For further details on NMEA 2000 setting, see NMEA 2000 ‘Open’ or ‘Terminated’ on page 20.

Using NMEA 2000 - check your navigational equipment for correct selection of the LT-300 GNSS
Receiver as preferred source (GPS/GNSS). Check that the LT-300 GNSS Receiver is supporting the

a.
Write “status” and check for errors and warnings

If any configuration has been applied in the LT-Service Tool, make sure that you have used the
