Choice of Hardware Designs
The CPCI-CAN/402-4 is a CompactPCI board designed for the PCI bus that features four electrically isolated high-speed CAN interfaces according to ISO 11898-2.
The DSUB25 CAN connector is located in the front panel. As successor of the CPCI-CAN/402-4 board the CPCI-CAN/402-4-FD comes with four CAN FD interfaces.
CAN Data Management
The independent CAN nets according to ISO 11898-1 are driven by the esdACC (esd Advanced CAN Core) implemented in the Altera FPGA. The FPGA supports Bus Mastering (first-party DMA) to transfer data to the host memory. This results in a reduction of overall latency on servicing I/O transactions in particular at higher data rates and a reduced host CPU load.
Due to the usage of MSI (Message Signaled Interrupts) the CPCI-CAN/402-4(-FD) can be operated for example in Hypervisor environments.
The CPCI-CAN/402-4(-FD) provides 64-bit hardware timestamp with bit time accuracy.
Software Support
Windows and Linux (NTCAN-API)
The CAN layer 2 drivers for Windows and Linux are included in the scope of delivery of CPCI-CAN/402-4 (I.2332.08).
Realtime OS (NTCAN-API)
CAN layer 2 drivers for QNX, RTX(64), VxWorks and On Time RTOS-32 can be ordered separately.
Higher Layer Protocols
(Classical CAN application only)
Higher Layer Protocols for Classical CAN applications are available for many operating systems (see order info):
CANopen Master- and Slave-Stack
J1939
ARINC825
Additional free-of-charge esd CAN tools for Windows are downloadable from our website. The tools offer efficient setup and analysis of Classical CAN applications and networks.
Customization on Request
Customized options are available for customized series production in reasonable quantities. Please contact our sales team for detailed information.
CPCI-CAN/402-4 Successor with CAN FD
The CPCI-CAN/402-4 (I.2332.08) is not recommended for new designs. (It can still be used in existing systems, e.g. if the drivers shall not be reinstalled.)
Use the successor CPCI-CAN/402-4-FD for new projects. It comes with a more powerful FPGA and supports CAN FD.
Furthermore, it can also be used in Classical CAN applications, because it is fully backwards compatible with CAN.Drivers and software support for other operating systems are available on request.Check attachment for Software Support
