Gateway + DTU two-in-one solution

communication device that integrates DTU (Data Transmission Unit) functionality. It is specifically designed for industrial automation, remote monitoring, and IoT applications. Its DTU capabilities provide users with efficient and stable data acquisition and remote transparent transmission, making it widely applicable in industries such as power, environmental protection, energy, and transportation.

▶ Core DTU Functions

Transparent Conversion between Serial and IP Data

WIS901 supports common serial interfaces such as RS232/RS485. It can convert serial data from field devices (like PLCs, instruments, sensors, etc.) into IP data in real time, transmitting it remotely to data centers or cloud platforms via the 4G wireless network. Conversely, it can also forward IP data to field devices, enabling bidirectional transparent data transmission.

Built-in TCP/IP Protocol Stack and PPP Dial-up

The device features a complete TCP/IP protocol stack and PPP dial-up functionality. Upon power-up, it automatically registers with the 4G network and establishes a SOCKET connection with the server, supporting both TCP and UDP communication modes to meet various application requirements.

Automatic Heartbeat and Always-Online

WIS901 includes an automatic heartbeat mechanism, sending heartbeat data when there is no communication for an extended period to maintain a persistent connection with the server. It also supports automatic reconnection and redialing, ensuring high availability of the data link.

Parameter Configuration and Permanent Storage

The gateway allows flexible configuration of parameters such as server IP, port, and serial baud rate, and can permanently save these settings in internal memory (such as FLASH). After powering on, the device operates according to the preset parameters, eliminating the need for repeated configuration.

▶ Application Advantages

Plug-and-Play, Flexible Networking

Supports plug-and-play SIM cards and flexible networking, suitable for diverse industrial sites and distributed remote scenarios.

High Stability and Security

Industrial-grade hardware design ensures reliable data transmission even in harsh environments. The device also supports essential data encryption and access control to enhance system security.

Wide Industry Applicability

Suitable for applications such as power meter reading, environmental monitoring, remote management of charging stations, hydrology and water conservancy, and industrial automation.

▶ Summary

By integrating DTU functionality, the WIS901 4G industrial gateway enables transparent, efficient, and secure data transmission between field devices and remote centers. Whether for data acquisition, monitoring, or remote control, WIS901 provides users with stable and reliable communication, making it an ideal choice for modern industrial IoT applications.
