Introduction to Hubs

Thank you for purchasing the Hubport, a self-powered Universal Serial Bus (USB) hub designed to provide a
convenient and effective means of bringing USB connectivity to your PC, server, or laptop. The Hubport also
delivers the potential of Digi International’s Edgeport USB to Serial (RS-232) expansion module.

Hubs, critical components in the USB architecture, are wiring concentrators that enable the attachment of multiple
devices, thus converting a single attachment point into multiple attachment points. USB architecture allows a
cascaded multiple hub configuration with certain power limitations (explained later in this section). See figure 1.

Each hub has an upstream port, connecting to the host, and multiple downstream ports, connecting to downstream
devices, possibly including other hubs. A hub can detect attachment and detachment of downstream devices and
enable and monitor the distribution of the power to downstream devices via their integral hardware and the operating
system.

Each USB device reports its power requirements to the operating system, which then enables and disables the device
as a function of its power requirements and the amount of available power. High powered devices typically need to
be connected to a self-powered hub, such as the Hubport, which obtains power from its external power supply and
provides up to 500 mA for each downstream port. Only low powered devices, such as a mouse, can be connected to
a bus-powered hub, which obtains power from its upstream host and provides up to 100 mA for each downstream
port.

Due to the limited available power for bus-powered hubs, cascading two bus-powered hubs is an illegal topology,
and devices connected to the second hub will not function. USB specifications limit the connection of a bus-powered
hub to a self-powered hub or host only. All Hubports, except the Hubport/4c in bus-powered mode, operate as self­powered hubs, and are not affected by this limitation.

According to the USB Specification, the maximum limit of hubs cascaded in series cannot exceed five. In other
words, you may have a maximum of five hubs between any device and the host. This does NOT mean that the
maximum number of hubs in a system is five. Indeed, up to seven hubs can be connected parallel at any given level.
You must tally both external and embedded hubs when counting downstream hubs.

Connecting Your Hubport

Type A Type B

Note that Windows NT 4.0 users must install the drivers before connecting a Hubport. To connect the cables
included with your Hubport:

1) Plug one end of the power supply* into the back of your Hubport and the other end into an AC outlet.

2a) To connect your Hubport to a PC, plug the Type A end of the USB cable into one of the PC’s USB Type A
slots and the Type B end of the USB cable into the back of the Hubport.

OR

2b) To connect a standard USB device to your Hubport, plug the Type A end of the USB cable into the Hubport
and the Type B end into the device.

† USB 2.0 High Speed is not supported by Windows 98.

* Power to this product may be supplied by a UL Listed Direct Plug-In Power Unit marked “Class 2” with a minimum rating listed in
the Specifications table above if used in the U.S. and Canada or a power supply with similar rating and approved by your local
safety code if it is used elsewhere.

1. Some units may be equipped with a pigtail connection. Follow the polarity markings on the cable.

2. For polarity on Hubports with a threaded locking connector, use center positive as follows:

3. For polarity on all other Hubports, use the following:

Installing Hubport Drivers

For Windows 98, 2000, and XP Users

After following the instructions described in “Connecting Your Hubport” in the previous section, installation will be
complete.

For Windows NT 4.0 Users

Because Microsoft does not support USB in NT4.0, Digi International supplies a set of USB drivers that will be
installed along with the necessary Hubport drivers. NOTE: You must install the drivers using an account that has
administrative privileges!

To install the USB stack and Hubport drivers:

1) Insert the “Edgeport Driver” CD Version 2.60 or above into your CD-ROM drive.

2) When the welcome dialog appears, click the Install Driver button.

Once the driver installation program has begun, follow the on screen instructions.

3a) If you are installing drivers for the first time: An Information dialog informs you that the installation was
successful. After clicking OK, the installation is complete.

3b) If you are replacing existing Edgeport drivers: Follow the on-screen instructions. Note that, before beginning
the installation of the drivers, all applications with open ports must be closed and all USB devices unplugged. If
you close all the applications and unplug all the USB devices, then you will not need to reboot for the new drivers
to take effect immediately. If any applications are left open or USB devices plugged in, you may choose to abort
the installation or to continue and be required to reboot before the upgrade can take effect.

Follow the instructions described in “Connecting Your Hubport” in the previous section. When finished with the
instructions, your new communication ports, numbered sequentially following the existing ports in your system, are
ready.

Note that because Windows NT 4.0 is not Plug-and-Play, you will not see a pop-up dialog box indicating that new
hardware has been found. You may verify correct installation with the USB Status Utility.

The USB Status Utility (Viewer) can be accessed by clicking the USB icon in your system tray or by clicking on
Start/Programs/Digi USB/USB Status Utility. This utility lists all the USB devices installed on your PC and
provides other relevant information for each device. You may also use this utility to create a log file.

Interpreting the Status Lights

For Hubport/4 and Hubport/7

The green System Status Light indicates that the USB ports are successfully set up and the Hubport is operating
normally. The green Port Status Lights (numbered 1-4 or 1-7) each indicate that the corresponding port is powered.

For /c Hubport Models

The green Power Light located next to the power connector indicates that the Hubport has power. The green Port
Status Lights (numbered 1-4 or 1-7) each indicate that the attached USB device is connected and enumerated.
