Pub. 988-0154-442 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 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.
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 connector and the smart module, which converts analog temperature data to NMEA 2000 data format.
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 composition of your transom. Required supplies for this job include: high quality, marine grade aboveor below-waterline sealant/adhesive compound.
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 sealant/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.

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.
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.
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.
