CAN bus
What is CAN bus?
The underlying transmission method on which many bus systems are built: two twisted wires, all nodes with equal rights on one line, messages with a priority identifier.
What matters about CAN bus in practice?
P-Bus and NMEA 2000 both use CAN as their physical basis, but different message formats. Same technology therefore does not mean same language; coupling them requires translation.
The CAN basis also determines the installation rules: one continuous line, short drop cables, a terminating resistor at each end. Follow these three points and you will never have half of all bus problems.
