Instant DB9 Serial Port from USB
Add an RS232 to USB adapter connection to any modern laptop or desktop instantly. This adapter supports PLCs, barcode scanners, GPS units, modems, and other legacy DB9 connectors without requiring external power. It is bus-powered from any USB port.
Genuine FTDI Chipset for Stable Performance
Built with an authentic FTDI chip, this adapter ensures reliable RS-232 data transmission over 1,000kbps. It eliminates driver failures and blue screen issues commonly reported with clone-based serial adapters on various Windows versions.
Dual-Color LED Indicators for Real-Time Diagnostics
Individual LED indicators monitor each RS-232 signal pin (TXD, RXD, DTR, DSR, RTS, CTS, DCD, and RI) in green or red. This feature allows you to confirm live data flow and troubleshoot serial connections without the need for additional software or test equipment.
Broad OS Support and Plug and Play Setup
This adapter works seamlessly with Windows 11, 10, 8, 7, Vista, XP, Linux, and macOS right out of the box. The FTDI USB to serial drivers are widely supported across major operating systems and retain COM port assignments across reboots—an essential advantage over Prolific-based alternatives.
Compact 16-Inch Cable for Rack and Server Installs
The convenient 16-inch length keeps cable runs tidy in server racks, industrial panels, and bench setups. Its compact USB connector and short cable design help reduce port congestion where space is limited around recessed or closely spaced USB 2.0 ports.
