CAN bus termination at both ends of the bus is necessary to remove any electrical reflections on the bus and to guarantee the correct DC levels. Web27 aug. 2024 · CAN nodes listen to the bus and will only attempt to transmit frames if the bus is idle. As soon as the bus becomes idle, however, multiple nodes may attempt transmission simultaneously. Since dominant (0) wins out over recessive (1) on the CAN bus, an individual node can check to see if its recessive bits are, indeed, recessive.
