Installation and Operation Instructions

This document shows how to connect an EP-85R storage device to a NMEA 2000 and Seasonal Fuel Used data for up to three NMEA 2000 compatible engines that output standard NMEA 2000 Fuel Rate Data.

NMEA 2000 is the communication bus standard developed by the National Marine Electronics Association (NMEA) for use in boats. Lowrance has introduced a line of products that can communicate over a NMEA 2000 network (LowranceNet).

All Lowrance NMEA 2000 capable devices are either NMEA 2000 certified or certification is pending.

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. Decide where you want to install all components before drilling any holes in your vessel.

Some sonar or GPS display units may require a software upgrade to display NMEA 2000 data correctly. For free software upgrades or additional information on the LowranceNet NMEA 2000 system, visit our web site, www.lowrance.com.

The EP-85R Storage Device.

The EP-85R consists of a red cable connector and a smart module. It accumulates fuel used data from fuel flow messages it receives from up to three engines. Fuel used data includes: Fuel Range, Fuel Used, Trip Fuel Used and Seasonal Fuel Used.

The EP-85R Storage Device, like the other LowranceNet Electronic Probe (EP) sensors, is designed for use with a NMEA 2000 network. Your sensor, however, is also compatible with LowranceNet blue connector networks. It can be added to a blue connector network by using a red female to blue female adapter cable. Your sensor MUST be connected to a NMEA 2000 network or it WILL NOT function.

The NMEA 2000 red female to blue female adapter cable allows users

to add red connector devices to a blue connector network.

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.

For complete instructions on setting up a new NMEA 2000 network or expanding an existing one, see the other document packed with your EP-85R Storage Device, "Setup and Installation of NMEA 2000 Networks, General Information," part number 988-0154-173. If that document is not available, it can be downloaded free at www.lowrance.com.

Installation

To install the EP-85R 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 NMEA 2000 network is a communications link between two or more devices that transfer NMEA 2000 information. LowranceNET is the NMEA 2000 networking system developed by Lowrance Electronics. A NMEA 2000 network functions like the phone wiring in a house. If, for example, you pick up a phone in the living room you will be able to hear the conversation someone is having on a phone in the bedroom.

In similar fashion, a NMEA 2000 network allows multiple display units to receive data from a GPS antenna or multiple sonar units to receive messages sent by a temperature sensor. A NMEA 2000 network gives you the flexibility to view information like engine diagnostics and fuel level data on digital gauges or display units located anywhere on your boat.

There are two types of LowranceNet red connectors: the single T

connector (left) and the double T connector (right).

Network Backbone and Network Nodes

A network bus backbone consists of network cabling, terminators and T connectors. Network nodes are made by fitting T-shaped connectors into the backbone (using the sockets on the sides) and attaching any network device to the bottom of the T.

Staying with the previous phone wiring example, T connectors on the backbone are the equivalent of phone jacks spread throughout a house. To pick up a phone and be able to hear a conversation from another phone in the house, both phones have to be connected to the main phone line. In similar fashion, only sensors and display units plugged into the NMEA network can share information. The network backbone is like the phone wiring that runs throughout a home.

It connects the network nodes, allowing them to communicate across the network. Connections found in the middle of the bus could have T connectors or backbone network cable plugged into one or both sides.

Connections at the end of a network will have the backbone cable plugged into one side and a terminator plugged into the other, as shown in the following figure.

NOTE:

If you have a double T Connector on your network that is not attached to a device, you must cap the unused connector with a NMEA 2000 cap. This will protect the pin connectors from corrosion. The NMEA 2000 cap looks like a terminator, but has "Cap" stamped into the connector housing.

All T connectors on your network probably will be connected to a device. If you want to add another node to a working network, add another T connector. T connectors may be purchased from LEI (ordering information appears on the back page of this booklet). If you are adding a Lowrance or LEI NMEA 2000 sensor, it will come with a T connector.

Adding a Network Node

You can add a node to any existing connection, anywhere along the network backbone. This connection could be 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, separate the sockets of the existing connection and install the T connector between them. If you want to add a node at the end of the backbone (network bus) remove the terminator from the last connector, like the figure above. Install the new T connector and attach the terminator to the side of the connector.

Use T-connector or double T connector to add device to bus (maintaining linear architecture)

Attach terminator at end of bus

In this example, a new device is added to the NMEA 2000 bus by

installing a T connector between a T connector and a terminator at the

end of the backbone (network bus).
