Ú
Note: Most SimNet devices can be connected to a NMEA 2000 backbone by using
adapter cables.
Ú
Note: Units with two NMEA 2000 sockets can either be connected inline with the
backbone, or wired individually off a drop cable. Connecting from device to device is
known as daisy chaining. This network topology is not officially NMEA 2000 compliant.
Powering the network
The network requires its own 12 V DC power supply, protected by a 3 amp fuse.
For smaller systems: connect power at any location in the backbone.
For larger systems: connect power at a central point in the backbone to balance the voltage
drop of the network. Make the installation such that the load/current draw on each side of
the power node is equal.
Ú
Note: 1 LEN (Load Equivalency Number) equals 50 mA current draw.
