As such the terminating resistors form an essential component of the signalling system and are ...

WebCAN bus physical & data link layer (OSI) In more technical terms, the controller area network is described by a data link layer and physical layer. In the case of high speed CAN, ISO 11898-1 describes the data link layer, while ISO 11898-2 describes the physical layer. The role of CAN is often presented in the 7 layer OSI model as per the illustration. WebChoosing the proper bus-termination technique—parallel, series, Thevenin, ac, or diode-based—is critical to digital-system performance. Improper termination can lead to ringing and stair-stepping, which in turn can cause false triggering and data errors.
