(4) Write Data (WTDT)
Command WTDT(S)MemoryBank(S)DataPointer(S)WriteData(S)[options...]
MemoryBank: Memory Bank
DataPointer: Data Pointer
WriteData; Data to be written
Response WTDT[RC](S)[CNT](S)[ITM1]
[RC]: Response Code
[CNT]: Tag Count
[ITM1]: Items indicated by TIF option. Items are delimited by a comma.
Note:
・ If EPC/PEP/PER are specified for TIF option, EPC data shall be the data before
rewrite. If data length is zero during EPC specification, data shall become ”*”.
*(S) Space Character
Example 1) When [Memory bank; 0, Start address(=Data pointer); 0, Data; 0x1234 (one word)] is specified,
other setting are default and then the write process has been succeeded:
[Tx] WTDT 0 0 1234
[Rx] WTDT0000 001
Example 2) When [Memory bank;1, Start address(=Data pointer); 3, Data; 0x1234567890ABCDEF12345678,
Antenna; 2 and 3, Timeout; 200, Tag information; antenna id] is specified:
[Tx] WTDT 1 3 1234567890ABCDEF12345678 -ant 23 -tmo 200 –tif ANT
[Rx] WTDT0000 001 2
* In this case, the response code has an antenna ID which is used in writing process.
Example 3) When specified address is not supported:
[Tx] WTDT 1 8 12345678
[Rx] WTDT0000 000
* No count response is returned.
Example 4) When specified address is locked:
[Tx] WTDT 0 0 AAAAAAAA
[Rx] WTDT0000 000
* No count response is returned.
Example 5) When [Memory bank; 1, Start address=(Data pointer); 2, Data; 0xABCDEFGH] is specified and a
format error has occurred:
[Tx] WTDT 1 2 ABCDEFGH
[Rx] WTDT1412
* The error code [Code:1412] is returned.
Example 6) When an error occurred during communication process:
[Tx] WTDT 1 32 1234567890ABCDEF12345678 -ant 23
[Rx] WTDT7011
* The error code [Code:7011 (in this case)] is returned.
