Edgeport USB-to-Serial Converters offer an out-of-the-box alternative to serial cards for easy plug-and-play COM
port expansion. Multiple serial, parallel and USB ports can be added to a PC, thin client or server in minutes —
without opening the chassis or reconfiguring and rebooting the system. Its feature-rich design, reliable performance
and unmatched operating system support (Windows NT 4.0, CE, XP, 2000, 2003 Server and more) make the
Edgeport ideal for mission-critical enterprise applications.

Edgeport/21,
Edgeport/42, Edgeport/421
The Edgeport/21, Edgeport/42, and Edgeport/421 are multi-connector converters for mobile and high-end
workstation users who need to attach multiple serial (RS-232) ports, a printer port, and USB peripherals to a single
USB upstream connector.
Cabling Edgeport
Type A Type B
The Edgeport/42 and Edgeport/421 operate as self-powered hubs, requiring a power supply to function. (For more
information about hubs, see “Understanding Hubs” on page 18.) Connect one end of the power supply into the back
of your Edgeport and the other end into an AC outlet.*
The Edgeport/21 derives its power from the host machine through the USB cable, and thus, does not require a power
supply.
To connect your Edgeport to a PC or Hub, plug the Type A end of the USB cable into the USB port located in the
back of your PC or into an available USB port on a standard hub or into a Digi Hubport. Plug the Type B end of the
USB cable into the back of the Edgeport.
To connect a USB device to your Edgeport, plug the Type A end of the USB cable into one of the Edgeport/421 or
Edgeport/42 USB Type A slots and the Type B end of the USB cable into the device.
* Power to the Edgeport/421 may be supplied by a UL Listed Direct Plug-In Power Unit or Information Technology Equipment
Rated Power Unit rated 5 V dc, at least 2.5 A 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. For polarity, see diagram to the right.

Installing the Hub Drivers
For Windows 95 Users
After plugging Edgeport into your PC, the Update Device Driver Wizard for installing the generic USB hub may
appear. If so, follow the recommended on screen instructions. Otherwise, Windows 95 will bring up the Update
Device Driver Wizard for installing the Edgeport drivers, in which case you may proceed to “Edgeport Driver
Installation” on page 8.
For Windows 98, CE, SE, Me, 2000 and XP Users
After following the instructions described in “Cabling Edgeport” on this page, hub installation will be complete and
you may continue with “Edgeport Driver Installation” on page 8.
For Windows NT Users
No separate process is required. Go to “Edgeport Driver Installation” on page 8.

Using the Printer Port
For Windows 95, 98, CE, SE, Me, 2000, XP and NT Users
The parallel port on your Edgeport/421 and Edgeport/21 supports only printers. To use your newly installed printer
port:
1. From the Start menu, choose “Settings” and then “Printers.”
2. Right click on the printer you wish to use on your new port and select “Properties.”
3. In the Details tab, click on the drop down list box under “Print to the following port” and choose
“USBLPT1”, then click “OK.”

Edgeport/412, Edgeport/416
The Edgeport/412 and Edgeport/416 utilize a standards-based USB bus for connectivity, unlike many serial card
products which require additional external proprietary hardware to support the same number of devices. This
Edgeport also supplies four USB ports, providing users with a built-in migration path as peripherals become USBready. The converters can be rack mounted and easily daisy-chained together. These Edgeport converters are
available in two models: one with DB25 connectors and one with DB9 connectors. The two models are functionally
equal, but differ in the type and placement of the connectors.
Cabling Edgeport
Type A Type B
Connect one end of the power supply into the back of your Edgeport and the other end into an AC outlet.*
To connect your Edgeport to a PC or Hub, plug the Type A end of the USB cable into the USB port located in the
back of your PC or into an available USB port on a standard hub or into a Digi Hubport. Plug the Type B end of the
USB cable into the back of the Edgeport/412 or 416.
To connect a USB device to your Edgeport, plug the Type A end of the USB cable into one of the Edgeport’s USB
Type A slots and the Type B end of the USB cable into the device (e.g. a Rapidport, Hubport, Edgeport/421, etc.).
* Power to the Edgeport-DB25 and Edgeport-DB9 may be supplied by a UL Listed Direct Plug-In Power Unit or Information
Technology Equipment Rated Power Unit rated 5 V dc, at least 2.9 A 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. For polarity, see diagram to the right.
