Bring legacy serial equipment into the network without adding a separate power supply. This PoE serial to Ethernet adapter connects RS-232 devices to an IP-based environment through a single DB9 serial port and one RJ45 10/100 Mbps Ethernet port. With 802.3af PoE support, it simplifies deployment at the edge, where power outlets are limited and uptime matters. Designed for remote device access, it supports Telnet, TCP server, TCP client, and UDP modes, giving infrastructure teams flexible ways to integrate serial endpoints into existing workflows. Windows-based virtual COM and device management software helps map serial devices into familiar administration tools, while the web UI provides direct browser-based control. The metal housing, wall or DIN rail mounting options, and ESD level 4 protection make it suitable for industrial and commercial environments. For teams maintaining POS systems, remote sensors, CNC controllers, or scales, this adapter provides a practical path to centralized management without replacing working equipment.
