A low-power, cellular-based solution for serial to Ethernet conversion

In today's rapidly advancing technological landscape, the need for efficient and reliable communication within industrial networks is more crucial than ever. Serial device servers bridge the gap between legacy serial devices and modern communication protocols, enabling seamless connectivity and data exchange between serial devices and Ethernet networks. By transforming serial data from devices such as PLCs, sensors, and meters into TCP/IP packets that can be transmitted over Ethernet networks, serial servers and protocol gateways allow real-time monitoring, remote control, and centralized management of diverse devices dispersed throughout industrial environments. They ensure seamless integration with modern SCADA (Supervisory Control and Data Acquisition) systems, enhancing overall operational efficiency.

The ATOP SE5201B Serial to Cellular Gateway stands out as  an innovative solution designed to meet the evolving needs of industrial networking. One of the key advantages of SE5201B is its cellular gateway capability. By incorporating LTE Cat-1 connectivity, the device enables fast and seamless communication over long distances, eliminating the constraints of physical cabling and extending network coverage to remote and challenging locations. This feature is particularly valuable for applications such as remote monitoring of oil and gas pipelines, wind farms, and unmanned substations, where establishing traditional wired connections can be impractical or costly.

Energy efficiency is another important issue in large-scale industrial sites. Leveraging the extended idle and sleep modes of Cellular LTE Cat-1, power consumption of SE5201B can be less than 100 mW. Thus, it conserves power for necessary operations. This feature also allows applications where power supply is a limiting factor, such as when using solar power.


On the other hand, a built-in SD slot offers scalable storage for operational performance. Besides accommodating bigger files and larger amounts of data, it enables easy firmware updates and configuration backups, as well as data exchange and transfer, increasing work efficiency and flexibility.

Security measures are essential in industrial environments, where the integrity and confidentiality of operational data are paramount. The SE5201B Serial Server boasts advanced security features, like SSL/TLS encryption, integrated firewall, zone forwarding, and VPN. Especially with wireless connections, enhanced cybersecurity ensures data integrity and protection against unauthorized access.

With its industrial-grade design, SE5201B ensures reliable performance even in harsh environments characterized by extreme temperatures, humidity, and vibrations. As the world continues to embrace digital transformation, we provide a valuable tool for optimizing operations, increasing productivity, and enabling remote monitoring and control in a wide range of industrial applications, including manufacturing, energy, transportation, and critical infrastructure. While this latest model focuses on serial data through RS-232/RS-485, gateways supporting Modbus, DNP3, and other industry-specific protocols are also coming soon.
