Visualization and Recording of CAN Data




PCAN-MiniDisplay Case



The PCAN-MiniDisplay is used as a human-machine interface for the visualization of CAN data. For the connection to the CAN bus, it has two High-speed CAN connectors. The graphic representation of incoming CAN data is configured before using the unit and then is performed on a TFT display.

The PCAN-MiniDisplay can alternatively be used for data logging. The data traffic is recorded to a memory card and can be replayed or analyzed on a PC later on.

In addition to the built-in PCAN-MiniDisplay, there is a version in plastic casing with push buttons available. This can be used to create and evaluate application-specific configurations. Furthermore, the user can directly switch between different configurations during operation.




Running a display configuration as well as recording and playback of CAN messages is not possible at the same time. The PCAN-MiniDisplay can only be used with one of the three functions.
