Electrical Isolation

The GNSS Compass's power supply circuit is galvanically isolated from the communication lines.
Additionally the plastic enclosure isolates the electronics mechanically from the vessel, addressing
the issue of vessel hull electrolysis.

NMEA 2000 Drop Cable

The NMEA 2000 cable is only compatible with GNSS Compass part numbers GC-SER-LC and
GC-SER-HA. It has part number GC-NMEA2000-CABLE-6M.
The NMEA 2000 cable is used to connect serial variant GNSS Compasses to an NMEA 2000
network. Connection to the GNSS Compass is made through a Holin C-Size 18 pin connector. The
Holin part number is CCN-L218SM. The connector has a bayonet lock and provides a reliable and
rugged connection to the GNSS Compass under demanding conditions. It is rated to IP68 in the
mated condition. The opposite end of the cable is a 5 pin male Micro-C connector as per the NMEA
2000 standard. The cable is 6 metres long, dual shielded and UV stable.
