Nordic ID EXA31 has three physical buttons for user interactions. Location of the buttons can be seen in picture.



Trigger button


The trigger button is located at the top of the reader. It can be used to start/stop UHF RFID/barcode scanning and turn the reader on. When turning the reader on the trigger button needs to be pressed 0.5 seconds until blue LED starts blinking before it triggers. This ensures that accidental presses are avoided. Depending on the application in use, the trigger button starts/stops UHF RFID or barcode reading. By default, the first press of the button starts the reading and the second press of the button stops it.

NOTE! Button usage depends on the application in use.



Power button


Power button turns reader On/Off. The power button needs to be pressed for about 2…3 seconds until red LED turns to green before it triggers, this ensures that accidental presses are avoided. The power button is disabled when Nordic ID EXA31 has an active Bluetooth connection with the host device.

NOTE! Reader can be powered down even though it has an active Bluetooth connection by pressing power button down at least 7 seconds



Unpair a bluetooth device button


If Nordic ID EXA31 is paired to the host device, it stores information about the paired devices and tries to connect automatically when turned on. Using the “Unpair a Bluetooth device” button clears the paired device from the memory of Nordic ID EXA31.

Unpairing:

  • Make sure device is disconnected.
  • Press and keep “Unpair” button down at least 3 second.
  • When device beeps three times, pairing is cleared. Device may reboot.
NOTE! The “Unpair a Bluetooth device” button is disabled when the Nordic ID EXA31 has an active Bluetooth connection with host device
