If connecting the LT-300 GNSS Receiver to a NMEA 2000 network (drop or backbone) then it is required to
use a screw-in connector as illustrated in Figure 33. The screw-in connector is in-the-box together with the
LT-300 GNSS Receiver.

The screw-in connector is connected to the communication cable by cutting the cable in the
right length, stripping the wires, screwing the specific wires to the connector, and then re-
assemble the connector again.
The screw-in connector outline is illustrated in Figure 34. The pin-out and numbering of the screw-in
connector is illustrated in Figure 35, while the wiring details for interconnection with the communication

NOTE:
The LT-300 GNSS Receiver can be configured to NMEA 2000 'Open' or 'Terminated'. The LT-

Service Tool is described in details in Configuration using LT-Service Tool on page 26.
The remaining figures in this sub-chapter does not show the screw-in connector for simplicity.
