IMPORTANT For all examples make sure Label Length in the QUICK SETUP
menu matches the physical length of the installed media.
Read Tag
Purpose This command allows data from the RFID tag
(embedded in the smart label) to merge into any
previously defined dynamic data field. It is equivalent to
the Field Number command (^FN) except that the data
come from the RFID tag.
Format ^RT x, start, length, hex, retries, motion, reserved
^RT Read Tag command.
x Specified Field Number (value assigned
to the field). The default is 0. The
acceptable value range is 0 to 9999.
start Location where data will be read from the
RFID tag. The PPI/ZGL only supports
Alien Technology Class 1a tags, which
have only one 8–byte or 12–byte block.
Therefore,
start will be set to 0,
regardless of the specified value.
length The number of blocks to be read from the
RFID tag. The PPI/ZGL only supports
Alien Technology Class 1a tags, which
have only one 8–byte or 12–byte block.
Therefore,
length will be set to 1,
regardless of the specified value.
hex 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.
