EP-70R Speed
Electronic Speed Sensor
Installation Instructions
This document shows how to install an EP-70R speed sensor and how
to connect it to a NMEA 2000
®
network.
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
®
network
system, visit our web site, www.lowrance.com.
