DR301 is a compact RS232 to Ethernet converter that provides bidirectional transparent transmission between RS232 devices and Ethernet networks. Key benefits Reliable bidirectional bridging: seamless communication between RS232 equipment and Ethernet networks without protocol changes. Modbus gateway support: enables integration of RS232 devices into Modbus TCP/Modbus gateway configurations. Space saving and easy setup: DINrail mountable in a compact footprint for tidy, scalable deployments. Virtual serial port compatibility: PC software that expects a serial port can communicate with networked devices through the DR301. Why you need it Integrate legacy serial equipment into modern Ethernetbased control and monitoring systems. Extend reach of RS232 devices by accessing them over a local network or remote connections. Simplify software integration by providing a virtual serial interface for applications that cannot directly address networked hardware. What makes it stand out Small size with DINrail mounting for efficient, secure installation in industrial environments. Direct RS232 to Ethernet transparent transmission, maintaining compatibility with existing serial protocols. Builtin Modbus gateway capability broadens connectivity options to industrial protocols and networked architectures. Virtual serial software feature simplifies PCside communication with networked devices, reducing the need for custom drivers or complex reconfigurations. Applications and use scenarios Industrial automation: connect legacy RS232 sensors and controllers to an Ethernet LAN for centralized monitoring and control. Remote device management: access serial equipment over the network for diagnostics, maintenance, and maintenance windows without onsite visits. Modbus integration: bridge RS232 Modbus devices to a Modbus TCP network, enabling unified supervision and data collection.
