2.3. Auto-Answer-Mode
In this operation-mode the reader self-initialized sends out data to the host as soon as a transponder
is within the detection range and a positive plausibility check of the data has been executed.
Turned to Auto-Answer-Mode the contents of the message block (Serial-No., ID-Number, data block,
protocol following time) and message cycle (protocol block, locking time, reception) can be adapted to
each other according to the user-application. The data will be put out depending to their configuration
according to the following scheme, of which the order cannot be changed.

Data blocks (free programmable)
tr:
time to new reading of the
information of the transponder
(see annex B: Time behavior)
The reader starts the output of the protocol block as soon as all required data have been read
correctly from the transponder. If the reader is not able to read all data of a protocol block completely
and faultlessly, it doesn't put out data, unless the reader recognizes by the type of transponder that the
required data cannot be found on the transponder.
Note:
It is strongly recommended not to bring any transponder into the detection range of the reader
in if configuration commands shall be send to the reader while the Auto-Answer-Mode is
active.
