Product Description:

Description:

FTDI cables are the family of USB to TTL serial UART converter cables and they are incorporated with FT232R IC.The chip handles all the protocol of converting USB data to UART serial data. The cables provide a fast, simple way to connect devices with a TTL level serial interface to USB and they do not require any additional software installation and setting before using them. So they are simple plug and play devices.

Pin Configuration

As shown in FTDI cable pin diagram, one end of FTDI cable is connected to USB and other end we have six output pins. These six pins are RS232 output. The function of each pin is stated in below table.
