INSTALLATION
CrystalLink USB2.0 Fiber 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 fiber 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 6.2 miles (10Km) 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 fiber cable is terminated with Duplex LC type matching connectors. Two strands of multimode
fiber cabling are required for the multimode extender up to 1,640ft (500m) using 50/125μm or up to 902ft
(275m) using 62.5/125μm fiber optic cable.
Installation Using Premise Wiring
If you are using premise cabling, ensure fiber cabling is installed between the two locations, with fiber premise
outlets located near both the computer and the USB devices.
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.

Connecting the Transmitter to Receiver
To ensure optimum operation, it is recommended to use Duplex LC fiber cabling to connect the transmitter and
receiver units.
Connection Using Surface Cabling

Plug one end of the fiber cabling (not included) into the Link port on the transmitter unit.

Plug the other end of the fiber cabling into the Link port on the receiver unit.
Connection Using Premise Cabling

Plug one end of a fiber patch cord (not included) into the Link port on the transmitter unit.

Plug the other end of the patch cord into the fiber information outlet near the host computer.

Plug one end of the second fiber patch cord (not included) into the Link port on the receiver unit.

Plug the other end of the second patch cord into the fiber 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 fiber 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
CrystalLink USB2.0 Fiber Extender Manual 9
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
source of electrical power. Check that the
POWER LED on the receiver is illuminated.
LINK LEDs on the
transmitter and receiver
are OFF.
There is no connection
between the transmitter and
receiver.
Ensure that fiber cabling is connected between
the transmitter and receiver.
Connect a short fiber patch cable between the
transmitter and receiver. Recheck the link
status. If the LINK LED is now SOLID ON, the
previous cable is defective or not capable of
supporting the link.
LINK LED on the transmitter
is ON, HOST LED on the
transmitter is OFF.
The host computer is not
powered on.
The transmitter is not
connected to a computer.
The host computer does not
support USB Hubs.
The unit is malfunctioning.
Disconnect all USB devices from the receiver.
Disconnect transmitter from the host
computer.
Disconnect AC adapter from the receiver.
Reconnect the transmitter to the host
computer.
Reconnect the AC adapter to the receiver.
Check that the extender has enumerated as a
USB hub in Windows Device Manager, MacOS
System Profiler or using “Isusb” command in a
Linux Terminal.
If the problem is not resolved, contact
Technical Support.
Both extenders were
working, but then the Host
LED on remote extender
unit is suddenly blinking.
•The remote extender is in
suspend mode. The operating
system may put the extender
in suspend mode when the
computer is put into a
suspend/standby state or when
no USB device(s) are attached.
•Recover/resume the operating system from
suspend/standby mode (see your operating
system’s documentation).
•Attach a new USB device to the extender.

CrystalLink USB2.0 Fiber Extender Manual 10
Problem Cause Solution
All LEDs on both the local
and remote extenders are
on, but the USB device
does not operate
correctly, or is detected
as an “Unknown Device”
in the operating system.
•The USB device is
malfunctioning.
•The computer does not
recognize the USB device.
•The application software for the
device is not operating.
•The extender is malfunctioning.
•Disconnect the extender from the computer.
•Connect the USB device directly to the USB
port on the computer.
•If the device does not operate properly,
consult the user documentation for the device.
•Update your system BIOS, chipset or USB Host
controller drivers from your System/Mother
board manufacturer’s website.
•If the device operates properly when directly
connected to the computer, connect another
device (of a different type) to the extender.
•Connect the extender to the computer.
•If the second device does not operate, the
extender system may be malfunctioning.
•Contact technical support for assistance.
•If the second device does operate properly,
the first device may not be compatible with the
extender.
USB device is attached to
remote extender’s USB
port, but remote extender
device LED is off.
A USB device must have the
appropriate driver installed on the
computer operating system.
•Install the required USB device driver on the
computer operating system prior to attaching
the USB device to the remote extender. Please
see your USB device manufacturer’s website
for details.
•Consult your USB device documentation and
power your USB device with the additional,
USB device manufacturer supplied, power
supply (if available).
Device LED is orange and
units are no longer
functioning.
Overcurrent condition has
occurred because USB device
draws more power than can be
supplied per USB specification (1
Amp).
•Power cycle remote extender.
LED Host and LINK LEDs
on local and remote
extenders blink
intermittently.
Firmware mismatch between the
local and remote extenders.
•Use a different local and remote extender pair
which have the same firmware revision.
•Upgrade the local and remote extender
firmware, contact technical support for
assistance.
