Installation Guide
Installing the USB 3-2-1 Raven 3124 System
Requirements
To complete the installation, you will also require the following items that are not included with this system:
• USB compatible computer (host computer) with a USB compliant operating system
• USB compatible device(s)
• OM3 Fiber optic cabling
Fiber Optic Link Cabling
The LEX and REX extenders are interconnected by fiber optic cabling. Duplex multimode ber cabling
is required for the Raven 3124 for extending up to 200m using 50/125μm OM3 grade cable. The cabling
subsystem must provide a duplex connection with crossover, and must be terminated with Duplex LC
connectors at both ends.

Optional Network Connections
Preparing Your Site
Before installing the Raven 3124 extender, you will need to prepare your site:
1. Place the computer where desired and set it up.
2. Ensure to locate the USB device(s) within the cable-length of the computer. If not, adjust the
location of the device(s) and/or computer accordingly.
3. If you are using surface cabling, the Raven 3124 supports a maximum distance of 200m over OM3
multimode ber.
4. If using premise cabling, ensure compatible ber optic cabling is installed between the two locations
and does not to exceed the specied distance.
6
Installing the LEX Unit
1. Place the LEX unit near the computer.
2. Assemble the power adapter and country specic power cord together and connect them into a
suitable AC outlet.
3. Connect the supplied USB 3.1 Gen cable between the LEX host port and a USB 3 port on the host
computer.
Connecting the LEX to the REX
With Surface Cabling:
1. Plug one end of the ber optic cabling (not included) into the Link port on the LEX.
2. Plug the other end of the ber optic cabling into the Link port on the REX.
With Premise Cabling:
1. Plug one end of a ber optic patch cord (not included) into the Link port on the LEX.
2. Plug the other end of the patch cord into the ber optic information outlet near the host computer.
3. Plug one end of the second ber optic patch cord (not included) into the Link port on the REX.
4. Plug the other end of the second patch cord into the ber optic information outlet near the USB
device.
Installing the REX Unit
1. Place the REX near the USB device(s).
2. Connect the power adapter to the REX.
Checking the Installation
1. On the LEX and REX units, check that the Power, Status, Link, USB 2 and USB 3 LEDs are on. If
the Link LEDs are permanently o, then the cabling between the LEX and REX units may not be
installed properly or is defective.
2. For Windows users (XP, 7, 8, 8.1, 10), open Device Manager to conrm that the 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 two separate instances of
“Generic SuperSpeed USB Hub” listed.
To open Device Manager in Windows XP:
note
Right click “My Computer” then select: Properties >> Hardware tab >> Device Manager
To open Device Manager in Windows 7:
note
Open the Start Menu, right click on “Computer” then select: Manage >> Device Manager
To open Device Manager in Windows 8, 8.1 or 10:
note
Right click the Start Menu and then select: Device Manager

3. For macOS users, open the System Profiler to conrm that the 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 two separate instances of “Hub”
under the USB SuperSpeed Bus.
To open System Profiler in macOS:
note
Open the Finder, select Applications, then open the Utilities folder and double click on the System Proler icon.
4. If the extender system is not detected correctly or fails to detect, please consult the Troubleshooting
section in this guide.
Connecting a USB Device
1. Install any software required to operate the USB device. Refer to the documentation for the USB
device, as required.
2. Connect the USB device to the device port on the REX.
3. Check that the device is detected and installed properly in the operating system.
Compatibility
The USB 3-2-1 Raven 3124 complies with USB 2.0 and USB 3.1 Gen 1 specications governing the design of
USB devices. However, there is no guarantee that all USB devices or hosts will be compatible as there are a
number of dierent characteristics that may impact the operation of USB devices over extended distances.
Optional Ethernet Pass Through Connection
The Raven 3124 oers a 100 Mbps Ethernet pass through connection that can be used for a variety of
purposes including:
• Connecting network devices
• Providing remote network access to the same location as the REX unit
• Leveraging existing cabling to provide USB 3-2-1 connectivity without losing network connectivity

Optional USB Extender Mounting Options
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 Order Part #10-00620 USB Mounting Kit - Silver)
2. USB Extender Direct Surface Mounting (Using your own hardware, stencil provided on page 10)
OPTION 1: USB Extender Mounting Kit - each kit includes:
• 2 mounting brackets
• 4 (M3) locking washers
• 4 (M3 x 10mm) Phillips screws
• Mounting bracket installation guide (see diagram below)
1 kit required to mount per LEX or REX
Using a Phillips screwdriver, in the order as illustrated below, fasten and secure the provided screws, locking
washers and brackets into place.
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)
mounting hole
The bottom of the enclosure features four pre-drilled holes for optional surface mounting.
Distance between the enclosure mounting holes:
42.0mm x 205.5mm
1. Mark the center point of each of the four holes on your mounting surface either by directly measuring or
printing a stencil from www.icron.com/pdf/R-M-stencil.pdf .
2. Hardware recommendation: M3 locking washers and M3 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 3.97mm (5/32”) 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.
note
Do not exceed a screw depth of 10mm (0.4”) into the unit or damage may occur.
