Verifying Installation
1. On the Local and Remote Extender, check that the Power, Status, Link and Host LEDs
are on.
Note: For direct connect, if the Host or Link LEDs are permanently o, then the
cabling between the Local and Remote Extender may not be installed properly or is
defective.
For network connect, if the Link LED is blinking, then the network connection
between the Local and Remote Extender is not complete and there may be faulty
cabling, network components, miscongured network components, or the Local
and Remote Extender may need to be re-paired together (see the section on pairing
a Local and Remote Extender).
2. Windows: Open the Device Manager by right-clicking on Computer, and then
select Manage. In the new Computer Management window, select Device Manager
from the left window panel (For Windows 8, open the Control Panel and select
Device Manager).
Expand the entry for Universal Serial Bus controllers by clicking the “+” sign. If the
USB2G4LEXT2 has been installed correctly you should nd it listed as a “Generic
USB Hub”.
Page 14
Instruction Manual
11
3. Mac OS: Open the System Proler to conrm that the USB2G4LEXT2 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 nd it listed as a
“Hub” under the USB High-Speed Bus/USB Bus.
To open System Proler in OS X: Open the Finder, select Applications, then open the
Utilities folder and double click on the System Proler icon.
Pairing and Unpairing
Pairing the Local and Remote Extender
The extenders will be paired with each other out of the box, so no pairing action
should be required. However, if you wish to change the Local and Remote Extender
pairings across a network, then the following steps must be taken:
1. Ensure the Local and Remote Extender are directly connected to each other, or are
connected to the same subnet on your network.
2. Press and hold the Pairing button on the back of the Local Extender. Release the
button within 10 seconds. The Link LED will start ashing.
3. Within 10 minutes of activating the pairing mode on the Local Extender, press and
hold the Pairing button on the back of the Remote Extender. Release the button
within 10 seconds. The Link LED will start ashing.
4. The Link LED on both units may start ashing more slowly before nally turning on.
Once the Link LEDs are solid, the link is established between both extenders.
Note: If more than 10 minutes pass before the units are paired, then the extenders
will switch back to regular mode and reestablish the previous links they had, if any. To
cancel pairing mode, press and hold the Pairing button a second time. Release it within
10 seconds.
Unpairing an Extender
If for any reason an extender needs to have its pairing removed, this can be done
by pressing and holding the Pair button for longer than 10 seconds. Once this is
completed the unit will not be paired to any other extender.

Compatibility
The USB2G4LEXT2 complies with USB 1.1 and USB 2.0 specications. However, there is
no guarantee that all USB devices or hosts will be compatible with the USB2G4LEXT2,
as there are a number of dierent characteristics that may impact the operation of USB
devices over extended distances.
Troubleshooting
The following table provides troubleshooting tips. The topics are arranged in the order
in which they should be executed in most situations.
Problem Cause Solution
All LEDs on
the Local
Extender are
o.
• The Local Extender
is not receiving
power from the
USB port.
1. Ensure that the host computer is
connected to the Local Extender.
2. Move the USB connector to another
USB port on the host computer.
