4-3 Commands and Responses during CR Control
2) Write
Use this command to write tag data on a page basis. Data can be written to user-specified pages (except
B Hex to E Hex for I-CODE1). The maximum number of pages which can be written to in a single op-
eration is one bank, and writing to pages across banks is impossible. There is no need to perform the
verify read process, since this command performs it as part of its execution.
Command
This command sends the data to be written as parameters. The page specification is as follows: The bits
that correspond to the pages to be written are set to 1, and all other bits are set to 0. This binary number
is converted to hexadecimal and sent with the command. Specify the write data sequentially in as-
cending order of the specified page. In the case of a Tag equipped with I-CODE1, specify the write data
in the order: F⇒0⇒1⇒···⇒A.
Command

ISO chip
*1
Number of data n = Number of specified pages x 8 (hexadecimal)
Number of data n = Number of specified pages x 4 (ASCII)
Response
The response returns the end code (normal end: '00').
End code
' 0 '

Command Example
The following table gives details of tag user memory when executing the following command.
(1) Writing 52464944 hexadecimal to page 8, and 56373230 hexadecimal to page 10 using FIFO
Repeat Mode, with hexadecimal:
Command '02 0B 0500 52464944 56373230<CR>'
Response '00<CR>
(2) Writing 'RFID' hexadecimal to page 8, and 'V720' hexadecimal to page 10 using FIFO Repeat Mode,
with ASCII:
Command '02 1B 0500 RFID V720<CR>'
Response '00<CR>'
Data written to tag memory is the same for both (1) and (2).
