DTECH USB to TTL serial UART converter cable provides a fast, simple way to connect devices with a 3.3V TTL level serial interface to USB port. It integrates FTDI FT232RL USB to serial UART interface IC device.
The FT232RL chip used is housed within the USB A connector. The cable is terminated with a 3 pin 0.1 inch pitch header socket which provides access to the transmit (Tx), receive (Rx) and GND connections.
The converter required USB drivers, available from http://www.ftdichip.com, which are used to make the FT232R on the PCB appear as virtual COM port(VCP driver). It allows users to communicate with the USB interface via a standard PC serial emulation port. Another driver it support is D2XX driver, can also be used with application software to directly access the FT232R on the PCB though a DLL application programming interface.
