2. Kill
The UPDATE command is also used to initialize
a tag. 3 parameters must be specified in SET
Clause. The first is 'killed' flag, the second is
password for the tag and the last is id of the tag.
The structure of an UPDATE command is the
same as ID Write.
• Example : To lock tag id of a 64-bit EPC tag:
UPDATE tag_id SET killed=1,
password=0x88, id=0x1234567890ABCDEF
WHERE protocol=’EPC1’ AND antenna_id=1;
The reader returns the tag_id if the kill operation
was successful. For example the response is as
follows:
||0x00000000000000000000<LF><LF>
If succeeded, the response of kill command is all
0.
If the operation is failed, "Error 0102: Error
performing query<LF><LF>" returned.
• Example : To lock tag id of a 96-bit EPC tag:
UPDATE tag_id SET killed=1,password=0x88,
id=0x1234567890ABCDEF12345678 WHERE
protocol=’EPC1’ AND antenna_id=1;
The reader returns the tag_id the same way as 64-
bit tag.
Note: The format of the tag data in the command
must much the selected protocol or an error will
result. (See section 1.6)
For example :
- A 64 bit EPC1 tag requires 16 hexadecimal digits
- A 96 bit EPC1 tag requires 24 hexadecimal digits
Note: You must send this command to only one tag
at one time in the stable communication area.
Note: Response data always contains 2 separators
in front of the tag ID.
Note: After sending this command, you must send
an ID read command and confirm no ID data is sent
as a response.
