Sent datatype
The RFID transponders are from general to allow the verification of the correctness of the data
stream in either parity bits, or using ’checksum’. The Proxer7 reader verifies the correctness of the data
stream in all cases. It also happens that the transponder’s physically printed ID came from the given
sequence of data stream. So we talk decoded and undecoded data stream. In both cases the data stream
identifies the card. The decoding is the recover to the provided number by the manufacturer, the possibility
of individual identification with the transponder is not affected.
The undecoded data stream will be in all cases in hex format forward.

Explanation
Decoded
If the identification of the RFID type is successful and the decoding information is
available, the reader decrypts the specified identification number by manufacturer’s and
then transmits via communication interface to the user.
Undecoded The RFID transponder ID will be sent to the PC 1:1, only in hex format
Sent number of characters
The needed characters to the identification of RFID ID may be different, depending on the size of
the ID number (the larger the number, the more characters can be represented only). If the connected system
wait for constant number of character sending, namely does not handle the dynamically changing number of
character IDs, in case of that should be send the independent of the size of ID number, which can be made
with this parameter.
If the ID does not fit the here defined number of characters, the Proxer7 automatically send at the
length which good for it. If the ID would be fit on shorter character, as the here defined, the Proxer7
supplement. (See under „
Additional character” parameter).
If the ID does not fit the here defined number of characters, but do not want the Proxer7 send more
characters because of foregoing, needed the size of ID reduce with the ’sent number of bits’ parameter.
The following example illustrates the operation described above. The value of the additional
characters is „0” currently. It is assumed that sending the decoded data stream is set, so the Proxer7 reader
will send a decimal number.
