A space-saving and particu- larly easy to install system. Several 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 Together with the T-pieces, these cables form the backbone. This may theoretically have a total length of up to 200 meters. These cables also serve as stub cables. Stub cables are the connection between the backbone and an NMEA 2000-compatible device or sensor. A stub ca- ble must not exceed a length of 6 meters. The standard connection cables are each equipped with an M plug (male) and an F socket (female). For special applications, e.g. for the Quick Nautical Network QNN, we also offer cables with F / F connec- tions. 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 so-called backbone, which is formed with T-pieces and connecting cables. Your NMEA 2000-capable devices and a cable for the backbone power supply are connected to the T-pieces of the backbone. 2 3 3) NMEA 2000 T-piece The standard T-piece is equipped with an F female and an Mmale Mic- ro-C connection for the backbone cable and an F female spur connec- tion for connecting devices and sensors. These T-pieces can not only be screwed together using connection cables, but also directly. We also offer T-pieces with other Micro-C connection variants for spe- cial applications. 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 T-piece. Standard cabling requires one F-ter- minal (female) and one M-terminal (male). 6) NMEA 2000 Micro-C elbow 90° This elbow makes it easier to lay cables around sharp edges or to con- nect to devices where there is little space behind them. It is equipped with an F (female) and an M (male) connection. 70 0897 7 5 6 4 Standard cable with F/M connections Special cables with F/F connections LENGTH ORDER NO. NO LENGTH ORDER NO.

A se- parate converter is required for each analog data source whose infor- mation 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®
