It is very urgent.

Thanks

The pinout can be found on page 4-1 of the NI-CAN Hardware and Software Manual that is installed with the NI-CAN driver at Start >> Programs >> National Instruments >> NI-CAN.  I'm not sure what you mean by the "Block Diagram" but the manual has various diagrams of the board, bus, trigger lines, switches, etc.  What information do you need?

Unfortunately that information is unavailable.  All the information we have released along those lines is included in the manual.

Why do you need this information? If there is something in particular you are looking for, it may be answerable.

Hi Raman,

In general, the CAN controller gets a message from the CAN transceiver, which is put into an output buffer. Then an IRQ line is set to signal the CPU that a new CAN message is available. I've also provided some information about CAN that you should find useful.
