Table 12 Programmer Response Codes
Code Response
Description
00
Operation
successful/ no error
The last operation performed by the programmer was executed
without errors.
01 Illegal command Invalid command sent to the programmer.
02 Invalid tag data
The user data sent to the programmer was in the incorrect
format (such as an illegal hex character).
03
Presence time-out
on program cycle
The programmer did not recognize the placement of a tag in the
tag holder during the 10-second period prior to a programming
sequence.
04
Presence time-out
on verify cycle
The programmer did not recognize the placement of a tag in
the tag holder during the 10-second period prior to a verification
sequence.
05, 06, 07 N/A Reserved
08 Data compare error
During a programming sequence, the data read from the tag did
not correspond to the user data that was written to the tag.
09 Locked tag
The programmer has detected a lock condition of the tag. The
tag data is stored permanently and cannot be changed.
0A No frame marker
The programmer could not decipher a frame marker from the
tag. Either the tag is not in the tag holder, is damaged, or the RF
is not being generated and programming and/or verifying the
tag data can not occur.
0B Bad tag parity
The checksum bits read from the tag did not correspond to the
checksum that the programmer calculated from the tag data.
0C
Security code
operation
The AP4119 has detected an attempt to write illegal security
characters to the security character positions of the tag’s ATA
frame data. The AP4119 has then coded the SPACE character in
the positions, therefore altering the user’s original tag data.
0D Invalid permissions
This programmer does not have permission to write data to the
tag address that the user requested.
