The function is used to lock or unlock the K211L by swiping authorized RFID cards. When you swipe an RFID card, the
K211L will automatically detect and record the unlocking time, location and RFID card number, and these data will
be sent to the server.
Operation process: Put the authorized RFID card on the K211L's card swiping area. When the K211L detects this
action, the buzzer will beep and the LVS LED indicator will be steady on, indicating that the K211L is unlocked. In this
way, the last step for you is to pull out the lock rope. (To lock the K211L, you only need to swipe the RFID card once.
Then the buzzer will beep and the LVS LED indicator will be off, indicating that the K211L is locked.)
Swiping an RFID card:
Note: In the locking or unlocking state, if you swipe an unauthorized RFID card, the buzzer will beep twice
，
but the
K211L cannot be unlocked and locked. If you swipe an authorized RFID card, the buzzer will beep once. Before the
K211L is locked,it is recommended to apply appropriate force on the lock rope first to make the waterproof ring of
cable fully contact with the lock hole and improve the waterproof performance
，
and if the lock rope is cut, K211L
cannot be locked. After the K211L is unlocked, if you do not pull out the lock rope within one minute, the K211L will
be locked automatically.
