After this command is received by the Hand-held Reader Writer, data is written to the Data Carrier by
pressing the activate switch. If the activate switch is pressed and the Data Carrier is not in communica-
tions range, an error response (end code: 72 = Data Carrier non-existent) will be returned.

Sets the code format used to send responses for read data.
A: ASCII
H: Hexadecimal code
When multiple processing areas are used, ASCII and hexadecimal code can be specified at the
same time within a single command frame.
Specifies the processing area number.
Setting range: 1 to 9, A (A = 10)
Specifies the start address of the area in the Data Carrier to be written to in 4-digit hexadecimal
code.
Setting range: 0000h to 1FFFh
When multiple processing areas are used, specify the areas in order starting from the smallest
address. The same area cannot be specified twice.
When multiple processing areas are used, specifies the number of bytes to be written to the Data
Carrier in 2-digit hexadecimal.
The maximum number of bytes that can be written at one time is 256 bytes.
•ASCII: 256 bytes (256 characters)
•Hexadecimal code: 256 bytes (512 characters)
Setting range: 01h to FFh
When multiple processing areas are used, set so that the total number of bytes to be written for all
areas is within 256 bytes, as follows:
Area (1) bytes +...+ Area (N) bytes ≤ 256 bytes
Indicates the data to be written to the Data Carrier.
The characters in ASCII indicate the number of write bytes and the characters in hexadecimal code
indicate the number of write bytes x 2.
