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

LowranceNET Node Kit for a NMEA 2000 network. Includes a 2-foot  
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).
