Figure  1:

 Block circuit diagram of the CAN-PCI/405-B4

The CAN-PCI/405-B4 is a PC board designed for the PCI bus. It supports four independent CAN
interfaces. The four CAN interfaces can be connected via the 37-pole DSUB panel connector in the
slot bracket.

The CAN-PCI/405-B4 provides four ISO 11898-compliant CAN interfaces based on SJA1000 CAN
controllers. The CAN interfaces allow a data transfer rate of 1 Mbit/s. 
The baud rate can be set by per software. 
The interfaces are electrically isolated from the other potentials.

The  CAN-PCI/405-B4  produces hardware-generated timestamps with a resolution of 1 μs for all
CAN messages. A PowerPC

TM

 405GP cares for the local data management of the CAN-PCI/405-

B4. 

The CAN data are buffered in a local SDRAM. Security and consistency of data is guaranteed up
to 1 Mbit/s.
