P-Bus
What is P-Bus?
The philippi on-board bus system: a line with T-pieces to which monitors, shunts, interfaces and switching modules connect as individual nodes. A terminating resistor sits at each end of the line.
What matters about P-Bus in practice?
It uses the waterproof M12 connector system according to DeviceNet, the same as NMEA 2000. The connectors therefore fit there too, but the two networks may only be connected via a bridge.
New nodes are registered and named on the monitor, without a computer and without configuration software. The monitor only shows menus for which data is actually available; if an expected page is missing, the corresponding node is missing.
