USB DIRECTOR/4-PORT HUB 2. Introduction 2.1 Overview The USB Director/4-Port Hub is a medium-speed and standalone universal serial bus (USB) hub. The USB Director/4-Port Hub supplies four additional USB ports to attach devices and/or additional hubs. The hubs can easily be daisychained, up to five hubs deep in series, in any combination that does not exceed 127 devices, including the hubs. No additional software is required to support the Hub.
CHAPTER 2: Introduction 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 (selfpowered). 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.
USB DIRECTOR/4-PORT HUB (A generic hub driver is supplied with the latest version of Microsoft Windows 95 also known as OSR2.1 or later, Windows 98, Windows NT, or Windows 2000. Call Technical Support at 724-746-5500 if you’re using Windows 2000. 2.3 What the Package Includes Your package should include the following items. If anything is missing or damaged, please call Black Box at 724-746-5500.
CHAPTER 2: Introduction 2.4 Hardware Description The USB Director/4-Port Hub has one connector for upstream connection to a host, and four port connectors for downstream connections to the devices. It also has a power connector for the optional power supply, eight LED indicators for status information, and a stand for mounting (see Figure 2-1). ® BLACK BOX R 724-746-5500 4 Power Bus / Local 3 Reset 2 Port 4 Port 3 1 Port 2 Port 1 Uplink USB Director Uplink 5.25V 2.1A Figure 2-1.

CHAPTER 3: Installation 3. Installation 3.1 Initial Checkout 3.1.1 BUS-POWERED CHECKOUT While the host PC is powered on, connect a USB cable between the host’s USB type A receptacle and the Hub’s type B receptacle (uplink connection). The Hub’s power indicator, bus-powered, and the uplink port LED will turn on. Then the host PC will locate and run the generic hub driver supplied with its operating system. The hub driver will identify the USB Director—4-Port Hub and enable each of its four ports.
USB DIRECTOR/4-PORT HUB cable into the Hub’s power connector. The hub will go through a reset and operate in the bus-powered mode; however, the bus-powered LED will be off. When the optional power adapter is connected, USB high-power devices can be attached to the Hub. Refer to the instructions supplied with each USB device for their individual operation. 3.2 Hub Mounting To stand the hub upright on a desk or shelf, slide the stand onto the base of the hub.
CHAPTER 3: Installation the cable is 16.4 ft. (5 m) for full-speed connections and 9.8 ft. (3 m) for low-speed connections.

CHAPTER 3: Installation 3.4 Power Controls When the hub is connected to the USB connection, it initially draws less than 1⁄10 of an amp from the host connection. Each port is enabled one at a time. Initially, all attached devices are only allowed to draw 1⁄10 amp or less each. When the hub is identified, it tells the host whether it is bus-powered or self-powered. If the hub is bus-powered, the device driver should only allow low-power devices to be enabled.
USB DIRECTOR/4-PORT HUB 4. Operation The USB Director/4-Port Hub is an extension of the host’s USB bus. You only have to plug it into the host USB connector to operate. The hub is hot-pluggable; you can plug it in at any time, even when the host PC is powered on. When attached, the operation is automatic. The host software will detect that a device has been attached to the USB bus, query the device to identify it, and load the appropriate driver.
CHAPTER 4: Operation a resume command from the host that takes the device out of suspend. The Hub is supported by the Microsoft® Windows® generic USB hub driver supplied with the latest version of Microsoft Windows 95 also known as OSR2.1, Windows 98, and Microsoft Windows NT 5.0. NOTE If you’re using WIndows 2000, call Technical Support at 724-746-5500.
USB DIRECTOR/4-PORT HUB Table 4-1. LED Functions LED Position Function POWER ON (green) OFF Power ON. No power or low input voltage (< 3.5 VDC). BUS/LOCAL ON (green) OFF Bus-powered. Local power (self-powered). RESET ON (amber) Reset or uplink disconnected or host powered off. Not reset/Host connection established. OFF PORTS 1–4 ON (green) Individual port power. Enabled by the host and +5 VDC applied.
CHAPTER 4: Operation Table 4-1 (continued). LED Functions LED Position Function UPLINK (continued) Red LED ON (red) A bus-powered overcurrent condition exists. OFF Port disconnected or low input voltage. NOTE All LEDs are normally turned off when suspend mode is activated. Exceptions to this are when error conditions exist before entering suspend mode.
USB DIRECTOR/4-PORT HUB 5. Troubleshooting 5.1 Power Problems If an overcurrent condition of > 1⁄2 amp is sensed at a port by the hub, that port’s power will be limited (< 1⁄10 amp). The condition will be reported back to the host, the host will shut off the port, and the port LED will be off. If a port LED is off, an overcurrent condition may exist on that port and/or the port that has been turned off by the host.
CHAPTER 5: Troubleshooting on. If the uplink port red LED is on, disconnect all of the devices and reset the hub as described on the previous page. Then plug the devices in one at a time and run their applications, noting when the failure reoccurs. NOTE If a device is unplugged while in suspend mode, its configuration informaton will be reset. To reconfigure, simply reset the Hub. 5.2 Other Problems The following is a list of symptoms, possible causes, and suggested solutions.
USB DIRECTOR/4-PORT HUB Symptom: Hub host port red LED is on. Cause: Overcurrent condition exists. Solutions: 1. Disconnect port 1 through 4 devices one at a time until the LED goes off. 2. If all devices are removed and the LED is still on, reset the hub. To reset the hub, unplug its uplink connection and plug it back in. If the LED is still on, the unit is defective and should be replaced. 3. If the LED is now off, reconnect the devices one at a time until the failure reoccurs.
CHAPTER 5: Troubleshooting Symptom: A single port LED is off. Cause: The port has been disabled by the host. An overcurrent condition may exist on that port or the device driver identified a problem with the device and turned it off. Solutions: 1. Disconnect the device. If the LED does not come on, reset the hub. To reset the hub, unplug its uplink connection and plug it back in. If the LED turns on, you can reattach the device. 2.
USB DIRECTOR/4-PORT HUB Symptom: All LEDs are off. Cause: The hub has been disconnected, powered off, or put into suspend mode. Solutions: 1. Host is in suspend mode. Press any key on the keyboard or move the mouse to exit suspend mode. 2. Upstream cable is disconnected. Reconnect. 3. Upstream hub or host is powered off. Make sure all upstream hubs are powered on. Symptom: Power LED is on and all port LEDs are off. Cause: The hub has not been enabled by the host. Solutions: 1. USB driver not loaded.
CHAPTER 5: Troubleshooting 2. Upstream cable is disconnected. Reconnect. 3. Make sure all upstream hubs are powered on. 5.3 Calling Black Box If you determine that your USB Director/4-Port Hub is malfunctioning, do not attempt to alter or repair the unit.
