Sockets with blue socket nuts, and
cable plugs with blue locking
collars are NMEA 2000 connection
types. The NMEA 0183 Data Cable
can transmit NMEA position data to
another device. The Main Power
Supply Cable provides 12-volt
power for the sonar/GPS unit (the
white speaker wire is not used). The
NMEA 2000 Power Cable supplies
12-volt power to the LGC-2000
GPS antenna module and/or a
NMEA 2000 network buss. All
unused wires in the 3-way
Power/Data Cable should be capped
with wire nuts or electrical tape.

This figure corrects the drawing on page 35 in
the LMS-480 manual, part 988-0151-181. The
manual showed the sonar and power/data
sockets in the wrong place, and listed the
wrong speed sensor model.

must connect the NMEA
2000 Power Cable to a
12-volt power source in
order for the LGC-2000
to work.
