MNT351 NB-iot DTU produced by Maiwe. It is a wireless data transmission terminal device that supports mobile, China Unicom and China Telecom NB-IOT networks, realizing the two-way transmission function of RS232/422/485 into NB-IOT. It supports NB-IOT serial port transmission, global mainstream frequency bandwith good network compatibility. Providing TCP/IP network protocol wireless data transmission channel to industrial users which can provide full transparent data channel. It can realize the bidirectional data transparent transmission of serial port to the network to achieve the field RS485/RS232/RS422 bus equipment and the central control system of wireless data communication.
-The embedded NB-IoT DTU in the high-performance industrial communication field is compatible with the RS485/RS232/RS422 bus in the industrial field to meet the diverse needs of users;
-Support the host computer to configure/query device parameters through the serial port AT command;
-Support configuration/inquiry of device parameters through Maiwe cloud platform;
-Support TCP Client, UDP Client;
-Support 2 Socket connections;
-Support heartbeat package and registration package functions, the types are ICCID, IMEI, user-defined data, etc., and support the automatic reconnection function when the network is disconnected;
-Support transparent transmission, Maiwe cloud communication protocol, Ali MQTT, China Mobile OnetNet MQTT protocol;
-The external independent hardware watchdog design prevents crashes; the PSM function meets the needs of users for low power consumption.
