INSTALLATION
CrystalLink USB2.0 CATx Extender Manual 6
Installation Procedure
Before beginning an installation, ensure you have all products and components ready for the installation
Figure 4. CrystalLink USB2.0 CATx extender – standard installation

Determine where the computer is to be located and set up the computer.

Determine where you want to locate the remote USB device(s).

Remember the product supports a maximum distance of 330ft (100m) for transparent USB devices. If
using patch (stranded) cables or premise wiring, the achievable extension distance may be less.

Avoid potential sources of interference such as electrical wiring, fluorescent lighting and radio
communications equipment.

Ensure that the CATx cable is terminated with matching connectors. For example, a CAT6 cable should
be terminated with compatible CAT6 connectors.
Installation Using Premise Wiring
If you are using premise cabling, ensure CATx cabling is installed between the two locations, with CATx
premise outlets located near both the computer and the USB device(s), and the total length, including patch
cords is not more than 330ft (100m).
Installing the Transmitter Unit

Place the transmitter unit near the computer.

Install the supplied USB cable between the transmitter and USB port on the host computer.
Installing the Receiver Unit
Place the receiver unit near the USB device(s) in the desired remote location.

CrystalLink USB2.0 CATx Extender Manual 7
Connecting the Transmitter to Receiver
To ensure optimum operation, it is recommended to use only solid core CATx UTP cabling to connect the
transmitter and receiver units. The cabling must have a straight-through conductor configuration with no
crossovers and must be terminated with 8 conductor RJ45 connectors at both ends. The combined length of
any patch cords using stranded conductors must not exceed 330ft (100m).
Connection Using Surface Cabling

Plug one end of the CATx cabling (not included) into the Link port (RJ45) on the transmitter unit.

Plug the other end of the CATx cabling into the Link port (RJ45) on the receiver unit.
Connection Using Premise Cabling

Plug one end of a CATx patch cord (not included) into the Link port (RJ45) on the transmitter unit.

Plug the other end of the patch cord into the CATx information outlet near the host computer.

Plug one end of the second CATx patch cord (not included) into the Link port (RJ45) on the receiver unit.

Plug the other end of the second patch cord into the CATx information outlet near the USB device.
Connecting a USB Device

Install any software required to operate the USB device(s). Refer to the documentation for the USB
device(s), as required.

Connect the USB device to the device port on the remote extender.

Check that the device is detected and installed properly in the operating system.
Checking the Installation
Check that the Power, Link, Host, and Activity LEDs are on at each end. If the Host or Link LEDs are
permanently off, then the cabling between the local and remote extenders may not be installed properly or is
defective.
For Windows users (XP, 7, 8, 10), open the Device Manager to confirm that the CrystalLink Extender has
installed correctly. Expand the entry for Universal Serial Bus controllers. If the CrystalLink Extender has been
installed correctly, you should find it listed as a “Generic USB Hub”.
For Mac OS X users, open the System Profiler (open the Finder, select Applications, open the Utilities folder
and select System Profiler) to confirm that the CrystalLink Extender has installed correctly. In the left-hand
column under Hardware, select “USB” and inspect the right-hand panel. If the CrystalLink Extender has been
installed correctly, you should find it listed as a “Hub” under the USB High-Speed Bus/USB Bus.
Compatibility
The CrystalLink USB2.0 CATx extender complies with USB 1.1 and USB 2.0 specifications governing the
design of USB devices. However, it is not possible to 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.

Troubleshooting Guide
The following table provides troubleshooting tips. The topics are arranged in the order in which they should be
executed in most situations. If you are unable to resolve the problem after following these instructions, please
contact Technical Support for further assistance.
Problem Cause Solution
ALL LEDs are OFF on the
transmitter.
The transmitter is not receiving
power from the USB port.
Ensure that the host computer is connected to
the transmitter.
Move the USB connector to another USB port
on the host computer.
ALL LEDs are OFF on the
receiver.
The transmitter is not receiving
power from the AC adapter.
Ensure that the host computer is connected to
the AC adapter.
Check the AC adapter is connected to a live
