May 10, 2017 · When comparing the physical layer only, CAN and RS-485 are similar in that they both use differential signaling. This gives them both good common mode noise immunity. The main difference is that RS-485 uses symmetric signaling. One line is 5 V and the other 0 V to signal one state, then flipped to 0 V and 5 V for the other state.
Jan 18, 2024 · CAN bus can be a preferable option if you require a real-time, high-speed communication protocol for an automotive or robotics application. RS485 can be a preferable option if you require a strong and dependable protocol for building automation or industrial automation.
Apr 25, 2022 · Though RS-485 port is still added to many new-age technologies, CAN feature such as arbitration, error-message checking, improved bandwidth, and a larger data field have accelerated the demand for CAN bus, even in the industrial market.
