Product Commonality

Protection Of Industry

Adopts industrial design, 7*24 hours high load all weather reliable work, to meet the outdoor poor working environment needs.
Support level 4 ESD (static), level 3 surge (surge), level 3 EFT (electrical fast transient), internal process watchdog, and external hardware watchdog to ensure proper operation of equipment and free from interference from external environment.

Transparent Transmission

Two-way data transmission between RS232/485/422 and Ethernet can be realized. That is, the Cellular Modems can convert the original data of the serial port into TCP/IP packets for transmission without changing the original data communication content. As a result, the DTU can be connected to various user devices using serial communication without modifying the user devices.

Remote FOTA Upgrade

With the remote management platform,it can realize the automatic firmware upgrade.
The difference algorithm upgrade package is small,saving upgrade traffic and time.

Quality Assurance

For 10 years of advance, we have always been remaining true to the concept of reliability and stability in building our quality strength. Our products have passed the certification of the ISO9001 quality management system. With nearly 100 patents and software copyrights, we have won many certificates from authoritative bodies, such as network access licenses of the Ministry of Industry and Information Technology, CCC,CE,FCC,RoHS,KCC,WEEE,TELEC,IC and SRRC.

Modbus Transmission

Modbus protocol adopts the mode of master station query slave station. The physical interface can be RS232, RS485, RS422, Rj45, and can also transmit data on various media.
The Modbus polling mechanism can effectively solve the problem of sticky congestion caused by data concurrency.

Industrial Protection

Adopts industrial design, 7*24 hours high load all weather reliable work, to meet the outdoor poor working environment needs.
supports Level 4 ESD (Static), level 3 Surge (Surge),level 3 EFT(Electrical Fast Transients),internal process watchdog and external hardware watchdog, to ensure normal operation of the equipment and immunity from the outside environment interference.

Solutions & Applications

Agricultural Water-saving Irrigation Solution Adopting measures suiting local conditions, the agricultural water-saving irrigation system uses different irrigation facilities according to the needs of different regions and crops.

Remote intelligent meter reading In nowadays, the large number of various meters are dispersed in different locations, some of which are remote and difficult to access, a remote meter reading system is urgently needed to relieve staff of utilities from heavy but inefficient tasks.Traditionally, the utilities companies used to hire thousands of meter readers to go around to read the meter, and always spend much money on traffic and labor.
