      The cable that you are using is not listed in the datasheet for the controller.

      I believe that you have the wrong cable.
      The above link will give you the RS232 pinout. 
      I have had success communicating using the USB port of a computer using the Ugreen USB to RS232 cable.

      Hope this helps you out.
