2. Overview  
2.1 Introduction  
The 1-Port CAT5 USB 2.0 Extender increases the distance from your computer to  
a wide variety of USB devices—from printers, scanners, hard drives, and audio  
devices to touchscreens, Web cams, and game controllers. USB devices can be  
located up to 100 meters (330 feet) from the computer. The extender is  
composed of two individual units: the Local Extender (LEX) unit and the Remote  
Extender (REX) unit.  
The instructions in this guide assume a general knowledge of computer  
installation procedures, familiarity with cabling requirements, and some  
understanding of USB devices.  
NOTE: Notes provide additional information that could be useful.  
CAUTION: Cautions provide important information about an operational  
requirement.  
2.2 Features  
• Extends USB 2.0 high-speed and USB 1.1 (low-speed, full-speed) devices up to  
330 feet (100 m) over CAT5 cable.  
• Operates with USB 2.0 high-speed host controllers and USB 1.1 classic hosts.  
• Supports all USB device types: Control, Interrupt, Bulk, and Isochronous at up to  
480 Mbps.  
• True plug-and-play, ready to operate right out of the box. No new driver  
installation required.  
• Supports all major operating systems, including Windows®, Mac® OS, and  
Linux®.  
• Provides (1) remote USB 2.0 port. Number of devices can be increased using  
additional USB hubs.  
• AC power adapter at remote extender unit supplies standard 500 mA to USB  
port.  
• Power adapter at local extender unit is not required for normal operation.

Chapter 3: Installation  
3. Installation  
Before you can install the extender, 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 extender supports a maximum distance of  
330 feet (100 m).  
OR  
If you are using premise cabling, ensure CAT5 cabling is installed between the  
two locations, with CAT5 information outlets located near both the computer  
and the USB device(s), and the total length, including patch cords, is no more  
than 330 feet (100 m).  
3.1 Installing the Local Extender (LEX) Unit  
1. Place the LEX unit near the computer.  
2. Install the supplied USB cable between the LEX and USB port on the host  
computer.  
3.2 Installing the Remote Extender (REX) Unit  
1. Place the REX 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 REX unit.  
3.3 Connecting the Local Extender (LEX) Unit to the Remote Extender  
(REX) Unit  
NOTE: For proper operation, we recommend that you use only CAT5 or better,  
Unshielded Twisted Pair (UTP) cabling to connect the LEX unit to the REX  
unit. The cabling 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 32.8 feet (10 m).  
With Surface Cabling:  
1. Plug one end of the CAT5 cabling (not included) into the Link port (RJ-45) on  
the LEX unit.  
IC401A User Manual  
Page 14  
724-746-5500 | blackbox.com  
Chapter 3: Installation  
2. Plug the other end of the CAT5 cabling into the Link port (RJ-45) on the REX  
unit.  
With Premise Cabling:  
1. Plug one end of a CAT5 patch cord (not included) into the Link port (RJ-45) on  
the LEX unit.  
2. Plug the other end of the patch cord into the CAT5 information outlet near the  
host computer.  
3. Plug one end of the second CAT5 patch cord (not included) into the Link port  
(RJ-45) on the REX unit.  
4. Plug the other end of the second patch cord into the CAT5 information outlet  
near the USB device.  
3.4 Checking the Installation  
1. On the LEX and REX 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 LEX and REX unit is not installed properly or is defective.  
2. For Windows users (2000, XP, Vista, Windows 7), open Device Manager to  
confirm that the extender has installed correctly. Expand the entry for Universal  
Serial Bus controllers by clicking the + sign. If the extender 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 extender 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 find it listed as a “Hub” under the USB High-Speed Bus/USB Bus.  
4. If the extender is not detected correctly or fails to detect, consult Section 4,  
Troubleshooting.  
NOTE: 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.

3.5 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 REX unit.  
3. Check that the device is detected and installed properly in the operating  
system.  
3.6 Compatibility  
The extender complies with USB 1.1 and USB 2.0 specifications governing the  
design of USB devices. However, we do not guarantee that all USB devices are  
compatible with the extender, because there are a number of different  
configurations that may impact the operation of USB devices over extended  
distances.

Appendix: Technical Glossary  
Appendix. Technical Glossary  
Category 5 (CAT5) Network Cabling — Category 5 cable is commonly also  
referred to as CAT5. 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 CAT5e 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.  
Figure 6-1. USB connectors.  
RJ-45 — The Registered Jack (RJ) physical interface is what connects the network  
cabling (CAT5) to the LEX unit and REX unit. You may use either the T568A  
scheme (Table 6-1) or the T568B scheme (Table 6-2) for cable termination. The  
1-Port CAT5 USB 2.0 Extender uses all four pairs of the cable. RJ-45 connectors  
are sometimes also referred to as 8P8C connectors.
