Raymarine A06033 SeatalkNG 400MM Backbone Cable

The Raymarine A06033 SeatalkNG 400MM Backbone Cable is the nervous system of modern marine electronics integration, connecting your navigation, sonar, autopilot, and instrument displays into a unified network. Built for serious boaters and commercial operators who demand reliability in harsh saltwater environments, this backbone cable serves as the central data highway for Raymarine's industry-leading SeatalkNG protocol. Whether you're running a fishing vessel, cruising yacht, or workboat, a properly configured network backbone ensures every piece of critical data reaches your helm display without latency or dropout.

The 400MM length provides optimal spacing for multi-unit installations typical of wheelhouse setups, radar pedestals, and distributed sensor arrays found on vessels 30 feet and above. SeatalkNG is a twisted-pair, shielded digital backbone that eliminates the analog signal degradation plaguing older marine networks—your chartplotter receives depth, wind, heading, and GPS data with zero corruption or noise interference. The robust marine-grade construction withstands UV exposure, salt spray, vibration, and temperature cycling, ensuring your network remains stable whether you're running through the Gulf Stream or anchored in tropical heat.

This backbone cable is compatible with all Raymarine SeatalkNG-enabled equipment, including gS and aSeries multifunction displays, wireless handsets, sonar modules, and autopilot computers. Installation requires proper termination at both ends and should follow Raymarine's networking guidelines to maintain full system integrity—improper backbone configuration can create single points of failure across your entire electronics suite. For crews upgrading legacy installations or building new integrated systems, the A06033 is the standard backbone solution recommended by Raymarine dealers and marine electronics installers worldwide.
