NMEA 2000 Buss Adapter Cable
and Micro-C T-shaped Connector
Installation Instructions
These instructions will help you connect a Lowrance or LEI product to an
installed NMEA 2000 network with Micro-C connectors. To do so, you
will need an adapter cable of one of the following types:
Micro-C to Lowrance Male converter.
Micro-C to Lowrance Female converter.
With either adapter cable connect the Micro-C plug (shown left in these
figures) to an available network port on your boat's NMEA 2000 buss.
Adding a Network Port
On a manufacturer's NMEA 2000 buss, network ports are T-shaped Mi-
cro-C connectors. Connectors found in the middle of the buss (near your
dash, for instance) will have one or more of these T-shaped connectors
with the network cable plugged into both sides. Connectors at the end of
the buss will have the network cable plugged into one side, and a small
terminator plugged into the other, as shown in the following figure.

All of the ports on your boat's network will probably be filled, but if you
want to add something to it, just order a Micro-C T-shaped connector
from LEI (ordering information appears on the back page of this booklet).
This T-shaped connector adds a port to your NMEA 2000 buss.

You can add a port anywhere your network buss has T-shaped connec-
tors. If you want to add in the middle of the line, then separate the net-
work cable from one end of the attached T-shaped connectors, and attach
your new T-shaped connector between them and the network cable. If
you want to add a port at the end of the line (as shown in the following
figure), remove the terminator from the very last connector, securely at-
tach the new T-shaped connector, and then replace the terminator on the
new connector. Either method will leave one new port available.
Add an empty network port to a NMEA 2000 buss by attaching a T-
shaped connector between two full ports, or between a port and the
terminator at the end of the line.
Attach the adapter cable's Micro-C connector to the new port, and the
other connector to your Lowrance or LEI product.
Connecting Lowrance Male Plug to Unit or Sensor
Most installations will use the Lowrance Male to Micro-C converter to
connect a Lowrance or LEI product directly to a network port. To con-
nect a sonar or GPS or sonar/GPS combo unit directly to a NMEA 2000
network, attach the adapter cable's Lowrance Male plug to the Network
socket on the back of the unit.
Use the buss adapter cable to connect a Lowrance unit to a network port.

To connect an LEI sensor or GPS module directly to the network, attach
the accessory's blue connector to the adapter cable's Lowrance Male plug.
Use the buss adapter cable to connect any NMEA 2000-ready
LEI or Lowrance accessory to a network port
Connecting Lowrance Female Plug to Extension Cable
With some NMEA 2000-ready GPS modules we provide a Y-adapter exten-
sion cable that will allow you to connect both the GPS unit and the GPS
module to a single NMEA 2000 network port. This installation requires the
Micro-C to Lowrance Female converter. Connect the GPS module to the
unit using the extension cable as described in the unit's manual.
LGC-2000 and GPS unit connection to NMEA 2000 buss.
The GPS module's extension cable will have a 60-ohm terminator at-
tached to the shorter branch. Remove the terminator and connect the
adapter's Lowrance Female plug to the extension cable's shorter branch.
If you do this, be sure the unit's NMEA 2000 Power cable is not con-
nected to your boat's power supply. Never connect another power
source to an operational NMEA 2000 buss. If it's working, it's al-
ready powered, and a NMEA 2000 network should never be connected
to more than one power source.
NOTE:
Keep the terminator! If you ever disconnect the NMEA 2000 net-
work connection, you'll have to re-attach the terminator in order for
the GPS module to function correctly.
