All parameters must always be transferred together. If the reader configuration is not saved on the host, it is recommended
to first read out the parameters saved to the reader.
"Read status" telegram
The status that can be read out from the reader includes version information alongside the parameters.
Either the retentive or the non-retentive parameters can be read out; the version information is always the same.
After the acknowledgement is sent with the requested data, the reader switches automatically back to scan mode.

"Activate test mode" telegram
A test mode can be set to support the commissioning of a reader. The test mode is immediately active in the reader after the
acknowledgement is sent and can be deactivated only by switching off the reader or by sending a new parameter set.
In test mode, the reader scans constantly for a tag. Successful scans (a tag has responded) and unsuccessful scans
(incorrect or no response from a tag) are counted. The number of successful scans is permanently transferred to the host by
the reader. The reference point is 20 scans.
The transferred value provides information about how well a tag is positioned in, or passes through, the reader's HF field.
