The FTDI Chip serial to USB connector module can be used to upgrade an RS232 port to an active USB port without the need to redesign the PCB. This active connector contains all the USB to UART (vice-versa) conversion electronics and is designed to fit directly into the same PCB footprint as a PC compatible UART DB9 connector. This high-speed USB to 1-Port RS232 level UART module that can replace an RS232 level UART DB9 female connector.

Easy placement for an standard female RS232 DB9 footprint of a device
A selection of RS232, 3.3V, or 5V UART signal levels
Works with USB 1.1 and 2.0 host and hub ports
Industry standard FTDI chip set and device drivers for maximum compatibility
Microsoft Windows WHQL-certified, Mac OS X, Linux and Windows CE device drivers
Installs as a standard Windows COM port
128b transmit buffer and 256b receive buffer
UART data signals TxD, RxD, RTS, CTS, DSR, DTR, DCD, RI, GND
