L300/L230/L130 User Manual
Product Overview
The NComputing L-series access devices with vSpace™ desktop virtualization software dramatically cut your
computing costs by enabling up to 30 users to share a single PC, server or virtual machine. Each user gets
their own virtual desktop with a rich, multimedia computing experience that is practically indistinguishable from
running on a full PC. Best of all, IT staff and end users do not need special training because this end-to-end
solution is easy to manage and is compatible with standard desktop applications.
Product Comparison
This user manual covers three distinct L-series products: L130, L230 and L300. The entry-level L130
provides all of the basic features needed for a good virtual desktop experience, complete with keyboard,
mouse, monitor and speaker connections. The L230 adds a USB port for connecting storage devices, a
microphone port, and more color depth for an even better user experience. The L300 delivers the best
possible virtual desktop experience with the addition of a high-performance video acceleration system that
supports full screen motion video, higher screen resolutions and more USB peripheral ports. The following
table summarizes the key differences between the products in the L-series family.

System Requirements
The minimum recommended system specifications for a vSpace installation can be very minimal. The host PC
may only need 1-2 GB of memory, a 2.4 GHz single-core processor, and less than 100 MB of free hard drive
space to run a few users. However the number of users, intended application suite and overall performance
expectation will ultimately determine how powerful a computer must be in order to deliver the desired multi-
user experience.
Note: It is not advised to use a notebook PC as the host. Notebooks use power-saving features and technologies different
than a typical desktop PC. This may cause power management and memory incompatibilities.

support depends upon the host's configuration and performance expectations of the customer. Performance results are highly
dependent upon the individual host hardware, memory, video card, applications being used, OS and network conditions within
any LAN/WAN. Host requirements will vary, please test your multi-user environment before deployment. For more information
on supporting multiple simultaneous multimedia streams see the document "Configuring an L300 Multiuser Environment".

L300 Device Setup
The L300 must be connected to the host PC via an Ethernet switch, router, or other network connection. The
L300 has USB ports dedicated for mice and keyboards, as indicated by the mouse and keyboard symbols
below the horizontally oriented USB ports. The vertically oriented USB ports to the left of the audio
connections are for other USB devices.
NOTE: The USB keyboard and mouse ports ONLY support these types of devices. No other types of
USB devices are supported on these ports. The USB keyboard and USB mouse must be directly
connected to these ports and cannot go through a separate USB hub. Peripherals with integrated USB
hubs or combination keyboard/mouse devices are not supported by these ports. Other USB peripherals
can be connected to the vertically oriented ports that are to the left of the audio ports – note that these
generic ports are not active until you have connected to a vSpace session.
Network connection
The L300 device can be configured to use DHCP-assigned network settings, or use settings specified by the
user. To use DHCP-assigned settings, power on the device, then go into the Device Setup, click the

After a group has been created, the user may choose modify the group to add hosts, remove hosts, or alter the
Group Name. To accommodate flexible failover scenarios, a server is allowed to be a member of multiple
groups, and can be included in the same connection group multiple times.
Connection Group - Auto Rollover
NComputing L-series devices and vSpace software have been designed from the beginning to minimize
administrative management requirements, and the L300 builds on that legacy. The L300 has a new auto
rollover feature that can provide extended control for those customers needing those capabilities
When an L-series device is configured for “Autoconnect,” anytime the device is power cycled, and anytime a
user logs off the device, the device automatically attempts to connect to the vSpace server specified in the
autoconnect parameter.
The L300 adds the concept of a “server group” to the autoconnect feature which in turn creates the auto
rollover feature.
A “vSpace server group” is a collection of one or more individual vSpace servers specified by a name that’s
currently defined from inside each L300 devices setup interface.
If a server group contains only one name (or IP address), then the L300 attempts to connect to that server until
successful or until the L300 is reset. If the server group contains more than one name (or IP address), the
L300 tries to connect to the first server in the list for 5 seconds, and if no successful connection is made, the
28

L300/L230/L130 User Manual
L300 attempts to connect to the second server in the list (i.e., the device does an “auto rollover” to the next
server). If after 5 seconds, the L300 does not successfully connect to the second server in the list, the device
attempts to connect to the third device in the list, etc. When the L300 reaches the end of the list, it starts
again at the beginning of the “server group” and continues until a connection is made or until the L300 device
is reset. (To allow for unusual requirements or server weighting algorithms, an individual server name or IP
address may exist in multiple places in the list.)
Whenever an L300 disconnects from a session, autoconnect (if set) begins at the top of the connection cycle.
The device does not keep track of the last server to which it successfully connected. Issuing a device reset
command from the admin console will also cause the autoconnect processing to restart at the top of the cycle.
In the future as management features are added to the vSpace console, groups will be extended from a local
device implementation to allow administrators to create and use “server groups” that are global in scope and
management from the host vSpace console, until then groups must be managed on each device.
Device Setup - The “Login Settings” Tab
The Login Settings tab contains various device settings related to performance within Windows, including:
Video Settings

L300 Multimedia Acceleration
The L300 will display full screen streaming video across multiple user sessions and is optimized to do
so using NComputing’s vSpace transcoding process. This process works transparently to stream
video and support multimedia content in a terminal device well beyond what has been seen in thin
client or multiuser computing before. Full screen streaming video with matched sound synchronism
in the norm for vSpace and the L300.
vSpace Multimedia Transcoding and Numo
vSpace transcoding is designed to replicate the multimedia experience that the user would see on the
host. vSpace uses has two optimized video pipeline implementations to achieve the performance:
1. Direct JPEG
Streaming content that is capable on host is captured by our device driver, compressed
and passed over the wire to the Numo chip for decoding and scaling.
Direct JPEG has the capability to stream video content that the host is capable of
streaming. This makes Direct JPEG a seamless method of delivering vSpace
transcoding on the L300 without having configured the many video setting.
2. Directshow API
This method is similar to above but uses Microsoft’s API that allows for another level of
optimizations
Either method provides a great media streaming experience on the L300.

L300/L230/L130 User Manual
The Numo™ system-on-chip (SOC) in the L300 device and the vSpace-enabled host PC work closely
together to balance video streaming workloads. The vSpace software for the L300 features a unique
transcoding engine that can take most any media file format and transcode it for a low bandwidth
transfer over the network to the L300 client which then decodes and scales locally. This efficient
approach allows NComputing to offer low cost clients that can provide full-screen streaming video, up
to display sizes of 1920 x 1080.
The vSpace transcoding process works as follows. A streaming video file (.mp4, .wmv, etc.) is
activated from the L300 virtual desktop. The vSpace transcoding engine starts with the video that
has been decoded by the host computer and media player (and optimized with Directshow) and then
it encodes the data into a compressed video stream. This compressed video data is then sent over
NComputing’s UXP protocol to the L300 device. The Numo SOC in the L300 then decodes the data
locally and scales it to fit the screen and window resolution set in the user’s desktop. The diagram
below illustrates this process:

Encapsulation
A key advantage of the vSpace transcoding process is that the original video file’s codec processing
takes place on the host. This allows vSpace to work with a wide variety of codecs within the PC that
may be updated from time to time. These multiple video formats using multiple codecs are then
processed by the vSpace transcoding engine into a single compressed video stream that is decoded
in dedicated hardware on the L300. This enables the L300 to deliver an exceptional level of
performance at a low cost. The transcoding process for streaming video uses compression that
removes data that will generally not be detectable by the end user. However, the standard display
graphics for normal 2D applications are extended in a separate lossless process. This ensures the
best possible user experience for all types of interaction with the desktop.
Another key advantage of this approach is that full screen scaling on the L300 does not impact the
CPU utilization on the host since the Numo SOC’s scalar capabilities handle this function locally.
The L300 virtual desktop accelerates most video formats through standard media players, such as
Windows Media Player (which is included in all current Microsoft operating systems) or Media Player
Classic (which is included in the vSpace installation).
By default, these media players only playback a limited number of media types with just a few
preinstalled codecs (coder/decoder). Most host PCs do NOT come configured for a wide range of
support for media types, so additional supported codecs can be added when setting up the host and
configuring the NComputing vSpace installation. For an L300 to stream a given file the host must be
able to stream it first. The vSpace acceleration method on the host system directs the output of the
33

L300/L230/L130 User Manual
media playback to a compute-efficient transcoding engine that creates a low-bandwidth stream that is
transmitted to the L300 device over the network. The L300 then decompresses and scales the video
stream locally in hardware up to 1920x1080 resolution for optimal video quality and always with
flawless sound synchronization.
NComputing video acceleration for up to full-screen resolution directly supports Windows Media
Player 10 and 11 as well as Media Player Classic. Any other media player can be used for effective
display of videos in windows that are at approximately 480x360 resolution or less where acceleration
is not required. Some of these additional media players may also take advantage of the NComputing
video acceleration capabilities when configured to use the Directshow API and the appropriate
codecs -- check the online knowledge base or forum for community supported media player options.
The following table shows many of the popular media formats that are supported by the L300 video
acceleration feature using Windows Media Player 10 and 11 or Media Player Classic with appropriate
codecs installed. A reference of common industry codec’s can be found at

Optimizing for DirectShow
As mentioned Direct JPEG has the capability to stream video content that the host is capable of
streaming. This makes Direct JPEG a seamless method of delivering vSpace transcoding on the

L300 without having configured the many video setting. But Directshow does offer some added
performance benefits and using it will maximize the number of streams that can be obtained from a
single host, therefore we have provided what are mostly industry standard steps to configure
Directshow properly.
Microsoft's market leading Directshow API or by using NComputing Microsoft’s Directshow API is the
world’s most popular video playback API is therefore the most widely supported. Maximum
performance can be achieved with a standard install but to support a wider range of video file types
the administrator or user should:
Choose a video player that supports the Directshow API and configure it for Directshow
(Windows Media Player and Media Player Classic are installed by default)
Download the proper codecs for any video files they wish to play and enable them for
the player. Also setting the MIME type to the appropriate player will make sure the
association to the correct player is made
For playing .avi files, apply a filter to determine the true file encoder used.
Some video players that support Microsoft's API do not do so by default and configuration may be
needed. Proper setup of filters and codecs can assist in making this process simpler. The process
mentioned in the previous and next section will ensue that the maximum performance of the L300 can
be achieved across a wide range of video types.
Players that do not support Directshow or Direct JPEG should be avoided as streaming files that are
greater than ~480 x 360 will result in dropped frames, an overall reduction in video quality and greater
network bandwidth use.
Players, Codecs, and Filters
Windows Media Player is installed by default with any Microsoft OS and our vSpace installer now
includes Media Player Classic; therefore both players will be installed by default.
Download the proper codecs to support the video files types that are desired and enable them for the
player. A reference of common industry codec’s can be found at
Optimally a filter may be needed to determine the true file type of a .avi file. The instructions for one
such filter, Matroska, are described in the L300 User’s Guide. Also setting the mine type to the
appropriate player will make sure the association to the correct player is made.
As NComputing determines the optimal settings for players and/or Codec’s we will post them as
Knowledge Base articles.
Browser-based video acceleration
In addition to the media types supported above in stand-alone media players, the L300 also supports
acceleration of browser-based embedded video including Flash video. Unlike stand-alone media
players with discreet graphics output, the graphics output of browser-based video is combined with
the other web page content. vSpace software detects when embedded video is being played in a

browser and then directs the output of that video to the vSpace transcoding engine which creates a
low-bandwidth stream that is transmitted to the L300 device over the network. The L300 then
decompresses and scales the video stream in hardware up to full screen resolutions for optimal video
quality.
Users will find that video on popular websites such as YouTube™ will display full-motion content up
to 480p that can scale to full-screen at 1920x1080 resolution. During this process the display might
show a very brief blue window where the streaming content is going to play, this is part of vSpace
setting up for the transcoding process.
Browser-based animation optimization
Flash animations are optimized through vSpace and default rendering in the L300. The native
rendering of desktop application content by vSpace assures that users get fast updates, smooth
scrolling, and synchronized audio. The hardware-optimized performance of the L300 gives users a
great multimedia experience.
Using the vSpace Management Console
The vSpace Management Console is used to administrate client sessions and configure advanced features.
Several basic console commands can be accessed by administrators through the vSpace system tray icon.
These include:
vSpace Management Console – This opens the
Management Console so that advanced settings and
configurations can be made for the client sessions.
Station Information – Displays basic identifying data for
the current access device.
vSpace - Send Message – Opens the vSpace messaging window, which can be used to display
messages on any terminal connected to the same host.
Non-administrator users also have access to several settings through the vSpace system tray icon. These
include:
Station Information (see above)
vSpace - Send Message (see above)
Browser Acceleration – Enable or disable Browser Acceleration to
alter browser-based streaming-media performance (L300 access
devices only).
vSpace - Keyboard Settings – Configure the station’s keyboard default num-lock, caps-lock, and scroll-
lock states (access devices only).
To make advanced configurations, launch the vSpace Administration Console either from the (administrator session’s)
system tray icon or by the Start Menu shortcut labeled “vSpace Console”.

There is a feature in the vSpace software that keeps disconnected sessions running and available. If the user
reconnects while a disconnected session for that username is present, the software will connect the
disconnected session to the new session. The user will see the desktop as it was when the disconnection
occurred.
The administrator can configure the software to keep disconnected sessions running and available indefinitely
or to close them automatically after being disconnected for a specified period of time. The setting is in the
administrative console’s system settings and is called, “Clean up disconnected sessions not in use.”

Glossary
Access device: a network computing device using NComputing patented technology. It doesn't use
CPU, VGA, and PC chipsets; it only uses a programmable SoC to connect to a Host PC. An access
device using NComputing User eXtension Protocol (UXP) can be connected to Host PCs by using the
LAN cable. Also, it can be connected to remote PCs through the Internet using TCP/IP.
Administrator: a person who is responsible for managing a multi-user computing environment, such as
a local area network (LAN). The responsibilities of the system administrator typically include: installing
and configuring system hardware and software; establishing and managing user accounts; upgrading
software; and backup and recovery tasks.
Alias: a fictitious name used by an individual as an alternative to her or his true name.
Client/Server: describes the relationship between two computer programs in which one program, the
client, makes a service request from another program, the server, which fulfills the request.
Console: the text entry and display device for system administration messages, particularly those from
DHCP: (Dynamic Host Configuration Protocol) is a communications protocol that lets network
administrators centrally manage and automate the assignment of Internet Protocol (IP) addresses in an
organization's network. Without DHCP, the IP address must be entered manually at each computer in
an organization and a new IP address must be entered each time a computer moves to a new location
on the network.
Download: the transmission of a file from one computer system to another.
Ethernet: the most widely-installed local area network (LAN) technology - specified in a standard, IEEE
802.3.
Firewall: a set of related programs (located at a network gateway server) that protect the resources of a
private network from users on other networks and control what outside resources its own users have
access to. (The term also implies the security policy that is used with the programs.)
Gateway: a network point that acts as an entrance to another network. On the Internet, a node or
stopping point can be either a gateway node or a host (end-point) node.
Host Computer: a computer in which the vSpace program has been installed
Internet: a worldwide system of computer networks in which users at any one computer can, if they
have permission, get information from any other computer (and sometimes talk directly to users at other
computers).
IP Address: the Internet Protocol (IP) is basically the set of rules for one network communicating with
any other (or occasionally, for broadcast messages, all other networks). Each network must know its
own address on the Internet and that of any other networks with which it communicates. To be part of
the Internet, an organization needs an Internet network number, which it can request from the Network
Information Center (NIC). This unique network number is included in any packet sent out of the network
onto the Internet.
LAN: local area network (LAN) is a group of computers and associated devices that share a common
communications line or wireless link and typically share the resources of a single processor or server
within a small geographic area (for example, within an office building). Usually, the server has
applications and data storage that are shared in common by multiple computer users. A local area

network may serve as few as two or three users (for example, in a home network) or as many as
thousands of users (for example, in an FDDI network).
Log on: in general computer usage, logon is the procedure used to get access to an operating system
or application. Almost always, a logon requires that the user have (1) a user ID and (2) a password.
Often, the user ID must conform to a limited length such as eight characters and the password must
contain at least one digit and not match a natural language word
MAC Address: in a LAN or other network, the MAC (Media Access Control) address is your computer's
unique hardware number. (On an Ethernet LAN, it's the same as your Ethernet address.) When you're
connected to the Internet from your computer, a correspondence table relates your IP address to your
computer's physical (MAC) address on the LAN.
vSpace: NComputing Desktop Virtualization software
PC: Personal Computer
Router: in packet-switched networks such as the Internet, a router is a device or, in some cases,
software in a computer, that determines the next network point to which a packet should be forwarded
toward its destination. The router is connected to at least two networks and decides which way to send
each information packet based on its current understanding of the state of the networks it is connected
to.
User: one who uses a computer system. Users may need to identify themselves for the purposes of
accounting, security, logging and resource management. In order to identify oneself, a user has an
account and a username.
USB: (Universal Serial Bus) is a standard designed to allow peripherals to be connected to a computer
using a standardized interface socket and to improve plug-and-play capabilities by allowing devices to

FAQ
For the latest information and FAQ, please visit the NComputing online
knowledge base at:
Q: Must the versions of the vSpace software in a network be the same?
A: Yes, different versions can cause data communication problems. Please keep all vSpace software updated
with the latest version.
Q: When I start my access device, why is the server connection list blank? I have the vSpace software on a
host PC in my network. I can connect to the host PC if I provision its IP address in the access device.
A: This condition occurs when the host and access devices are on independent subnets. The access device
can run in this mode, but will never see the host PC in its server connection list.
Q: When I go to the device list in the administration console, why do some of my access devices never show
up in the list?
A: This condition occurs when the host and access devices are on independent subnets. The access device
can run in this mode, but its record will never appear in the administration console’s device list.
Q: When I try to do a manual firmware update on the access device, why does it not connect to the host PC
and download the firmware?
A: This condition occurs when the host and access devices are on independent subnets. An access device can
run in this mode, but it can only download firmware updates when it is on the same subnet as the host PC.
Q: When I start my access device, why does it not automatically update its firmware from the host PC like my
other access devices do?
A: This condition occurs when the host and access devices are on independent subnets. The access device
can run in this mode, but it can only download firmware updates when it is on the same subnet as the host PC.
Q: I can't download any vSpace software updates.
A: Make sure that the software is registered and the correct TCP/IP ports are open (see “Product Registration”
section).
Q: Why does a warning message appear when I install the vSpace software?
A: Windows provides a firewall that displays a security warning message when a new network port is used
(see below). If you click the “Keep Blocking” button, you will not be able to find NComputing servers. If you
select the “Unlock” button, the port will be open unless you block it manually. If you select the “Ask Me Later”
button, the port will be open temporarily and the security message will continue to appear whenever the port is
accessed.

L300/L230/L130 User Manual
Q: Can the product support 10Mbps or 1Gbps?
A: No, only 100Mbps is supported.
Q: What is transcoding?
A: Transcoding is the process of converting media formats from one type to another. This is a common
technique used when wanting to optimize video for a given player or device. For instance, you may transcode
some video to play on a mobile phone. vSpace has an efficient transcoding engine that converts video into a
stream that can be locally decoded and displayed on the L300 device in real time, completely transparent to
the end user.
Q: If a customer wants to publish video content optimized for the L300, what format is best?
A: Original content up to standard DVD resolution (D1 - 720x480) will have the best playback experience.
Content may be encoded in many codecs, but if being distributed over the web, high compression H.264 or
MPEG4 delivers small file sizes, but if size is not an issue, lower compression formats such as MPEG2 require
less processing on the server. Please create a test clip in one of the supported formats mentioned in the
Multimedia section and test it on your intended video player.
Q: The accelerated multimedia feature of the L300 sounds like simple multimedia redirection. How is this
different?
A:
Multimedia redirection found in terminal server products from Microsoft or Citrix simply send the entire
media file over the network to be played by the client. This means that the client must have a full media player
software stack and the necessary codecs to decode those files. This means that to achieve the same quality of
video as the L300, a thin client must be 2-3X more expensive and require painful management of the local
software stack to constantly ensure that codecs are loaded. Typically, this means the device needs to be
similar to a full PC.
