A space-saving and particularly easy-to-install system. Multiple navigation, communication, or mo- nitoring instruments can be connected to a network and read via a central display. 1) NMEA 2000 connection cable with Micro-C connectors These cables, together with the T-pieces, form the backbone. In theory, this can have a total length of up to 200 meters. These cables also serve as drop cables. Drop cables are the connection between the backbone and an NMEA 2000-compatible device or sensor. A drop cable must not exceed a length of 6 meters. The standard connection cables are equipped with an M plug (male) and an F socket (female). For special applications, e.g. for the Quick Nautical Network QNN, we also stock cables with F/F connections. 2) NMEA 2000 power cable The backbone of an NMEA 2000 network requires its own 12-volt pow- er supply. This cable is equipped with a Micro-C M (male) connector. The other end of the cable is bare. We recommend protecting the posi- tive line with a 3A fuse. NMEA 2000® The main component of the NMEA 2000 network is the backbone, which is formed using T-pieces and connecting cables. Your NMEA 2000-compatible devices are connected to the T-pieces of the back- bone, as is a cable for supplying power to the backbone. 2 3 3) NMEA 2000 T-piece The standard T-piece is equipped with a female F and a male M micro- C connector for the backbone cable and a female F stub connector for connecting devices and sensors. These T-pieces can be screwed toge- ther directly, as well as using connecting cables. For special applications, we also offer T-pieces with other Micro-C con- nection variants. 4/5) NMEA 2000 Micro-C end terminals for backbone These end terminals are essential for a functioning NMEA 2000 net- work and must be connected at both ends of the backbone, regardless of whether it is a cable or a T-piece. With standard cabling, one F-ter- minal (female) and one M-terminal (male) are required. 6) NMEA 2000 Micro-C 90° angle piece This angle piece makes it easier to lay cables around sharp edges or connect to devices where there is little space behind them. It is equip- ped with an F (female) and an M (male) connection. 70 0897 7 5 6 4 Standard cable with F/M connectors Special cable with F/F connectors LENGTH ORDER NO.

A separate converter is required for each analog data source whose in- formation is to be fed into an NMEA 2000 network. It is equipped with an NMEA 2000 standard connector and a 2-pin cable for the analog signal line and ground. 70 0190 57 NMEA 2000®
