EP-80R TH

Electronic Thru-Hull Temp Sensor

Installation and Configuration Instructions

This document shows how to install an EP-80R TH thru-hull temp sen-

sor and how to connect it to a NMEA 2000®network. It also provides

instructions on how to configure your temp sensor with Lowrance digi-

tal gauges (LMF-200 & LMF-400) and display units.

NMEA 2000 is the communication bus standard developed by the Na-

tional 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 certi-

fied 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 in-

structions before proceeding. Decide where you want to install

all components before drilling any holes in your vessel.

Some sonar or GPS 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.

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

tor 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 TH temp sensor is de-

signed to operate in a temperature range of 4°to 176°F (-20°to 80°C).

Like other LowranceNet Electronic Probe (EP) sensors, your thru-hull

temp is designed for use with a NMEA 2000 Network. Your sensor,

however, is also compatible with LowranceNet blue connector net-

works. It can be added to a blue connector network by using a red fe-

male 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.

Caution:

The maximum hull thickness for the EP-80R TH is 1-1/4" (31

mm).

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 pur-

chase 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 TH temp, "Setup and Installation of NMEA 2000 Net-

works, General Information," part number 988-0154-173. If that docu-

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

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

Recommended Tools and supplies

Recommended tools for this job include: drill, 1/8" (3 mm) drill bit for pilot

hole, 1-1/16 (27 mm) hole saw with a blade type appropriate for the com-

position of your transom.

Required supplies for this job include: high quality, marine grade above-

or below-waterline sealant/adhesive compound. We recommend 3M Poly-

urethane Marine Adhesive Sealant 5200 or an equivalent brand. The sen-

sor is packed with a lock nut used for mounting.

Installation

1. The EP-80R TH thru-hull temperature sensor can be mounted in any

location on the hull, with the most common application being on the

transom. Wherever you install it, make sure the temp module will be in

contact with the water at all times and that it does not interfere with

the boat's trailer.

To install the EP-80R TH, use a hole saw to cut a 1-1/16" (27 mm) hole in

the transom. The hole should be below the waterline.

2. After you've determined the proper location on the transom for the

EP-80R TH, drill a 1/8" (3 mm) pilot hole from inside the transom.

3. The EP-80R TH requires a 1-1/16" (27 mm) hole. Using a hole saw,

drill from the outside of the transom to prevent the gel coat from crack-

ing on fiberglass boats. Use eye and face protection when drilling the

hole.

Afterwards, clean the area around the hole with detergent or alcohol.

This will establish a good surface for the adhesive.

5. Using a high quality, marine-grade above- or below-waterline seal-

ant/adhesive compound, apply a 1/8" (3 mm) bead of sealant around the

lip of the EP-80R TH housing.

6. Make sure the nut has been removed from the sensor module, then

from the outside of the transom, pass the EP-80R TH cable through the

hole and push the housing with sealant into it. Use a twisting motion

to squeeze out excess sealant. Remove excess sealant from the outside

of the transom before it dries.

Slide the nut over the red connector (left); Place the nut on the sensor

module, add sealant on the inside of the hull and tighten the nut

(right).

7. On the inside of the hull, slide the nut over the back end of the sen-

sor module and add a 1/8" bead of sealant around the edge of the hole

on the inside of the transom. Hand-tighten the nut; be careful not to

over-tighten. Do not use a wrench to tighten the nut! Remove ex-

cess sealant from the inside of the hull before it dries.

8. Route the EP-80R TH cable to the T on the network backbone where

you intend to attach it, and plug it in.

NOTE:

Allow marine grade sealant/adhesive compound to dry for 12 hours

before taking your boat out on the water.

9. Check for leaks! After the boat is placed in the water, check for

leaks immediately. Check the boat for leaks again several times during

the next 24 hours. If you notice any leakage at all, the EP-80R TH

should be re-installed with a new coat of adhesive.

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 con-

nector (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 connec-

tors 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 fol-

lowing figure.

NOTE:

If you have a double T Connector on your network that is not at-

tached to a device, you must cap the unused connector with a

NMEA 2000 cap. This will protect the pin connectors from corro-

sion. 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 informa-

tion 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 net-

work 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) re-

move the terminator from the last connector, like the figure above. In-

stall 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 install-

ing a T connector between a T connector and a terminator at the end of

the backbone (network bus).

Additional Network Information

For more information on creating or expanding a network refer to the

NMEA 2000 network setup booklet, part number 988-0154-173, which

came packed with this document.
