Duplex multimode ber cabling is required for the Raven 3124 for extending up to 200m using 50/125m OM3 grade cable. The cabling subsystem must provide a duplex connection with crossover, and must be terminated with Duplex LC connectors at both ends. Host USB Cable OM3 Fiber Optic Link Cable USB Devices USB 3-2-1 up to 200m over MMF LEX LAN REX IP Control 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 speci ed distance. 6 Installing the LEX Unit 1. Place the LEX unit near the computer. 2. Assemble the power adapter and country speci c 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 con rm 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. note To open Device Manager in Windows XP: Right click "My Computer" then select: Properties >> Hardware tab >> Device Manager note To open Device Manager in Windows 7: Open the Start Menu, right click on "Computer" then select: Manage >> Device Manager note To open Device Manager in Windows 8, 8.1 or 10: Right click the Start Menu and then select: Device Manager 7 3. For macOS users, open the System Profiler to con rm 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. note To open System Profiler in macOS: Open the Finder, select Applications, then open the Utilities folder and double click on the System Pro ler 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 speci cations 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 di erent characteristics that may impact the operation of USB devices over extended distances. Optional Ethernet Pass Through Connection The Raven 3124 o ers 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 Up to 200m LAN over OM3 MMF Network Device Up to 100m LEX CAT 5e/6/7 REX Up to 100m CAT 5e/6/7 Connect any network device or access port into the RJ45 socket label "LAN" using up to 100 meters of standard CAT 5e, 6 or 7 cabling. 8 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. 9 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: 42.0mm x 205.5mm mounting hole 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.
