^RT Read Tag command.
x
The field number to which the data will
be assigned. The default is 0, and other
acceptable values range from 1 to 9999.
startblock
Location where data will be read from the
RFID tag. The PPI1 only supports Alien
Technology Class 1a tag, which has only
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
translated into hexadecimal format. The
default is 0, meaning the data will not be
translated. The other acceptable value is
1, meaning the data will be translated
into hexadecimal format.
retriescount
The number of automatic attempts to
read data from the tag if previous reads
failed. The PPI1 absorbs the number and
uses the value on the operator panel.
