1.1.1.3.2. High-Speed CAN (125 kBit/s , 500 kBit/s)

General CAN fundamentals

High-Speed CAN (125 kBit/s , 500 kBit/s)

- 125 kBit/s : Interior CAN busSeries 221

- 125 kBit/s : Telematic CAN busSeries 221

- 500 kBit/s : For example:Drive train CAN bus

- 500 kBit/s : For example:Diagnostic CAN-Bus

- This CAN bus does not permit single-wire mode.

- This means that both CAN lines are always required for fault-free communication between the control units.

- This CAN bus requires external terminating resistors.

- The terminating resistors can be located in control units or voltage distributors depending on the CAN bus.
