Marine Ethernet Switch for Humminbird Units

The GSM Outdoors 408450-1 is a waterproof five-port Ethernet switch built for Humminbird fish-finder and chartplotter networks. It connects up to five Ethernet devices so multiple head units can share sonar, mapping and radar data across a single integrated system. The unit is designed for marine environments where reliable wired networking is required.

Installation Requirements and Network Expansion

Compatibility spans HELIX 8, 9, 10, 12 and 15 models plus select HELIX 7 G4N, G3N and G2N variants, along with legacy 778, 788, 798, 858, 859, 898, 899, 958, 959, 998, 999, 1157, 1158, 1159, 1197, 1198 and 1199 series units. HELIX models need an AS EC QDE adapter cable plus an Ethernet cable, while APEX, SOLIX, ONIX and ION models connect directly with an Ethernet cable. The switch frees installers from daisy-chain limits and lets each device talk to every other on the network.

Sustained Operation in Wet Conditions

The waterproof housing protects the switching electronics from spray, rain and temporary immersion during extended days on the water. Passive cooling keeps the five ports running continuously without fan noise or moving parts that could fail. The sealed design maintains link stability when the boat is underway, so shared waypoints, sonar returns and radar overlays stay consistent across all connected displays. Buyers needing wireless connectivity or non-Humminbird protocols should look elsewhere.

Questions about this item

How many devices can the 5-port switch connect before bandwidth becomes the bottleneck?

The switch provides five Ethernet ports, so up to five devices share the available bandwidth; sustained throughput will be limited by the slowest link in the chain.

Does the waterproof housing stay cool and quiet when the switch runs continuously on a boat?

The sealed, fanless design relies on passive cooling, so it operates silently and without measurable heat buildup during all-day use.

Which adapter cable is required to install the switch on a Helix 7 G4N unit?

An AS EC QDE adapter cable plus a standard Ethernet cable are needed for Helix 7 G4N models; Apex, Solix, Onix and Ion units only need the Ethernet cable.
