What are the advantages of can over RS-485?
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.
CAN transceivers will exceed the standard in the same way as RS-485 transceivers. The common-mode range (CMR) is -7V to +12V for RS-485 and -2V to +7V for CAN. Many applications need a wider CMR performance from both of these interface types.

Apr 25, 2022 · CAN Bus VS RS485 - 3 Reasons Why CAN is Better. Updated: May 3, 2022. RS-485 and CAN both happen to be serial communication protocols; they allow multi-drop device arrangement in a single system, considerably cut down cable lengths, are designed to be used in electrically noisy environments, both are terminated using 120 ohms resistance and are ...
Feb 21, 2024 · CAN bus is an asynchronous half-duplex communication protocol, thus the CAN controller has TXD and RXD pins that are used for the transmission and reception of data, respectively. These pins are connected to the CAN transceiver for converting the digital signals to differential signals for the transmission of messages on the bus and vice-versa ...

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.
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.
