µFR Device RF settings – reset to default

If the device does not have the appropriate RF settings,a hardware malfunction causes this problem. f this is the case with your device, we advise trying to reset the device RF parameters first.
First you need to download our Anti-Collision SDK, which also contains a set of functions for hardware RF sensitivity adjustments. This software description and manual is available at https://www.d-logic.net/nfc-rfid-reader-sdk/software/ufr-anti_collision_algorithm/.
 
1) The first group of commands applies to the hardware RF field setup.
 
Press the key 9 first, and write down your reader current settings.
Further, start changing the readers’ values one by one (as listed on the software menu), while moving the card up and down for every change. This way you will be able to detect the combination of the setting that gives the best result.
 
2) Alternatively, you can use our tool for automated RS settings, available on https://www.d-logic.net/code/nfc-rfid-reader-sdk/ufr-examples-rf_analog_setting.
