Interpreting Tag ID Code Information
Table 2 lists the default data formats that are transmitted from the Panel Reader’s serial
communications port, in response to reading compatible type tags. For ISO type tags, there is
no difference between HDX and FDX-B outputs. Both types of tags produce a default
format:
LA_982_000001088420<CR><LF>
where the underscore “_” represents a space character, and <CR><LF> is a carriage return
/line feed (unprinted control characters which cause a PC’s display cursor to jump to the
beginning of the next line prior to displaying the next ID number).
In the above data output, the prefix “LA” represents “line mode – animal coded read only
tag”, “982” is the Allflex manufacturer number assigned by ICAR, and the last 12 digits
comprise a unique number sequence for this particular transponder.
The TIRIS S2000 output format has become a de facto standard for many users, and appends
the reserved field and data block bits contained in the ISO coded eartag to the Panel Reader’s
default format, causing the ID code information to appear in the format:
LA_00000_0_982_000001088420<CR><LF>
This output is easily configured using either the Configurator® utility, or by issuing the
Command “BE40239” to the Panel Reader (see “Configuration Options”).
Note - The manufacturer code “982” will be different for another manufacturer’s tag, and
can also be replaced by an ISO country code (“250” = France, for example). When other
manufacturer codes or country codes exist, there can exist the same 12 digit ID number.
Note - While HDX and FDX-B type transponders have an identical context, they are
guaranteed by Allflex to be unique. That is, HDX tag type ID numbers are never duplicated
in FDX-B type tags.
For HDX Industrial coded tags, the output format is:
LR_0006_0000000018514348<CR><LF>
In this tag format, the prefix “LR” represents “line mode – industrial coded read only tag”,
“0006” is an application code unique to Allflex, and the last 16 digits comprise a unique
identifying number sequence.
