3.1 REQUIREMENTS FOR INSTALLING THE EXTENDER
To complete the installation, you will also require the following items that are not included with this system:
USB compatible computer (host computer) with a USB compliant operating system
USB compatible device(s)
OM3 fiber optic cabling
3.2 FIBER OPTIC CABLING GUIDELINES
The Local and Remote Extenders are interconnected by fiber optic cabling. Duplex multimode fiber cabling is required for the extenders

3.7 CHECKING THE INSTALLATION
1. On the Local and Remote Extenders, check that the Power, Status, Link, USB 2 and USB 3 LEDs are on. If the Link LEDs are permanently
off, then the cabling between the Local and Remote Extender may not be installed properly or is defective.
2. For Windows users (XP, 7, 8, 8.1, 10), open Device Manager to confirm that the extender system has been installed correctly. Expand
the entry for Universal Serial Bus controllers by clicking the “+” sign. If the extender system has been installed correctly, you should find
two separate instances of “Generic SuperSpeed USB Hub” listed.
NOTE: To open Device Manager in Windows 7: Open the Start Menu, right click on “Computer” then select: Manage >> Device Manager
NOTE: To open Device Manager in Windows 8, 8.1 or 10: Right click the Start Menu and then select: Device Manager
3. For macOS users, open the System Profiler to confirm that the extender system has installed correctly. In the left-hand column under
Hardware, select “USB” and inspect the right-hand panel. If the extender has been installed correctly, you should find it listed as two
separate instances of “Hub” under the USB SuperSpeed Bus.
NOTE: To open System Profiler in macOS: Open the Finder, select Applications, then open the Utilities folder and double click on the
System Profiler icon.
4. If the extender system is not detected correctly or fails to detect, please consult the Troubleshooting section in this guide.
3.8 CONNECTING A USB DEVICE
1. Install any software required to operate the USB device. Refer to the documentation for the USB device, as required.
2. Connect the USB device to the device port on the Remote Extender.
3. Check that the device is detected and installed properly in the operating system.
3.9 COMPATIBILITY
The USB 3.1 Extender complies with USB 2.0 and USB 3.1 Gen 1 specifications governing the design of USB devices. However, there
is no guarantee that all USB devices or hosts will be compatible as there are a number of different characteristics that may impact the
operation of USB devices over extended distances.
