The UGREEN 80110 (model CM261) RS232 to RS485 converter is a commercial-grade signal interface adapter designed for industrial and automation applications. It enables seamless bidirectional communication between RS232 (EIA/TIA RS-232C) devices (such as PCs, legacy equipment) and RS485 networks (multi-drop bus environments) — allowing you to connect one RS232 port to up to 32 devices on an RS485 bus. With half-duplex two-wire operation, automatic RX/TX direction control, long-distance transmission up to approximately 1.2 km (4000 ft) on RS485, and built-in surge protection (600 W per line on RS485), this converter is ideally suited for reliable, long-haul, industrial-grade data communication.
