FTDI based USB to TTL Serial Cable are designed using the standard FT232RL chipset. The cables provide a fast, simple way to connect devices with a TTL level serial interface to USB. The cables are available with a 6-way SIL, 0.1 inch connector. TTL levels are 3.3V. The TTL-232R cables are a family of USB to TTL serial UART converter cables incorporating FTDI's FT232RQ USB to Serial UART interface IC device which handles all the USB signaling and protocols. The cables provide a fast, simple way to connect devices with a TTL level serial interface to USB. Each TTL-232R cable contains a small internal electronic circuit board, utilizing the FT232R, which is encapsulated into the USB connector end of the cable. The other end of the cable comes with a selection of different connectors supporting various applications. Cables are available with either a 6-way SIL, 0.1 inch pitch connector, a 3.5mm Audio Jack, an 8 way, keyed 2 mm pitch connector (intended for use with VMUSIC2 or VDRIVE2) or bare, tinned wire ended connections. The USB side of the cable is USB powered and USB 2.0 full speed compatible. Each cable is 1.0m long and supports a data transfer rate up to 3 Mbaud. Red wire: 5V. Black wire: GND. White wire: RXD.
