STNG SPUR socket protective cap

Blanking Plug – in Estonian simply “blind” or a protective cap, is a necessary accessory to protect the vacant white SPUR (spur cable) sockets of STNG 5-Way connectors. It is advisable to select STNG connectors in such a way that some free SPUR cable sockets always remain available for future use. There should definitely be some free SPUR cable sockets at the captain's table and near control points. These empty “holes” should initially be covered with blanking plugs. The STNG network blind plug is not suitable for the blue socket of an STNG connector because the pin holes do not match, and a correctly built STNG network cannot have any empty blue BackBone sockets. A Raymarine STNG SPUR cable is a spur cable through which devices (blue/black) are connected to the BackBone cable, which, as the name suggests, is the “backbone” cable. The BackBone cable runs through the boat from the beginning to the end of the STNG network, and it is advisable to assemble the network from cables of different lengths so that it is possible to make disconnections and add T-connectors or 5-Way connectors in places where different STNG instruments need to be added. BackBone is the main cable of the STNG network, and to start, continue, or end the network, STNG terminators, connectors, and a 12V power supply must be added. STNG blue and white cables cannot be connected incorrectly; in addition to colour coding, STNG cables also have different pin arrangements. Before using the product, familiarise yourself with the operating principles of the STNG (NMEA2000) network. NB! The blue and white nuts of the STNG connector sockets should only be turned a quarter turn. Corresponding markings are indicated on the product. Be sure to also familiarise yourself with this product with instructions and in case of questions, consult our specialist.
