DATA FILL (DF)
For DATA FILE, the ID Controller waits for a Data Carrier to approach and then fills Data Carrier
memory with the specified number of write bytes from the start write address specified in the
command. If there is no Data Carrier in the communications area, an error response with an error code
of 72 (Data Carrier missing) will be returned.
Data will also be written to write-protected areas of the Data Carrier. Be sure that there is no important data in the write
area before executing this command.

2: Read/Write Head 2
Specifies the first address to which to write data to the Data Carrier as a four-digit hexadecimal
number.
Specifiable range: 0000H to FFFFH
When specifying in odd bytes, this writes the 1 digit prior to the designated data for ASCII code
specification, or the 2 digits of the designated data for hexadecimal specification, to the last 1 byte
of data in the Tag.
Specifiable range: 01H to FFH, 00H (The maximum of 256 bytes will be written if 00H is specified.)
The data to write to Data Carrier memory.
• ASCII specification: Specify 2 bytes.
• Hexadecimal code specification: Specify 4 bytes.
Indicates the results of command execution. An end code of 00 is returned for a normal end.
