When interfacing to C-ZONE or another NMEA2000 network it is recommended to use a
BEP Network interface bridge (A) to join the two network backbones together.
C-ZONE / NMEA2000 Network interface bridge isolates the power of the two networks
but allows data to be freely shared between.
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 SimNet network, when the
maximum node limit (node = any device connected to the SimNet network) for the
network has been reached. Once a Interface Bridge has been fi tted, a further 40 nodes
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 another NMEA2000 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
