factory reset mode. This mode can be entered within 5s after the CONNECTION LED
has turned on.
* Recovery mode can be used to repair the reader
1.10. RF PROFILES
Nordic ID NUR2-1W UHF RFID module supports three different kind of RF profiles. The profiles are
Robust, Nominal and High speed. It’s important to select the correct RF profile based on use case and
environment. More detailed description about the RF profiles can be found below:
•Robust
oRobust RF profile is intended to be used in challenging environments. It provides the best
filtering against the interfering signals coming from nearby reader(s), other signal sources
and from reflective environment. This profile uses link frequency of 250 kHz and Miller
4 coding scheme providing read rates up to 200 tags/s. Due to the low data speed and
best filtering the Robust RF profile provides the best sensitivity.
•Nominal
oNominal RF-profile is the default setting of readers containing Nordic ID NUR2-1W UHF
RFID module. It uses link frequency of 300 kHz and Miller 2 coding providing read rates
up to 350 tags/s.
•High speed
oHigh speed RF profile is intended to be used in use cases where the highest read rates
are required. It uses link frequency of 400 kHz and FM0 coding and provides read rates
up to 1000 tags/s. Due to the high data speed the profile is quite sensitive to
interferences.
1.11. THERMAL MANAGEMENT
NOTE! If reset button is pressed over 5s after the CONNECTION LED has turned on and the red
INDICATION LED has started blinking even faster, releasing the reset button will perform a
normal reboot.
NOTE! Read rates will depend from the environment, reader settings, tag population and tag type.

Nordic ID AR82 User Guide
Version 1.2
Nordic ID AR82 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 follows following temperatures:
•80°C – UHF RFID reading operations are suspended for 100ms. Suspend time is increased 20ms
by every °C temperature rises until the temperature reaches 90°C. 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.
•90°C – UHF RFID reading operations are shut down until temperature goes below 90°C. Once
the temperature is below 90°C, above mentioned mitigation scheme is taken in use. Over
temperature warning message (TEMP_OVER) is sent via NUR API to host. The warning message
contains current temperature information.

SOFTWARE
All documentation about SW, SW features and application development can be find from GitHub.

2.1. NORDIC ID RFID APPLICATIONS FOR NORDIC ID AR82
Nordic ID provides following Windows tools to test and configure the reader. The tools are available via
Nordic ID Support pages:
http://www.nordicid.com/en/downloads/
NORDIC ID RFID DEMO
Nordic ID RFID Demo application is for conducting the reading tests. It allows connecting the devices and
commencing the reading procedure. The application provides statistics on the reading performance and
logging capabilities for more thorough evaluation. As the Nordic ID RFID Configurator, this application
also allows adjusting the RFID parameters on the fly for better understanding how they impact on the
reading performance. The difference however is that altered settings cannot be stored permanently into
the device. The settings are reverted to defaults upon power cycle.
NORDIC ID RFID CONFIGURATOR
Nordic ID RFID Configurator is meant for configuring the reader settings. The settings can be e.g. related
to network settings or RFID reading parameters and stored into the device as new defaults. Note that
e.g. the RFID reading parameters can be assigned to the reader by the host application after successfully
connected to the device also. The RFID Configurator is also the tool for updating the device firmware if
seen necessary.
NORDIC ID APPLICATION SIGNING TOOL
To provide more security to the SW platform, the application zip-files need to be signed with Nordic ID
provided signing tool. The public key generated to the zip-file will be then verified against the list of files
when installing the zip-file to the reader. This makes sure that only valid content from the zip-file can be
installed.
The tool in question is called Nordic ID Application Signing Tool. The tool can be used to sign pre-built
zip-files, as also to create new zip-files from scratch.
WEB MANAGEMENT INTERFACE
Nordic ID AR82 includes a web management interface which can be accessed with a web browser. The
web management interface is used to configure the reader and manage applications. Documentation
about web management interface can be find from GitHub.
https://github.com/NordicID/ar8x_samples
NOTE! Web management interface cannot be accessed using USB connectors. Web management
interface can be accessed only using ethernet, WLAN and WWAN connections.

REGIONAL SETTINGS
Nordic ID UHF RFID readers support operating frequency range between 860 - 960MHz. Some of the
readers cover full operating frequency band and some of them have two sub bands that are 868 ETSI
band (865.6 - 86 .6 MHz) and 915 FCC band (902 - 928 MHz). Regional organizations as ETSI and FCC
have set rules and requirements for operating frequencies, output power and other RF parameters for
the UHF RFID readers to comply local regional requirements.
Nordic ID has created a set of regional settings in order to fulfil local regulations. Nordic ID is required to
ensure that compliance of Nordic ID products will remain after production. Solution for this is that
products including UHF RFID functionality are set and locked in production based on customer order e.g.
if a product is ordered to Europe, it will be locked to ETSI region. And, if a product is ordered to Australia
region, it is locked to Australia region. When a product is locked to individual region, it will comply local
regulations of the region.
