How do I know if terminating resistors are required?

WebA CAN bus terminator can be used for termination of any high speed (ISO 11898-2) CAN bus system. The 120 Ohm terminating resistor is setup between pin 2 (CAN low) and pin 7 (CAN high). In general, ISO 11898-2 CAN networks must be terminated at each end using 120 Ohm terminal resistors. WebWhy can needs 120 ohm termination resistor? For avoiding reflection we use Transmission Line theory. For the High speed CAN bus the maximum length is 40m, with 1 Mbps speed and maximum of 30 nodes. So here by using 120 ohms resistor as terminating resistor we can avoid all the reflections easily without fail.
