FAQ

 

Q: Why are terminating resistors needed on CAN bus?

 

A: Terminating resistors are used on a CAN bus to ensure that signal reflections are minimized and that the bus operates at maximum efficiency. They are placed at the two ends of the bus to absorb any signal reflections that occur when the signal travels to each end of the bus. This optimizes the signal quality, reduces interference and improves communication. Without terminating resistors, the efficacy of the bus can decrease, leading to communication errors or even loss of data. Therefore, using terminating resistors is essential to maintain a stable and reliable CAN bus.
