Video over IP solution for extending DVI, USB, RS-232, and audio. The DVI KVM over IP extends DVI, USB, analog audio, and RS-232, over a Gigabit Local Area Network. Resolutions up to 1920 x 1200 (WUXGA) and 1080p Full HD are supported. HDMI digital audio is also supported when using HDMI sources and displays with HDMI to DVI adapters. Local monitoring of video is made possible by the DVI Local Output connector on the Sender unit. The Sender and Receiver units can be automatically or manually configured to unique IP addresses to allow the connection of multiple Senders and Receivers to the same network. Multiple Receiver units can simultaneously connect to any Sender unit within the network to create a virtual crosspoint matrix of 256 Senders and up to a theoretical limit of just over 65,000 units total, depending on the network bandwidth and number of ports on the network switch. Each Receiver unit has a built in Ethernet switch and two additional RJ-45 Ethernet ports to allow for the connection of computers and other IP-enabled devices. Each Receiver unit allows the connection of four USB devices with up to 500mA current draw per port, providing access to keyboard, mouse, and other compatible devices. USB 2.0 data rates up to 480 Mbps are supported in addition to backward-compatibility with USB 1.1. Two Channel analog audio can be extended from each Sender to the Receiver units for use with headphones or powered speakers. RS-232 serial control can also be extended between each Sender and the Receivers. Built in web server interface makes set up and configuration simple and intuitive. Any combination of Gefen Video over IP HDMI, DVI, and VGA Senders and Receivers can be used together to create a "Virtual Matrix", where each Sender can be accessed by multiple Receivers. The DVI KVM over IP is perfect for large scale remote workstation access and for
