Nov 6, 2023 · A 2-wire CAN bus harness is a multi-master serial bus that interconnects electronic control units in a vehicle, meaning the CAN bus network must have at least two controllers. This node or controller can be as simple as a programmable logic device and field-programmable gate array or as complex as an embedded computer with sophisticated software. So the two farthest end nodes in the network can drive TERM=High to enable termination of 120 ohm across the bus, while all other nodes can drive TERM=Low. This way the CAN bus effective termination is 60 ohm (120 ohm on both ends in parallel); while the hardware design of each node can be the same. Node 1. Node 2.CAN bus protocol which is also known as control area network protocol is a half-duplex high-speed serial network technology developed by Bosch in the 80’s.
