Main Function Description

Multiple Networks Online Mode

Support automatic switching in the online,IDLE,PSM modes to achieve low power. The time value of below image(20s,10s,24h) depends on the base station/core network of network operator, so are the mentioned power consumption value, users are better to get the values after practical testing.



NB-IoT Network Transparent Transmission Mode

Analyze and process various situations automatically, provide stable,reliable NB-IoT network transparent transmission access.



Quick Self-built Center

Using our SDK makes master computer development simpler, we can provide multiple language’s development routine, so you can also quickly establish your own center even without programming.


< Support Multiple Ways Of Parameter Configuration >

  • By using supporting software for parameter configuration
  • By integrating parameter configuration protocol for user motherboard
  • By integrating parameter configuration protocol for data center to remote configuration
  • By using virtual serial port and combine with local configuration software based on our cloud server


< Flexible Data Packet Format Customization >

  • Custom registration packet: Users can freely configure the content of the data packet sent when MDN211 is first connected to the data center 
  • Custom heartbeat packet: Users can freely configure the content of the heartbeat packet sent by MDN211 to the data center
  • Custom header packet: User can configure specific content before the data packet sent by the DTU to the data center in order to distinguish the data type or category


< Fully support Mind IoT >

Support Mind IoT Cloud without building server by users,user can use our Cloud transparent transmission technology without the fee of server so that reduce cost.




< Full support for industrial SCADA >

Support OPC Sever,multiple mainstream SCADA,virtual serial,reduce the difficulty of software development


< TTL Serial port Communication >

Baud can be chosen from 1200bps to 38400bps,data bits/stop bits/parity can be optional


< SIM Interface >

The user can design the location of the SIM card by himself to reduce the difficulty of use by customers


< Small Volume >

small volume, 28mm*44mm*8mm,more suitable for embedded integration
