Two Channel CAN PCI-104 Interface Card

The CAN-PCI-104-02 is a dual channel CAN interface card for the PCI-104 bus. Galvanic isolation provides better noise immunity in industrial environments.

The card incorporates a high performance 32-bit RISC processor. This processor handles all low level details of interfacing with the CAN hardware, offloading this task from the host processor. A 4 Kbyte dual-port RAM is used to buffer messages to and from the host processor.

The on-board processor synchronizes its local clock to the host processor clock. All received messages are time stamped using this clock with 1 microsecond accuracy. Transmitted messages may also be time stamped with their actual transmit time. This allows for simple implementation of the CANopen network synchronization protocol (DS-301 object 0x1013).
