Low-Speed CAN (83,3 kBit/s)
- 83,3 kBit/s : For example:Interior CAN busSeries 211
- This CAN bus enables single-wire mode.
- 'Single-wire mode' means that fault-free communication between the control units is still possible even if one of the two CAN lines fails.
- This CAN bus does not require external terminating resistors.

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.
