Humminbird AS EC 20E Ethernet Cable

The Humminbird AS EC 20E is a 20 feet ethernet cable designed for marine electronics. It creates a wired link between two ethernet-capable Humminbird units for data sharing. The cable weighs 1.75 units and carries part number 720073-3. It is a new component intended for boat networking installations.

Installers connecting compatible Humminbird displays

This cable suits boat owners joining two ethernet-enabled Humminbird devices for chart or sonar sharing. It is not for buyers needing wireless connectivity or longer cable runs than twenty feet. Installers requiring different connector types or non-Humminbird equipment should look elsewhere. The product serves a single dedicated networking purpose.

Twenty-foot length for unit-to-unit connection

The defining specification is the 20 feet cable length between two ethernet ports. This fixed distance determines if the cable reaches between your mounting locations. No other lengths or cable types are included in this package. Verify the span on your vessel matches this exact measurement before purchase.

Questions about this item

Should I choose the 20 ft length or a shorter cable for my setup?

The 20 ft length suits installations where units are mounted far apart; measure the routing path first and add slack for vibration and connector strain relief.

What does the 20 ft specification mean when the cable is installed on a boat?

It provides up to 20 feet of reach between two Ethernet-capable Humminbird units, allowing flexible placement across the helm, bow or transom while maintaining a solid wired link.

Which Ethernet standard does this cable use and what speed does it support?

It is a standard Ethernet patch cable designed to connect two compatible Humminbird units; the actual data rate depends on the units’ own network interfaces.
