3 NMEA/SeaTalk Connections
Chapter 3: NMEA/SeaTalk Connections
The sections in this chapter explain how to connect the NMEA and
SeaTalk versions of the Raystar 120/112LP to other equipment:
3.1 Raystar 120/112LP - NMEA versions
Note: As with all on-board marine equipment, you must ensure that the
power supply connection to the Raystar 120/112LP is adequately
protected by a suitably rated fuse or circuit breaker. Usually this will be
achieved by providing power via a fused display unit.
Using the moulded 6-pin NMEA connector
The unit is normally connected to an NMEA system via the 10 m (33 ft)
cable terminated with a moulded 6-pin connector (see Figure 3-1). Use
this connector if your equipment has a compatible GPS port.
