The Raymarine E55040 is a 3‑pin female HSB/HSB2 Y‑cable splitter designed for use with Raymarine Pathfinder network devices, such as multifunction displays, autopilots, and other marine instruments. It allows multiple devices to share the same HSB (High-Speed Bus) or HSB2 network, enabling data communication between instruments on the same marine network.
This Y‑cable features one male connector input and two female connector outputs, effectively splitting a single HSB/HSB2 bus line into two. It is commonly used in marine electronics systems where multiple displays, sensors, or autopilot controllers need to be connected to the same bus without requiring a network hub.
The cable is rugged and marine‑grade, designed to withstand the harsh conditions of a vessel’s bridge or cockpit environment. Its compact design allows easy installation in tight spaces behind panels or navigation consoles.
