SetFilter
This method can be used to set a filter for certain parts of
the EPC and the TID. Furthermore, the minimum and
maximum values of the RSSI to be achieved and the EPC
length can be set.
In synchronous scanning mode, only the data carriers
whose data match the settings of the filter are displayed
after the filter is activated. An example of the application
can be found on page 226.
Min. Access Level: Expert
Default value: The default value is set via the device
parameterization (see chapter 7.3 on page 49).
