NMEA2000 Connector (CAN bus connector)
CAN bus is a communication protocol that shares multiple data and signals through
a single backbone cable. You can simply connect any CAN bus devices onto the
backbone cable to expand your network onboard. With CAN bus, IDs are assigned
to all the devices in the network, and the status of each sensor in the network can
be detected. All the CAN bus devices can be incorporated into the NMEA2000
network.
