Ftdi Usb Serial Adapter

The Sabrent CB-FTDI USB to Serial converter is the perfect solution for transferring data from a PDA or digital camera. The USB to DB9 provides a connection between an available USB port and the more traditional RS-232 serial port found on many devices.

Other things to consider would be compatibility with Windows 10. The manufacturer (FTDI) of the processor chips for our USB to Serial adapter 'Ultimate', 'PRO' and 'Thunderlinx' versions have validated that the drivers are fully compatible with the Consumer Preview, Developer Preview versions and officially released consumer versions of Windows 10.

This is great news since you now won't have to spend money on a new USB to serial adapter once you decide to upgrade to Windows 10.

Things to avoid:

  • Avoid adapters with a low-cost processor chip such as Prolific or WCH (WinChipHead). The drivers are poorly written, incompatible with newer operating systems and creates unreliable communication.
  • Avoid adapters with a low output power (less than 5VDC). Low output power makes the communication unreliable or even impossible.

The Architecture of a USB to serial adapter

The design and selection of components of a USB to serial adapter is what determines failure or successful data transfer. Most USB to serial converters has built-in ADDC (Automatic Data Direction Control) so they automatically can control the data flow direction, which makes handshaking obsolete, however this only applies to the RS485 protocol, not RS232.

Below is a simplified schematic of a typical well designed circuitry.


At a block level a USB to serial adapter consists of a USB serial processor chip, a serial driver chip and if the adapter is isolated there will be optocouplers in front of the USB and / or serial ports. The above design consists of a FT2232 USB serial processor from FTDI, which is a dual serial port processor. This processor is combined with a SP213 high-speed RS232 transciever from Exar which makes the overall performance of the adapter solid and reliable.
