B+B SmartWorx 1 Port Ethernet Serial Server, DIN, Wide Temperature

Designed for industrial environments, the B+B SmartWorx ESR 1-Port Ethernet Serial Server bridges Ethernet networks with legacy serial devices. It supports RS-232, RS-422, and RS-485, enabling seamless communication between PLCs, CNC machines, HMI panels, and other equipment and the LAN. With DIN-rail mounting, rugged construction, and wide-temperature operation, this compact gateway helps you modernize old equipment, enable remote management, and collect data across the factory floor without rewriting existing control logic. Whether you’re upgrading a single station or integrating multiple devices into a unified SCADA or MES system, this 1-port Ethernet serial server provides a reliable, scalable solution that reduces downtime and improves data visibility across your industrial network.

• Flexible serial port compatibility: RS-232, RS-422, and RS-485 are supported and configurable, enabling seamless connection to a broad range of devices. Auto-detection or manual mode selection lets you tailor the gateway to your exact serial topology, whether you’re linking a single PLC input or coordinating a multi-device serial network. This versatility makes it ideal for retrofitting legacy equipment into modern Ethernet architectures, allowing disparate machines to share data in real time. The ESR’s serial versatility also simplifies upgrades, maintenance, and future integrations, all while preserving existing control logic and device interfaces.
• Robust LAN integration for industrial networks: A dedicated Ethernet interface provides reliable LAN connectivity with straightforward port mapping, static IP or DHCP support, and efficient data bridging between serial devices and network hosts. You can route serial data to fixed destinations, broadcast to multiple endpoints, or create point-to-point tunnels for high-priority telemetry. This LAN bridging capability enables seamless integration with SCADA, HMI, MES, and cloud-based monitoring systems, helping you gain real-time visibility and actionable insights without disrupting operations on the shop floor.
• Durable, factory-ready design: The ESR is built for harsh environments with DIN-rail mounting for quick panel integration, compact footprint to fit crowded electrical enclosures, and a wide operating temperature range to handle temperature swings common in manufacturing. Its rugged construction, coupled with EMI/RFI protection and solid connector interfaces, ensures reliable operation amid dust, humidity, and electrical noise. This resilience translates to fewer field failures, lower maintenance costs, and higher uptime for critical control and automation systems.
• Easy configuration and maintenance: The gateway features a user-friendly configuration interface—via web UI and optional CLI—for rapid setup, monitoring, and adjustments. You’ll find straightforward mapping of serial data to Ethernet sockets or virtual ports, simple baud rate and framing parameter settings, and clear status indicators for quick fault finding. Built-in diagnostics, event logs, and firmware update options help minimize downtime, while password protection and access controls reinforce security for remote management over the network.
• Wide range of industrial use cases: Use cases span PLC interfacing, CNC machine data extraction, HMI retrofits, remote sensor connections, and integration with SCADA or MES platforms. The ESR acts as a reliable gateway that transforms legacy serial streams into Ethernet-friendly data so operators, engineers, and IT teams can monitor, log, and control production processes from central dashboards. Its versatility supports data logging, remote troubleshooting, predictive maintenance, and scalable expansion as your automation needs grow.

How to install B+B SmartWorx 1-Port Ethernet Serial Server, DIN Rail, Wide Temperature

• Prepare the installation site: select a clean, ventilated panel area with adequate clearance around the device and accessible cabling pathways. Ensure the DIN-rail is securely mounted and grounded according to local electrical standards.
• Mount the ESR on DIN rail: hang the unit onto the DIN rail and snap it into place, verifying a snug fit that resists vibration and movement in an operating environment.
• Connect the serial device: attach the RS-232, RS-422, or RS-485 cable from your PLC, CNC, or HMI to the ESR’s serial port. Use shielded cables where possible to minimize noise pickup; ensure proper termination for RS-485 networks if required.
• Connect the Ethernet network: plug a standard Ethernet cable from the ESR’s LAN port to your switch, router, or network hub. Verify link activity and ensure the device is reachable on the local network.
• Power and initial configuration: supply DC power within the device’s specified range and confirm power indicators. Access the built-in web UI or CLI to configure network settings (IP address, gateway, and subnet), serial parameters (baud rate, data bits, parity, stop bits), and the data routing rules between serial data and network destinations.
• Test and validate: perform end-to-end testing by sending data from the serial device and confirming reception on the networked host, and vice versa. Adjust settings as needed to ensure data integrity, correct framing, and stable throughput for your application.
• Ongoing maintenance: enable firmware updates when available, review diagnostics logs periodically, and implement appropriate security measures to protect remote access. Document the configured mappings for future reference and scalability.
