novalink Hardware KonverterSerial-to-LAN

Legacy serial equipment often can't communicate over modern networks, leaving critical devices isolated and unmanageable. The NOVALINK HW-SER-LAN/KS-NLSO43 Serial-to-LAN Converter bridges that gap, enabling RS-232, RS-422, or RS-485 devices to connect directly to an Ethernet network. This compact, industrial-grade unit makes it possible to monitor and control serial-based machinery, POS systems, security devices, and more from anywhere on your LAN or over the internet.

Who is it for

System integrators, industrial automation engineers, and IT administrators who need to bring legacy serial devices into IP-based infrastructures. It is ideal for factory floors, building automation, retail environments, and remote monitoring applications where reliability and simple configuration are essential.

Main features

• Supports RS-232, RS-422, and RS-485 interfaces via software selection, with a DB9 male connector for RS-232 and a 5-pin terminal block for RS-422/485.
• One 10/100BASE-TX Ethernet port with RJ45 connector for network connectivity.
• Flexible operating modes: Virtual COM Port, TCP Server, TCP Client, UDP, and Pair Connection.
• Wide serial baud rate range from 300 bps to 230.4 Kbps, with configurable data bits, parity, stop bits, and flow control.
• Supports TCP/IP, UDP, ICMP, ARP, DHCP, HTTP, and DNS protocols for seamless network integration.
• Web-based configuration and Windows utility for easy setup and management.
• DIN-rail and wall-mount options for flexible installation in industrial environments.
• Robust metal housing with LED indicators for power, link/activity, and serial Tx/Rx.
• Wide power input range of 9-30V DC via a 2-pin terminal block.

Tips

For best performance, use shielded Ethernet cable and ensure proper grounding in industrial environments. When connecting RS-422/485 multi-drop networks, terminate the bus correctly to avoid signal reflections. The web interface allows remote configuration, but initial setup may require a direct connection to a PC using the Windows utility.
