The DVI KVM over IP extends DVI, USB, 2-way analog audio, RS-232, and IR, over a Gigabit Local Area Network. Resolutions up to 1080p Full HD and 1920 x 1200 (WUXGA) are supported. HDMI digital audio is also supported when using HDMI sources and displays with HDMI-to-DVI adapters. 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 including the Gefen KVM over LAN products with HDMI, DVI, or VGA video, to create a virtual crosspoint matrix of just over 65,000 Sender and Receiver units total, depending on the network bandwidth and number of ports on the network switch (see Note). Any combination of HDMI, DVI, and VGA Senders and Receivers can be used**. 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. USB 2.0 data rates up to 480 Mbps are supported in addition to backward-compatibility with USB 1.1. Each Receiver unit provides two USB ports with up to 500mA current draw per connector, providing access to keyboard, mouse, and other compatible devices. Bi-directional analog audio capability allows audio to be transported between the Sender and the Receiver units. The built-in mic pre-amp on the Receiver unit ensures compatibility with a variety of microphones. IR commands from the Receiver side can be extended to sources connected to any of the Senders units. RS-232 serial control can also be extended between each Sender and Receiver unit. The built-in Web server interface makes set-up and configuration simple and intuitive.
