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 and should be sized to run past every location where an NG or NMEA 2000 device might be installed. Raymarine SeaTalk-Ng Backbone Cable A06033 (0.4m / 400mm, beige) is a plastic cable assembly designed for marine NMEA 2000/SeaTalk ng networks. Two backbone cable lengths can be joined together by part A06030, a backbone extender. Package quantity: 1. Item Dimensions (L x W x H): 1.97 x 1.57 x 0.39 inches.
