USB to RS232 Adapter cable
The USB-RS232 adaptor cables are a family of communication devices from FTDI Ltd. This model,
US232R, provides a simple method of adapting legacy serial devices with RS232 interfaces to modern
USB ports by incorporating the FTDI FT232R bridge chip.
The US232R cable is available in two lengths 10cm (US232R-10) and 100cm (US232R-
100). Indicator LEDs provide status of Transmit (TX) and Receive (Rx)

DE-9P connector. The maximum RS232-level data rate is 1MBaud. The US232R adapter cable requires USB device drivers, available free from FTDI, which are used to make the US232R appear as a Virtual COM Port (VCP). This allows existing serial communications software, such as HyperTerminal, to exchange data through the US232R to a legacy RS232 peripheral device. -

FT232R datasheet, which is available from the FTDI website. 2.1.1 Integrated EEPROM Previous generations of FTDI’s USB UART devices required an external EEPROM if the device were to use USB Vendor ID (VID), Product ID (PID), serial number and product description strings other than the default values in the device itself. -
Page 11: Ftdichip-Id
This gives achievable baud rates in the range 183.1 baud to 3,000,000 baud. When a non- standard baud rate is required simply pass the required baud rate value to the driver as normal, and the FTDI driver will calculate the required divisor, and set the baud rate. See FTDI application note AN232B-05 for more details The US232R cable is limited to a maximum of 1 Mbaud because of the line driver within the circuit. -
