Note: If the environmental resonances (if any) can be identified and physically removed, then the RX Gain
can be set higher for better detection.
Note: The TR4215 board exhibits some natural internal resonance around 8 MHz which does not need to be
tuned out. Because the signal is internal and the fact the Analog View is now multiplied by 2, the
typical tuning should look like the figure 46.
Jammer Indication
Recently our customers have become concerned about different jammer devices blinding our
systems by reducing detection and allowing tagged merchandise to become undetectable. For this
reason a jammer indication feature was created to allow the customer to track these devices.
The Jammer Indication feature is enabled when the Jammer Threshold switch is set to anything
other than 0. However, a limitation of the feature is false indications when a sweeper is in close
proximally. It becomes obvious after enabling the feature. If present, the feature cannot be used.
In a clean environment, the Jammer Threshold is typically set for 11 (for both master and
submaster antennas).
Data Retrieval
TR4215 functionality allows the CSE to access and retrieve data stored internally.
Event History
The only way to retrieve data from a TR4215 board is to connect to the serial port (J48) using the
DMS tool. Using the DMS application, display the Event History and (optionally) save the event
history as a .csv file. Change the file extension to “.csv” so it is saved in CSV format.
For complete details on accessing the Event History, refer to the Field Service Diagnostic
Management User’s Guide.
Snap Shot feature
For detailed information about using the DMS tool to access the Event History and obtain a
snapshot view of the selected alarm (from the last 10 alarm events), also refer to the guide.
