GeneralGeneralGeneralGeneralSignshine S3321 GPRS DTU is a kind of cellular terminal device with RS232/RS485 that provides data transfer

function by public GPRS network

It adopts high-powered ARM9 CPU and embedded real time operating system, integrates all the commonly used

protocols, such as TCP/IP/UDP and so on, from logical link layer to upper application layer protocols. It provides a

secure, high speed, reliable wireless internet connection for customers and supports several ways that trigger DTU to be

online, including SMS and data. It also supports double or several data centers.

This product has been widely used in M2M/SCADA field,such as power automation, transportation, financial service

terminal, factory automation, water, oil&gas, large machine maintenance, environment, building automation, outdoor

digital signage ect.
