Note
Check to see that at least one antenna port is connected before performing any tag
queries or tag write operations.
Query Page
Use the Astra Query Page to set up and run Anti-Collision Searches quickly, and to obtain
immediate feedback. This is useful for debugging as well as for verifying performance
after installation is completed.
If the Query page does not load and you do not see the Java logo, install the Java
Runtime Environment for Windows and restart your PC.
Read Tags
The Query Page enables you to read tags and select an appropriate query.
To read tags:
1. Position one or more tags, in front of one of the antennas connected to the
Reader.
2. Do one of the following:
Select an appropriate query from the drop-down list at the bottom of the
screen next to the Query field.
Enter an RQL search statement.
For example, select "fewer than 10 GEN2 tags" from the list.
Note
Reader performance is optimal when the most appropriate query is selected.
The RQL search statement in the Query field specifies which antenna is to be used, how
long the query is to be run, and other read operation parameters. The query can be run
once or continuously.
To initiate and stop a query:
1. Click the Start button at the bottom right of the Query Page.
The Reader will continuously read the tags and display the tag data. Each row in
this example shows sequential tag number, number of times tag was read, tag
data, antenna, and protocol.
2. Click Stop to stop the tag search.
