Chapter 2: Overview  
2. Overview  
2.1 Introduction  
Extend USB signals as far as 330 feet (100 meters) to two remote USB 3.0 devices using secure, interference-free fiber cabling.  
The 2-Port USB 3.0 Fiber Extender uses multimode fiber optic cabling to extend device signals to remote areas of your factory,  
office, or security monitoring application.  
Compatible with the USB 3.0 or “SuperSpeed USB" standard, the extender boasts speeds up to 5 Gbps, about ten times that of  
USB 2.0. This way, you can extend your USB bus connections to newer USB 3.0 devices that use higher bandwidths and require  
bidirectional asynchronous, full-duplex data transfer. Plus, it supplies more power than USB 2.0 to the remote devices.  
With the higher data-transfer rate and power, the extender is ideal for connecting industrial USB 3.0 machine vision cameras,  
particularly those with high power sensors. It’s also great for post-production video editing and broadcast applications with USB  
3.0 peripherals and external USB CD/DVDs.  
The extender offers reliable operation with all USB 3.0 devices, including USB hubs. The local unit draws its power from the USB  
bus and the two-port remote unit receives its power from the included AC adapter.  
NOTE: The IC502A supports only USB 3.0 devices. USB 2.0 and 1.1 will not function through this extender. IC502A is NOT  
backward compatible with USB 2.0/1.1.  
2.2 Features  
• Ideal for linking to USB 3.0 security and industrial cameras, external DVD drives, and other high-bandwidth USB devices.  
• Extends USB 3.0 signals up 330 feet (100 m) over multimode fiber cable.  
• Transfers at 5-Gbps speeds—ten times faster than USB 2.0.  
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 [email protected].  
• (1) Local Extender Unit  
• (1) Remote Extender Unit  
• (1) Remote Extender AC power adapter  
• (1) USB 3.0 cable  
• (1) U.S. power cable  
• Quick start guide

Chapter 3: Installation  
3. Installation  
3.1 Requirements  
To complete installation of the IC502A, you will also require the following items that are not included with the product:  
• USB 3.0 compatible computer (host computer) with a USB 3.0 compliant operating system.  
• USB 3.0 compatible device.  
• Two-strand 50-/125-μm multimode fiber (MMF) optic cable with duplex LC connectors.  
NOTE: The maximum length of the multimode fiber (MMF) optic cable supported by the IC502A system, including patch cords, is  
330 feet (100 m) for USB 3.0 cameras, and 165 ft. (50 m) for other devices.  
3.2 Fiber Optic Link Cabling  
The Local Extender and Remote Extender are interconnected by fiber optic cabling. This cabling must be:  
• 50-/125-μm multimode fiber (MMF).  
• Terminated with Duplex LC connectors.  
The extender can achieve the following maximum distances, depending on the application and cabling standard:  
• Using OM3, reach up to 330 feet (100 m) with USB 3.0 cameras, and up to 165 feet (50 m) for all other applications.  
• Using OM2, reach up to 165 feet (50 m) for all applications.  
NOTE: For help sourcing appropriate fiber optic cabling, contact Black Box Technical Support at 724-746-5500 or  
If premise cabling will be used for the installation, then the distances provided above must be met when measuring from Local  
Extender to Remote Extender, including the premise cabling and the patch cables. All cables must meet the ratings specified.  
Patch cables must be terminated with Duplex LC connectors.

Extender.  
3.6 Installing the Local Extender  
1. Place the Local Extender near the computer.  
2. Connect the link cable to the Local Extender and the Remote Extender.  
With surface cabling:  
• Plug one end of the fiber optic cabling (not included) into the Link port on the Local Extender.  
• Plug the other end of the fiber optic cabling into the Link port on the Remote Extender.  
With premise cabling:  
• Plug one end of a fiber optic patch cord (not included) into the Link port on the Local Extender.  
• Plug the other end of the patch cord into the fiber optic information outlet near the host computer.  
• Plug one end of the 2nd fiber optic patch cord (not included) into the Link port on the Remote Extender.  
• Plug the other end of the 2nd patch cord into the fiber optic information outlet near the USB device.  
3. Install the supplied USB 3.0 cable between the Local Extender and a USB 3.0 port on the host computer.  
CAUTION: The IC502A will not operate on a USB 2.0 port; make sure you connect to a USB 3.0 port. The USB 3.0 port will have a  
blue connector inside, whereas a USB 2.0 port will typically have a black connector inside.

Chapter 3: Installation  
3.7 Checking the Installation  
1. On the Local and Remote Extenders, check that the Power, Status, and Host LEDs are on and solid. If the Host or Status LEDs  
are permanently off, then the cabling between the Local and Remote Extender may not be installed properly or is defective.  
2. For Windows® users, open “Device Manager” to confirm that the IC502A has installed correctly. Expand the entry for Universal  
Serial Bus controllers by clicking the + sign. If the IC502A has been installed correctly, you should find it listed as two  
“Superspeed Hubs,” or “3.0 Hubs.”  
Figure 3-11. Hubs listed screen, Windows operating system.  
3. For Mac OS X® users, open the System Profiler to confirm that the IC502A has installed correctly. In the left hand column under  
Hardware, select “USB” and inspect the right-hand panel. If the IC502A has been installed correctly, you should find it listed as  
a “Hub” under the USB SuperSpeed Bus.  
Figure 3-12. Hubs listed screen, Mac operating system.  
4. If the IC502A is not detected correctly or fails to detect, please consult the “Troubleshooting” section in this guide.  
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.  
NOTE: To open Device Manager in Windows 8 or Windows 7: Open the “Start” menu, right-click on “Computer,” then select  
“Manage >> Device Manager.”

3.8 Compatibility  
The IC502A complies with the USB 3.0 specification. However, Black Box Corporation does not guarantee that all USB 3.0 devices  
are compatible with the IC502A, because there are a number of different configurations that may impact the operation of USB  
3.0 devices over extended distances.  
CAUTION: The IC502A supports only USB 3.0 devices. USB 2.0 and 1.1 devices will not function through this extender.

4. Troubleshooting  
4.1 Troubleshooting Tips  
The following section 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, contact Black Box Technical Support  
at 724-746-5500 or [email protected] for further assistance.  
Problem: All LEDs on the Local Extender are off.  
Cause: The Local Extender is not receiving power from the USB port or the (optional) Local Extender AC adapter.  
Solution(s):  
1. Make sure that the USB connection between the Local Extender and host computer is properly installed.  
2. Move the USB connector to another USB port on the host computer.  
Problem: All LEDs on the Remote Extender are off.  
Cause: The Remote Extender is not receiving power from the AC adapter.  
Solution(s):  
1. Make sure 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.  
Problem: Status LEDs on both the Local and Remote Extenders are blinking.  
Cause(s):  
1. There is no connection between the Local Extender and Remote Extender.  
2. The Local Extender is not connected to a USB 3.0 port.  
3. The host computer does not support USB 3.0.  
Solution(s):  
1. Make sure that the host computer supports USB 3.0; refer to manual for the computer to confirm.  
2. Make sure the Local Extender is connected to a USB 3.0 port. The center of the port should be blue. Another color, such as

A.1 USB Connectors  
USB cables have two classes of connectors. The Type A connectors are used to connect the cable from a USB device to a Type A  
port on a computer or hub. The Type B connectors are used to attach the USB cable from a USB host to a USB device or hub.  
There are full-sized, mini, and micro variants of both type A and B connectors.  
USB 3.0 introduces changes to the connectors. USB 3.0 and USB 2.0 Type A connectors are the same shape and size and are  
compatible with each other. However, the USB 3.0 Type B connector will not fit in a USB 2.0 Type B port, though a USB 2.0 Type  
B connector will fit into a USB 3.0 Type B port.
