Rugged Industrial Grade 4-Port SuperSpeed USB 3.1 Hub
The USB3-104-HUB is a high performance, industrial grade, mountable solution for USB expansion. It is a high-speed USB 3.1 device, USB 2.0 and 1.1 compatible. Each of the four downstream ports are capable of SuperSpeed (5Gbps), Hi-Speed (480Mbps), Full-Speed (12Mbps), and Low-Speed (1.5Mbps) data transfers.
This product utilizes a high-performance, low-power USB 3.1 hub controller. It is USB-IF certified, Windows Hardware Quality Lab (WHQL) compliant, and its extended operating temperature is rated for industrial and military grade applications.
The USB3-104-HUB was designed to withstand a variety of environmental conditions such as shock, vibration, and temperature. This hub has latching / locking port connectors on both downstream and upstream ports to prevent accidental disconnects. The small, low profile, steel enclosure allows the device to be installed in numerous locations where multiple USB devices must share a single USB port. The rugged steel enclosure, positive retention connections, and extended temperature (-40°C to +85°C) operation makes the USB3-104-HUB stand out compared to commercially available USB 3.1 hubs.
Each card has light emitting diodes (LEDs) for status indications. A green LED near the upstream USB type B connector indicates power to the board. Each downstream port indicator lights Green, Blue, or Red, to indicate USB2/HighSpeed, USB3/SuperSpeed, or fault, respectively.
The USB3-104-HUB is fully protected from faulty peripherals connected to its downstream ports. Each port utilizes its own power distribution switch that provides overcurrent and short-circuit protection. If a fault occurs, the power distribution switch will disengage the respective port and illuminate its red fault LED. A fault occurring on one downstream port will not affect other devices attached to the USB-104-HUB’s other downstream ports. The disabled port can be re-enabled by clearing the fault and cycling power to the hub.
The USB3-104-HUB supports bus-powered and self-powered applications. Bus-powered mode is a limiting factor as downstream ports take power from the upstream port’s remaining available power. If downstream peripherals require more current, the USB3-104-HUB can be configured in self-powered mode. External +5V can be supplied to the card, which will provide 900mA (1200mA max.) to each downstream port. Power can be brought in via the DC locking jack / plug, or the 2-position screw terminal.
The USB3-104-HUB is designed to be used in rugged industrial environments but is small enough to fit nicely onto any desk or testing station. The board itself is PC/104 sized (3.550 x 3.775 inches, 90mm x 96mm) and ships inside a steel powder-coated enclosure with an anti-skid bottom. Mounting provisions available include a DIN rail and various panel mounting plates.
The OEM (board only) version is perfect for a variety of embedded applications. What makes the OEM option unique is that the PCB size and pre-drilled mounting holes match the PC/104 form factor (without the bus connections). This ensures easy installation using standard standoffs inside most enclosures or systems. The board can be added to any PC/104-based stack by connecting it to a USB port usually included on-board with embedded CPU form factors. The USB3-104-HUB OEM board can also be installed using standoffs inside other enclosures or systems.
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.
