PCAN-USB FD – User Manual

Introduction
The CAN FD adapter PCAN-USB FD allows the connection of CAN
FD and CAN networks to a computer via USB. A galvanic isolation
of up to 500 Volts decouples the PC from the CAN bus. The simple
handling and its compact plastic casing make the adapter suitable
for mobile applications.
The new CAN FD standard (CAN with Flexible Data rate) is primarily
characterized by higher bandwidth for data transfer. The maximum
of 64 data bytes per CAN FD frame (instead of 8 so far) can be
transmitted with bit rates up to 12 Mbit/s. 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.
Device drivers and programming interfaces exist for different opera-
ting systems, so programs can easily access a connected CAN bus.
Tip: At the end of this manual (Appendix C) you can find a
Quick Reference with brief information about the installation
and operation of the PCAN-USB FD adapter.
