Product Introduction

The K211L is a GPS smart lock that supports Long Range (LoRa) and GPRS communication. 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 to each other. For details about how to bind the T399G to the K211L, see section 6.5 “Binding or Unbinding the T399G.” Lora connection process:

Communication diagram

its lock status information and alerts will be uploaded to the server through the T399G.
Lora disconnected| Deep sleep mode (send heartbeat packets once every one hour)| After the K211L is started properly, if no event is triggered, 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, calls, SMS, and sending heartbeat packets.
Super deep sleep mode (send heartbeat packets once every one hour)| After the K211L is started properly if no event is triggered, the K211L will enter the deep sleep mode the GPS and GSM 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 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, 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 in 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.

Locking or Unlocking by Commands

SMS or GPRS. For details about the SMS command format, see section 6.6.8 “Locking or Unlocking the K211L – D82.”
D83| This command is used to select a locking method: auto locking or locking by swiping RFID cards.| Send the command by SMS or GPRS. For details about the SMS command format, see section 6.6.9“Selecting a Locking Method – D83.”

2.1.3 Dual SIM Cards
The K211L can be installed with two Micro SIM cards and supports the dual SIM single standby mode. The device will automatically select a SIM card to register the network. SIM1 (on the right) will be selected by default. If SIM1 fails to register the network, SIM2 (on the left) will be selected to do this. (Please ensure that at least one SIM card can
be used normally.)

2.1.4 Magnetic Charging
You can use the magnetic charging cable to charge the K211L. The device supports 9V/2A power adapter, and it will take a total of 7.5–8 hours to charge the device fully.

2.1.5 Strong Magnetic Adsorption
The back of the cover plate has strong magnetic, which can be adsorbed to the car door to prevent the device from shaking during movement.

2.1.6 Anti-collision Soft Adhesive
The gray protruding part in the figure is an Anti-collision soft adhesive, which has a shock absorption effect and it can effectively protect the device from being damaged in the collision.

2.1.7 Security Performance – Super Password
To enhance security, K211L supports super passwords.
Super password (the default is 666888) supports all SMS commands, but DB0 / D82 / D10 / D11 / D14 D15 / A21 / F22 commands can’t use the original SMS password (the default is 0000), they can only use a super password. When setting GPRS parameters through Meitrack Manager, you need to open the super password first before setting them successfully:

Note ：
It is recommended to set a new super password first because the super password is related to the security of unlocking; The default super password is 666888, which can be modified by Meitrack Manager and the F22 command. Please make sure to remember the super password, and the super password cannot be quested and reset to the original value, once you forget the password, it will not be able to recover.

6.6.2 Setting a Smart Sleep Mode – A73

When the sleep level is 1, the tracker enters the normal sleep mode. The GSM module always works, and the GPS module occasionally enters sleep mode. The tracker works 25% longer in the normal sleep mode than that in the normal working mode. This mode is not recommended for short-interval tracking; this will affect the route precision.
When the sleep level is 2, the tracker enters deep sleep mode. If no event (RFID, shear line, vibration, incoming calls, or SMS) is triggered after five minutes, the GPS module will stop and the GSM module will enter sleep mode. Once an event is triggered, the GPS and GSM modules will be woken up. When the sleep level is 3, the tracker enters deep sleep mode. If no event (RFID, shear line， vibration) is triggered after five minutes, the GPS and GSM module will stop. Once an event is triggered, the GPS and GSM modules will be woken up.
