EP-80R Temp

Electronic Temperature Sensor

Installation and Configuration Instructions

This document shows how to install an EP-80R temp sensor and how to

connect it to a NMEA 2000®network. It also provides instructions on

how to configure your temp sensor with Lowrance digital gauges (LMF-

200 & LMF-400) and display units.

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®network

system, visit our web site, www.lowrance.com.

NMEA 2000 red

cable connector

The EP-80R consists of the temp sensor module, a red cable connector

and the smart module, which converts analog temperature data to

NMEA 2000 data format. The cable length measures 18 inches (46 cm)

from the connector to the smart module and 10 feet (3 meters) from the

smart module to the temp module. The EP-80R Temp, 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.

One way or another, 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

NMEA 2000 LowranceNet 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 need to

purchase a LowranceNET Node Kit.

For complete instructions on setting up a new NMEA 2000 network or

expanding an existing one, see the NMEA 2000 document packed with

your EP-80R Temp, "Setup and Installation of NMEA 2000 Networks,

General Information," part number 988-0154-173. If that document is

missing, it can be downloaded free from the Lowrance web site.

Other supplies are not included, unless otherwise indicated. A transom

mount requires one #8 stainless steel screw (3/4" long) and a high

quality, marine-grade above- or below-waterline sealant/adhesive

compound. If you need a pilot hole for the screw, use a drill and a 1/8"

drill bit. If you want to feed the temp module through a transom or

bulkhead, use a 3/4" bit. A screwdriver is needed for mounting the temp

sensor.

extension cable, T connector and two 120-ohm terminators.

Installation

The EP-80R temperature sensor can be mounted in any location where

you want temperature to be monitored. The most common applications

are transom mounts — to measure surface water temperature — or in

a livewell. Wherever you install it, make sure the temp module will be

in contact with the water at all times. If the sensor is mounted on the

transom, make sure it is mounted in a manner that prevents it from

coming into contact with the boat trailer.

Caution:

If you drill a hole in the transom for the cable, make sure it is

located above the waterline. After installation, be sure to seal the

cable hole with the same marine grade above-or below-waterline

sealant used for the screw.

Notice that the sensor was routed so the smart module is inboard.

After determining the location, use the temp module as a template and

mark the hull for the screw's pilot hole. Route the temp module and

cable over or through the transom to the mounting location. If routing

through the transom, drill a 3/4" hole to accommodate the temp

module. Make sure the smart module is inboard and not left exposed on

the open transom. Attach the temp module to the hull with one #8

stainless steel screw and seal the screw with the below-waterline

sealant compound.

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.

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).
