2Product Introduction
The K211G 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. 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 K211G and the T399G vehicle tracker. After the LoRa
connection is successful, the K211G will send information such as lock status information and battery power to the
T399G via LoRa. To establish LoRa communication between the K211G and the T399G, the two devices must be
bound each other. For details about how to bind the T399G to the K211G, see the section 6.5 "Binding or Unbinding
the T399G."
LoRa connection process:
T399G and K211G communication features:
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.
The K211G can be connected to the
T399G via LoRa to upload data.
One T399G tracker can be connected
to at most 30 K211G devices at the
same time.

Communication diagram
K211G Working Mode Status
LoRa connected The GPS and GSM modules of the K211G enter the sleep
mode, and 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 K211G is started properly, if no event is triggered,
the K211G will enter the deep sleep mode 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 K211G
Locking or Unlocking by Swiping RFID Cards
The function is used to lock or unlock the K211G by swiping authorized RFID cards. When you swipe an RFID card,
the K211G 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 K211G's card swiping area. When the K211G detects this
action, the buzzer will beep and the LVS LED indicator will be steady on, indicating that the K211G is unlocked. In this
way, the last step for you is to pull out the lock rope. (To lock the K211G, 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 K211G 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. If you
swipe an authorized RFID card, the buzzer will beep once. After the K211G is unlocked, if you do not pull out the lock
rope within one minute, the K211G will be locked automatically.

2.1.3 Dual SIM Cards
The K211G 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.)
