Overview

The Raymarine A06031 is a SeaTalkNG backbone terminator used to close each physical end of a SeaTalkNG backbone. Two terminators are required in every system, and they help keep network traffic stable by reducing reflections and interference on the data line.

On a boat with Raymarine displays, instruments, autopilot components, or sensors sharing the same SeaTalkNG backbone, this is one of the small parts that lets the network operate as intended. It belongs on the backbone itself, not on spur connections, so it is worth checking the network layout before installation or when replacing missing pieces in an existing system.

Key features

• Used at the two physical ends of a SeaTalkNG backbone
• Two terminators are required for a complete SeaTalkNG system
• Helps maintain signal quality across the network by limiting interference and reflections
• Supports SeaTalkNG installations used to carry NMEA 2000 data between compatible onboard electronics
• Different from a spur blanking plug and different from an inline terminator used at a device connection point

Compatibility and fit

This terminator is for Raymarine SeaTalkNG backbone connections. It is the correct part when you are finishing the main backbone run at both ends. It is not the right part for an unused spur port on a T-piece or 5-way connector, and it is not the same part used when a device is connected directly at the end of the backbone.

Installation and setup

During network setup, fit one terminator at each end of the overall backbone after the power connection, backbone cables, and spur drops are in place. A SeaTalkNG network that is not terminated correctly can have communication issues, which makes this part important even though it is small and easy to overlook.

Use on board

This is a practical replacement part for boats already running SeaTalkNG, and it is just as relevant when building a new network around Raymarine instruments, autopilot components, sensors, or multifunction displays. It suits refits, service work, and new installations where clean network communication matters as much as the main electronics themselves.
