Pack Assembly
Your unit is packed with a 2-foot blue-to-red adapter cable, making it
compatible with NMEA 2000 standard DeviceNet networks. Networks
consisting of LowranceNet™ red connectors and Micro-C™ connectors
are examples of a DeviceNet network. Your unit is also compatible with
LowranceNet blue connector networks.
To add your unit to a NMEA 2000 DeviceNet network, the blue end of
the blue-to-red adapter cable must be connected to the unit's network
socket; otherwise you will not be able to use the red connector cables and
devices that came with your unit. Red connector components packed with
the unit include: 15-foot extension cable, LGC-3000 GPS module, double
T connector and two 120-ohm terminators. Instructions and diagrams
covering the use of items packed with your unit are contained in the Power
Connections segment below.
1
Power Connections
Your unit comes with a power/data cable that splits into three
branches, each with several exposed wires.
The thicker three-wire cable (white, red and black) is the power supply
for your display unit. This cable has no label.
The thinner branch with three wires (red, black and shield) is the
power cable for a NMEA 2000 network. It is labeled "NMEA 2000
POWER."
The branch with four wires (blue, yellow, orange, and shield) is a data
cable, labeled "RS-232 COMM." It supports a serial communication
port. This allows your unit to exchange NMEA 0183 data with another
device, such as an autopilot, DSC marine radio or computer.
NOTE:
There are two basic power connection options, which are shown in
the following two diagrams. Read the following instructions
carefully to determine which power connection applies to
your unit. Depending on your configuration, you may not use all of
these wires.

Caution:
All of the wires in the power/data cable have bare ends for easier installation. The bare ends on any unused wires could cause
an electrical short if left exposed. To prevent this, you should
cover the individual wire ends – either by capping them with
wire nuts, wrapping them with electrical tape or both. (You
should cut off the bare wire before taping off the ends.)

Powering Your Display Unit
The display unit works from a 12-volt DC battery system. Attach the
display power cable (with provided 3-amp fuse) to an accessory switch
or power bus. If this results in electrical interference, connect direct to
a battery but install an in-line switch on the cable.
Caution:
We strongly recommend that you shut off the power supply to the
power cable when the unit is not in use, especially in saltwater environments. When the unit is turned off but still connected to a
power supply, electrolysis can occur in the power cable plug. This
may result in corrosion of the plug body along with the electrical
contacts in the cable and the unit's power socket. Risk of electrolysis corrosion is even greater when the cable is unplugged from the
unit, but still connected to a power source. We recommend you
connect the power cable to the auxiliary power switch included
in most boat designs. If that results in electrical interference, or
if such a switch is not available, we recommend connecting direct to the battery and installing an in-line switch. This will let
you shut off power to the power cable when the unit is not in use.
When you are not using the unit, you should always shut off
power to the power cable, especially when the power cable is disconnected from the unit.
WARNING:
This product must be independently fused with the enclosed 3-amp fuse (or equivalent), even if you connect to
a fused accessory or power bus.
If a malfunction happens inside the unit, extensive damage can occur if the enclosed fuse is not used. As with all
electrical devices, this unit could be damaged to a point
that it is unrepairable and could even cause harm to the
user when not properly fused.
Failure to use a 3-amp fuse will void your warranty.
If possible, keep the power cable away from other boat wiring, especially
the engine's wires. This will provide the best isolation from electrical
noise. If the cable is not long enough, splice #18 gauge wire onto it.
The display power cable has three wires, white, red and black. Red is the
positive (+) lead, black is negative (–) or ground. The white wire is unused by your unit and should be capped. Make sure to attach the in-line
fuse holder to the red lead as close to the power source as possible.
3
For example, if you have to extend the power cable to the power bus or
p
battery, attach one end of the fuse holder directly to the power bus or
battery. This will protect both the unit and the power cable in the event
of a short.
This unit has reverse polarity protection. No damage will occur if the
power wires are reversed. However, the unit will not work until the
wires are attached correctly.

Use this method if you are powering the display unit and a GPS mod-
ule or the display unit and a NMEA 2000 network. (Fuses may be dif-
ferent from those shown.)
The network and any NMEA 2000 devices, including the GPS
module, will not operate
unless the NMEA 2000 Power Cable is
connected to power. The NMEA 2000 power cable must be connected
to power even if your only NMEA 2000 device is the GPS module and it
is connected to the display unit's Network socket. (However, never
connect multiple power sources to a NMEA 2000 network.
The method in diagram B is also used when your display unit is connected to a NMEA 2000 network that is already connected to power.
(Never connect multiple power sources to a NMEA 2000 network.)

Powering a NMEA 2000 Network Bus
A NMEA 2000 bus must be connected to a power source to operate.
NMEA 2000 devices, including GPS modules, draw their power from
the network bus. If you have a pre-existing NMEA 2000 network installation, it may already be connected to another power source. If you are
not sure about a network's power status, consult the boat manufacturer
or dealer. If your NMEA 2000 bus is already powered, you can ignore the
NMEA 2000 Power cable and use the method shown in Power Diagram
B. Never attach two power sources to a single NMEA 2000 bus.

If you do need to power your NMEA 2000 bus, attach the NMEA 2000
Power cable to an accessory switch as indicated in power diagram A on
page 4. The NMEA 2000 Power cable's red wire should be attached
(with provided 3-amp fuse) to the positive (+) terminal. The NMEA
2000 Power cable's black and shield wires should both be attached to
the negative (–) terminal.
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
5
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.
GPS Antenna/Receiver Module
Your unit packs with the LGC-3000 GPS module. This device contains
the unit's external antenna and receiver for GPS and WAAS signals.
The antenna/receiver module comes with a 15-foot (4.6 m) extension
cable. This module can be mounted on a flat surface or pole, or an optional magnet is available for temporary mounting on any ferrous surface.
You need to select an antenna installation location that has a clear, unobstructed view of the sky. After the module is installed, connect it to the
unit. The LGC-3000 can communicate with your GPS unit either directly
(using the supplied extension cable) or through a NMEA 2000 network.
LGC-3000 Module, bottom view (left) and top view (right).
NOTE
See the module’s instruction sheet, publication part number 9880154-651, for complete installation instructions.
To use the module in an automobile, you may achieve good results by
simply placing the external antenna on the top of the dash, at the base of
the windshield. A piece of the rubber non-skid shelf liner material available in recreational vehicle supply stores will help hold the antenna in
place. This may not work well if you have a cab-over design pickup truck
camper or motor home. If dashboard reception is poor, simply relocate
the antenna module elsewhere on the vehicle for a clearer view of the
sky.
Connecting to a NMEA 2000 Network
A network bus is an installed and operational network cable (backbone)
running the length of your boat, already connected to a power supply and
properly terminated. Such a bus provides network connection nodes at
various locations around your boat. The NMEA 2000 network is similar to
6
the telephone wiring in a house. If you pick up a phone in your living room,
Y
you can hear someone talking into the phone in the bedroom.
Lowrance and LEI provide all the cables you will need to create a NMEA
2000 network. Lowrance provides T connectors and extension cables so
you can add devices along the backbone wherever you want. Once you
have a working network, every sensor added will come with its own T
connector for easy expansion.
The simplest NMEA 2000 network is a GPS or sonar/GPS display unit
with the LGC-3000, one double-T connector, two 120 ohm terminators
and any extension cables needed to connect them.
It is easy to expand this network by removing a terminator from one end
of the double T connector, then inserting a new T connector or extension
cable between the double T connector and terminator (See the NMEA
200 network general information document that came with your unit for
more information). For more information on connecting your unit to an
existing NMEA 2000 network, see the NMEA 2000 Networks General Information document that was packed with your unit, publication part
number 988-0154-173.
NMEA 0183 Wiring
(Data cable)
To exchange NMEA 0183 data, this unit 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 transmit NMEA format
GPS data to another device.

(shown earlier). 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.
