Installation guide
Before you can install the UEH4002, you need to prepare your site:
1. Determine where the computer is to be located and set up the computer.
2. Determine where you want to locate the USB device(s).
3. If you are using surface cabling, the UEH4002 supports a maximum distance of 100m.
OR
If you are using premise cabling, ensure Cat 5 cabling is installed between the two locations,
with Cat 5 information outlets located near both the computer and the USB device(s), and
the total length, including patch cords is no more than 100m.
Installing the Local unit
1. Place the Local unit near the computer.
2. Install the supplied USB cable between the Local and USB port on the host computer.
Installing the Remote unit
1. Place the Remote unit near the USB device(s) in the desired remote location.
2. Plug the power adapter into a suitable AC outlet.
3. Connect the power adapter to the Remote unit.
6
USB extension up to 100m Cat 5 (or better) cable

Connecting the Local unit to the Remote unit
To ensure proper operation, it is recommended that only Cat 5 or better, Unshielded Twisted Pair (UTP) cabling
be used to connect the Local unit to the Remote unit.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 10m.
With Surface Cabling
1. Plug one end of the Cat 5 cabling (not included) into the Link port (RJ45) on the Local unit.
2. Plug the other end of the Cat 5 cabling into the Link port (RJ45) on the Remote unit.
With Premise Cabling
1. Plug one end of a Cat 5 patch cord (not included) into the Link port (RJ45) on the Local unit.
2. Plug the other end of the patch cord into the Cat 5 information outlet near the host computer.
3. Plug one end of the 2nd Cat 5 patch cord (not included) into the Link port (RJ45) on the Remote unit.
4. Plug the other end of the 2nd patch cord into the Cat 5 information outlet near the USB device.
Checking the Installation
1. On the Local and Remote units, check that the Power, Host, and Link LEDs are on and that the Activity LED
is blinking. If the Link LED is permanently off, then the cabling between the Local and Remote unit is not
installed properly or is defective.
2. For Windows users (2000, XP,Vista,Windows 7), open Device Manager to confirm that the UEH4002
has installed correctly. Expand the entry for Universal Serial Bus controllers by clicking the
+ sign. If the UEH4002 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 UEH4002 has installed correctly.
In the left hand column under Hardware, select “USB”and inspect the right hand panel. If the UEH4002
has been installed correctly, you should find it listed as a “Hub”under the USB High-Speed Bus/
USB Bus.
4. If the UEH4002 is not detected correctly or fails to detect, please consult the Troubleshooting
Guide.
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.
To open Device Manager in Windows 2000 or XP:
Right click “My Computer”then select: Properties >> Hardware tab >> Device Manager
To open Device Manager in Windows Vista or Windows 7:
Open the Start menu, right click on “Computer”then select: Manage >> Device Manager

Connecting a USB Device
1. Install any software required to operate the USB device(s). Refer to the documentation for the USB
device(s), as required.
2. Connect the USB device to the device port on the Remote unit.
3. Check that the device is detected and installed properly in the operating system.
Compatibility
The UEH4002 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 UEH4002, as there are a
number of different configurations 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. If you are unable to resolve the problem after following these instructions,
please contact technical support for further assistance.
PROBLEM CAUSE SOLUTION
All LEDs on Local
unit are off.
•The Local unit is not receiving
enough power from the USB
port or the (optional) Local AC
adapter.
1. Ensure that the USB connection between the
local and host computer is properly installed.
2. Move the USB connector to another
USB port on the host computer.
All LEDs on
Remote unit are
off.
•The Remoteunit is not receiving
power from the AC adapter.
1. Ensure that the AC power adapter is properly
connected to the Remote unit.
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
Local and
Remote are off.
•There is no connection between
the Local unit and Remote unit.
1. Ensure Cat 5 cable is connected between the
Local unit and Remote unit. Cat 5 or better cable,
UTP with a straight through connector and no
crossovers, and 8 connector RJ45 connectors are
used at both ends.
2. If the Cat 5 cable is defective, connect a short
Cat 5 patch cord between the Local unit and
Remote unit to determine if the original Cat 5
cable is defective.

computer operating system prior to attaching
the USB device to the Remote unit. Please see your
USB device manufacturer’s website for details.
2. 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
(500mA).
1. Power cycle Remote.
LED Host and
LINK LEDs
on Local/Remote
units blink
intermittently.
•Firmware mismatch between
the Local and Remote.

Technical Glossary
Category 5 (Cat 5) Network Cabling
Category 5 cable is commonly also referred to as Cat 5. This cabling is available in either solid or stranded
twisted pair copper wire variants and as UTP (Unshielded Twisted Pair) or STP (Shielded Twisted Pair). UTP
cables are not surrounded by any shielding making them more susceptible to electromagnetic interference
(EMI). STP cables include shielding over each individual pair of copper wires and provides better protection
against EMI. Category 5 has been superseded by Cat 5e cabling which includes improved data integrity to
support high-speed communications.
USB Cables
USB cables have two distinct connectors.The Type A connector is used to connect the cable from a USB
device to the Type A port on a computer or hub.The Type B connector is used to attach the USB cable to a
USB device.
RJ45
The Registered Jack (RJ) physical interface is what connects the network cabling (Cat 5) to the Local unit and
Remote unit.You may use either the T568A scheme (Table 1) or the T568B scheme (Table 2) for cable termination
as the UEH4002 uses all four pairs of the cable. RJ45 connectors are sometimes also referred to as 8P8C
connectors.
