To do so, attach the adapter cable's manual locking collar connector to the
Network port on the back of the GPS unit and attach the other end to an
available port on the NMEA 2000 buss, as shown in the following figure.
Lowrance unit direct connection to NMEA 2000 buss.
As soon as the unit is connected to the network, it will begin receiving
shared information. Please note the buss must be powered to operate. (See
instructions in this section for more on powering NMEA 2000 buss.)
NMEA 0183 Cable Connections
NMEA 0183 is a standard communications format for marine electronic
equipment. For example, an autopilot can connect to the NMEA inter-
face on the GlobalMap 5500C/4900M and receive positioning informa-
tion. The GlobalMap can exchange information with any device that
transmits or receives NMEA 0183 data.
See the following diagram for general wiring connections. Read your
other product’s owner’s manual for more wiring information.
NMEA 0183 Wiring Diagrams
(Data cable)
To exchange NMEA 0183 data, this unit has one NMEA 0183 version
2.0 communication port. Com port one (Com-1) can be used to receive
NMEA format GPS data. The com port can also transmit NMEA format
GPS data to another device.
The four wires for the com port are combined with the Power Supply cable
and NMEA 2000 Power cable to form the power/data cable (shown earlier).
Com-1 uses the yellow wire to transmit, the orange wire to receive and the
shield wire for signal ground. Your unit does not use the blue wire.
Com-1 wiring to receive NMEA position information
from some other GPS receiver.
