NMEA 0183 Baud Rate
The NMEA 0183 baud rate is configured by selecting the input level of the NMEA 0183 Rx signals (RxD+/RxD-),
see Table 5.
IMPORTANT: It is important that both RxD+ and RxD- have the same input level (floating or grounded). For
LT-300 interconnect details (wire colors), see Table 4 on page 19.
NMEA 2000 ‘Open’ or ‘Terminated’
The LT-300 GNSS Receiver is configured to ‘Open’ (NMEA 2000) from the factory. The LT-Service Tool can be
used for setting NMEA 2000 bus termination for the LT-300 GNSS Receiver.
IMPORTANT: Use the LT-Service Tool to configure the NMEA 2000 bus termination to ‘Terminated’. For
further information on the LT-Service Tool, see Configuration using LT-Service Tool on page
26.
