CZone NMEA 2000 Network Bridge Interface 80-911-0057-00 for isolating sections of an NMEA 2000 network to decrease standby current draw. Isolation when bridging between two CAN networks, (e.g. 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.
