Figure 5-1. Data Blocks

The write tag (WT) command ASCII string is limited to 63 characters.

Each WT command ASCII string is limited to a maximum of 63 characters. For a 256 byte RFID tag, a maximum of four WT commands containing 63 characters of data may be used.

NOTE: It is the user’s responsibility to track the 63 character maximum. If more than 63 characters are included in a WT command, the command will fail.

The read tag (RT) command stores data in a user-specified location.

The RT command retrieves data from an RFID tag and stores the data in a location that the user identifies. The location is identified with a number between 1 and 99. The user may store the result of a maximum of 32 separate RT commands.

The RT command reads up to a specified ending block or until a null character is encountered.

The RT command reads data from the RFID chip beginning at the block specified in the command parameter. The command will continue to read up to the block specified in the command parameters OR until a null character is encountered. The RT command will not read past the null character.

Again, refer to Figure 5-1. Reading blocks 0-3 returns “COGNITIVE PRINTE”. Reading blocks 0 through 4 returns “COGNITIVE PRINTERS”. Finally, reading blocks 0 through 5 returns the same string as reading blocks 0 through 4.
