Area (1) setting
Specifies 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 read from 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 read from the Data
Carrier in 2-digit hexadecimal code.
The maximum number of bytes that can be read at one time is 256 bytes.
•ASCII: 256 bytes (256 characters)
•Hexadecimal code: 256 bytes (512 characters)
Setting range: 00h to FFh (00 = 256 bytes)
When multiple processing areas are used, set so that the total number of bytes to be read for all
areas is within 256 bytes, as follows:
Area (1) bytes +...+ Area (N) bytes ≤ 256 bytes
