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 NationalMarine 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 2000features. 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.

EP-90R Pressure Sensor.
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 alsocompatible 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 it WILL NOT function.
The NMEA 2000 red female to blue female adapter cable allows users to add red connector devices to a blue connector network.
Tools and Supplies Your EP sensor packswith a T connector needed to attach it to a LowranceNET NMEA 2000 network. If this is the first sensor you are connecting, you may also need a one-time purchase of a LowranceNET Node Kit. The following tools and supplies are NOT included. Required tools include: a utility knife. For some installations, a Phillips screwdriver will be needed. Supplies include: zip/cable tie.
LowranceNET Node Kitfor a NMEA 2000 network. Includes a 2-foot extension cable, T connector and two 120-ohm terminators.
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.

The EP-90R Pressure sensor can provide pressure data for the following categories: Atmospheric Pressure, Engine Boost Pressure, Engine Oil Pressure, Engine Water Pressure, Fuel Pressure, Transmission Oil Pressure and Pitot Speed. WARNING: The maximum pressure for an EP-90R Pressure sensor is 100 PSI (689 kPa). If that pressure level is exceededyou not only risk damaging the EP-90R, but could also suffer bodily injury. Pitot Tube (Water Speed) We recommend installing the EP-90R near the boat’s original speedometer. 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. Thefollowing steps cover the recommended installation of the EP-90R. You will attach the EP-90R to a pitot tube hose in the same manner. 1. Remove the pressure hose from the boat’s speedometer. 2. Clip off the end of the pressure hose that was connected to the speedometer. This will help ensure the pressure hose will fit snugly on the EP-90R hose barb attachment. The hose-barb attachment requires a...
