NMEA 2000 páteřní/odbočovací kabel (4 m)

The NMEA 2000 standard is a "plug-and-play" communication standard used to connect marine sensors and displays within vessels. It is considered the successor to the NMEA 0183 serial data bus standard and enables high-speed data transfer, reaching 250 kilobits per second.

This cable is an essential component for establishing and extending an NMEA 2000 network on board. Due to its versatility, it can be used either as a backbone cable to extend the main network or as a drop cable to connect individual devices to the network.

This specific cable has a length of 4 meters (about 13 feet).

Yes, a NMEA 2000 cable up to 6 meters (20 feet) long, such as this 4-meter cable, can be used interchangeably as a backbone cable or as a drop cable.

The maximum allowed length for an NMEA 2000 drop cable is 6 meters (20 feet).

Yes, this cable is compatible with a wide range of Garmin devices certified for NMEA 2000, such as AIS transponders and various modules (GBT 10, GFL 10, GFS 10). It is also compatible with other NMEA 2000-certified equipment, as it complies with the universal communication standard.

This cable is fitted with NMEA 2000 micro connectors. These connectors are compatible with the Garmin ecosystem and other NMEA 2000-certified cables and devices.

This cable handles both data transmission and power supply for devices connected to the NMEA 2000 network, simplifying the overall system wiring.

The NMEA 2000 network, using this type of cable, enables high-speed data transfer, reaching up to 250 kilobits per second, which is critical for the responsiveness of navigation systems and sensors.

To connect a device to the NMEA 2000 network using this cable as a drop, you must plug it into the top of a T-connector. The T-connector is then integrated into the network backbone.

To extend the NMEA 2000 backbone with this cable, you must connect it using two T-connectors on each side. The backbone must always be built in a linear configuration.

The NMEA 2000 backbone must be built in a linear fashion, connecting T-connectors directly or via backbone cables like this one. It must be terminated at both ends with 120-ohm resistors.

The NMEA 2000 network requires a nominal 12 Vdc power supply. NMEA 2000 devices must operate between 9 and 16 Vdc. It is critical not to connect the network to a voltage source exceeding 12 Vdc to avoid damaging the components.

The dedicated NMEA 2000 power cable must always connect to the top of a T-connector, not the sides. It is recommended to connect it via an auxiliary switch to prevent discharging the boat's battery.

Yes, terminators (120-ohm resistors) are absolutely necessary. They must be installed at both ends of the NMEA 2000 backbone to ensure signal integrity across the entire network.

If a device is already supplying power to the NMEA 2000 network and you want to avoid having two power sources on the network, you can install this device using a NMEA 2000 power isolator (Garmin part number 010-11580-00).

It is recommended to start with a detailed network diagram, including all devices to be connected, their approximate location, distances between them and the backbone, as well as the electrical load (LEN) of each device. This allows you to adjust the plan according to NMEA 2000 construction principles.

The technical document only mentions compatibility with NMEA 2000 micro connectors. There is no information about adapters to other types of NMEA connectors (such as NMEA 0183) or other standards. This cable is specifically designed for the NMEA 2000 network.

The "LEN" (Load Equivalency Number) is a simplified value representing the amount of current a device draws from the NMEA 2000 network. A LEN of 1 equals 50 mA. This value is critical for calculating power requirements and balancing the NMEA 2000 network.

Yes, it is possible to shorten this cable if a custom length is required. Garmin offers field-installable connectors (part numbers 010-11094-00 for male and 010-11095-00 for female) that can be used to create or modify the length of NMEA 2000 backbone or drop cables.
