Block circuit diagram of CAN-PCI/200
The CAN-PCI/200 is a PC board designed for the PCI bus. It is available with one or optional two
CAN interfaces.
The ISO 11898 compliant CAN interfaces allow a data transfer rate of 1 Mbit/s. Among many other
features, the bit rate can be set by software. The CAN interface is electrically isolated from the
other potentials by optocouplers and DC/DC-converters.
