CHAPTER 4 ALIEN READER PROTOCOL
READER INTERFACE GUIDE
DOC. CONTROL # 8101938-000 REV 05

When the RFID Reader is required to print a TagList, the tokens in the custom
format are replaced with the actual values for each tag.
Tokens Description
%i
Tag ID with a white space between each pair of bytes i.e.,
8000 00FE 8010 2AB7
%k
Tag ID with no spaces between i.e.,
800000FE80102AB7
%d
Discovery date of tag, in format YY/MM/DD
%t
Discovery time of tag, in format hh:mm:ss
%D
Last Seen date of tag, in format YY/MM/DD
%T
Last Seen time of tag, in format hh:mm:ss
%r Read Count of tags, i.e., how many times the tag has been
read
%a Antenna the tag was last seen at (for the ALR-9800, this is
the transmit antenna)
%A (ALR-9800 only) Receive Antenna where the tag was last
seen
%p (ALR-9800 only) Integer value indicating the tag's protocol
(0 = Class0, 1 = Class1/Gen1, 2 = Class2/Gen2)
%P
(ALR-9800 only) String representation of the tag's protocol
TagListCustomFormat Examples
Command
Response
Get TagList
>set TagListCustomFormat = Here is a tag %i
TagListFormat = Here is a tag %i
Here is a tag 8000 0000 0000 0808
Here is a tag 102F ED3D 0303 0001
Command
Response
Get TagList
>set TagListCustomFormat = Tag %k, read %r times from
antenna %a
TagListFormat = Tag %k, read %r times from antenna %a
Tag 8000000000000808, read 3 times from antenna 0
Tag 102FED3D03030001, read 120 times from antenna 1
TagListAntennaCombine
9800 | 9780 | 8780 | 9640 | 9774
The TagListAntennaCombine command turns on or off the antenna combine
mode. When TagListAntennaCombine is ON, the reader combines tag IDs into a
single TagList even if the Ids are read by different antennas. Setting this value to
OFF forces the TagList to keep multiple copies of a tag ID for each antenna
where it is seen.
For example, reading a tag that is visible to both antenna 0 and antenna 1, with
an AntennaSequence of "0,1", would give the following TagList:
