The USB Director/4-Port Hub is a dual-powered device that can be powered via the uplink connection (bus-powered) or via an optional power supply (self- powered). When bus-powered, the four downstream ports support “low-power” devices rated at less than
1⁄2 watt (1⁄10 amp @ 5 VDC) each, such as a camera, printer, scanner, or another hub. “Low-power” devices can also plug into these ports. The power switchover is automatic when the optional power supply is plugged into the hub.
Each downstream port supports either full-speed (12 Mbps) and/or low-speed (1.5 Mbps) signaling automatically.
The hub and each downstream port are overcurrent and short-circuit protected.
2.2 System Requirements
To use the hub, you’ll need:
•A PC or Macintosh computer that supports the Universal Serial Bus (USB).
•Operating system with a generic USB hub driver.
