Sunluway Ethernet Adapter Cable for Humminbird HELIX 12in

Sunluway 720074-12 AS EC QDE is a 12-inch Ethernet adapter cable that links Humminbird HELIX fish finders and One-Boat Network devices for dependable onboard data sharing.

This compact adapter cable is designed to join Ethernet-ready Humminbird HELIX units and compatible marine accessories so charts, sonar, and control signals can move between displays and devices. Built to match Humminbird connector standards and to withstand the marine environment, the adapter transforms a standard RJ45 Ethernet run into a plug-and-play connection for HELIX models and select trolling motor networks.

Which Humminbird models and systems does this adapter support?

The Sunluway AS EC QDE cable fits a wide range of HELIX displays and select legacy models. It works with HELIX 7 G2N/G3N and all HELIX 8, 9, 10, 12, and 15 series units, including common model numbers used in the field.

• Compatible with HELIX 7 G2N & G3N, HELIX 8/9/10/12/15 models
• Covers model families such as 859, 899, 959, 999, 1159, and 1199
• Interfaces with Humminbird Ethernet accessories and One-Boat Network devices

How do I use this adapter to network two fish finders?

To link two HELIX units you'll need two Sunluway AS EC QDE adapters plus a standard Ethernet cable of the correct length. Each adapter converts a unit's proprietary port to an RJ45 feed, allowing a single Ethernet cable to carry data between displays.

• Use two AS EC QDE adapters—one at each fish finder
• Install an appropriate-length Ethernet cable (not included) between adapters
• Plug-and-play setup with no soldering or special tools required

What physical and durability features does this 12" cable offer?

The 720074-12 measures one foot, giving a tidy, low-profile connection for tight helm or console installs. It uses fitted connectors and marine-grade materials to resist corrosion, flexing, and exposure common on boats.

• Precision-molded connectors for secure, vibration-resistant fit
• Durable materials formulated for saltwater and UV exposure

Will this adapter work with Minn Kota i-Pilot Link and One-Boat Network?

Yes—the adapter enables Ethernet networking between compatible Humminbird units and systems such as Minn Kota i-Pilot Link or other One-Boat Network-capable devices. Use it to share position, navigation, and control data across the onboard network.

• Enables integration with Minn Kota i-Pilot Link trolling motors
• Shares chart and sensor data across compatible networked devices
• Requires Ethernet cable (not included) for the physical network link

Who is this for: The Sunluway 720074-12 AS EC QDE is intended for anglers, captains, and boat electronics installers who want a compact, reliable way to network Humminbird HELIX displays and compatible accessories. It’s ideal when a short adapter is needed to convert Humminbird connectors to standard Ethernet for clean, serviceable installations aboard small to mid-size boats.
