FIGURE 3-1. INSTALLATION DIAGRAM
3.1 PREPARING FOR 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 1640 feet (500 meters) over multimode fiber
or 6.2 miles (10 km) over single-mode fiber.
OR
If you are using premise cabling, ensure that compatible fiberoptic cable is installed between the two locations and the total does not
exceed the specified distance.
3.2 INSTALLING THE LOCAL EXTENDER
1. Place the local extender near the computer.
2. Install the supplied USB cable between the local extender and USB port on the host computer.
3.3 INSTALLING THE REMOTE EXTENDER
1. Place the remote extender near the USB device(s) in the desired remote location.
2. Assemble the power adapter and country-specific power cord together and connect them into a suitable AC outlet.
3. Connect the power adapter to the remote extender.
CAUTION: Use only the AC adapter supplied with the Extender. Use of substitute adapters may cause permanent damage to the system
and will void the warranty.

CHAPTER 3: INSTALLATION
3.4 CONNECTING THE LOCAL EXTENDER TO THE REMOTE EXTENDER
WITH SURFACE CABLING:
1. Plug one end of the fiberoptic cabling (not included) into the Link port on the local extender.
2. Plug the other end of the fiberoptic cabling into the Link port on the remote extender.
WITH PREMISE CABLING:
1. Plug one end of a fiberoptic patch cord (not included) into the Link port on the local extender.
2. Plug the other end of the patch cord into the fiberoptic information outlet near the host computer.
3. Plug one end of the second fiberoptic patch cord (not included) into the Link port on the remote extender.
4. Plug the other end of the second patch cord into the fiberoptic information outlet near the USB device.
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 remote extender.
3. Check that the device is detected and installed properly in the operating system.
3.6 CHECKING THE INSTALLATION
1. On the local and remote extenders, check that the Power, Activity, Link, and Host LEDs are on. If the Host or Link LEDs are permanently
off, then the cabling between the local and remote extenders may not be installed properly or is defective.
2. For Windows users (XP, 7, 8, 8.1, 10), open Device Manager to confirm that the Extender extender system has been installed correctly.
Expand the entry for Universal Serial Bus controllers by clicking the “+” sign. If the extender system has been installed correctly, you
should find it listed as a “Generic USB Hub.”
TO OPEN DEVICE MANAGER IN WINDOWS XP:
Right-click “My Computer” then select: Properties >> Hardware tab >> Device Manager.
TO OPEN DEVICE MANAGER IN WINDOWS 7:
Open the Start Menu, right-click on “Computer” then select: Manage >> Device Manager.
TO OPEN DEVICE MANAGER IN WINDOWS 8, 8.1, OR 10:
Right-click the Start Menu and then select: Device Manager .
3. For Mac OS users, open the System Profiler to confirm that the Extender Series extender system 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.
TO OPEN SYSTEM PROFILER IN MAC OS:
Open the Finder, select Applications, then open the Utilities folder and double-click on the System Profiler icon.
4. If the Extender Series extender system is not detected correctly or fails to detect, consult the Troubleshooting section in this guide.

3.7 COMPATIBILITY
The Extender complies with USB 1.1 and USB 2.0 specifications governing the design of USB devices. However, there is no guarantee that
all USB devices will be compatible, as there are a number of different factors that may impact the operation of USB devices over extended
distances.
3.8 USB EXTENDER MOUNTING (OPTIONAL)
The bottom of the enclosure features four convenient pre-drilled holes for optional mounting. Based on your requirements, choose
from two available mounting options:
1. USB Extender Mounting Kit (purchased separately, part number IC400MK)
2. USB Extender Direct Surface Mounting (using your own hardware)
OPTION 1: USB EXTENDER MOUNTING KIT (PART NUMBER IC400MK, ORDERED SEPARATELY)
Each kit includes:
(2) mounting brackets
(4) M3.0 locking washers
(4) M3.0 x 5-mm Phillips pan head screws
Mounting bracket installation guide (see diagram below)
NOTE: One kit is required to mount per Local Extender or Remote Extender.
Using a Phillips screwdriver, in the order as illustrated below, fasten and secure the provided screws, locking washers and brackets
into place.

CHAPTER 3: INSTALLATION
Once the bracket mounting is secured onto the extender, it is ready for mounting onto a surface. Please note you will need to
provide your own screws to secure the extender using the available slots on each bracket.
OPTION 2: USB EXTENDER DIRECT SURFACE MOUNTING (USING YOUR OWN HARDWARE)
The bottom of the enclosure features four pre-drilled holes for optional surface mounting.

Distance between the
enclosure mounting holes:
42.0 mm x 77. 0 mm
FIGURE 3-3. DIRECT SURFACE MOUNTING
1. Mark the center point of each of the four holes on your mounting surface either by directly measuring or using a printout
of the stencil below.
2. Hardware recommendation: M3.0 locking washers and M3.0 screws (4 of each per extender) noting screw length will depend
upon thickness of mounting surface.
3. Drill through each of the four hole markings on the mounting surface using a 4.7625-mm (3/16”) drill bit.
4. Align the bottom enclosure holes to the newly drilled out holes on the mounting surface.
5. Place a locking washer on each of the four screws and using a screwdriver, fasten the extender into place.
To ensure the stencil below prints to scale be sure to set the page scaling setting to “none”.

PROBLEM CAUSE SOLUTION
All LEDs on both the local and remote
extenders are on, but the USB device does
not operate correctly, or is detected as an
“Unknown Device” in the operating system.
The USB device is malfunctioning.
The computer does not recognize the
USB device.
The application software for the
device is not operating.
The extender is malfunctioning.
1. Disconnect the extender from the computer.
