The DTECH USB to RS422 / RS485 Serial Port Converter (1.5 Feet) is an industrial-grade adapter designed for reliable data communication between a computer and serial devices. Built with the high-performance FTDI FT232 chipset, it is widely regarded as one of the most stable solutions for avoiding common issues like computer freezes or COM port conflicts.
Dual Mode Support: Supports RS485 (Half Duplex) and RS422 (Full Duplex) communication.
Industrial Protection: Provides 600W surge protection and 15KV ESD protection to safeguard sensitive equipment from electrical damage.
Smart Indicators: Features built-in LED Troubleshooting Indicators (Power, TX, and RX) to visually confirm data transmission.
Plug & Play: No external power supply or jumper settings required; it uses I/O auto-conversion circuitry to automatically control data flow direction.
This cable is compatible with nearly all major operating systems:
Windows: 11, 10, 8.1, 8, 7, XP, and Vista.
Other OS: Mac OS, Linux, and WinCE.
Peer Tip: While the cable often works via Plug-and-Play, for the best performance on Windows 11 or Mac, it is recommended to download the latest VCP (Virtual COM Port) drivers directly from the FTDI Chip website to ensure the most stable connection.
