Planning and installing a network backbone
The backbone needs to run between the locations of all products to
be installed - typically in a bow to stern layout - and be no further
than 6 m from a device to be connected.
Choose from the following components to make up the backbone:
•
Micro-C cables: 0.6 m (2 ft), 1.8 m (6 ft), 4.5 m (15 ft), and 7.6 m (25
ft) cables.
•
T-connector or 4-way connector. Used to connect a drop cable
to the backbone.
•
Micro-C power cable. Connect to the backbone at a position that
is central to the network load using a T-connector or 4-way
connector.
Power the network
The network requires its own 12 V DC power supply protected by a
3 amp fuse or breaker.
Connect power at any location in the backbone for smaller systems.
For larger systems introduce power at a central point in the
backbone to
balance
the voltage drop of the network.
Ú
Note:
If joining to an existing NMEA 2000 network that already
has its own power supply, do not make another power
connection elsewhere in the network, and ensure the existing
network is not powered by 24 V DC.
Ú
Note:
Do not connect the NMEA 2000 power cable to the same
terminals as the engine start batteries, autopilot computer, bow
thruster or other high current devices.
The following drawing demonstrates a typical small network. The
backbone is made up of directly interconnected T-connectors.
