NMEA 2000

Considerations
NOTICE
If you have an existing NMEA 2000 network on your boat, it
should already be connected to power. Do not connect the
NMEA 2000 power cable to an existing NMEA 2000 network,
because only one power source should be connected to a
NMEA 2000 network.
If you are installing a NMEA 2000 power cable, you must
connect it to the boat ignition switch or through another in-line
switch. NMEA 2000 devices will drain your battery if the NMEA
2000 power cable is connected to the battery directly.
NMEA 2000 compatible models can connect to a NMEA 2000
network on your boat to share data from NMEA 2000 compatible
devices such as sensors or a VHF radio. The necessary NMEA
2000 cables and connectors are sold separately.
If you are unfamiliar with NMEA 2000, you should read the
“NMEA 2000 Network Fundamentals” chapter of the Technical
Reference for NMEA 2000 Products. To download this
document, go to www.garmin.com and select Manuals on the
product page for your device.
The port labeled NMEA 2000 on the cradle is used to connect it
to a standard NMEA 2000 network.
NOTE: The echoMAP CHIRP 50 requires the included 4-pin to
5-pin adapter cable to connect to the NMEA 2000 network.

Wiring Harness
• The wiring harness is used for NMEA
®
0183 devices, and to
share route and waypoint information.
• The wiring harness connects the device to power and NMEA
0183 devices.
• The device has one internal NMEA 0183 port that is used to
connect to NMEA 0183 compliant devices.
• If it is necessary to extend the power and ground wires, you
must use 0.82 mm
2
(18 AWG) or larger wire.
• If it is necessary to extend the NMEA 0183 or alarm wires,
you must use .33 mm
2
(22 AWG) wire.
