: https://www.fleetmon.com/my/ais-stations → Add my AIS station

  • Until this has been confirmed via email, data can be sent to the IP ( or ais.fleetmon.com) and port (34003) shown in the picture on the left side.

  • Save with OK.

  • Generate a route, so the data of the source can be sent to the receiver: Configure → Route → New

  • In the field Between, select which source should send to which receiver in the field And.

  • Make sure to tick the box Enabled.

  • Save with OK.

  • If the connection does not start automatically, you have to start it manually: Click on the Start button.

  • Now you can see how the data is being transferred.

  • Add NMEA Router to Startup in Windows System Configuration, so you don't have to start the program manually each time.

  • You are finished! Go now to FleetMon.com and check your "My AIS Stations" page. After 5-10 minutes, the statistics of your data should be displayed.
