Create a Virtual, Cross-Point Matrix on any Network with Gefen’s New DVI KVM over IP with Local Output

Gefen’s new DVI KVM over IP with local output helps improve computer systems by increasing workstation access from anywhere on the LAN and streamlining equipment.

This sender/receiver system, when combined with aGigabit Ethernet switch, enables computer data access using a keyboard,video monitor and mouse (KVM). The sender unit delivers high resolution video in the DVI format with four USB peripherals, analog stereo audio and RS-232 control signals through the switch to the receiver unit, which connects to the KVM workstation. Each sender and receiver unit can be connected to the LAN by one CAT-5 cable in distances up to 100 meters for added convenience. The DVI KVM over IP can be implemented with multiple sender and receiver units on the same LAN.

When each sender and receiver is configured to a unique IP address, up to 256sender and 256 receiver units can be routed through the same LAN,creating a scalable, virtual cross-point matrix with no additional wiring. Sender and receiver units are also interchangeable with Gefen’s HDMI andVGA KVM over IP models. DVI, KVM and HDMI workstations can all be configured into the same virtual matrix system. Video resolutions are supported up to 1920x1200 at 60 frames per second regardless of the video format.

The DVI KVM over IP uses a method of visually loss less compression, and boasts latency of less than two frames. A web server interface is included for easy configuration and setup. Each receiver comes equipped with an integrated 3-port Ethernet switch for connecting additional computers at the remote location. One DVI output on the sender unit is provided for local video monitoring.

How It Works

  • If you are connecting multiple Sender units, use the built-in Web interface to assign a unique channel IDs to the Sender units.
  • Use the included DVI cable to connect a computer or other DVI source to the Sender's DVI input.
  • Use the included USB and RS-232 cables to connect the computer's USB and RS-232 interfaces to the Sender unit.
  • Connect audio Line In and audio Line Out as needed to the Sender.
  • If your computer or other source is IR controllable, connect a Gefen IR emitter to the Sender and attach it to the IR sensor lens of the source.
  • Connect the DVI output of the Receiver to your Hi-Def display.
  • Connect your USB devices, RS-232 devices, microphone, and headphones or amplified speakers to the Receiver unit.
  • If the Receiver is not installed in the line-of-sight of the end-user, and IR commands will need to be sent to the source, connect a Gefen IR extender (EXT-RMT-EXTIRC or EXT-RMT-EXTIRN) to the Receiver.
  • Connect the Sender and Receiver units to each other directly or through a Gigabit Ethernet switch, using CAT-5e or better cables. Each cable run can be up to 330 feet (100 meters) in length. If the Sender is connected to your LAN, you can use the two additional RJ-45 ports on the Receiver to connect computers and other IP enabled devices.
  • Connect the included 5V power supplies to the Sender and Receiver units and to available electrical outlets.
  • Power-on all associated equipment.
  • Use the Mode button on the Sender to optimize the picture for sharper still images or smoother video motion.
  • When using multiple Senders and Receivers as a "Virtual Matrix", use the Switch button on the Receiver or the web interface to switch between Senders.
  • When using multiple Senders and Receivers as a "Virtual Matrix", you can connect to any of the Senders within the network by accessing the web interface of each Receiver unit via a web browser on a mobile device or computer, or by using the Gefen Keyboard Switching Controller software (available for download at

Note: A Gigabit switch is required. The Gigabit switch must support 8k jumbo frame packets in order for multicast mode to operate. If your LAN is not dedicated to Gefen KVM-LAN products exclusively, then a managed switch is highly recommended.
