RFID Overview
The printer has two different operational modes for the programming of RFID tags:
Direct, and Label Formatting.
The RFID programming data can be entered in one of two formats: ASCII, or
Hexadecimal. Data in the ASCII format is entered conventionally, while data in the
hexadecimal format is entered as the hexadecimal-pairs equivalent of the ASCII
character(s). For example, to program the word “TEST” in the ASCII format, the data is
entered as TEST; alternately, in the hexadecimal format the word is entered as
54455354.
The other important consideration is the data format byte count. Compared to the
ASCII format, hexadecimal formats use twice the number of bytes. Returning to the
example above, in the ASCII format “TEST” has a byte count of four, while the
hexadecimal format equivalent has a byte count of eight.
To send information about the results of tag printing back to the host, refer to the OF
Option Feedback Mode command for option feedback.
Direct Mode
Direct Mode allows the user (host) to directly control the reading and writing of RFID
tags. This mode contains both a generic Read / Write Interface and a high level HF /
UHF Tag Interface. In Direct Mode, each RFID tag is individually processed with status
and data responses. Typically these commands are used for diagnostics or custom
applications.
Generic Read/Write Interface
The Generic Read/Write Interface allows the Host Application to send generic
commands for RFID operations by utilizing the printer’s database for specific
parameters. Requiring no knowledge of the tag types being used (except the data
format), these commands consist of simple read and write operations. See the STX
KaR Read Data from RFID Tag and STX KaW Write Data to RFID Tag commands for
details.
HF (13.56 MHz) ISO15693 Tag Interface
The ISO15693 Tag Interface allows the Host Application to perform specific
operations pertaining to HF-type (13.56 MHz) tags. Since these commands override
the printer’s database by interfacing directly to the tag module, knowledge of HF tags
and their operation is required. See the STX KtA Write Application Family Identifier
(AFI) to Tag, STX KtD Write Data Storage Format Identifier (DSFID) to Tag, STX KtE
Write Electronic Article Surveillance (EAS) Bit, STX KtH Read and Feedback Tag
Information to Host, STX KtR Read Data from RFID Tag, STX KtU Read Unique Serial
Number from RFID Tag, and STX KtW Write Data to RFID Tag commands for details.
