EP-90R Pressure
Electronic Sensor
Installation and Configuration Instructions
This document shows how to install an EP-90R Pressure sensor and
®
how to connect it to a NMEA 2000 network. It also provides
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 intro

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. It can be added to a blue connector network by using a red female to blue female adapter cable. Your sensor MUST be connected to a NMEA 2000 network or

For complete instructions on setting up a new NMEA 2000 network or expanding an existing one, see the other document packed with your EP-90R, "Setup and Installation of NMEA 2000 Networks, General Information" part number 988-0154-173. If that document is not available, it can be downloaded free from the Lowrance web site. Installation The EP-90R Pressure sensor can provide pressure data for the following categories: Atmospheric Pressure, Engine Boost Pressure, Engine Oil Pressure, Engin

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. 5. The EP-90R is ready to be connected to NMEA 2000 network. If the NMEA 2000 network backbone is in another part of the boat, the EP- 90R can be linked to the display unit at the console — if one is present — or

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. There are two types of LowranceNet red connectors: the single T connector (left) and the double T connector (right). Network B

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" s
