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.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
