USB to RS232/RS422/RS485 Optical Isolated Converter

1.The TRP-C08 allows you to connect your serial devices to
  systems by using a USB interface. With data format auto
  detecting and baud rate auto switching functions, TRP-C08
  is automatically able to detect the data flow and switch
  the direction of the data lines as well as to
  automatically configure RS422/485 signals to any baud
  rate without external switch setting. Equipped with
  3000VDC of isolation and internal surge-protection on
  each data line, TRP-C08 gives the host computer and
  module itself entirely protection from destructive
  voltage spikes and dangers of unregulated voltages
  input. TRP-C08 also features a high-speed 115.2 Kb/s
  transmission rate, and supports various O.S.
