Controller Area Network (CAN) bus dominates the automotive industry, and, since it’s a robust, error-detecting protocol, it’s also widely used in automation and control environments, ships, locomotives and medical equipment. A twisted pair multidrop cable is specified with a length ranging from 1,000m at 40Kbps to 40m at 1Mbps. All nodes on the network receive each message and then decide whether that identifier value is of interest.

Here you’ll find a compact series of CANcontrollerBOXes, intelligent CAN-USB converters, and CANlook software from Janz; CANstick – a CANbus OBD datalogger from IHR; and CANxtra a .Net development box with built-in CANbus port.
