Introduction

DTU (Data Transfer Unit) is a wireless terminal device used to convert serial data into IP data or IP data to serial data through wireless communication network. DTU is widely used in meteorology, hydrology and water conservancy, geology, smart grid, intelligent transportation, smart home, finance, mobile POS terminal, supply chain automation, industrial automation, intelligent building, fire protection, public safety, environmental protection, meteorology, digital medical treatment, remote sensing survey, military, space exploration, agriculture, forestry Industry, water, coal, petrochemical and other fields. 

The SLK-M200D LTE DTUs adopts highly integrated, highly reliable LTE communication modules and low power industrial CPU. At the same time, the standard RS232 and RS485 interfaces are provided for users to choose to solve the interface compatibility problems in different communication environments. The two serial ports possess the industrial protection requirements of ESD, TVS, FUSE and so on. In addition, according to actual needs, we need to choose products that need three standards. Wide voltage design supports DV6-28V to meet the power supply needs of most industrial environments.
