B+B SmartWorx 4 Port Ethernet Serial Server

The B+B SmartWorx ESR 4-Port Ethernet Serial Server is a rugged, reliable bridge that brings legacy serial devices into modern IP networks. Perfect for factory floors and control rooms, this device converts Ethernet to RS-232, RS-422, or RS-485, enabling seamless communication with PLCs, CNC machines, HMI panels, and other industrial equipment that still rely on traditional serial interfaces. With four independent ports, scalable deployment options, and industrial-grade construction, it simplifies integration, boosts data visibility, and supports efficient remote diagnostics and control across your LAN.

• Versatile four-port serial platform: Each of the four ports can be configured for RS-232, RS-422, or RS-485, allowing you to match the exact electrical and distance requirements of your devices without extra adapters or converters.
• Industrial Ethernet bridge for automation: By bridging your serial devices to the Ethernet network, you gain centralized monitoring, data logging, and remote access. This ESR supports network protocols commonly used in industrial environments, enabling smooth interaction with PLCs, CNCs, HMIs, and other equipment over TCP/IP, UDP, and Telnet sessions.
• Remote management and diagnostics made easy: A web-based configuration interface plus command-line options give you full control over port mappings, serial parameters, and network settings. Quick status indicators and diagnostic tools help identify issues before they impact production, reducing downtime and maintenance time.
• Rugged, flexible installation: Built for harsh industrial environments, the ESR is designed for easy mounting on DIN rails or wall surfaces in control cabinets, machine rooms, or field deployments. It’s compact, reliable, and engineered to withstand typical factory temperatures and vibrations.
• Future-ready integration for Industry 4.0: Turn legacy serial devices into network-enabled assets, enabling centralized data collection, remote operation, and enhanced production visibility across multiple locations. This makes it easier to implement SCADA, MES, or IoT strategies without replacing existing serial equipment.

How to Install B+B SmartWorx 4 Port Ethernet Serial Server

• Choose a secure, ventilated installation location in or near the equipment you’re integrating. Mount the ESR on a DIN rail or wall-mount it to fit your panel layout.
• Connect up to four serial devices to the ESR ports using appropriate cables configured for RS-232, RS-422, or RS-485. Ensure proper grounding and cable routing to avoid interference.
• Run an Ethernet cable from your network switch or router to the ESR’s LAN port. Verify the network path to your IT or OT network to ensure seamless data flow.
• Apply the correct DC power supply according to your SKU’s specifications. Confirm power stability to prevent interruptions during operation.
• Access the ESR’s web interface (or use RFC2217 clients) to configure port mappings, serial settings (baud rate, data bits, parity, stop bits, and flow control), and network options. Save the configuration, reboot if required, and test each port by communicating with the connected devices. Use built-in diagnostics to verify link status, error counters, and data throughput, then fine-tune as needed for optimal performance.
