Term Definition
CAN CAN is an acronym for Controller Area Network.
Standardized by ISO as a serial communications protocol,
CAN was developed by the German electrical equipment
manufacturer, BOSCH, for use in automotive networks.
After being regulated by ISO, CAN soon became the
de-facto standard in the automobile industry.
CAN technology is now used in various other fields such as
factory automation, agriculture, medical equipment, nautical
craft, and also DeviceNet.
ISO11898-2 The high-speed CAN communications standard. The bit rate
range is between 125 kbps and 1 Mbps. It may not be
connected to a fault-tolerant CAN bus.
Terminating resistor The resistor used in order to minimize reflection of an
electric signal, also called a terminator.
Dominant A logical 0 is represented by the dominant bit. When a
dominant bit and a recessive bit are output simultaneously
by two different drivers on the same bus, only the dominant
bit is observed on the bus signal line.
Recessive A logical 1 is represented by the recessive bit. When the bus
is in the idle state, a recessive bit is observed on the bus
signal line.
