      • RS485 employs point-to-point communication, whereas CAN uses bus-based communication. While RS485 can accommodate more nodes on a single communication connection and operate over longer distances than CAN, CAN offers superior speed and bandwidth.

  2. May 10, 2017 · The main difference is the bus arbitration of CAN, which means that the network topology is flexible and there is no need for a master to control traffic. In RS-485 there is no built-in mechanism to toggle who gets to send, meaning that RS-485 tends to end up in a star network topology centred around a master.

  3. Even though the new CAN-FD standard, ISO 11898- 2:2016, defines certain timing characteristics at 2Mbps and 5Mbps, the standard does not cap the data rate at 5Mbps. CAN transceivers will exceed the standard in the same way as RS-485 transceivers.

  4. Apr 25, 2022 · Just like RS-485, the signal through CAN flows on CAN high and CAN low as differential voltages. This may sound similar to RS-485, but that is not true. The features that have helped CAN become a real-time compatible solution are:

  5. Oct 4, 2022 · Oct 4 2022. Join Dave and Bob as they explore the similarities and differences between two key serial interface protocols, Controller Area Network (CAN) and RS-485. See both protocols on oscilloscopes using one of our RS-485 interface transceivers and our latest CAN transceiver.

  6. CAN (Controller Area Network) and RS485 are both popular standards in fieldbus systems. RS485 only addresses layer 1 (the physical layer) CAN also adds layer 2 (the data link layer) in the OSI model. Both are based on multiple nodes connected to a shared serial bus with one or more acting as a master being possible.

    Jan 18, 2024 · Autonomous Vehicle Technology. INTRODUCTION. Communication protocols are essential for establishing connections between devices and for effective data interchange in industrial and automation applications. The Recommended Standard 485 (RS485) and the Controller Area Network (CAN) are two of the most widely used protocols in this industry.
