Professional DVI KVM Extension

The Gefen EXT-DVIKVM-LAN-LRX extends DVI video, USB 2.0 peripherals, RS-232 control and stereo analog audio over a Gigabit LAN. A sender unit provides a local DVI output for on-site monitoring while the receiver connects up to four USB devices and includes a three-port Ethernet switch. Maximum supported resolutions are 1080p and 1920 x 1200 WUXGA at a 165 MHz pixel clock.

Verify Network And Cabling

Ensure your infrastructure uses CAT5/6 cabling with runs no longer than 328 ft between sender and receiver. The Gigabit switch must support 8k jumbo frames for multipoint matrix operation. Confirm the sender requires a 5V DC 2.6A locking supply and the receiver a 5V DC 4A locking supply. Video sources must output a DVI 29-pin digital-only signal.

Replaces Point-To-Point Extenders

This IP-based system replaces direct CAT5/6 KVM extenders when you need a virtual matrix of up to 65,000 endpoints or shared USB access across multiple receivers. The jump is worth it for installations requiring flexible routing between mixed HDMI, DVI and VGA sources without dedicated cabling per link. It is not suited for buyers needing uncompressed video beyond 1920 x 1200 or fibre-distance transmission.

Questions about this item

What cables and power supplies come with the EXT-DVIKVM-LAN-LRX, and which items must be sourced separately?

The unit includes an L-shaped mounting bracket and locking 5 V DC power supplies (2.6 A for the sender, 4 A for the receiver). CAT5/6 network cables, DVI cables, USB peripherals and a Gigabit switch with 8 k jumbo-frame support are not included.

When should I choose the LRX receiver instead of a standard transmitter/receiver pair?

Select the LRX when you need a local DVI monitor at the sender location plus four USB 2.0 ports, RS-232 and stereo audio at the receiver, and the ability to join a virtual matrix of up to 65,000 units over Gigabit Ethernet.

What does the 165 MHz pixel clock mean for the video I see at the receiver?

It supports input and output resolutions up to 1080p Full HD and 1920 x 1200 WUXGA over the IP link.
