Using KVM extenders, computers can be separated from their associated input and output devices by up to 10 kilometers. Signal transmission over Cat X and fibre connections is achieved with no inherent delay or loss of quality - even at the highest video resolutions.

The new Draco vario dual-head enables the connection of two DVI monitors (at maximum 1920 x 1200 pixels for each monitor). To extend signals only one single Cat X or fiber cable link is needed, saving the expense of a second extender and reducing cabling costs and installation effort. When used in conjunction with KVM matrix systems, the Draco vario dual-head extender is designed to save valuable matrix ports.

Its sister product, Draco vario dual link, enables the transmission of DVI signals to one single monitor up to a resolution of 2560 x 2048 pixels. Extension of signals requires a single data cable. Both extenders offer additional USB ports for connection of keyboard, mouse or graphics tablet.

The extenders are compatible with regular single-head/single extenders: consoles can access single-head/single link CPU units instantaneously. This is crucial for use with monitors that are limited to a small set of dual link inputs, for example Apple Cinema monitors. In this situation, signals from single-head/single link sources are embedded within the dual link signal format and can be switched with no discernible switching delay. Single-head/single link images are displayed at their own native resolution within a blanked area on-screen.
 
Both products can be installed in all types of Draco vario chassis and are compatible with all upgrade modules of the Draco extender family.
