   FTDI US232R : USB to RS-232 cable. A USB-to-serial adapter or simply USB adapter is a type of protocol converter that is used for converting USB data signals to and from serial communications standards (serial ports). Most commonly the USB data signals are converted to either RS-232, RS-485, RS-422, or TTL-level UART serial data.

   While chip manufacturers such as Prolific Technology, FTDI, Microchip, and Atmel manufacture USB chips and provide drivers that expose the chip as a virtual RS-232 device, the chips do not use USB CDC protocol and rather use their custom protocols, though there are some exceptions (PL2305 [2]).

5. RS-232 - Wikipedia

   en.wikipedia.org/wiki/RS-232

   The standard specifies a maximum open-circuit voltage of 25 volts: signal levels of ±5 V, ±10 V, ±12 V, and ±15 V are all commonly seen depending on the voltages available to the line driver circuit. Many RS-232 driver chips have inbuilt charge pump circuitry to produce the required voltages from a 3 or 5 volt supply. RS-232 drivers and ...
