3.1 CABLING GUIDELINES
The USB 3.1 Extender requires a minimum grade of Category 6a cabling to be used in order to reach 328 feet (100 meters) of extension
distance.
NOTE: The total distance of 328 feet (100 meters) also includes the length of the patch cable if one is required. Up to 32.8 feet (10 meters)
of patch cable can be used, although the remaining 295 feet (90 meters) distance must consist of solid-core premise cabling.
Depending upon specific application requirements, we recommend that installers keep in mind how they intend to pull/route the link
cable and whether to use Shielded or Foiled cable where appropriate.
When installing this product, it is appropriate to use Unshielded (UTP) cabling if the cable run installation meets the following
requirements:
The cable is not bundled with other cables
The cable is run loosely with other Category cables
The cable is not placed close to sources of interference such as power lines and radios
The cable is not looped or coiled
When installing this product, Foiled (FTP) or Shielded (STP) cabling must be used if the cable run installation requires the following cable
run installation:
The cable is bundled with other cables
The cable is run tight against other Category cables
The cable is placed near sources of interference like power lines and radios
The cable is looped or coiled
NOTE: For best performance, install the USB 3.1 Extender using Shielded or Foiled CAT6a/7 cable.

3.2 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)
CAT6a/7 Unshielded Twisted Pair (UTP) cable with two RJ-45 connectors (if using surface cabling), or CAT6a/7 cabling with two
information outlets and two CAT6a/7 patch cords with RJ-45 connectors (if using premise cabling), ensuring the total cable length
does not exceed 328 feet (100 meters).

3.3 PREPARING YOUR SITE
Before installing the USB 3.1 Extender, you will need to prepare your site:
1. Place the computer where desired and set it up.
2. Locate your USB device(s) within the cable-length of the computer. If not, adjust the location of your device(s) and/or computer
accordingly.
NOTE: If you are using surface cabling, the USB 3.1 Extender supports a maximum distance of 328 feet (100 meters). Install the CAT6a/7
cabling as desired and terminate it with the appropriate RJ-45 ends. If using premise cabling, (in-building network infrastructure),
ensure your cabling is installed between the two locations and does not exceed 328 feet (100 meters) and that it meets the
CAT6a/7 specification.
Cable installation is important, particularly if high throughput applications are used. When installing, ensure the cable is installed away
from, or isolated from potential sources of interference such as electrical wiring, fluorescent lighting, etc.
NOTE: When terminating cables, ensure the matching RJ-45 connector is used for the cable type. For example, if CAT6a cable is used,
then CAT6a compatible RJ-45 connectors must be used. Otherwise, the benefits of using higher-grade cabling may not be
realized.
3.4 INSTALLING THE LOCAL EXTENDER
1. Place the Local Extender near the computer.
2. Assemble the power adapter and country specific power cord together and connect them into a suitable AC outlet.
3. Connect the supplied USB 3.1 Gen cable between the Local Extender host port and a USB 3 port on the host computer.
3.5 CONNECTING THE LOCAL EXTENDER TO THE REMOTE EXTENDER
With Surface Cabling:
1. Plug one end of the CAT 6a/7 cable (not included) into the Link port on the Local Extender.
2. Plug the other end of the CAT 6a/7 cable into the Link port on the Remote Extender.
With Premise Cabling:
1. Plug one end of a CAT 6a/7 patch cord (not included) into the Link port on the Local Extender.
2. Plug the other end of the patch cord into the CAT 6a/7 information outlet near the host computer.
3. Plug one end of the second CAT 6a/7 patch cord (not included) into the Link port on the Remote Extender.
4. Plug the other end of the patch cord into the CAT 6a/7 information outlet near the USB device.
NOTE: Do not exceed more than 32.8 feet (10 meters) total of patch cable when using premise cabling.
3.6 INSTALLING THE REMOTE EXTENDER
1. Place the Remote Extender near the USB device(s).
2. Assemble the power adapter and country-specific power cord together and connect them into a suitable AC outlet.
3. Connect the power adapter to the Remote Extender.

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 XP: Right click “My Computer” then select: Properties >> Hardware tab >> Device Manager
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.

APPENDIX B: TECHNICAL GLOSSARY
Category 6a/7 (CAT6a/7) Network Cabling: Category 6a/7 cable is commonly also referred to as CAT 6a or CAT 7. This cabling is
available in either solid or stranded twisted pair copper wire variants and as UTP (Unshielded Twisted Pair), FTP (Foiled Twisted Pair)
or STP (Shielded Twisted Pair). UTP cables are not surrounded by any shielding making them more susceptible to Electromagnetic
Interference (EMI). FTP/STP cables include shielding the copper wires and provide better protection against EMI.
USB 3 and USB 2.0 Cables: USB cables have two distinct full-sized connectors. The Type A connector is used to connect the cable
from a USB device to the Type A port on a computer or hub. The Type B connector is used to attach the USB cable to a USB device.

RJ-45: The Registered Jack (RJ) physical interface is what connects the network cabling (CAT6a/7) to the local unit and the remote
unit. You may use either the T568A scheme (see Table B-1 and Figure B-2) or the T568B scheme (see Table B-2 and Figure B-3) for
cable termination. RJ-45 connectors are sometimes also referred to as 8P8C connectors.
NOTE: Any given cable must be terminated using the same T568 scheme on both ends to operate correctly.
