Designed to be versatile and
adaptable, the Vision Switch provides a complete 16x16 video crosspoint switch
within a single PCI plug-in card. Larger switch sizes are also possible by
adding a second Vision Switch card to produce either a 32x16 or 16 x 32 switch.
Vision Switch is supplied with driver software for Windows®
NT/2000. A simple and intuitive Windows application program is provided
enabling users to control the crosspoint switch or, for users who wish to
control Vision Switch from their own software, a Software Development Kit (SDK)
is also provided.
Vision Switch may also be used with our Horizon4VW
range of multi-screen graphics adapters. In this configuration
Vision Switch is connected to the Horizon via inter-card ribbon cables,
enabling the Horizon video overlay’s to select 1 of 16 possible video
sources. A single Vision Switch card will support up to four Horizon4VW
graphics adapters
