Fast CAN FD for the USB Interface

(PresseBox) (Darmstadt, Germany, ) AN FD, the evolution of the proven CAN bus, can now be connected to PCs with two USB interfaces from PEAK-System. While PCAN-USB FD offers a single CAN FD channel, PCAN-USB Pro FD has two CAN FD and two LIN channels, distributed on two D-Sub connectors. The CAN FD channels are each galvanically isolated up to 500 V. The interfaces can reach transfer rates of up to 12 Mbit/s for the maximum 64 data bytes of a CAN FD frame. Both products make use of the USB 2.0 standard, ensuring a lower latency than on USB 1.1. Device drivers are available for Windows 8.1, 7, Vista, as well as Linux.

The included monitoring software PCAN-View for Windows is released in version 4 as part of the CAN FD enhancements. Besides the previous hexadecimal representation of data, this can now be displayed in decimal or in ASCII format. Moreover, the PC interfaces can be set to listen-only mode for CAN bus analysis. Both PCAN-USB FD and PCAN-USB Pro FD are able to show the physical bus load with PCAN-View and can specifically generate errors in CAN communication.

With version 4, also the free PCAN-Basic API for Windows receives the support of the new standard, allowing the connection of own software to CAN and CAN FD busses.

Additional information about CAN FD

With CAN FD (Flexible Data rate) the robust and long lasting CAN specification has been extended with properties which are primarily designed for larger amounts of data. Higher data bit rates up to 12 Mbit/s and the use of up to 64 data bytes in a CAN frame are the main criteria.

CAN FD is downward-compatible to the CAN 2.0 A/B standard, thus CAN FD nodes can be used in existing CAN networks. However, in this case the CAN FD extensions are not applicable.
