Connecting to a nmea 2000 network, Nmea 0183 cable connections – Lowrance electronic 5300c User Manual

Page 24

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.
