Communications Commands
Details of communications commands used to communicate with the ID Tag are provided here.
■ READ (RD)
This command reads data from the ID Tag. If the ID Tag is not in the communications area, an error
response (end code: 72 = ID Tag non-existent) will be returned.
Processing area number: 1
Processing area number: 2
Data setting Sets the code format used to send responses for read data.
A: ASCII
H: Hexadecimal
When multiple processing areas are used, ASCII and hexadecimal can be specified at the same
time within a single command frame.
Processing area number
setting
Specifies the processing area number.
Setting range: 1 to 9, A (A = 10)
Read area start address Specifies the start address of the area to be read from the ID Tag in 4-digit hexadecimal.
Setting range: 0000 to FFFF hex
When multiple processing areas are used, specify the areas in order starting from the smallest
address. The same area cannot be specified twice.
Number of bytes to read Specifies the number of bytes to be read from the ID Tag in 2-digit hexadecimal. The maximum
number of bytes that can be read at one time is 256 bytes, as follows:
• ASCII: 256 bytes (256 characters)
• Hexadecimal: 256 bytes (512 characters)
Setting range: 00 to FF hex (00 = 256 bytes)
When multiple processing areas are used, set so that the total number of bytes from all areas to be
read is within 256 bytes, as follows:
Area (1) bytes +...+ Area (N) bytes ≤ 256 bytes
