1.1 Description of the CAN-PCI104/200
Figure 1:
Block circuit diagram of the CAN-PCI104/200
The CAN-PCI104/200-board offers one or two CAN interfaces for the PCI-104 bus or PC/104-Plus
bus. Up to 4 CAN-PCI104/200-modules can be operated in a stack. Thus up to 8 CAN interfaces
are available.
The module can be operated in PCI-104 systems with 3.3 V or 5 V signalling voltage.
The ISO 11898-2- compliant CAN interface allows a maximum data transfer rate of 1 Mbit/s.
Among other properties of the interface the bit rate can be parameterized by software.
The CAN-interface is electrically isolated by a magnetic high speed data coupler and a DC/DC-
converter.
Software drivers for many operating systems as Windows and Linux are available. Real-time
operating systems as for example QNX are supported as well.
