Product Description

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.
