Chapter 2: Overview
2. Overview
2.1 Introduction
Use CAT5 cable to extend connections to USB peripherals such as keyboards, mice, interactive whiteboards, and other devices
without the need for external power adapters. The extender is composed of two individual units: the local extender and the
remote extender.
The local extender receives power from the host computer, making it ideal for extensions in industrial control, sensor, or data
acquisition applications where you are short on power outlets. The extender supplies up to 400 mA to USB devices and is
industrial rated for ESD/EFT (electrostatic discharge/electrically fast transient) immunity.
Also, the extender’s remote unit has two downstream USB Type A ports for plugging in USB 1.1 or 2.0 devices. The extender
supports 130-foot (40 m) extensions over non-networked CAT5 cabling, but for some low-speed HID devices (keyboards and
mice, for instance), it can go as far as 278 feet (85 m).
You don’t need to add any software to your system or target devices. Simply attach the transmitter to your computer’s USB port,
plug in the CAT5 cable, attach the remote USB peripheral to the receiver, and begin transmitting.
2.2 Features
• Reliably extend USB 1.0 or 2.0 signaling over CAT5 cable to remote USB devices.
• Bus powered. No external AC adapter needed at either end.
• Industrial rated for ESD immunity.
• Supports both Full-Speed (12-Mbps) and Low-Speed (1.5-Mbps) throughput.
• Works with all major operating systems (Windows®, Mac OS X®, and Linux®).
• Includes 6-foot (1.8-m) USB cable for transmitter-to-host computer connection.
• Plug-and-play. No software drivers to load.
2.3 What’s Included
Your package should include the following items. If anything is missing or damaged, contact Black Box Technical Support
at 724-746-5500 or info@blackbox.com.

• (1) Remote Extender Unit
• (1) 6-ft. (1.8-m) USB 2.0 A–B cable
• Quick start guide
• To download this user manual, go to ftp://ftp.blackbox.com/anonymous/manuals/I/IC282A_rev1-USER.pdf.
2.4 What You Need to Supply
To complete the installation, you will require the following items that are not included:
• USB compatible computer (host computer) with a USB compliant operating system.

information outlets and two CAT5 patch cords with RJ-45 connectors (if using premise cabling)
NOTE: All references to CAT5 cable in this document represent the minimum cable requirement of solid-core CAT5e unshielded
twisted-pair cable. Or, you can substitute CAT6 or better or STP cable.

Chapter 3: Installation
3. Installation
3.1 Preparing Your Site
NOTE: The maximum extension length is reduced by 43.3 feet (13.2 m) for each USB hub added between the host computer and
the end device.
NOTE: Extender systems cannot be daisychained. An extender system can have only one local extender and one remote extender.
Follow these steps to prepare your site:
1. Determine where the host computer will be located and set up the computer.
2. Determine where you want to locate the remote USB device(s).
3. Make sure the cable run (including patch cables) between the host computer and the USB device(s) is no greater than 131 feet
(40 m).
3.2 Installing the Local Extender Unit
1. Place the local extender near the host computer.
2. Plug the supplied USB cable into the local extender and into an available USB port on the computer.
3.3 Installing the Remote Extender Unit
Place the remote extender near the USB device(s) at the desired remote location.
3.4 Connecting the Local Extender to the Remote Extender
If you are using surface cabling, follow these steps:
1. Plug one end of the CAT5 cable (not included) into the Link port (RJ-45) on the local extender.
2. Plug the other end of the CAT5 cable into the Link port (RJ-45) on the remote extender.
If you are using premise cabling, follow these steps:
1. Plug one end of a CAT5 patch cord (not included) into the Link port (RJ-45) on the local extender.
2. Plug the other end of the patch cord into the CAT5 information outlet near the host computer.
3. Plug one end of a second CAT5 patch cord (not included) into the Link port (RJ-45) on the remote extender.
4. Plug the other end of the second patch cord into the CAT5 (RJ-45) information outlet near the USB device.
3.5 Connecting a USB Device
1. On the host computer, install any software required to operate the USB device. If necessary, refer to the documentation for the
USB device(s).
2. Connect the USB device(s) to the device port(s) on the remote extender.

3. Directly connect the USB device to the host to verify
that the USB device operates correctly.
1. Connect the local extender to the remote extender
using a short cable.
2. Unplug the local extender from the host and wait
15 seconds. Then, plug the local extender back into
the host.
1. Connect the local extender to a different USB por t on
the host.
2. Connect a self-powered USB hub between the remote
extender and the USB device.
4.2 Contacting Black Box

Chapter 5: Technical Glossary
5. 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 that 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.
USB Type A USB Type A USB Type B USB Type B
Port connector Port connector
Figure 5-1. USB cables.
RJ-45 — The Registered Jack (RJ) physical interface is what connects the network cabling (CAT5) to the local extender and
remote extender. You may use either the T568A scheme (Table 5-2) or the T568B scheme (Table 5-3) for cable termination
because the extender uses all four pairs of the cable. RJ-45 connectors are sometimes also referred to as 8P8C connectors.
