The FTDI chip USB to RS485 adapter board incorporates FTDI’s FT4232H Hi-Speed USB2.0 (480Mb/s) to quad serial UART interface IC device. It handles all the USB signalling and protocols. The adaptor provides a fast and simple way to connect devices with an RS485 interface to USB. The integrated electronics circuit utilise the FT2232H and include RS485 level shifters plus TXD/RXD LEDs to provide a visual indication of data traffic through the module. This module uses a standard USB mini-B device connector for connection to an upstream host or hub port. This board supports Windows Server 2008, 2003, Vista, XP, 2000, Windows CE, Linux, and Mac OS X.
