2. Determine the Cable Requirements
Depending on your Humminbird model and network configuration, you may need to purchase additional
accessories to connect your Radar scanner to your control head or Ethernet network. Before starting the
installation, determine whether you will need to purchase Ethernet Adapter Cables or extension cables.
Also, see Connect to Power and Ethernet for more information.
NOTE: To purchase Ethernet Accessory Cables, extension cables, or the Ethernet Switch, visit our Web site
at humminbird.com or call Humminbird Customer Service at 1-800-633-1468.
3. Create a Schematic Diagram
A schematic diagram is an essential part of planning any installation. It is also useful for any future additions
or maintenance of the system. The diagram should include the following:
• Location of all components
• Cable types, routes, and lengths.
NOTE: Confirm that you have read and understood the warnings and cautions provided in the Important
Information section before proceeding with the installation.
