CZone connection to NMEA 2000
When interfacing to C-ZONE network it is recommended to use a BEP Network interface
bridge (A) to join the two network backbones together.
The CZONE / NMEA 2000 Network interface bridge isolates the power of the two networks,
but allows data to be freely shared between both sides.
The Network Interface has built in terminators so needs to be placed at the extremity of each
network backbone.
The Interface Bridge can also be used for expansion of the NMEA 2000 network, when the
maximum node limit (node = any device connected to network) for the network has been
reached or the maximum cable length of 150m will be exceeded. Once an Interface Bridge
has been fitted, a further 40 nodes and additional cable length can be added.
The Network Interface is available from your BEP dealer. For more information please refer to
the BEP web site www.bepmarine.com.

Below is the correct method to interface to a C-ZONE network. In this example,
power is injected twice but connecting the two networks together via the BEP
Network interface bridge provides power isolation and correct termination.
