CAN Bus Description

The Controller Area Network (CAN) specification defines the Data Link Layer, ISO 11898 defines the Physical Layer. The CAN bus is a Balanced (differential) 2-wire interface running over either a Shielded Twisted Pair (STP), Un-shielded Twisted Pair (UTP), or Ribbon cable. The pinouts on this page are associated with the CANopen protocol. For additional information refer to the main CAN Bus page.
CANbus is used as a vehicle bus, for other vehicle Buses see the Automotive Bus page {This Site}.
CANbus is also used as an Industrial Field bus, for other Field Buses see the Field Buses page {This Site}
