The link below opens a PDF file that gives a visual of how the NMEA network should be setup. Only the 5 port switch and the NMEA Black box are actually Humminbird parts. You can purchase the Lowrance NMEA 2000 network starter kit to establish the NMEA 2000 network. The starter kit runs around $70. (Lowrance part # 124-69)
The Humminbird black box is part number 408390-1.
Your Lowrance / Evinrude engine interface cable that connects from your outboard (provided you have the ECM) to the NMEA 2000 backbone is part number 120-62.
The Humminbird 5 port switch pictured in the diagram is part # 408450-1.
Hope this helps...... Brian
