Device server Lantronix EDS3000PS 8 Ports 1GbE RS-232

Lantronix EDS3000PS 8 Ports 1GbE RS-232 is an industrial device server that provides Ethernet-to-serial conversion for up to eight RS-232 devices over a single 1GbE network connection. The unit is designed to integrate legacy serial equipment into modern IP networks, enabling remote management, centralized data collection and secure serial-over-IP communications in industrial environments. It supports continuous operation and is intended for installations where reliable, low-latency serial connectivity and networked access are required.

Advantages

The device server offers eight independent RS-232 ports with individual serial session handling and a full 1 Gigabit Ethernet interface for high-performance network throughput. It supports standard TCP/IP protocols and common serial-to-IP modes, allowing transparent serial tunneling and socket-based connections. The compact rack- or DIN-mountable form factor and industrial-grade design provide stable operation in control cabinets and network closets. Built-in management features simplify configuration and monitoring without requiring changes to existing serial equipment.

Suitable for

• Integrating PLCs, meters and sensors into Ethernet-based SCADA and automation systems
• Connecting POS terminals and receipt printers to centralized servers
• Telemetry, remote data acquisition and environmental monitoring
• Industrial control, building management and access control systems

Key specifications

• Serial interfaces: 8 × RS-232 ports for asynchronous serial communication
• Network interface: 1 × 10/100/1000 Mbps Ethernet (RJ-45)
• Serial data rates: standard baud rates supported up to typical RS-232 speeds
• Operating modes: TCP server, TCP client, UDP, RFC2217/COM port redirector and raw socket modes
• Mounting: DIN-rail or rack compatible compact enclosure
• Power: industrial DC power input with support for continuous operation

How to use

Install the Lantronix EDS3000PS in a networked control cabinet or equipment room and connect serial devices to the RS-232 ports using standard DB9 or terminal connections as required. Connect the Ethernet port to your LAN or VLAN switch and apply the appropriate DC power. Configure network settings and serial port parameters through the device’s web-based management interface or supplied management utility. Map each serial port to a network socket or virtual COM interface on host systems to enable transparent serial communications over IP. Apply access controls and logging according to your IT policies before placing the device into production.

Usage recommendations

Use shielded cables for serial and Ethernet runs in electrically noisy environments, and place the device on a stable power supply with surge protection. Assign fixed IP addresses or reserve DHCP addresses in critical installations, and test each serial link for correct baud rate, parity and flow control settings. Regularly check firmware updates from the vendor and perform scheduled backups of configuration settings to ensure reliable long-term operation.
