MODEL- IC485AI             VENDOR- ATEN TECHNOLOGY                        
                                                                            
FEATURES- RS-232 to RS-422/RS485 Bi-directional Isolated Converter
       IC485AI, the Isolated Converter, is a bi-directional converter that 
        transparently converts RS-232 signals to RS-422/RS-485 signals (and 
        vice versa), thus permitting the creation of reliable long distance 
        communication systems using standard computer hardware. 
       IC485AI provides point-to-point, multi-drop, and simplex operations 
        over 4000 feet. Designed with built-in optocouplers for exceptional 
        signal isolation, plus transformers for excellent power isolation, 
        this extremely reliable isolated converter enhances the quality of 
        the data communication. At the same time, it protects your 
        equipment from electrical surges of up to 2000 Volts. 
  Includes IC485AI bi-directional isolated converter, Power adapter,
     User manual and Warranty registration card.
