Engineered for high-reliability industrial environments
The Evolution of RS232 Over IP and Protocol Conversion in Industry 4.0
In the rapidly evolving landscape of Industrial Internet of Things (IIoT), the bridge between legacy serial communication (RS232/RS485) and modern IP networks has never been more vital. While wireless standards advance, the robustness and reliability of wired RS232/485 protocols remain the backbone of global oil, gas, and manufacturing sectors. RS232 Over IP technology enables these legacy devices to be managed, monitored, and integrated into cloud-based SCADA systems without requiring expensive hardware overhauls.
The global market for serial-to-Ethernet converters is shifting from simple "transparent transmission" to Edge Intelligence. Modern factories no longer just move data; they process it at the gateway.
Expertise in HART, MODBUS, and GPRS protocols, ensuring seamless integration between field instruments and control centers.
High-speed ARM processors ensure ultra-low latency in RS232/485 to TCP/IP conversion, critical for safety systems.
Designed for extreme temperatures and electromagnetic interference, meeting stringent factory floor requirements.
The Songmao Advantage in Jiaxing's Electronics Hub
China has become the global epicenter for industrial communication hardware. Located in Jiaxing, Jiaxing Songmao Electronics Co., Ltd. leverages a highly specialized supply chain that offers unique advantages:
Application Scenarios for Global Enterprises
Utilizing HART-to-Modbus TCP gateways to monitor pressure and flow sensors in remote wells via 4G/GPRS networks.
Interconnecting multivariable converters to optimize thermal efficiency across metropolitan heating grids.
Collecting 4-20mA signals from water quality sensors and converting them to RS485 for centralized management.
SONGMAO Electronic Co., Ltd. (Jiaxing Songmao Electronics Co., Ltd.) was established in 2007. It has always been driven by technological innovation, deeply engaged in the field of industrial automation, and gradually developed into a high-tech enterprise integrating R&D, production and sales.
The company focuses on the independent research and development of core technologies such as HART protocol communication products and data collectors. Through continuous technological breakthroughs and market expansion, it has established a leading position in the industry.
Meeting the Demands of Modern Supply Chains
Global procurement managers face the challenge of balancing reliability, compatibility, and cost. Our RS232 over IP solutions address these through:
RS232 is designed for point-to-point communication over short distances, while RS485 supports multi-drop networks and longer distances. Our converters often support both, allowing serial data to be encapsulated into TCP/IP packets for transmission over Ethernet or the Internet.
Devices like the SM100-B read the digital HART signal superimposed on the 4-20mA analog loop and translate that data into Modbus registers. This allows PLC/DCS systems that only support Modbus to read complex process variables from HART-enabled instruments.
Yes. Our SM626H-A series uses cellular networks (All-Netcom 4G) to transmit data from field instruments directly to a central server or cloud platform, making it ideal for remote oil fields or environmental monitoring stations.
As a direct manufacturer, we provide comprehensive manuals and dedicated technical support to help you configure Baud rates, IP settings, and protocol mapping (e.g., Modbus RTU to TCP).
