The EL4500 KVM Extender provides DVI compressed video, audio and and full USB 2.0 (480Mbps) up to 100 meters over Cat 5e (or better) cable. The EL4500’s video and USB extension can be used over a Local Area Network (LAN), simply by plugging the local extender into one LAN port and the remote extender into another LAN port, the two ends instantly find each other with Rapid Pairing Protocol™. This gives the option to save on installing additional cabling.

Applications include keyboards, mice, low speed game controllers, microphones, 1.1 web cameras, flash drives, hard drives, 2.0 web cameras, 2.0 digital cameras, and high speed game controllers with vibration/sound. Video resolution is 1680 x 1050 and does not degrade when extended the full 100 meter distance.


  • HD Video: DVI Compressed, 1680 x 1050 resolution, 24-bit color depth. Resolution does not degrade with distance.
  • Direct Connect: Directly connect the local extender to the remote extender using a single Cat 5e (or better) cable up to 330 ft (100m). This mode of operation is ideal for installations requiring USB 2.0 up to 480Mbps.
  • Rapid Pairing Allows for connection on a LAN or through a network switch. The system can be utilized on virtually any Ethernet network since it operates at Layer 2 and uses MAC addresses. There is no additional overhead or setup since it doesn’t use the TCP/IP layer and typical network usage can be as low as 50Mbps.
  • Audio: Integrated two channel audio with microphone and headphone I/O.
    OS Support: Compatible with all major operating systems. No drivers required.
  • Installation Ease: True plug and play (no set up required). Utilizes a single Cat 5e (or better) cable for desktop extension simplifying installation.
