Overview

The Raymarine A80272 is a 400 mm adapter cable that connects a RayNet male plug to a SeaTalk HS male plug for Raymarine marine Ethernet networking. It is a short conversion cable for Raymarine systems where the connector type changes between newer RayNet cabling and legacy SeaTalk HS equipment.

This adapter is commonly used during electronics upgrades or mixed-generation installations, especially when RayNet radar or network cabling needs to interface with compatible Raymarine displays, network hardware, or other SeaTalk HS devices. It carries Ethernet network data only, so it should not be treated as a power cable, NMEA 2000 cable, or general-purpose wiring adapter.

Key features

• RayNet male to SeaTalk HS male adapter for compatible Raymarine network connections.
• 400 mm length, about 15.75 in, for short adapter runs behind a display, at a network switch, or inside an electronics panel.
• Supports Ethernet data used by SeaTalk HS networks, including compatible display, radar, sonar, and shared cartography data.
• Useful for connecting RayNet radar or network cabling to compatible legacy Raymarine SeaTalk HS equipment.
• Purpose-built connector conversion helps avoid improvised cable changes in areas exposed to vibration, service access, and tight routing.

Installation and setup

Before installation, confirm both ends of the connection and the overall network layout. The cable has male connectors on both ends, so it must be matched with the correct RayNet and SeaTalk HS sockets or cable ends in the system.

Route the adapter where it will not be pulled tight when the display, radar cable, or network hardware is serviced. A short strain-relieved run behind the helm, inside a dry electronics cabinet, or near a Raymarine network switch is usually the cleanest approach.

Compatibility and fit

This cable is for Raymarine Ethernet networking using RayNet and SeaTalk HS connector formats. It is a good match for owners and installers working with mixed Raymarine network generations, such as vessels keeping existing SeaTalk HS hardware while adding or adapting RayNet-based cabling.

Check the installation manual for each connected Raymarine device before ordering, especially on older E-Classic, C-Series, E-Series Wide, radar, or network switch installations where crossover requirements and connection paths can affect which adapter belongs in the system.
