: CZone NMEA 2000 Network Bridge Interface Module (8-94246)

For isolating sections of an NMEA 2000 network to decrease standby current draw
Isolation when bridging between two CAN networks, (eg connecting CZone to Simrad Simnet)
For expansion of the NMEA 2000 network when the maximum node limit (node = any device connected to the NMEA 2000 network) for the network has been reached
Once fitted, a further 40 nodes can be added

Allows one bus to be powered off while the other remains operational, (power saving i.e. drop out electronics over night but keep CZone bus running)
Allows two different power supplies to be used, i.e. CZone network run from Domestic batteries while connected to an Engine monitoring network which derives power from Engine battery supply
Can be used to assist with voltage drop issues on long networks i.e. install NBI in centre of bus and connect power supplies either side (at midpoint of each network)

Allows NMEA 2000 and proprietary messages to pass between two independent CAN networks
Filters and stops any corrupt NMEA messages from passing from one network to the other
Can be used to expand a network when the node limit maximum has been reached (a node is a device connected to and operating on the NMEA 2000 network) – When the 40 node limit has been reached (or bus load is too great) a NBI can be fi tted to allow a further 40 nodes to be added to the network
Should one bus “lock up” the NBI will prevent the second bus from becoming corrupted ie protects mission critical control network from becoming corrupted by any faults on the secondary monitoring network
LED repeater on case for network status reporting
