Humminbird 531906-1EN_A - Manual (Page 8)

1. Installing an Ethernet Connection
If your Humminbird® control head has a built-in Ethernet connector, the unit
can be connected to the Ethernet network. When you connect the units
together, data is shared between the two units.
Before you start, please note that the Ethernet network installation has the
following requirements:
• Update Software: If your network includes a legacy Humminbird®
model, download the latest software update from your account at
humminbird.com. Legacy models include 858c, 898c SI, 998c SI, 958c,
and 1100 Series™ units.
• Install the control heads and sources (GPS, transducers, temp/speed
accessories, etc.) for your Fishing System. See the equipment installation
guides for details.
• Purchase Ethernet Connection Cables (separate purchase required):
Your network configuration will determine which Humminbird®
connection cables you will need to purchase to connect the control
heads to the network (see the Ethernet Cable Information table).
