RS232 to RS422 Serial Converter Adapter, FDX FullDuplex RS232RS422 Bidirectional Signal Switch, No External Power Required Passive Serial Adapter for Industrial Serial Communication Equipment Conne

This passive RS232 to RS422 fullduplex serial converter realizes bidirectional signal conversion between RS232 and RS422 interfaces without external power adapters. It extracts tiny working power from existing serial signal lines, eliminating extra power wiring trouble. Adopting FDX fullduplex transmission mode, it supports simultaneous sending and receiving data, maintaining complete serial communication flow. Compared with native RS232, RS422 delivers longer transmission distance and stronger antielectromagneticinterference performance, suitable for industrial control, PLC, serial instrument, accesscontrol equipment and serial debugging projects. Small compact body allows direct plugin installation, no driver installation or complex parameter setup required. It solves compatibility problems when connecting RS232standard devices to RS422 peripherals and vice versa. Please note this is a passive converter, stable performance depends on adequate signal voltage from connected serial ports. Serial cables are not included in package. Do not connect incompatible highvoltage signals to avoid burning internal circuit components.
