Jul 22, 2021 · The purpose of the termination resistor is to ensure robust current flows throughout the network. The input impedance of CAN or CAN FD transceivers is relatively high (k Ohm’s) and building a robust network means ensuring a strong differential voltage be developed between CANH and CANL.

Jun 19, 2024 · CAN bus is crucial because it simplifies the way machines and vehicles operate. By using a single communication system, it reduces the complexity of wiring and improves reliability. This means fewer problems and easier maintenance. The CAN bus system was developed by Bosch in the mid-1980s.
A controller area network ( CAN) is a vehicle bus standard designed to enable efficient communication primarily between electronic control units (ECUs). Originally developed to reduce the complexity and cost of electrical wiring in automobiles through multiplexing, the CAN bus protocol has since been adopted in various other contexts.
