RFID Data Views
Overview
The Tracer provides several views that allow users to examine RFID data from different
perspectives. Use the View menu (on the main window) to select different views.
Tracer provides two types of data views:
z
Live data views, which are captured in real-time from the reader
z
Post-capture views, which are generated after an operation is completed
The live data views display data as the packets arrive from the reader. The application applies
minimal processing to this live data. The following table describes the three live data views that
are available.

Summary View
Overview statistics about the current session, currently executing
command and reporting time slice.
Standard View
A list of unique tag singulations (tag id inventoried) in the session and a
count of the number of times the id was read (inventoried).
Protocol Trace
A graphical view of the packet data for the current (active) command
broken out by the packet fields.
Note that while a reader is actively executing a command, such as Inventory, only live data
views are available. Even if a user has selected a post-capture view, the view is automatically
switched to a live data view when a command is issued to the reader.
While the command is running, users can switch between any of the three live views (Summary,
Standard and Protocol Trace). However, the user interface prevents users from switching to
any of the post-capture views. See the figure below.

Command Execution
Performing Post-Capture Processing
After one or more reader functions has completed, Tracer must perform the post-capture
processing to create the post-capture views. The post-capture processing builds an index of
the captured data which provides the data for the post-capture views.
You can perform the post processing by initiating it yourself or by configuring the application to
invoke it automatically. The procedure for each approach is described below:
z
To initiate the post processing (i.e., to build the indexed data file), select Build Post-Capture
Views as shown in the figure below. This option is enabled after the reader functions have
completed.
