Air protocol selection defines the type of tags that the reader can expect to see. "C3" type tags is the default
value.
At any given time, C1G2 tags or only C3 tags can be read, or the user can . select both types for a single
round of reads.
Note that in E-Manifest application, this function is inoperative, and C1G2 and C3 are both employed.

3. Setting a Configuration (drop down list box)
A facility to load pre-determined config files is available via the drop-down menu under settings. There,
you will find the configuration(s) that you have set up in the Custom window and saved.
All files when created or modified are padded with the .ifx suffix.
4. Antenna selection (checkboxes)
The user interface supports up to four antennas. By default, at least one antenna i.e. Ant-1 is selected.
Check / un-check the Ant -1, -2, -3, -4 boxes according to the number of antennas connected to the
associated ports on the reader.
Be sure to connect 50 ohm loads to unused antenna ports on the Transmit connectors.
5. Tag Inventory (operation)
Select “Find Tags” and a screen will be displayed listing tags found with EPC numbers, and the options of
“Manage Tag Memory” and “Raw Memory Read/Write”. The number of tags found is also shown at the

1.2.4.2 Sequence of events after triggering “Find tags”
Although the actual algorithm and the code that runs in the background is highly sophisticated, in very
general terms the following is the high level protocol used to detect tags:
1) The reader sends out a “query” command via RF link between the antenna/s and the tags
2) Tags that respond by a issuing a query reply are flagged as such or singulated.
3) Depending upon the config file, this procedure may repeat itself several times or until the internal

3) Depending upon the config file, this procedure may repeat itself several times or until the internal
state machine completes its execution.
Once the tags are found, the output is shown as follows:
