StarTech.com 2-Port Serial to Ethernet Adapter

The StarTech.com 2-Port Serial to Ethernet Adapter is a compact, high‑performance device that bridges legacy RS232 serial equipment with modern Ethernet networks. Designed for industrial automation, network management, and remote monitoring, this adapter delivers reliable connectivity in both wall‑mounted and DIN rail configurations.

Key Design Features

• Dual Serial Ports (DB9): Two independent RS232 interfaces allow simultaneous connection to serial devices such as PLCs, routers, or legacy servers.
• RJ45 Ethernet Interface: Standard 100 Mbps RJ45 port supports IEEE 802.3i and IEEE 802.3u specifications for broad network compatibility.
• Metal Housing: Robust aluminum enclosure protects against electromagnetic interference (EMI) and mechanical stress, ensuring long‑term reliability in harsh environments.
• Wall/DIN Rail Mounting: Flexible mounting options enable installation on walls or within DIN rail panels, ideal for control cabinets or rack‑mounted systems.
• Compact Footprint (179 mm): Small size facilitates integration into tight spaces without compromising performance.

Electrical and Environmental Specifications

• Operating Temperature: -20 °C to +75 °C, suitable for industrial settings.
• Humidity Range: 5 % to 95 % RH (non‑condensing), ensuring stable operation in varied climates.
• Serial Port Voltage Levels: Standard RS232 ±12 V signals with automatic voltage detection and protection.
• Power Supply: 5 V DC input via the RJ45 port, eliminating the need for separate power adapters.

Software and Protocol Support

• TCP/IP & UDP/IP: Full support for both transport protocols enables flexible data transmission strategies.
• Telnet, SSH, and Web Interface: Remote configuration and monitoring through secure shell or web browser.
• SNMP (v1/v2c): Network management integration for automated status reporting.
• Virtual Terminal (VT100/ANSI): Built‑in terminal emulation allows direct interaction with connected serial devices.

Use Cases and Applications

• Industrial Automation: Connect PLCs, SCADA systems, or motor controllers to a central network for real‑time data acquisition.
• Remote Device Management: Access legacy serial equipment from anywhere on the LAN without physical proximity.
• Network Infrastructure: Bridge older serial console ports of switches and routers to modern management networks.
• Data Logging: Stream serial sensor data over Ethernet for centralized storage and analysis.

Installation Guide

1. Mounting: Secure the adapter to a wall or DIN rail using the provided screws. Ensure proper ventilation around the metal housing.
2. Serial Connections: Attach DB9 cables from the device’s serial ports to the target RS232 equipment. Verify correct pinout alignment.
3. Ethanet Connection: Connect an RJ45 cable from the adapter to the LAN switch or router.
4. Power On: The adapter receives power through the Ethernet connection; no additional power supply is required.
5. Configuration: Access the web interface via a browser, set IP address (static or DHCP), and configure serial port parameters such as baud rate, parity, stop bits, and flow control.

Security Features

• SSH Encryption: Secure shell access protects configuration changes from eavesdropping.
• Access Control Lists (ACLs): Restrict IP addresses that can communicate with the adapter.
• Firmware Updates: Over‑the‑air updates ensure the device remains protected against emerging vulnerabilities.

Compliance and Certifications

• TAA Certified: Meets U.S. Department of Defense standards for electronic equipment.
• CE Marked: Compliant with European safety, health, and environmental protection requirements.
• RoHS Conformant: Free from hazardous substances such as lead, mercury, and cadmium.
