    Data Transfer Unit

    Data transfer unit is abbreviated as DTU, is a wireless data acquisition device specially used to convert serial port data to IP data or convert IP data to serial port data. It is transmitted through a wireless communication network. Data transfer unit uses advanced ultra-narrowband modulation technology, which greatly improves communication distance and transmission stability. ATO has a variety of DTU models for selection, adapts to Modbus protocol, supports RS485 and RS232 communication interfaces, max transmission distance can be up to 20km. Some specific models use LoRa modulation technology, making DTU has strong diffraction and penetration, meeting a variety of data transmission needs.
