The USB3-104-HUB is a high performance USB 3.1 Gen 1 high-speed industrial grade solution for USB expansion. The USB3-104-HUB supports data transfers up to 5Gbps and is backward compatible with the USB 3.0, 2.0 and 1.1 standards. Each of the four downstream ports is capable of SuperSpeed (5Gbps), high speed (480Mbps), full-speed (12Mbps), and low-speed (1.5Mbps) data transfers.
Industrial Design
The USB3-104-HUB utilizes a high-performance, low-power USB 3.1 hub controller with extended operating temperature ratings suitable for industrial and military grade applications. The USB3-104-HUB is housed in a low profile; steel enclosure designed to withstand high shock, vibration, and temperature. An anti-skid bottom provides stability for desktop applications. The enclosure can also be DIN rail mounted or mounted in a standard PC 3.5Ē front panel drive bay. An OEM (board only) PC/104 form factor version is available for embedded applications.
Data and Power Status
Light emitting diodes (LEDís) display power and port status. 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-HUBís other downstream ports.
A Variety of Power Options
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 available power. If downstream peripherals require more current 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 an optional 2-position screw terminal.
High Retention USB Connectors
The USB3-104-HUB utilizes Industrial-Grade High Retention type A and B USB connectors to ensure a reliable, dependable, and unfailing connection. For embedded OEM applications, additional miniature USB input headers are provided on the PCB.
