The field number to whichthe data will
be assigned. The default is 0, and other
acceptable values range from 1 to 9999.

one 8–byte block. Therefore,
startblock
will be set to 0, regardless of the
specified value.
length

RFID tag. The PPI1 only supports Alien
Technology Class 1a tags, which have
only one 8–byte block. Therefore,
length
will be set to 1, regardless of the
specified value.
hexformat
This flag indicates whether the data, after
being read from the RFID tag, should be
translatedinto hexadecimal format. The

translated.The other acceptable value is
1, meaning the data will be translated
into hexadecimal format.
