caption_attribution_description: English: The FTDI cable is a USB to Serial (TTL level) converter. The USB A connector houses a FTDI FT232RQ USB to serial interface IC. The other end of the cable is terminated with a 6 way 0.1” pitch header socket which provides access to the CTS#, TXD, RXD and RTS# signals, as well as GND and Vcc (5V).

context_page_description: A USB adapter is a type of protocol converter that is used for converting USB data signals to and from other communications standards. Commonly, USB adapters are used to convert USB data to standard serial port data and vice versa. Most commonly the USB data signals are converted to either RS232, RS485, RS422, or TTL-level UART serial data. The older serial RS423 protocol is rarely used any more, so USB to RS423 adapters are less common.
