The Universal Serial Bus (USB) is the most widely deployed PC peripheral interface in history, enabling simple plug and play connectivity for a wide variety of devices to enhance the computing experience. Developed to improve ease of use and provide flexible port expansion, USB has become an indispensable computing technology.
What is USB 1.1?
USB 1.1 provides support for two interface speeds: Low-Speed at 1.5 Mbps and Full-Speed at 12 Mbps. The two interface speeds target specific classes of devices to provide the most efficient and cost-effective interconnect solution. Low-Speed devices are typically interactive input devices such as keyboards, mice or game controllers. Full-Speed devices are typically application specific input devices such as microphones, cameras and printers.
What is USB 2.0?
USB 2.0 was developed to offer a complementary High-Speed transfer rate at 480 Mbps. Backwards compatible with the full speed and low speed transfer rates of USB 1.1; USB 2.0 delivers a significant bandwidth increase. USB 2.0 will continue to provide cost effective and convenient peripheral connectivity. Typical High-Speed devices are External Hard Drives, Flash Drives, Web Cameras and Scanners.
What is USB 3.0?
USB 3.0 Super-Speed systems will provide a performance enhancement of speeds up to 5 Gbps with distances up to 3 meters for newer storage and multimedia devices, greatly improving transfer times for large files and blocks of data. USB 3.0 devices and controllers are designed to be backwards compatible with USB 2.0 devices and controllers. For example, you can plug in a USB 3.0 device into a USB 2.0 controller port, or you could plug in a USB 2.0 device into a USB 3.0 controller port. However, the new USB 3.0 Type-B plug has been designed to only attach to USB 3.0 receptacles and devices.
ExtremeUSB was developed and patented by Icron Technologies to enable native USB connections to extend beyond the desktop, breaking through the 5m cable length limitation imposed by the USB standard. The ExtremeUSB® protocol manages the strict timing requirements of the USB specification to enable USB connections over any physical media.
What is “LEX” and “REX”?
LEX stands for Local Extender and REX stands for Remote Extender. These two units comprise a standard Icron Extension solution. The LEX unit interfaces to the Host PC via a Type-B USB connector, or a built-in Type-A USB cable. The LEX interfaces to the REX unit over the extension media (Cat 5e UTP, Fiber, etc.) and the REX unit provides connectivity for one or more USB devices at the remote location.
Can I daisy-chain ExtremeUSB® systems together for longer reach?
ExtremeUSB systems cannot be daisy-chained by connecting multiple systems in series (i.e. Local Extender to Remote Extender to Local Extender to Remote Extender).
Do my extenders need a driver?
ExtremeUSB is designed to be truly Plug-and-Play, and appears completely transparent to the host computer. No drivers are required.

Only the EL4500 USB and Video Extender can operate over a Local Area Network (LAN) or through a standard Ethernet hub or switch. The EL4500 operates at layer 2 (MAC layer) and does not require any TCP/IP overhead, thus it can’t operate through a router using the TCP/IP layer.
Why can I not select a support resolution when using my USB and Video Extender?
Either the latest video drivers are not installed, or the resolution is not supported. If the specific resolution is not listed by the monitors EDID, or is not supported by the USB and Video Extender, it will not operate.
What cable is recommended for best performance with the EL5100 or EL5200?
Icron recommends Cat 6/6a U/FTP or better cabling with solid core conductors and Cat 6/6a rated RJ45 jacks. That is, Cat 6 or 6a, with pair shielding. At minimum, standard Cat 5e UTP cable can be used but it must have solid core conductors and requires a very good environment and good installation practices, such as having no loops in the cable, ensure it is not placed near other cables or power lines, and that it is properly terminated with Cat 5e RJ45 jacks.
