These USB to RS-232 / RS-422 / RS-485 converters provide a fast and simple method to convert serial UART to USB. The USB connector contains a small circuit board featuring the FTDI FT232RQ (RS 730-0168) serial UART interface IC to handle all the USB signalling and protocols. There are two LEDs to indicate data being received and transmitted.

The RS-232 has a maximum UART Baud Rate of 1 Mbaud while the RS-422 and RS-485 both have a maximum of 3 Mbaud.

These converters are supported with Microsoft WHQL certified VCP drivers for Windows, Apple Mac, and Linux. All of which are available, royalty-free from FTDI website. http://www.ftdichip.com
