Connecting
The LT-300 GNSS Receiver connector and cable interconnect details are listed in Table 2 and Figure 3.
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 3.
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 configuration of NMEA 2000 ‘Terminated’.
Configuration
Use the LT-Service Tool for optional configuration of the LT-300 GNSS Receiver. The LT-Service Tool is a PC
program which may run on any Windows PC. The LT-Service Tool is connected to the LT-300 GNSS Receiver
via the NMEA 0183 interface, see Figure 4.
