Raymarine SeaTalk NG Backbone Cable, NMEA 2000, 5-Pin to 5-Pin

Overview

The Raymarine SeaTalk NG Backbone Cable is the main trunk cable used to build or extend a Raymarine SeaTalkNG network on board. It runs through the vessel and carries both data and power between connected sensors, instruments, displays and network accessories.

This range covers common backbone run lengths from short 400 mm links through to a 20 m cable, so it can be used for compact helm installations, longer cable runs through a cabin or console, or extended layouts on larger boats. The cable connects to the blue backbone terminals on SeaTalkNG T-connectors, 5-way connectors and compatible Raymarine network devices.

Key features

• SeaTalkNG backbone cable for creating or extending the powered data trunk in a Raymarine marine electronics network.
• Carries both network data and power along the backbone, with individual devices connected by SeaTalkNG spur cables.
• Available in 400 mm, 1 m, 3 m, 5 m, 9 m and 20 m lengths to suit different helm, cabin, cockpit and equipment-space layouts.
• Connects to the blue backbone ports on SeaTalkNG T-pieces, 5-way connectors and other compatible network hardware.
• Supports cleaner cable routing by letting the backbone pass close to the locations where instruments, sensors or displays will be added.

Variants

The available configurations vary by cable length: 400 mm, 1 m, 3 m, 5 m, 9 m and 20 m. This lets the same SeaTalkNG backbone cable type be matched to short interconnects behind a helm panel or longer runs through the boat.

Across the range, the connection role remains the same: each cable is used as part of the SeaTalkNG backbone and plugs into the blue backbone side of compatible SeaTalkNG network fittings.

Installation and setup

Plan the backbone route before installation so it runs past the main locations where networked equipment may be installed. Displays, sensors and instruments normally connect to the backbone through spur cables and T-pieces, while the backbone itself forms the main path for network communication and power distribution.

For longer or more complex layouts, cable length should be selected to avoid unnecessary loops while still leaving enough service slack for access behind panels and at connection points. SeaTalkNG backbone cables can also be joined with the correct backbone extender when a custom run length is needed.

Compatibility and fit

This cable is for Raymarine SeaTalkNG network installations and is not a general-purpose power cable. It is a good match for boat owners, installers and electronics technicians adding Raymarine instruments, sensors, autopilot components or multifunction displays to an existing SeaTalkNG backbone.

Before ordering, confirm the required cable length, the location of the blue backbone ports, and the overall network layout, including terminators, power feed and spur connections. Matching the cable to the actual run on the boat helps keep the installation tidy and easier to service later.

Shipping

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
