Requirements
To complete the installation, the following items (not included with this
package) are required:
USB compatible computer (host computer) with a USB compliant
operating system
USB compatible device
Cat 5e/6/7 Unshielded Twisted Pair (UTP) cable with two RJ-45
connectors (surface cabling), OR, Cat 5e/6/7 cabling with two information
outlets and two Cat 5e/6/7 patch cords with RJ-45 connectors (premise
cabling)
Network must be properly configured in order for full USB 2.0 throughput
to be realized and for maximum stability and reliability of your devices.
NOTE:
1. All references to Cat 5e cable in this document represent the minimum
requirement. Category 6 or better or STP cable may be substituted.
2. USB 3.0 devices will perform at USB 2.0 speeds if extended through the
UEH4102.
3. The cable distance between switches must be no greater than 100m if
CAT 5e/6/7 is used as the connection media.
4. Local Extender and Remote Extender to be on the same subnet.
5. Increasing the number of switches between the local and remote extender
may reduce the available bandwidth and as a result prevent some devices
from functioning properly.
6. Some networks may be configured to block devices with unfamiliar
MAC addresses. If this is the case, you will need to provide your network
administrator the MAC addresses of the local and remote extender units.
These can be found on the label on the bottom of each unit.

Hardware Setup
Cable Connection
To ensure proper operation, it is recommended that only Cat 5e or better,
Unshielded Twisted Pair (UTP) Ethernet cabling is used to connect the Local
unit to the Remote unit. The cable must have a straight-through conductor
configuration with no crossovers and must be terminated with 8 conductor
RJ-45 connectors at both ends. The combined length of any patch cords using
stranded conductors must not exceed 10 meters.
To set up your UEH4102 installation, refer to the installation diagram on
page 10 (the numbers in the diagrams correspond to the steps below), and do
the following:
1. Prepare two CAT 5e/6/7 patch cables (max. 100m) to the UEH4102L/R’s
rear panel Link port (RJ-45). Connect the other end to a Gigabit Ethernet
structure.
2. To power the UEH4102L, connect the included USB 2.0 cable to the USB
Type-B port on the rear panel of UEH4102L. Connect the other end to a
USB Type-A port of a computer.
3. Use the 4 USB 2.0 ports on UEH4102R to connect additional USB
peripheral devices.
4. To power the UEH4102R, plug an AC Adapter power cord into the Power
Jack on the rear panel of UEH4102R. Plug the other end into an
appropriate power source.
5. Check the front panel LEDs to monitor power, link, host, and activity.
6. Check the host computer to ensure all device drivers and software install
correctly.
1. Important safety information regarding the placement of this
device is provided on page 13. Please review it before
proceeding.
2. Make sure that the power to all devices connected to the
installation is turned off. You must unplug the power cords of
any computers that have the Keyboard Power On function.

Checking the Installation
After installing the hardware, use the information below to confirm all
peripheral devices are connected and working correctly.
1. On the Local (UEH4102L) and (UEH4102R) Remote units, check that the
Power, Host, and Link LEDs are on. If the Link LED is blinking, then the
network connection between the local and remote extender is not complete
or there may be faulty cabling, network components, misconfigured
network components, or the local and remote extender may need to be re-
paired (see the section Pairing the Local and Remote Extender on
page 12).
2. For Windows users (XP, 7, 8, 8.1, and 10), open Device Manager to
confirm that the UEH4102 has installed correctly. Expand the entry for
Universal Serial Bus controllers by clicking the + sign. If the UEH4102
has been installed correctly, you should find it listed as a “Generic USB
Hub”.
3. For Mac OS X users, open the System Profiler to confirm that the
UEH4102 has installed correctly. In the left hand column under Hardware,
select “USB” and inspect the right hand panel. If the UEH4102 has been
installed correctly, you should find it listed as a “Hub” under the USB
High-Speed Bus/USB Bus.
4. If the UEH4102 is not detected correctly or fails to detect, please consult
the Troubleshooting Guide.
Note: 1. To open System Profiler in OS X: Open the Finder, select
Applications, then open the Utilities folder and double click on the
System Profiler icon.
2. To open Device Manager in Windows 10, 8.1, 8, or 7: Left click Start.
Type “Device Manager” in the search box and tap Device Manager
on the menu.
3. To open Device Manager in Windows XP: On the desktop or in the
Start Menu, right-click on My Computer and select Properties. In the
System Properties window, click the Hardware tab. In the Hardware
tab, click the Device Manager button.

Pairing the Local and Remote Extender
If you purchased a complete system (a local extender and a remote extender
package), the UEH4102 extenders are paired out of the box.
If you wish to change the local and remote extender pairings across a network,
please do the following:
1. Ensure the local and remote extenders are either directly connected to each
other, or are connected to the same subnet on your network.
2. Press the Mode switch on the back of the local extender. The Link LED
will start blinking quickly to indicate that the local extender is now in
Pairing Mode.
3. Within 10 minutes, press the Mode switch on the back of the remote
extender. The Link LED will start blinking quickly to indicate that the
remote extender is now in Pairing Mode.
4. The Link LED on both units may start to blink slowly to indicate they are
trying to establish a link. If the link is established successfully, the Link
LEDs on both units will stay turned on.
Note: 1. After 10 minutes of inactivity in Pairing Mode, the extenders will
switch back to its regular mode and reestablish any previous links, if
any.
2. To cancel pairing mode, press and hold the Mode switch for less than
10 seconds.
Unpairing an Extender
If, for any reason, an extender needs to have its pairing removed, press and hold
the Mode switch for more than 10 seconds.

Troubleshooting
The UEH4102 complies with USB 1.1 and USB 2.0 specifications governing
the design of USB devices. However, ATEN does not guarantee that all USB
devices are compatible with the UEH4102, as there are a number of different
configurations that may impact the operation of USB devices over extended
distances.
Operation problems can be due to a variety of causes. The first step in solving
them is to make sure that all cables are securely attached and seated completely
in their sockets.
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.
