Can a spur cable be used to join two SeaTalkng 5-Way Connectors?
It is not permissible to join two SeaTalkng 5-Way Connectors to one another via a SeaTalkng Spur Cable. As part of a powered and properly terminated SeaTalkng / NMEA 2000 backbone, SeaTalkng 5-Way Connectors, T-Pieces, Inline Terminators, SeaTalk to SeaTalkng Converters, and iTC-5 Analog Instrument Transducer Converters must be interfaced to one another via appropriate lengths of SeaTalkng Backbone Cable. The backbone should be powered from a single spur which located at the approximate midpoint of the backbone's LEN load. It is considered to be a best practice that the backbone be powered using a SeaTalkng Power Cable (rather than an autopilot ACU or course computer) which in turn has been connected to a switched and preferably dedicated 12 VDC power circuit.
