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 >
< Flexible Data Packet Format Customization >
< 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
