Product Overview
The NComputing U170 kit enables users to dramatically cut computing costs by sharing the
untapped power of existing computers. The U170 access device and NComputing vSpace
software work together to efficiently harness excess computing capacity and enable multiple
users to share a single computer. Each user gets the full performance and capability of a PC,
including multimedia and video. Best of all, IT staff and end users do not need special training
because the solution is easy to setup and is compatible with standard PC software.
Connect one user per kit or a total of 10 users per host PC
With the NComputing U170, each user has a monitor, keyboard, mouse and speakers (sold
separately), just like in a conventional computing environment. However, instead of connecting
directly to the PC, these peripherals connect to the U170 access device. These very small,
solid-state devices connect with USB cables and optional USB 2.0 hubs to the shared PC (host
PC). The distance between the access device and the shared computer can be a maximum of
20 meters (66 feet) in compliance with standard USB 2.0 specifications on cables and hubs.
The U170 can also be easily attached and secured to the back of a monitor using the built-in
VESA mounting points.
The NComputing vSpace desktop virtualization software (included) divides the PC’s resources
into independent virtual workspaces that give each user their own full PC experience. vSpace
simplifies configuration by automatically assigning the keyboard, mouse, audio and any USB
devices attached to each workstation. In addition, you can take advantage of the auto-login
feature to automatically log in a user, thereby making the U170 a great product for kiosks,
schools, kids and digital-signage applications.

Minimum System Requirements
Host PC
Refer to the “vSpace Operating System Support Matrix” in the NComputing Knowledge Base for the
latest information on supported operating system versions (note that unless specifically listed in
the OS support matrix document, a new OS service pack may not be supported by then-current
vSpace software). For more information regarding Microsoft licensing, please see the Important
Notices section at the beginning of this document.
Almost any modern PC can be used to host NComputing vSpace software. The guidelines
below are a good rule of thumb for determining how many users you can provision on a host PC
and expect to have a native experience running general productivity software applications.

The table below describes the maximum bandwidth of the USB bus for modern PC
motherboards. Some PCs may contain multiple Enhanced Host Controller Interface (EHCI)
controllers that can double or triple the available bandwidth. These systems will have better
video performance when running more than four U170 devices on a host PC. To take
advantage of multiple controllers, connect any downstream hubs back to the host PC directly
rather than connecting all U170s downstream of one USB connection. Installing an additional
USB controller card in the host PC is also an option for large deployments.
1
These are general guidelines. Always test your applications first before deploying.
2
When installed on Windows XP, only five U170 devices can be supported. See
www.ncomputing.com/mslicensing for specific use cases.
3
Deployments with more than four users require dual Enhanced USB controllers.
4
For 64-bit operating systems, 6+ GB of memory recommended.
Note: The U170 requires USB 2.0 controller(s) for operation. In addition, some
older PCs may have difficulty booting with U170 devices (or other high-speed
USB audio devices) attached. In these cases, you may need to boot the host
PC first, and then attach the USB cable. This problem can sometimes be
resolved by installing a separate USB 2.0 PCI card into the host PC.

Installing the Hardware
This section shows how to connect a U170 device to peripheral equipment and to a host
PC.
Connecting Peripheral Devices
Refer to the illustrations below for information on the ports used to connect the U170 to
peripherals and to a host PC.
The U170 has two USB 2.0 connectors to support USB devices. These ports may be used to
connect to the following devices:
USB keyboard and mouse
Wireless keyboard adapter and an accessory port
A separate USB hub to support additional USB accessories
Note: USB devices (for example, flash memory drives) connected
downstream of a U170 will be assigned to the session logged in to that U170.
device.

USB Virtual Desktop (Model U170) User Manual
Page 10
Connection Options
The U170 may be attached to a host PC through any USB 2.0-compliant connection method.
This includes the use of USB 2.0 hubs, USB 2.0 extension cables and USB 2.0 active
extenders. Each segment of a USB connection, from device to host PC, device to hub, or hub to
hub, must be no longer than 5 meters. The USB 2.0 specification states that a total of four hubs
may be used downstream of the host PC before the U170 device itself. Because the U170 is
dependent on USB bus power, you should always use a powered hub directly upstream of a
U170 when a U170 is not directly attached to a host PC. See the illustrations below for
reference.
Note: The U170 device is powered by the USB bus and a single USB port can
provide power for only one U170 device with a mouse and keyboard. Adding
additional USB devices immediately downstream of the U170 that draw too
much power is likely to cause errors. Using a powered USB hub downstream
from a U170 for high power peripherals is recommended.

USB Virtual Desktop (Model U170) User Manual
Page 11
Mounting and Security
Using two screws (provided) you can attach the U170 to the back of an LCD monitor that has
VESA-compliant mounting holes, as shown below. To secure the U170 device, you can attach a
security cable using the provided slot (between the mounting screw holes).
Note: Performance may be impacted by poor quality cables or hubs. We
recommend using USB 2.0-certified cables with minimum wires sizes of AWG
24 (power) and 28 AWG (signal). (Note: the higher the number, the smaller the
wire.)

To uninstall the vSpace software, select Start>All Programs>NComputing vSpace>Uninstall.
Follow the prompts and the vSpace software will be removed from the host PC. You will be
prompted to restart the host PC to complete the process.
Client Access License (CAL) Installation
For multi-user applications, in addition to installing and activating the Windows Server operating
system license on the host PC, you need to acquire two types of client access licenses.
First, you need a standard Windows Server CAL for each user or device.
You also need to install a:
Remote Desktop Services CAL (RDS-CAL) when running on Windows Server
or
Windows MultiPoint Server CAL (WMS-CAL) when running on Windows MultiPoint
Server for each user or device accessing the system.
For Windows Server operating systems, you will need to add the Remote Desktop Licensing
Server role (provided with the operating system) to at least one host in your environment.
After you install the licensing server on a particular host:
You will use the Remote Desktop Licensing Manager application to activate the server
and add RDS CALs. Other hosts in your environment can then point to this license
server.
For Windows MultiPoint Server, the licensing server component is pre-installed and you
can simply use the MultiPoint Manager application to enter in your WMS CAL (instead of
using the Remote Desktop Licensing Manager, which does not accept WMS CALs).
For further details on setting up the license server and installing CALs, please refer to your
respective operating system documentation or refer to the article entitled: “How to Configure a
Remote Desktop Licensing Server for vSpace 6” in the NComputing Knowledge Base.
