NMEA 2000 Network Kit (with A2K-TDC-2m cable) QNB-1 Solution – Very High Device Density – 27 Devices Ideal for large and very large vessels, fully customizable, can be connected to mid-size backbone cableĪ2K-RSK-1 Solution – Low Device Density – 6 DevicesĪ2K-KIT Solution – High Device Density – 15 Devices Ideal for small, medium and large vessels, fully customizable Ideal for small boats, with initially 3 NMEA 2000 Devices, expandable to max 10-25 NMEA Devices* Limited customization Ideal for very small boats with maximum 4 NMEA 2000 Devices, not customizable Mid-fed, with 2 x 3VDC, one for each backbone segment. Sample diagrams are included hereafter.Įnd-fed, self-contained backbone with terminators and 4-way T-Piece.Įnd-fed or mid-fed but with only 1 x 3VDC power for both backbone segments. All, except the A2K-SBN, can be customized and expanded. To design your NMEA 2000 Network, Actisense offers 4 types of solutions based upon 4 different types of backbone Power-Insertion Components. NMEA 2000 Convertors – To convert NMEA 2000 to NMEA 0183 and vice versa or to USB or RS232/422.

This is an older standard, but is still widely used, especially on commercial IMO SOLAS vessels.Īs is immediately obvious from above diagrams, NMEA 0183 uses significantly more cabling to connect all devices. Older Marine Electronic Devices commonly have NMEA 0183 interfaces. Mid-Feed=2 backbone segments totally 100m Maximum Voltage Drop per Backbone recommended for higher backbone lengths and/or high LEN Maximum Number of NMEA 2000 Devices per NetworkĮquivalent Network Load for all devices (LEN) per Backbone Segment In addition, NMEA 2000 networks should be designed adhering to below rules. All the required NMEA 2000 network parts can be supplied by Actisense via Lambda Marine.īackbone maximum cable length (terminator-to-terminator) Additional cable lengths can be used between any of the connectors to extend the length of the network, whilst ensuring that the NMEA 2000 rules for cable lengths are adhered to, see below “Table 1 - NMEA 2000 Cable Length Rules”. T-Pieces are needed to connect each device to the network. 2 x NMEA 2000 Devices (such as the Actisense EMU-1 and/or any other NMEA 2000 certified device from various manufacturers such as Radars, Chartplotters, GPS etc.).2 x T-Pieces (one per connected device).2 x Terminating Resistors (to terminate the network on both ends of the backbone).1 x Power-T (to insert network power, should be fused).In addition, a correctly functioning network will require at the minimum the following components:
