FTDI DB9 to USB Male Converter Module RS232

The FTDI DB9 to USB Male Converter Module provides a seamless solution for upgrading legacy RS232 connections to modern USB interfaces. Designed to directly replace an existing DB9 connector, this module offers a drop-in USB replacement for standard male or female RS232 connections. It replaces the DB9 RS232 connector pin-for-pin with a USB mini-B connector, meaning the application PCB requires no modification—simply swap the D-type connector with the appropriate DB9-USB-RS232 module.

Containing all the necessary electronics to convert between USB and RS232 signal levels, this module adds a USB serial port by connecting directly to the RS232 DB9 footprint of your device. It utilises the industry-standard FTDI chipset, ensuring maximum compatibility across various operating systems, including Microsoft Windows WHQL-certified drivers, Mac OS X, Linux, and Windows CE. The module installs as a standard Windows COM port and supports Windows Server 2008, 2003, Vista, XP, and 2000.
