Its main functions include real-time lock status monitoring, anti-tamper alert, anti-cut alert, swiping an RFID card to lock or unlock the device, and super long standby time. There is no button on the outer case of the device, and the IP67 water resistance rating makes the device withstand harsh environments ,and the device also has a crash-proof housing design. It is specially designed for door lock management in various land and sea transportation such as box trucks, trailers and containers. 2.1 Product Features 2.1.1 LoRa Communication (Optional) This function is used for communication between the K211L and the T399G vehicle tracker. After the LoRa connection is successful, the K211L will send information such as lock status information and battery power to the T399G via LoRa. To establish LoRa communication between the K211L and the T399G, the two devices must be bound each other. For details about how to bind the T399G to the K211L, see the section 6.5 "Binding or Unbinding the T399G." LoRa connection process: Start the two devices and connect them to a PC. Start Meitrack Manager and bind the T399G. The LoRa connection will be established automatically after the two devices are bound. The LoRa connection is established successfully if the LVS LED indicator blinks. T399G and K211L communication features: The K211L can be connected to the T399G via LoRa to upload data. One T399G tracker can be connected to at most 30 K211L devices at the same time.

LoRa Deep sleep mode (send heartbeat After the K211L is started properly, if no event is triggered, disconnected packets once every one hour) the K211L will enter the deep sleep mode (the GPS module will stop) after five minutes (default time). The wakeup conditions include vibration, swiping RFID cards ,Call ,SMS and sending heartbeat packets. Super deep sleep mode (send After the K211L is started properly, if no event is triggered, heartbeat packets once every one the K211L will enter the deep sleep mode the GPS and GSM hour) module will stop) after five minutes (default time). The wakeup conditions include vibration, swiping RFID cards and sending heartbeat packets. Sleep mode disabled Report data at the preset interval. 2.1.2 Locking or Unlocking the K211L Locking or Unlocking by Swiping RFID Cards Copyright © 2022 Meitrack Group All rights reserved. - 5 - MEITRACK K211L GPS Smart Lock User Guide 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 twicebut 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 performanceand 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. Locking or Unlocking by Commands Command Description How to Send D82 This command is used to lock or Send the command by SMS or GPRS. For details about unlock the K211L. the SMS command format, see the section 6.6.8 "Locking or Unlocking the K211L D82." D83 This command is used to select a Send the command by SMS or GPRS.
