The SeDTU200 series data terminal unit is an industrial wireless data
terminal product that leverages LTE 4G wireless networks to provide a reliable wireless
data transmission channel over TCP/IP for industrial users. It enables seamless wireless
data communication between serial devices at remote control stations and central
control systems, facilitating remote industrial field control. Equipped with a high-performance industrial-grade MCU main control chip and an
embedded real-time operating system, the SeDTU200 ensures stable and reliable
operation. It supports RS-232 and RS-485 interfaces for direct connection to serial
devices, enabling transparent data transmission. The device offers multiple
configuration and management methods, including local PC-based tools, AT
command configuration, and TCP/IP remote configuration. This simplifies on-site
installation and post-maintenance, significantly improves deployment efficiency, and
reduces overall system operational costs, allowing users to fully experience the
convenience of wireless communication.
