Lowrance X135 Connection Manual

Cable connections for Lowrance X135 and X136DF, March 25, 2004
Sockets with blue socket nuts, and
cable plugs with blue locking
collars are NMEA 2000
connection types. The network
socket and optional NMEA 2000
buss adapter cable let the unit
connect to a NMEA 2000
network. The NMEA 2000 Power
cable gives you an option for
powering the network. These units
cannot transmit NMEA 0183 data
and cannot connect to an external
speaker. The NMEA 0183 data
cable, the NMEA 2000 power
cable (when unused) and the white
speaker wire should be capped
with wire nuts or electrical tape.
SP-BL speed sensor.
This is packed with the
X136DF and is optional
for the X135.
