UHF Interface
This interface allows the Host Application to perform specific operations pertaining to
UHF-type tags. Since these commands override the printer’s database by interfacing
directly to the tag module, knowledge of UHF protocols and their operation is
required. See the STX KuR Read Data from RFID Tag and STX KuW Write Data to RFID
Tag commands for details.
Label Formatting Mode
Label Formatting Mode utilizes the current printer configuration to process all
reading, writing, and exception processing for each tag printed. (For exception
processing and fault handling; see the FH Fault Handling command.) The
specification for RFID programming is contained in the data fields of the DPL label
format, which instructs the printer to write and read data. Two Label Formatting
Modes for RFID are available. While each supports auto increment and decrement
commands for numeric (+/-), alphanumeric (>/<), or hexadecimal ((/)) data, they differ
when a byte count specifier is added.
Note: Up to six RFID operations per label are allowed.
