ZGL RFID Commands

Read Tag ^RT

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

Comments This command is only executed by the demand for data from any dynamic field. The ZGL ab-
sorbs this command if there are no demands for the data

Read Tag command.
Specified Field Number (value assigned to the field). The default is 0. The
acceptable value range is 0 to 9999.
Location where data will be read from the RFID tag. The 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.
The number of blocks to be read from the RFID tag. The 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.
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.
The number of automatic attempts to read data from the tag if previous reads
failed. The ZGL absorbs the number and uses the value on the control panel's
LCD.
Set this flag to 1 to read data from the tag without moving the label. The printer
may adjust the label position while it reads data from the tag, but this adjustment
will reverse before any subsequent normal label movement. Even if this flag is set
to 1, other commands (i.e., alpha or barcode) may move the label.
This is a reserved flag. The ZGL absorbs this number.
