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.
Two models are available: the IC165A includes a
110-VAC power supply and the IC165AE comes with
a 220-VAC power supply.
The Hub is compatible with the USB Version 1.0
specification and supports the power-saving Suspend,
Resume, and Remote wake-up operations.
NOTE
The USB specification does not allow for a bus-
powered hub to drive another bus-powered hub. That
is, two bus-powered hubs must be separated with a
self-powered hub.

11
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 (self-
powered). When bus-powered, the four downstream
ports support “low-power” devices rated at less than
1⁄2watt (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.

12
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.
• USB Director—4-Port Hub
• Hub Stand
• External power adapter
• 2-m USB cable (Type A connector
to Type B connector)
• This users’ guide

13
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).

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. The individual
port’s LED will turn on, indicating that power is applied
to its connector.
When the initial checkout is complete, USB low-power
devices can be attached to the hub. Refer to the
instructions supplied with each USB device for
their individual operation.
3.1.2 OPTIONAL SELF-POWERED CHECKOUT
Perform the initial bus-powered checkout described
in Section 3.1.1. Then connect the optional power adapter
into an AC outlet and plug the adapter’s DC power

16
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. To lay the hub flat, slide
the stand onto the back of the hub. To mount the hub
directly onto a wall, the side of or under a desk (any
vertical or horizontal surface), first secure the stand to
the desired location with two small screws (or any other
technique such as Velcro®strips) and slide the hub on
to the bracket.
3.3 Cable Connections
The standard USB cables are designed to ensure that
they plug into the correct receptacle. Each cable has
a connector that goes upstream toward the host end
(Type A) and a connector that goes toward the down-
stream device end (Type B). The maximum length of

17
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. Figure 3-1 shows
the cable connections.
Figure 3-1. Cable Connections.
NOTE
Low-speed connections can use unshielded or shielded
cable, but full-speed connections must use shielded
cable.

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. If the hub is self-powered, the device driver
can allow low-power and/or high-power devices to be
attached.
NOTE
Early device drivers may not enforce these power
limits. However, the USB Director/4-Port Hub is
designed to automatically protect the host connection
and the hub itself from overcurrent conditions if they
exist.
