Installation and Configuration Instructions
This document shows how to install an EP-90R Pressure sensor and
how to connect it to a NMEA 2000
instructions on how to configure your pressure 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
system, visit our web site, www.lowrance.com.

  • Page 2 The EP-90R consists of a red cable connector and the EP-90R housing with standard size hose barb attachment. The EP-90R Water Pressure sensor, like the other LowranceNet Electronic Probe (EP) sensors, is designed for use with a NMEA 2000 DeviceNet Network. Your sensor, however, is also compatible with LowranceNet blue connector networks.

  • Page 3: Installation

    NOTE: If your engine does not have a speedometer hose, you will have to purchase a pitot tube kit to use the EP-90R Pressure sensor. For pitot tube installation instructions, refer to your pitot tube installation manual. The following steps cover the recommended installation of the EP-90R.
  • Page 4 3. Slide the pressure hose onto the EP-90R hose barb attachment. If it does not fit snugly, secure it with a zip tie at the base of the hose barb attachment. 4. Now you are ready to remove the speedometer. Refer to the speedometer’s installation manual for removal instructions.
  • Page 5 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 from 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.
  • Page 6 If you want to add another node to a working network, add another T connector. T connectors may be purchased from LEI. If you are adding a Lowrance or LEI NMEA 2000 sensor, it will come with its own T connector.

  • Page 7: Additional Network Information

    Use T-connector or double T connector to add Backbone cable device to bus (maintaining linear architecture) to rest of bus Existing network node Attach terminator at end of bus Devices connect to double T 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).
