Block circuit diagram of CAN-PC104/200
The CAN-PC104/200 board is a CAN-module for the PC/104-bus (PC/104, 8 bit). It uses a
SJA1000 CAN controller. The module can be operated in FULL- or BASIC-CAN.
The CAN-interface is ISO11898-compliant and allows a maximum data-transfer rate of 1 Mbit/s.
The bit rate, like many other properties of the CAN-interfaces, can be set by means of software.
The CAN-interface is electrically insulated from other potentials by means of optocouplers and
DC/DC-converters.
