Installation Guide

Installing the USB 3-2-1 Starling 3251C Extender System

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)

Preparing Your Site

Before installing the Starling 3251C extender, you will need to prepare your site:

1. Place the computer where desired and set it up.
2. Ensure to locate your USB device(s) within the cable-length of the computer. If not, adjust the location of your device(s) and/or computer accordingly.

CAUTION
Cable installation is important, particularly if high throughput applications are used. When installing, ensure the cable is installed away from, or isolated from potential sources of interference such as electrical wiring, fluorescent lighting, etc.

NOTE

• Use the included ARJ45 Cable Pulling Eye tool when installing included cable through conduits or other tight spaces.
• Use only the included cable with this product; do not cut or re-size the included cable.

Installing the LEX Unit

1. Place the LEX unit near the computer.
2. Optional: Apply 5V 3A AC power supply to unit. (Sold separately)
3. Connect the supplied USB 3.2 Gen 1 cable between the LEX host port and a USB 3 port on the host computer.
4. If the Power LED is AMBER, test the system with the connected device(s) to ensure system is stable. If not a 5V 3A power supply may be required.

Connecting the LEX to the REX

1. Plug one end of the included Cable into the Link port on the LEX.
2. Plug the other end of the included cable into the Link port on the REX.

Installing the REX Unit

1. Place the REX near and connect it to the USB device.

Checking the Installation

1. On the LEX and REX units, check that the Power and Link LEDs are on. If the Link LEDs are permanently off or blinking, then the cable between the LEX and REX units may not be installed properly or is defective.

2. For Windows users (7, 8, 8.1, 10), open Device Manager to confirm 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 only one instance of “Generic SuperSpeed USB Hub” listed.

   • 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 macOS users, open the System Profiler to confirm 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 one instance 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 Profiler 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 Starling 3251C complies with USB 1.1, USB 2.0 and USB 3.2 Gen 1 specifications 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 different characteristics that may impact the operation of USB devices over extended distances. USB Bus power operation is only guaranteed with USB-C Upstream facing port connections with a USB-C cable.

Optional USB Extender Mounting Options

The bottom of the Starling 3251C enclosure features four convenient pre- drilled holes for optional direct surface mounting and four mounting slots for easy cable-ties. Based on your requirements, choose from three available mounting options:

1. USB Extender Mounting Kit
2. USB Extender Direct Surface Mounting
3. USB Extender Cable-Tie Mounting

Option 1: USB Extender Mounting Kit
Order Part #21-00155 for Starling Starling USB Mounting Kit is available for purchase separtely, and only one kit is required per extender system.

Each kit includes:

• 4 mounting brackets
• 8 (M2.5×4.5mm) Phillips raised cheese head screws with lock and flat washers
• Mounting bracket installation guide (refer to diagram below)

Using a Phillips screwdriver, in the order as illustrated below, fasten and secure the provided screws into place.

INSTALLATION OF THE MOUNTING BRACKETS

OPTION 2: USB Extender Direct Surface Mounting (using your own hardware)

The bottom of the Starling 3251C enclosure features four pre-drilled holes for optional direct surface mounting. Using the stencil below, along with your own hardware you can directly mount your USB Extender on a surface.

Distance between the enclosure mounting holes: 42.00 x 33.70mm

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: M2.5 locking washers and M2.5 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 3.70mm (0.1457”) 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
To ensure the stencil below prints to scale be sure to set the page scaling setting to “none”.

Direct Surface Mounting Measurement Stencil

Option 3: Cable-Tie Mounting

The bottom of the Starling 3251C enclosure also features four convenient slots for cable mounting. Simply thread a cable
tie, (also called tie-wrap or zip tie), into the mounting slot and through the cable tie head and secure it to a pole or other surface by pulling it tight. Cable ties are not included with this system due to varying lengths dependent upon the application.

Technical Glossary

USB 3 and USB 2.0 Cables

USB cables have two distinct full-sized 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-C Cable
The Type-C Connector is used to connect to both USB Hosts and Devices.

ARJ45 Cables
Starling 3251C uses a custom cable assembly based on CAT 7 Cable and leverages an ARJ45 Connection. ARJ45 is a high speed (40Gbps) connection that provides superior cross talk performance when compared to a standard RJ45. The ARJ45 Receptacle is keyed and does not allow RJ45 connections.

CAUTION
ARJ45 Cables cannot be terminated in the field and must be done at the factory. Icron does not recommend or guarantee operation with any cable other than the one included with this product.
