A. STEP 1: Wiring the NMEA Bus

The first step in installing the NMEA bus is to define the backbone network.

To configure the main, you will need two terminators, cables with male-female connectors, T or multitap connectors, and defining a power supply connection.

Cable Basics

• Two Cable Sizes Heavy and Light
• Two Connector Styles Mini-C and Micro-C

Following our first tech note, we cover here the practical aspects of
connecting Raymarine units to NMEA2000 networks and vice versa.

In our last tech note, we talked about RPM and Alternator voltage, we will now cover pressures and temperatures taken from resistive senders.
