CAN Wiring - A Practical Reference Guide

Drawing 1: Simple Linear Backbone This is the most common and ideal layout. It's simple, efficient, and easy to troubleshoot. Description: • A single, straight backbone connects all devices. • A 120-Ohm terminator is placed at each end. • Power is inserted near the middle of the backbone to ensure even voltage distribution. • The drop cables are short and connect each device to the main line.

Drawing 2: "L-Shaped" Backbone with Varied Drop Lengths This layout is more realistic for installations where the backbone needs to navigate around corners, like from a helm console down into an engine room or bilge area. Description: • The backbone cable itself can bend and be routed as needed. The key is that it remains a single, continuous electrical path. • The terminators are still at the physical ends of the entire backbone, regardless of its shape. • This example clearly shows different drop cable lengths, all of which are acceptable as long as
