Can bus resistance test

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. WebJun 21, 2024 · And then pins four and five are also ground so you can see we have the ground plugged into pin four on this vehicle. Looking back to the lab scope , how it's set up, you can see both channels are set to 10 volt scale. So that'll give us a nice, good size window. And then we have to set our time base down to 100 microseconds.
