DriverGenius SerialGuardX | FTDI USB-C to RS232 DB9 Serial Adapter with 9 LED Status Indicators (1-Pack)
GThe DriverGenius SerialGuardX Series RS232-ESD9C FTDI USB-C to RS232 Serial Adapter is designed for industrial automation, PLC programming, equipment configuration, embedded development, and other applications that require dependable serial communication. Powered by the proven FT232RL chipset, it provides stable USB-C to RS232 connectivity for both modern computers and legacy serial devices. Compatible with Windows, macOS, and Linux, it supports reliable communication across a wide range of industrial and commercial environments.
Equipped with real-time serial signal monitoring, the RS232-ESD9C features 9 status LEDs (TXD, RXD, RTS, CTS, DSR, DTR, RI, CD) that provide immediate visual feedback on communication activity. These indicators help technicians, engineers, and system integrators quickly verify data transmission, identify signal activity, and diagnose communication issues during installation, maintenance, and troubleshooting.
With integrated ESD protection rated at 8kV–15kV according to IEC 61000-4-2 standards, the adapter helps protect connected equipment from electrostatic discharge and accidental contact-related interference. This additional protection is particularly valuable in industrial environments where sensitive serial equipment operates continuously.
The USB-powered design requires no external power adapter and supports plug-and-play installation. Whether connecting PLCs, industrial controllers, serial instrumentation, CNC equipment, point-of-sale systems, embedded devices, or legacy hardware, the SerialGuardX Series provides dependable USB-C to RS232 communication for demanding applications.
