NMEA2000 Heavy Cable installation or combined
heavy and light cables
If the network complexity (large system) requires the use of
heavy NMEA2000 cables, we recommend that you consult a
skilled technician for advice on how to get a proper network
layout and installation.
3.4 Performing the installation
Finding the SimNet connector(s) on the
product
The SimNet connector is easily recognizable on a product by its
yellow color.
Connect the yellow face cable plug to a yellow connector. In a
small or medium system the red face power cable plug must be
plugged into a yellow connector at either of the two end points
of the network.
A plug with a red face has a built in termination and is only used
in a small or medium system.
Note ! The first production lots of SimNet T-joiners were made with
black connectors. They can be used without problems in a
SimNet system with yellow plugs and connectors.
Network cable installation
Before beginning the installation make sure you have purchased
all the necessary standard cables and accessories to complete the
installation.
The SimNet bus is well protected against electrical interference,
however, it is always good practice to run data cables separate
from power cables (110/240V mains and 12/24V battery).
Pay special attention to power cables supplying high current for
electrical motors (hydraulic pumps), electronic fuel injection,
thrusters, refrigerators, echo sounders, radars, etc.
The light weight SimNet cable and plug system is well protected
against vibrations, but it is recommended to secure long cables,
not more than 50 cm (20”) from the SimNet connector.
