WebA driver on the bus can also be in a third state, with the driver outputs in a high impedance state. If all nodes are in this condition , the bus is in an idle state. In this condition, both bus lines are usually at a similar voltage with a small differential. Signaling for CAN differs in that there are only two bus voltage

WebCAN Bus Termination Resistor: A component used in a Controller Area Network (CAN) to prevent signal reflections and ensure proper signal transmission. CAN Bus Termination Resistor Value: The resistance value of the termination resistor that matches the characteristic impedance of the CAN bus. WebThe basic rule when choosing a termination resistor is that the value of the resistor must equal the characteristic impedanceof the twisted pair cable. Termination resistor prevents signal rebound, like waves hitting a wall. The characteristic impedance of twisted pair cables is not a magic number.
