ContactThe filter block is used to intentionally reduce the volume of data. Furthermore, individual messages and network nodes can also be configured in the filter block.
With a channel filter it is possible to completely block or open the channels of all registered bus systems (CAN, LIN, MOST, FlexRay).
When pass filters are configured only the specified messages, message ranges and/or messages of a particular network node are passed. In contrast, stop filters can be used to intentionally mask out specific ranges from the data stream.

- Events are selected from an associated database, a list of predefined events from CANdb, or a MOST XML function catalog.
- Raw Data is entered as a single message ID or a range of IDs.
- Nodes affect all traffic coming from a given network node.
- Hook Events are only available if you have added a Hook DLL to expand the functionality of the measurement. Hook DLLs are very advanced and should be used at the users own risk.
- Filtertype sets what type of filter is going to be used. A filter can either be a stopfilter or a passfilter, never a mix of the two.
Once an event has been selected to be filtered, you now have options on how to filter this event.
