Product Description

Wide Choice of Hardware Designs

The CAN-PCIe/**2 is a PC board designed for the PCIe bus that features one, two (CANPCIe/****2) or four (CAN-PCIe/****4/2Slot) electrically isolated CAN High-Speed interfaces according to ISO ******2. The CAN-PCIe/****4/2Slot comes with two CAN interfaces via a separate slot bracket. These product versions are also available without electrical isolation. In the CAN-PCIe***-B4/1Slot version all four CAN interfaces are connected via one **-pin DSUB connector. Equipped with up to two CAN interfaces the board is available as low profile versions (CAN-PCIe/*****-LP and -LP2).

CAN Data Management

The independent CAN nets according to ISO ******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 CAN-PCIe/**2 can be operated for example in Hypervisor environments.

The CAN-PCIe/**2 provides high resolution hardware timestamps.

Software Support

CAN layer 2 (NTCAN-API) software drivers are available for Windows, Linux, VxWorks, QNX, RTX and RTX*4. The CANopen software package is available for Windows, Linux, RTX, VxWorks and QNX. Drivers for other operating systems are available on request.
