Basic Reader Interface Programmer Reference Manual
Error 2:
MEMOVRN<CRLF>
OK><CRLF>
This error indicates that the address used in the WRITE command was not available
on the tag. This is only returned when the TAGTYPE attribute contains EPCC1G2.
Error 3:
PVERR<CRLF>
OK><CRLF>
This error indicates that an incorrect password has been provided when writing to
an EPCglobal Gen 2 tag, or the address being written has previously been locked.
Error 4:
PWERR<CRLF>
OK><CRLF>
This error indicates that the tag did not have enough power to complete the WRITE
command when writing to an EPCglobal Gen 2 tag.
Examples:
These examples demonstrate how to use the WRITE command.
Example 1:
WRITE INT(10,2)=3 HEX(12,2)=H12CD TAGTYPE=G2
The data field parameters specified above will write at tag memory address 10, and a
value of 3 will be written. The data 0x12 and 0xCD will be written to locations 12
and 13 respectively.
Example 2:
WRITE STRING(18,5)=“HELLO” TAGTYPE=G2
This WRITE command with a [WRITE FIELD] parameter writes all tags found with
the data
HELLO
starting at address 18 in the tag. Each tag written responds with the
status of the WRITE command terminated with a
<CRLF>
. When all tags are
written, the BRI returns
WROK<CRLF>OK><CRLF>
. If no tags are written, the BRI
returns
NOTAG<CRLF>OK><CRLF>
. Here is an example response when a single tag
is written:
WROK<CRLF>
OK><CRLF>
For an EPCglobal Class 1 Gen 2 tag, this example returns the ADERR error response
because the data to be written does not have an even length:
WRITE STRING(10,5)=“HELLO”<CRLF>
ADERR<CRLF>
Here is a valid WRITE command for an EPCglobal Class 1 Gen 2 tag:
WRITE STRING(10,4)=“GOOD”<CRLF>
WROK<CRLF>
OK><CRLF>
Example 3:
WRITE STRING(10,5)=”HELLO” TAGTYPE=G2
WHERE TAGID=H1234567890ABCDEF
