With data transfer rates up to 12Mbps, the Universal Serial Bus (USB) port is the fastest, easiest route for shuttling information between your PDA and a PC or Macintosh computer. The USB PDA Adapter gives Palm and other popular PDAs the USB Plug-and-Play advantage. ??The DB9 Serial Port of the built-in device cable connects to the PDA and the USB connector connects to the computer, and status LEDs allow monitoring of data transfer activity. Besides, it works not only with Palm organizers but with other hand-held PDAs as well, and includes installation software for Windows 98 or 2000, or Mac OS 8.6 or higher.
