The DVX500 consists of a Transmitter unit and a Receiver unit. These two devices enable long-distance, loss less transmission of DVI video signals between a digital video source and a digital display device. The DVX500 is equipped with DVI-digital (Digital Visual Interface) connectors for a single-link and optional keyboard and mouse. The DVX500 receiver is small enough to be attached near a projector. With the DVX500, the maximum distance between the source and digital display is 330 feet (100 m) using cat5 and up to 10,000ft using fiber optic VGA, DVI and more DVX500 supports traditional analog VGA as well as digital DVI. All combinations of DVI and VGA (graphics cards and monitors) are supported allowing equipment to be mixed. You could use DVX500 today to extend (with perfect image quality) your existing SVGA equipment. Later, if you purchase a DVI monitor you can use it with DVX500 even though your computer is equipped with a VGA graphic card. When you finally upgrade to a DVI graphic card, DVX500 will continue to extend your system without any reconfiguration.
