USB to RS232 Terminated Audio Jack


  • Converts the terminated connection with a 3.5mm audio jack which provides access to the TX, RX and GND signals.
  • Works in the same way as DB9 connector, however, the audio jack serves as a preparatory connection through hardware specifically designed to use an audio jack for serial communication, the rings in the audio jack serve the signal instead of typical pins.
