WARNING:
The NMEA 2000 network bus is always on and constantly
drawing power. You must connect NMEA power to a
switched power source so you can turn off the network
when not in use. Failure to connect to and use a power
switch will drain your boat battery, which could stop
your boat's operation.
Connecting to a NMEA 2000 Network
Your unit can be connected to a NMEA 2000 bus, receiving sensor in-
formation from units and devices attached to the network. Contact LEI
Extras (look inside back cover for accessory ordering information) for
NMEA 2000 accessories.
NOTE:
GPS data from your internal GPS receiver can not be transmitted
across a NMEA 2000 network. The only way to transmit GPS data
across the network is to add a LGC module to the network. For
more information see page 125.
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 5300c and receive positioning information. The
GlobalMap 5300c can exchange information with any device that trans-
mits 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
(Data cable)
To exchange NMEA 0183 data, the GlobalMap 5300c 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 trans-
mit 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 ear-
lier). 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.
