Web Based Application Examples
As part of the standard functionality of the Nanoscanner reader, the built-in web
server is able to serve up a simple web based application example.
This application example can be found under the last tab on the Web pages,
named “Applications.” Under this tab is a simple Applet running two applications
that use reader commands. These provide an interactive environment for reading
tags in the field.
NOTE: The Java Applets are all Java 1.1 compliant applets and will work in
standard Netscape and Internet Explorer browsers.
Readometer
The “readometer” graphically displays a single tag and antenna information in
real time.
This screen allows the user to:
• View a single tag (as returned by the Get TagList / Set AcquireMode= Global
Scroll command) and the reading antenna
• View a cumulative and dynamic number of reads since starting or resetting
this value
• View a dynamic Reads per Second value for the current tag
• Change the antenna sequence (see “General Commands”)
• Reset the Total Reads counter
• Stop/start the tag reading operation
• Switch to a different display mode
