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. Weba single 60 ohm termination for lab testing when bus is only a few feet (probably not allowed, but it works). If you don’t have two 120-ohm resistors, you can accomplish the termination (on a small network) with a single 60 ohm resistor (120 in parallel with 120 is 60) or anything close 55-65 is fine.
