Description
Backbone Cables In a SeaTalk ng installation, a backbone cable runs through the length of the boat. Individual devices connect to the backbone by spur cables that run to T-pieces on the backbone.
The backbone carries both data and power to attached devices. The backbone should be sized so that it will run past every location where an NG or NMEA 2000 device might be installed.
Two backbone cable lengths can be joined together by part A06030, a backbone extender.

Marine Navigation & Instruments — frequently asked
- What’s the difference between a chartplotter and a fishfinder?
- A chartplotter shows your GPS position on electronic charts for navigation. A fishfinder uses sonar to show what’s below the boat — depth, bottom structure, and fish. Many modern units combine both, and networked systems can share data across displays.
- Do I really need a VHF radio?
- For safety, yes. A VHF radio is the primary way to reach other vessels and the Coast Guard, and a DSC-equipped VHF connected to GPS can transmit your position in an emergency. It’s more reliable than a cell phone offshore and is the recognized standard for marine distress calls.
- What is NMEA 2000 and do I need it?
- NMEA 2000 is a standard network that lets marine electronics — chartplotter, sonar, autopilot, sensors, engine data — share information over a single backbone. It’s not required for a simple setup, but it makes multi-device systems far easier to expand and integrate.
