1 Description

The USB 2.0 Hi -Speed to UART cable incorporates FTDI’s FT232H USB to UART interface IC dev ice which handles all the USB si gnalling and protocols. The cable provides a fast, simple way to connect devices with 3.3 volt digital interfaces to USB. The C232HD UART cable contains a small internal electronic circuit board , utilising the FT232H, which is encapsulated into the USB connector end of the cable. The FT232H is a single channel USB 2.0 Hi -Speed (480Mb/s) to UART IC. For full details, features and enhancement descriptions please refer to the FT232H datasheet. The digital interface of the cable is made up of ten individual wires which are terminated with single pole connectors which can be connected next to each other on a male header. The cables digital interface logic is 3.3 volts. The USB side of the cable is USB powered and is USB 2.0 Hi-Speed compatible. The cable is 1.8m long and supports a data transfer rate up to 12 Mbaud. The C232HD UART cable requires USB drivers, available free from http://www.ftdichip.com , which are used to make the FT232 H in the cable appear as a virtual COM port (VCP). This then allows the user to communicate with the USB interface via a standard PC serial emulation port (for example TTY). Another FTDI USB driver, the D2XX , is used with application software to directly access the FT 232H on the cable though a DLL. This is illustrated in the Figure 1-1.
