NMEA 2000 network. If you do not have an existing NMEA 2000
network you can create a basic one using cables from Garmin.
If you are unfamiliar with NMEA 2000, you should read the
"NMEA 2000 Network Fundamentals" chapter of the Technical
Reference for NMEA 2000 Products. You can find this document
using the "Manuals" link on the product page for your device at
www.garmin.com.
The port labeled NMEA 2000 is used to connect the device to a
standard NMEA 2000 network.

NMEA 0183 Connection Considerations
• There is one internal NMEA 0183 input port (RX port) and
one internal NMEA 0183 output port (TX port) on the included
NMEA 0183 data cable. You can connect one NMEA 0183
device to the internal RX port to input data to this Garmin
device, and you can connect up to three NMEA 0183 devices
in parallel to the internal TX port to receive data output by this
Garmin device.
• See the installation instructions for the NMEA 0183 device to
identify the transmit (TX) and receive (RX) wires.
• The device provides one TX port and one RX port. Each
internal port has 2 wires, labeled A and B according to the
NMEA 0183 convention. The corresponding A and B wires of
each internal port should be connected to the A (+) and B (-)
wires of the NMEA 0183 device.
• You must use 28 AWG, shielded, twisted-pair wiring for
extended runs of wire. Solder all connections and seal them
with heat-shrink tubing.
• Do not connect the NMEA 0183 data wires from this device
to power ground.
• The power cable from this device and the NMEA 0183
devices must be connected to a common power ground.
• For two-way communication with a NMEA 0183 device, the
internal ports on the NMEA 0183 data cable are not linked.
For example, if the input of the NMEA 0183 device is
connected to TXA on the data cable, you can connect the
output port of your NMEA 0183 device to the input port on the
wiring harness.

• See
NMEA 0183 Information, page 6
approved NMEA 0183 sentences that are output by and input
to this device.
• The internal NMEA 0183 ports and communication protocols
are configured on the connected Garmin device. See the
NMEA 0183 section of the chartplotter owner's manual for
more information.
NMEA 0183 Device Connections
This diagram illustrates two-way connections for both sending
and receiving data. You can also use this diagram for one-way
communication. To receive information from a NMEA 0183
