    Why is my Dormakaba IP Access Controller remote reader reading data incorrectly?
    • R
      Robin BeltranAug 10, 2025
      Incorrect data reading by the remote reader in Dormakaba IP Access Controllers can occur due to several reasons. It could be due to an interruption in the registration unit's connection, which requires checking and repairing the connection. Alternatively, the RFID media technology may not be defined, necessitating its definition using a programming master. New interference sources, such as hubs or security systems, can also cause this issue; try increasing the distance or shielding. Cabling changes may also be the cause, so adjust the cabling accordingly. Finally, ensure users are correctly using the medium.
