EP-50 Storage Device
Electronic Probe
Installation Instructions
This instruction sheet tells how to connect your EP-50 storage device to
a NMEA 2000network using LowranceNETnetwork components.
You must refer to your digital gauge, sonar or GPS unit's manual for
sensor operation instructions.
CAUTION:
Installing LowranceNET NMEA 2000 devices is significantly
different from installing earlier Lowrance components without
NMEA 2000 features. You should read all of the installation
instructions before proceeding. You should decide where to
install all components before drilling any holes in your vessel.
Some sonar or GPS units may require: 1. a software upgrade to display
NMEA 2000 data correctly; and 2. a manual addendum describing how
to operate the sensor. You can download these free and get additional
information on the NMEA 2000compatible LowranceNETsystem at
our web site, www.lowrance.com.
All Lowrance NMEA 2000 capable devices are either NMEA 2000
certified or certification is pending. See our web site for the latest
product status information.

The EP-50 consists of a blue female locking cable connector and a smart
module. It stores NMEA 2000 fuel information about your vessel, which
includes Fuel Used, Trip Fuel Used and Seasonal fuel usage.
Refer to your display unit’s operation manual or manual addendum for
instructions on how to clear out information stored in EP-50 storage
device memory.
The EP-50, like other Lowrance Electronic Probe (EP) sensors, is
designed only for use with a NMEA 2000 Network. It MUST be
connected to a NMEA 2000 network or it WILL NOT function.
Tools and Supplies
Your EP sensor packs with a T connector needed to attach it to a
LowranceNET NMEA 2000 network. If you are connecting to an
existing LowranceNET network, those are all the electronic
components you need. If this is the first sensor you are connecting, you
will also need a one-time purchase of a LowranceNET Node Kit.
LowranceNET Node Kit for a NMEA 2000 network. Includes a 2-foot
extension cable, T connector, 120-ohm male terminator and 120-ohm
female terminator.
For complete instructions on setting up a new NMEA 2000 network or
expanding an existing one, see the other document packed with your
EP-50 Storage Device, "Setup and Installation of NMEA 2000
Networks, General Information," part number 988-0154-172. If that
document is missing, it can be downloaded free at www.lowrance.com.
Installation
To install the EP-50 Storage device, route the sensor's cable connector
to the T on the network backbone where you intend to attach it and
plug it in.
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

3
and properly terminated. Such a bus provides network connection
nodes at various locations around your boat.
This is similar to the telephone wiring in a house. If you pick up a
phone in your living room, you can hear someone talking into the phone
in the bedroom.
Network Nodes
A network bus is built of network nodes spread along a backbone.
Network nodes are made by fitting T-shaped connectors into the
backbone (using the sockets on the sides), and attaching a display unit or
sensor at the bottom of the "T."
Using our telephone example, the T connectors are similar to telephone
jacks. The backbone is like the phone wiring running through a house.
Phones in a house must be connected to each other to communicate, and
in the same way only sensors and display units plugged into the NMEA
network can share information.
Connections found in the middle of the bus will have one or more of these
T-shaped connectors with the backbone cables plugged into both sides.
Connections at the end of a network will have the backbone plugged into
one side and a terminator plugged into the other, as shown in the
following figure.

Adding a Network Node
You can add a node anywhere along the network backbone where a
connection already exists. This connection could be at the end of the
network (between a T connector and a terminator), between two T
connectors, between a T connector and a backbone extension cable, or
between two extension cables. Wherever you want to add the new node,
simply separate the sockets of the old connection and attach your new T
connector between them.

Add a new device to a NMEA 2000 bus by attaching a T connector
between two T connectors, between a T connector and the end
terminator, or between two backbone extension cables.
If you want to add a node at the end of the line (as shown in the previous
figure), remove the terminator from the very last connector, securely
attach the new T connector, and then attach the terminator on the new
connector. Either method will allow you to add a device.
Additional Network Information
Further instructions on creating or expanding a network are included in
the NMEA 2000 network setup booklet, part number 988-0154-172,
which came packed with this instruction sheet.
