FEATURES- USB Twin Serial Adapter
       There is good reason why we sell more Mac USB serial adapters than 
        any other company. We've been making PCI serial cards and USB 
        serial adapters for Mac OS for more than 10 years!
       Our USB Twin Serial Adapter is recommended by dozens of serial 
        device manufacturers and has been certified by Apple for use with 
        Final Cut Pro.
    Includes Adapter with built in USB cable, CD with driver software and 
      user guide.
* Plugs into a USB port on your Mac 
* Provides two RS-422 ports for connection to serial devices 
* Draws power from the USB connection -- a power adapter in not required 
* Has been qualified by Apple, Avid and others for connection to video 
  decks.
* Supports use of multiple adapters on one Mac 
* Compatibility
   For use with RS-232 and RS-422 serial devices including modems, graphics 
   tablets, video decks, serial PDAs, serial printers, GPS devices, and 
   medical/scientific instrumentation. Does not support AppleTalk/Local 
   Talk. Some serial devices, including many serial printers, do not have 
   drivers for Mac OS X and therefore will not operate under Mac OS X. 
   Check with the serial device manufacturer to confirm that Mac OS X is 
   supported. (For Epson Stylus Printers, use our USB Parallel Printer 
   Adapter if running Mac OS X.)
