Nordic ID FR22 User Guide
Version 1.0
THERMAL MANAGEMENT
Nordic ID FR22 reader includes sophisticated thermal management features that do prevent overheating
issues if reader is used in too warm environments. The reader monitors temperatures of onboard
computer and UHF RFID module and adjusts operation points based on the temperature information.
Onboard computer starts mitigation scheme (for example clock frequencies of CPUs are dropped) when
temperature of the onboard computer reaches 85°C.
Thermal mitigation scheme of the UHF RFID module starts when it reaches 80°C. From that moment on,
UHF RFID reading operations are suspended for 100ms and suspend time is increased 20ms by every °C
temperature rises. The thermal mitigation scheme is turned off once the temperature drops below 80°C.
High temperature warning message (TEMP_HIGH) is sent via NUR API to host. The warning message
contains also current temperature information.

NORDIC ID RFID DEMO
The Nordic ID RFID Demo application is used to perform RFID reading and writing tests. The application
provides statistics on the reading performance and logging capabilities for more thorough evaluation. It
is available for Microsoft Windows and Android OS.
This application also allows adjusting the RFID parameters on the fly for better understanding how they
impact on the reading performance. Note that altered settings cannot be stored permanently into the
device. The settings are reverted to defaults upon power cycle. For permanent settings, lease use the
Nordic ID RFID Configurator application
