Weatherproofing The Ethernet Hub
Depending on the mounting location for the hub, it is strongly recommended to weatherproof
the Ethernet hub by placing it in a splash-proof or waterproof box.
Hubs have no settings or adjustments, so there should not be a reason to access them
after installation other than to confirm or check the status of the network.
Ethernet hubs and RJ45 connectors all have gold plated contacts that will not corrode.
We are actively working on a “Furuno Supplied Weatherproof Hub”. It will consist of one of
our approved hubs mounted in a waterproof housing. Until this hub is available, please be
sure to arrange a suitable way to prevent water damage to the hubs that you install.

Approved Ethernet 10BASE-T Hubs and Hub Information
Furuno will only specify 4, 5, or 6, port Ethernet 10BASE-T hubs that we have tested and can
be powered directly from the +12VDC Output of any NavNet Display. However, technically,
any Ethernet 10BASE-T or 10/100BASE-T Hub is compatible with NavNet Products. If you
have a stable power source available any hub will work.
DANGER: Do Not Attempt to Source More than 250mA from either of the two NavNet
Display 12VDC Ports. Each Port can safely supply 250mA for connected sensors or hubs
(i.e. BBGPS & Hub, BBGPS & Smart Sensor, GP36 Sensor Mode & Hub, etc…)
- The hubs below consume less than 250mA@12VDC and are OK to be powered
by any NavNet Display. They can also be powered by +12VDC directly.
- Do not use “Dedicated Uplink” Ports on any Hub
- The Black/White Stripe Wire from AC Adapter is +12VDC on the hubs below
