Cable connections for Lowrance LMS-480
Sockets with blue socket nuts, and
cable plugs with blue locking
Sonar/GPS unit
rear view
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 0183 Data Cable.
Four wires: blue,
orange, yellow, shield
(bare). Cable label says
"RS-232 COMM."
LGC-2000 25'
Extension Cable
NMEA 2000 Power Cable. Three wires:
red (+), black (– ground), shield (bare,
– ground). Cable label says "NMEA
2000 Power." Used to power the GPS
module and/or a NMEA 2000 network
buss.

Cable has no label, but is
thickest of the three.
Three wires: red (+), black

external speaker wire, not
used in these units.
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.
If sonar/GPS unit is not
connected to a powered
NMEA 2000 network, you
must connect the NMEA
2000 Power Cable to a
12-volt power source in
order for the LGC-2000
to work.
