AUSTIN, TEXAS — March 5, 2001 — Web Visio is a software development tool that helps OEMs
painlessly produce control, monitoring and HMI systems that run on the embedded, diskless
Windows CE 3.0 real-time operating system, as well as communicate via Internet, wireless,
Ethernet, and standard industrial networks. It lets OEMs avoid the agony and frustration usually
involved in dealing with Windows 3.0, because it handles most, if not all, of the detailed and
tedious procedures required in making such a system work.
