Sockets with blue socket nuts,
and cable plugs with blue
locking collars are NMEA 2000
connection types. However, the
X125 and X126DF do not have a
NMEA 2000 network socket or a
communications port. These
units cannot connect to a NMEA
2000 network and cannot
transmit NMEA 0183 data. The
NMEA 0183 data cable, the
NMEA 2000 power cable and
the white speaker wire are
unused and should be capped
with wire nuts or electrical tape.
Blue
Main Power Supply Cable.
Cable has no label, but is
thickest of the three.
Three wires red (+), black
(– ground), white. White is
external speaker wire, not
used in these units.
