Gefen EXT-DVIKVM-LANS プリント

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. The DVI KVM over IP is perfect for large scale remote workstation access and digital signage applications.  

 

If you are connecting multiple Sender units, use the built-in Web interface to assign a unique channel and/or switch between 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.  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 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”, 

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 www.gefen.com).  

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.
