(2) Write ID (WTID)<br />
Command<br />
WTID(S)WriteData(S)[Options...]<br />
WriteData: Data to be written in 4-digit hexadecimal number (Max: 128 characters).<br />
Response WTID[RC](S)[CNT](S)[ITM1]<br />
[RC]: Response Code<br />
[CNT]: Tag Count<br />
[ITM1]: Items indicated by TIF option. Items are delimited by a comma.<br />
Note:<br />
・ If EPC/PEP/PER are specified for TIF, EPC data shall be the data before rewrite. If<br />
data length is zero during EPC specification, data shall become ”*”.<br />
*(S) Space character<br />
Example 1) When all option values are default values and ID 1234567890ABCDEF12345678 is specified, the<br />
command is executed and write process has been completed successfully:<br />
[Tx] WTID 1234567890ABCDEF12345678<br />
[Rx] WTID0000 001<br />
Example 2) When ID "555555555555555555555555" and EPC code are specified for write data and tag<br />
information, the command is executed and then the reader has succeeded.<br />
[Tx] WTID 555555555555555555555555 -tif EPC <br />
[Rx] WTID0000 001 444444444444444444444444<br />
* If -tif is specified for EPC code, tag’s EPC data before rewritten is returned. If the tag had an EPC<br />
data "444444444444444444444444" as last ID, response is as above.<br />
Example 3) When 1234567890ABCDEF12345678 and antenna are specified for write data and tag information,<br />
the command is executed and then the reader has succeeded to write data with antenna 1.<br />
[Tx] WTID 1234567890ABCDEF12345678 -tif EPC,ANT<br />
[Rx] WTID0000 001 *,1<br />
* If the tag had no EPC data before, [*] is returned.<br />
Example 4) When FFFFFFFFFFFFFFFFFFFFFFFF, 2, and 300 are specified for ID, antenna, timeout and the<br />
command is executed but no tag is found:<br />
[Tx] WTID FFFFFFFFFFFFFFFFFFFFFFFF -ant 2 -tmo 300<br />
[Rx] WTID0000 000<br />
Example 5) When 123412341234123412341234 and ABCDABCD are specified for ID and access password is<br />
executed but access password is not matched:<br />
[Tx] WTID 123412341234123412341234 -pwd ABCDABCD<br />
[Rx] WTID0000 000<br />
Example 6) When an error has occurred during communication process:<br />
[Tx] WTID 1234567890ABCDEF12345678<br />
[Rx] WTID7012<br />
* The error code [Code:7012] is returned.<br />
