Keys and Buttons



The Nordic ID EXA51e includes two capacitive buttons and one physical button for user interactions. Location of the keys can be seen in the picture




Trigger button



The trigger button is located on the pistol grip and it can be used to start/stop UHF RFID/barcode scanning and turn 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.





Power key



Power key turns reader On/Off. The power key 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 key is disabled when Nordic ID EXA51e has an active Bluetooth connection with 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 key



If the Nordic ID EXA51e 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” key clears paired device from the Nordic ID EXA51e memory.



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” key is disabled when Nordic ID EXA51e has an active Bluetooth connection with host device
