FlexCard USB – Flexible, small, robust and powerful

The FlexCard USB, robust and powerful, is a multifunctional USB interface for analysing and monitoring FlexRay and CAN bus systems. The incoming messages are evaluated quickly in real time. Thanks to its varied monitoring functions, the FlexCard USB can be used purely as a monitoring tool or as a genuine communications partner. Even ECUs that do not provide start-up synchronisation frames can be tested with the integrated FlexRay CC, which transmits a second start-up synchronisation frame.

The FlexCard USB can be used for laboratory use, prototype set-ups and measurements directly in the vehicle. Flexible handling is assured by the USB connection and compact dimensions. Integration in the Eberspächer Electronics tool chain makes use of the board very simple. An included API provides comprehensive functions for the usage of the FlexCard USB.
