Edgeport/21, Edgeport/421
The 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.
Plugging Edgeport Into Your PC
The Edgeport/421 has two modes of operation. With the power supply installed, the hub
operates as a self-powered hub with all four USB ports activated. Without the power sup-
ply installed, the hub operates as a bus-powered hub with only the first two USB ports
activated. For more information about hubs, see “Understanding Hubs” in the Appendix.
NOTE : If you first install the Edgeport/421 without the power supply and then connect the
power supply, you must disconnect and reconnect the USB cable on Edgeport’s back
panel before it will operate as a self-powered hub and recognize the two remaining USB
ports.
For the Edgeport/421, connect one end of the power supply into the back of your Edge-
port/42 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.
The “USB Cabling Diagram” in the Appendix shows the two USB connectors and respec-
tive receptacles.
For a downstream connection, 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 an
Inside Out Networks Hubport. Plug the Type B end of the USB cable into the back of the
Edgeport.
For an upstream connection, plug the Type A end of the USB cable into one of the Edge-
port/421’s USB Type A slots and the Type B end of the USB cable into the upstream de-
vice (e.g. a Rapidport, Hubport or another Edgeport/421).
* Power to the Edgeport/421 may be supplied by a UL Listed Direct Plug-In Power Unit marked “Class
2” and 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 the following:
Installing the USB Hub
For Windows 95 Users
Please review “Using USB with Windows 95” in the Appendix. 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 “Installing Edgeport Drivers” on page 10.
