Rugged, Industrial Grade, 7-Port SuperSpeed USB 3.1 Hub with High-Retention USB Connectors and Extended Temperature Operation

The USB3-HUB-7 is an industrial-grade 7-port USB hub optimized for harsh and rugged environments. This hub has latching / locking connectors on upstream and downstream ports as well as power, preventing accidental disconnects – making it perfect for applications that require vibration proofing. By using a USB-IF and Windows Hardware Quality Lab (WHQL) certified hub controller, compatibility is assured. The rugged steel enclosure, positive retention connections, and -40˚C to +85˚C operation makes the USB3-HUB-7 stand out compared to commercially available hubs.

Each connection has been designed for rugged use without loose or intermittent cables disrupting your application. When externally powered, the screw terminal or threaded DC Jack and cable secure the power connection. Screwlocks on the enclosure around the Type B USB connector and jackscrews on the cable secure the upstream connection. Latching Type A ports provide high-retention (50N) downstream connections compatible with all industry-standard USB cables.

The hub supports SuperSpeed (SS), Hi-Speed (HS), Full-Speed, and Low-Speed on all ports. Each downstream port indicator lights Red, Green, or Blue (RGB) to indicate fault, USB2/High-Speed, or USB3/SuperSpeed, respectively. The hub also supports bus-powered and self-powered applications. If downstream peripherals require more current, the USB3-HUB-7 can be configured in self-powered mode: bring external +5V to the board so downstream power is drawn from the external supply.  The optional ACCES PWR-ACDC-5V5A will provide 900mA to each downstream port. Power can be brought in via the DC locking jack / plug or via a convenient 2-position removable screw terminal.

This product is fully protected from faulty peripherals. Each downstream port utilizes a power distribution switch providing overcurrent and short circuit protection. If a fault occurs, the power distribution switch will disable that port and illuminate the LED red. The disabled port can be re-enabled by clearing the fault and cycling power to the port.

The board is designed to be used in rugged industrial environments, but is small enough to fit nicely onto any desk or testing station. The module is sized at 3.250″ × 5.750″, while the enclosure is approximately 3.46″ × 6.26” × 1.0”.

High Retention USB Connectors

The ever-growing presence of USB in the industrial/military marketplace has driven the need for USB connections to be reliable, dependable, and unfailing. Gone are the days of loose USB connections. All type A and type B USB connections used on USB3-104-HUB product feature a high retention, locking design that complies with the class 1, Div II minimum withdrawal requirement. Over 11 pounds of force (50 Newtons), is required to separate the type A connectors. These connectors have a positive locking tab to quickly differentiate it from standard USB connectors. The Type B connection follows the USB3 Vision standard and features a screw lock USB cable to ensure secure connection to the USB3-104-HUB. Using the fastened USB connections on this hub increases reliability in your system and ensures against accidental disconnection.

Information about our Free Software packages:

ACCES is proud to provide a full suite of software support with every Data Acquisition product. We are committed to supporting the most popular operating systems and platforms for our customers. Currently we are actively supporting XP -> 10, both 32 & 64 bit, including “Server 2008,” “Embedded,” and “Compact” flavors for all plug-and-play products including PCI, PCI Express, USB, and more. Many products continue to ship with support for additional operating systems such as DOS, Windows 95, 98, Me, NT4, and 2000.


Among the software we deliver with our products are sample programs in a wide variety of programming languages. These samples are used to demonstrate the software interfaces to our products — and many can be used as-is in your production environments, or to test functionality of the devices out-of-the-box. We’re currently actively supporting sample programs in Microsoft Visual C#, Visual Basic, Delphi, and Visual C/C++, with many devices including samples in Borland C/C++ 3.1 for DOS. Additionally we provide National Instruments LabVIEW compatible DLLs and many demonstration VIs for our devices.


Drivers for various operating systems are also provided, including active support for Windows XP -> 10 — all in both 32-bit and 64-bit flavors, and including consumer, server, and embedded varieties — as well as the 2.6 and newer Linux kernels and recent OSX / macOS versions. Many products continue to ship with driver support for Windows 95, 98, Me, NT4, and Windows 2000, but support for these operating systems is considered deprecated.

Setup Programs and Utilites

Our Data Acquisition devices also include a graphical setup utility that walks you through the process of configuring any option jumpers or switches on the device, as well as explaining a little about the various connectors present.

Many devices also include utility programs – little tools to make your use of the device easier, such as EWriter, a program that allows you to read and write data in the user-accessible EEPROM locations on all our USB data acquisitition products; or WinRISC, a “Really Incredibly Simple Communications” terminal program that lets you get started instantly with serial devices.

“Register Level” Documentation

Besides all this software in all these languages and operating systems ACCES has a policy of open and transparent development: none of our lowest-level “register” interfaces are hidden from you — we document every register in every bus card, every command in every serial board, and every usb control transfer in every USB Data Acquisition board. These lowest-level interfaces allow you to develop for our products in ANY operating system or language, regardless of our actively supporting it or having a driver for it. We have customers actively developing in ADA, Android, Python, Java, MATLAB, Solaris, and more, just by referring to our complete low-level interface documentation! And we provide the full source code to all of our drivers, regardless of operating system, to give you an even bigger head start in your own development tasks.

No Fees or Royalties

All of this software is provided at no additional charge, and is licensed under any of a variety of flexible — and royalty free — options. Check out our software license explanation if you’d like more information.

Custom Software

ACCES also offers Custom Software Services for our products. Our prices are unbelievably low, often as inexpensive as free! If you need something tweaked to support your needs, or an entire enterprise application developed from scratch, it is definitely worth your time to inquire with us, first.
