Instruction Manual
10
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, miscongured 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”.

Instruction Manual
11
3. Mac OS: Open the System Proler to conrm 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 Proler in OS X: Open the Finder, select Applications, then open the
Utilities folder and double click on the System Proler 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 specications. However, there is
no guarantee that all USB devices or hosts will be compatible with the USB2G4LEXT2,
as there are a number of dierent 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.
All LEDs on
the Remote
Extender are
o.
• The Remote
Extender is not
receiving power
from the AC adapter.
1. Ensure that the AC power adapter is
properly connected to the Remote
Extender.
2. Check that the AC adapter is
connected to a live source of electrical
power. Check that the Remote power
LED is illuminated.
Link LEDs on
the Local and
the Remote
Extenders are
o.
• There is no
connection between
the Local and
Remote Extenders.
1. Ensure Cat 5e cable is connected
between the Local and Remote
Extenders. Cat 5e or better cable, UTP
with a straight through connector and
no crossovers, and 8 conductor RJ45
connectors are used at both ends.
2. Connect a short Cat 5e patch cord
between the Local and Remote
Extenders to determine if the original
Cat 5e cable is defective.

network switches.
2. Re-pair the units together.
3. Ensure the network switches can
communicate with each other and are
on the same subnet.
4. Ensure the network switches are not
blocking trac from the extenders
either based on MAC address or due
to trac patterns.
5. Consult with your network
administrator.
