WebThe terminating resistor must have two on the CAN bus, the resistance is 120 ohms, parallel, and one end of the farthest end. No more, no less. If you are not sure, use a multimeter to measure. The best between 60 Ω and CAN-H between CAN-H and CAN-L. If there are multiple nodes, the terminating resistor should be appropriately increased. WebTermination is used for two reasons. First is to improve signal quality. Termination prevents reflections that might cause communication failure as a result of ringing (oscillation) on the bit edges. Reflexions can be particularly strong when the signal reaches the end of the cable, which is why termination adapters are placed at the ends.
