What is the access terminal?
The L-series access terminals enable you to dramatically cut computing costs by sharing the untapped power of
PCs. The access terminals, Ethernet-based extension protocol, and terminal services software work together to
efficiently harness excess computing capacity and enable multiple users to share a single 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 PC applications.
What is the terminal services software?
Note: This document uses the following terms interchangeably: "User software," "host PC software," "terminal
services software," and "NCT-2000-XP".
NCT-2000-XP, the terminal services software, divides the host PC's resources into independent sessions that
give each user their own robust PC experience. One PC can support up to ten users when running on a desktop
operating system, such as Microsoft Windows XP. With a server operating system on the host (Microsoft
Windows 2003 Server or Linux), up to 30 users can be supported simultaneously. NComputing terminal service
software also works with the optional NControl and NShield software that add more centralized management
capabilities such as remote monitoring and host PC data backup.
Features
The L-series access terminals do not have a CPU, hard drive or CD-ROM, yet most users find it
indistinguishable from a full PC environment. The L-series exclusive technology allows you to add up to 30
computing terminals to your existing PC. Each access terminal offers a full and independent computing
experience.
Simultaneous desktop operation
Each access terminal accesses the host PC OS and can run its applications concurrently and independently
through Ethernet.
Minimal Maintenance Required
You only have to maintain and upgrade the host PC since the access terminals have no CPU, hard drive, or CD-
ROM.
Small sleek design
Allows more room in your office or on your desk, and can even mount on the back of your LCD with included
bracket.
Eco-friendly
Since the access terminals have no moving parts, it makes no noise and saves energy by drawing only 5 watts.
Supports multiple resolutions
640x480, 800x600, 1024x768 and 1280x1024, by 16-bit colors.
Additionally, the L130 supports 1440x900 by 16-bit colors and the L230 supports 1440x900 by 24-bit
colors.
New Feature: Microphone
The L230 now includes a microphone port.
Minimum System Requirements
A host PC with at least:
•A 2 GHz processor

7
•512 MB RAM
•60 GB hard disk drive
•Ethernet switch or router
Do not use a notebook PC as the host. Notebooks use power-saving features and different technologies than a
typical desktop PC, and this causes power management and memory problems.
Conceptual Diagram
Installation
Install the terminal services software (optional, but must be done once)
Insert the Software Installation CD into the host PC's CD drive.
In most cases, a window will automatically appear after a few seconds with installation options. If it doesn't
appear after 2 minutes, go to "My Computer", open the CD drive's icon, and start the "Setup" application.
At the installation screen, click on the "Install Program" button.
Before the installation starts, the installation software attempts to connect to the Internet to compare the software
version on the CD with the latest software version on the NComputing server. If there is a later version on the
NComputing server, a prompt will appear to ask if you want to use the version on the CD or if you want to
install the latest version. It is recommended to install the latest version rather than use an older version on the
CD.

8
Note: The following message will appear if any computer on the network is not connected to the Internet or a
program such as a firewall blocks the port.
The following ports should be opened on the LAN: TCP Ports 27605, 3581, 3597, 3645, 3646, 3725; UDP Ports
1027, 1283 (these are subject to change).
At the "Welcome" screen, click on the "Next" button.
At the antivirus and firewall warning screen, click on the "Next" button.
At the software license screen, you may view the software license and print it out. When you are finished, click
on the "I agree" checkbox, then click on the "Next" button.

9
At the software terms of use screen, you may view the software terms of use document and print it out. When
you are finished, click on the "I agree" checkbox, then click on the "Next" button.
At the readme file screen, you may view the readme file and print it out. When you are finished, click on the
"Next" button.
At the "Choose destination location" screen, you can install to the default location, or you can choose a different
location. When you are finished, click on the "Next" button.
At the "Choose Password for Administrator" screen, select whether or not to use an administrator password and
whether or not to install the Network Administration Console. If you choose to use an administrator password,
enter it and retype it. Click on the "Next" button.

10
Note: The Network Administration Console allows you to administer the terminal service software and the
access terminals in your network. It is recommended to be installed at least once on each network to enable
administration tasks. It may be installed on every terminal service software installation.
At the installation confirmation screen, review the selections and click on the "Next" button.
The software is installed.
At the "Add new users" screen, select whether or not you would like to add new users to the system. If you click
on the "Yes" button, the installation program will launch a screen to administer user accounts on the host PC. If
you click the "No" button, the installation process will continue without bringing up the user administration
screen.
Note: It is recommended that all users have their own user accounts to enable control of their own settings.

11
At the "NCT-2000-XP successfully installed" screen, select whether or not to restart the computer.
Note: It is required to reboot the computer before using the terminal service software or the access terminals
connected to the host PC
Connect the Access Terminal
The access terminal must be connected via Ethernet to the host PC. This can be done using an Ethernet switch, a
router, or some other network connection method.
When registering the software, all the access terminals must be connected to the host PC using Ethernet
Network connection
Note: If the network is configured to use DHCP to get dynamic IP addresses, you can setup the access terminal
to use it.
Go to the access terminal and select the "Options" button, then select the “Setup” button.

12
In the "Network" tab, select whether to use a dynamic IP address or a static IP address.
If you setup the access terminal to use a dynamic IP address, you don't need to enter anything as the IP address.
Click on the "Save" button.
If you setup the access terminal to use a static IP address, you must enter the IP address and the default gateway.
Click on the "Save" button.

Installation with monitor mount (L130 and L230 only)
The L130 and L230 products include a monitor mount, mounting collar, monitor mount screws (silver color) and
mounting collar screws (black color) for mounting it to the back of a monitor. To mount the terminal, first secure
the monitor mount to the back of the monitor, as in the following pictures.
The above picture shows the monitor mount attached to the back of the monitor with the four silver screws. Note
that the black attachment clips are oriented vertically. Also, note there are holes in the monitor mount that
support a 100 mm mount and a 75 mm mount.

14
The above picture shows the terminal attached to the monitor mount. This is done by sliding the terminal on the
attachment clips and pushing it down to secure it.
The above picture shows the mounting collar holding the terminal in place with the four black screws.
The above picture shows the L130 on the mounting bracket, secured with the mounting collar, and all cables
connected.
The above picture shows the L230.
