Industrial CDMA DTU 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 CDMA RS232 RS485 DTU has been widely used in M2M/SCADA field,such as power automation, transportation,
financial service terminal, factory automation, water, oil&gas, large machine maintenance,
