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

LowranceNET Node Kit for a NMEA 2000 network. Includes a 2-foot  
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.  
Suggested  
location  
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.  
Use T-connector or double T connector to add  
device to bus (maintaining linear architecture)

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

Temp Configuration  
All NMEA 2000 capable Lowrance sonar and sonar/GPS combo display  
units can be used to configure your EP-80R TH thru-hull temp sensor  
on a NMEA 2000 network.  
The LMS-525cDF is one of many Lowrance display units that may be  
used to configure an EP-80R TH thru-hull temp sensor.  
NMEA 2000 Menu/Networking Menu  
Your unit may have a NMEA 2000 menu or a Networking menu, de-  
pending on the software version installed in your unit. Both menus al-  
low you to perform the same NMEA 2000 related functions.  
NOTE:  
Some of the menus shown in this section may differ slightly from  
the menus in your display unit, but your unit will perform the same  
functions in a similar manner.  
Bus Setup  
Selecting Bus Setup from the NMEA 2000 or Networking menu will  
open the Bus Configuration menu. The Bus Configuration menu gives
