1 Introduction  
OCTOPUS is a software system which allows an operator sitting at his or her Windows NT workstation to  
control the mouse and keyboard of a networked Windows NT computer. This feature gives operators in a  
control room the ability to manipulate a shared wallboard display as though it is the display on the desk in  
from of him or her. Octopus has been designed to be easy to install, easy to use, and easy to integrate into  
a control room setting.  
This manual will cover the following topics:

2.1 The Software Octopus  
The OCTOPUS software system is separated into three distinct software modules, each of which has  
specific installation and operation requirements, these modules are:  
OCTOPUS CLIENT is software that is installed on the operators workstation. This software package is the  
user interface to the system, allowing operators to move between manipulating their local desktop and  
that of the remote wallboard.  
OCTOPUS SERVER is a software service/application that is installed on the wallboard display system. This  
software accepts network connections from both the OCTOPUS CLIENT and the OCTOPUS ADMINISTRATOR  
client. It communicates mouse movements and keyboard input received from the OCTOPUS CLIENT to the  
wallboard. The server also implements the prioritization requests sent to it via the OCTOPUS  
ADMINISTRATOR.  
OCTOPUS ADMINISTRATOR is optional software that implements prioritization of access to the wallboard.  
Windows NT is an inherently single user system, and thus if there are several operators which require  
access to the wallboard display, this can only be accomplished in a serial fashion. The OCTOPUS  
ADMINISTRATOR software permits an administrator to establish rules of access, allowing some users  
access to the wall, and others not. In addition to access rights, it also implements override priorities,  
where certain users can have privileged access to the wallboard. This software is typically installed on an  
administrators workstation, and should only be accessible to administrative personnel.

3.1 Octopus Software Installation  
Before installing Octopus 2.1 Service Release, please de-install all earlier versions  
of Octopus!  
Use the Add/Remove Software Option from the Windows Control Panel to uninstall  
Octopus!  
3.1.1 Hardware Prerequisites  
Pentium or Pentium II computer, 200MHz minimum recommended CPU  
CDROM reader  
32MB RAM minimum  
2MB free disk space per module  
Network card  
3.1.2 Software Prerequisites  
Windows NT 4.0 (SP3 or higher) or Windows  
TCP/IP support  
Administrator privileges  
Installation of the OCTOPUS software generally requires some decisions to take place prior to actual  
installation. Here is a synopsis of the decisions to be taken:  
3.1.2.1 Central Installation vs. Individual Installations  
The binary software for each of the OCTOPUS modules can be installed in a central location, on an  
application server (this can be the wallboard processor), or installed on each client machine as needed.  
We recommend installing the software in a central location to ease maintenance of the software as  
upgrades and patches are made available. This will require that all computers that are going to use the  
software have access to the directories that contain the installed software. In MS Windows operating  
systems, this means that the installation directories must be shared with each user having sufficient  
permission to read the directories.  
If you plan to install the software on each computer individually (e.g.: in a small control room), then these  
restrictions do not apply, although each machine must have it's own CDROM reader.  
3.1.2.2 Administered Use vs. Non-administered Use  
The OCTOPUS software can operate in essentially two modes, one where all users have identical access  
rights, and where each user has a defined priority level. When the software is installed, a default priority  
is granted to all users which if left as it is will permit first-come-first-serve access to the wallboard. If this  
is not a desired effect, then it is possible to assign each user, user and computer, or a global category a  
priority level, which will determine access rights to the wallboard. On order to facilitate this process, it is  
worthwhile to write down each of the users names, the machine names from which they will access the  
wallboard, and the roles each will play in the operation of the wallboard system. The issues surrounding  
this decision will be elaborated upon in a subsequent section of this manual.

3.1.2.3 Network Topology  
Although this manual is not meant to be general treatise on network setup, it should be noted that there  
are some rules of thumb which make setting up a control room with OCTOPUS software easier.  
Specifically, the more homogeneous the organization of the control room computer facilities, the better.  
Users, in general, should be in the same domain or workgroup. Duplicate user names across different  
domains or workgroups should be avoided. OCTOPUS privilege levels should parallel those of the  
network, i.e. users with greater network authority should most likely have greater access authority to the  
wallboard. User names should differ from group names and the name "All" should be avoided for both  
computer and users, as it is used as the global name  
3.1.2.4 Gathering information before installation  
The OCTOPUS software is protected by license key mechanism. In order to get a license key from Barco  
Control Rooms, one must provide certain information which identifies the computer. We require the  
MAC address of the computer's network card along with the name of your company. During installation,  
a dialog will be displayed containing all of this information, which can be printed, e-mailed or saved to  
file for later use. Be aware that depending on the configuration of your e-mail client, some of the  
information might be missing from the e-mail message body. In that case, go in the message body part  
and paste the data there using <SHIFT-INS> or <CTRL-V> (the information is already in the clipboard).  
This license key is only needed for the OCTOPUS SERVER. Send this information to Barco Control Rooms  
(support).  
Figure 2  
License information for Octopus Server  
Once you have gathered this information and sent it, the license key can be delivered to you via e-mail,  
fax, or over the telephone. Please see 6 Octopus server license, where all necessary addresses are listed.

3.1.3 General Installation Guidelines  
For the installation of the OCTOPUS software you'll need to log in as local administrator of your NT-PC.  
To start the installation, insert the OCTOPUS CDROM in your computer's CDROM drive (if you are  
sharing a CDROM over a network, insert the CDROM into the appropriate drive).  
Click on setup.exe in the Octopus folder on the CDROM or use the shortcut Start|Run and enter the  
appropriate drive and path and setup.exe. The following dialog pops up:  
Figure 3

Select Custom to install OCTOPUS CLIENT and OCTOPUS SERVER and/or OCTOPUS ADMINISTRATOR.  
Figure 5  
Custom installation of Octopus  
The installation of OCTOPUS software is follows the same steps for each of the modules (the OCTOPUS  
SERVER has license key information, the other modules don't), here are the steps you will be asked to  
perform during the installation:  
License Agreement. Please read it carefully.

User Information (only for OCTOPUS SERVER).  
Figure 7  
User Information entry dialog  
After accepting Barco's software license agreement, you will need to license the software by typing  
in a license key provided by Barco Control Rooms. The license key is only required for the  
OCTOPUS SERVER. If you do not type in a license key, an evaluation license key will be generated by  
the software. That key is good for 30 days, after which the OCTOPUS SERVER will not execute  
anymore.

If you don’t have a valid license key, an evaluation license key is generated which is  
valid for 30 days.  
If a new license key is required (either because of an invalid evaluation license key  
or because the network card has been replaced), Octopus has to be completely  
uninstalled and re-installed again with the new license key.  
Choose Installation Directory  
You can change the drive or directory where you are going to install the software. If you are  
satisfied with the default location (<windrive>:\Program Files\Barco\module name>), then you can  
ignore this.  
Figure 9  
Installation directory entry dialog  
Finish Installation  
If you're installing the OCTOPUS SERVER, you can install it either as a service or as an application.  
When installed as a service, the OCTOPUS SERVER will be started automatically before any users can  
logon and will have the same advantages and restrictions as any standard Windows NT service.  
To make use of the remote login it is mandatory to install OCTOPUS SERVER as  
service!  
The decision whether to install OCTOPUS SERVER as service or application is final and cannot be  
changed without a complete uninstallation and re-installation.  
When installing OCTOPUS SERVER as an application, it can be put in your startup.

During installation for every application shorcuts are generated. Use these shortcuts to start the  
required application.

3.1.4 Octopus Server Installation Considerations  
The OCTOPUS SERVER software is to be installed on the computer that will be controlled by operators in a  
control room. This is typically the wallboard display controller, although it can be any Windows NT 4.0 /  
Windows 2000 system (please see hardware/software requirements). You have the option of installing the  
OCTOPUS SERVER as a service. This will allow a user to login using a remote workstation running the  
OCTOPUS CLIENT. During the installation of a Barco wallboard display, this software will be installed by  
Barco personnel. Follow the general instructions above.  
3.1.5 Client Installation Considerations  
The client software can be installed two versions of Microsoft Windows: Windows 2000 and  
Windows NT.  
3.1.6 Administration Client Installation Considerations  
The Administration client application can be installed on Windows NT and Windows 2000 computers.  
Additionally the application should be installed on the computer from which a supervisor can have  
control over access to the wallboard, within visual range of the wallboard itself. If your control room does  
not require any level of prioritization of user access to the wallboard, then it is safe to not install this  
application.

4.1 Octopus Server  
The OCTOPUS SERVER is the central application in the OCTOPUS remote control software. This software,  
installed on a wallboard display server, will communicate with OCTOPUS CLIENT and Administrator  
applications. In its communications, it will translate messages sent to it from the client into mouse  
movements and keyboard events on the wallboard display server. All events that can be input into a local  
computer will be sent to the wallboard display. This effectively allows computer users sitting at his/her  
workstation to control a wallboard display, using the keyboard and mouse on the desk in front of him.  
4.1.1 Application startup  
The OCTOPUS SERVER application can be placed in the startup folder of the computer on which it is  
installed. Being in the startup folder makes the application execute automatically after somebody logs on  
to the machine.  
You can tell if the OCTOPUS SERVER application or service is running by looking at the system tray,  
where you will see the OCTOPUS icon. If the application has not been placed in the startup folder, then it  
is possible to select the application from the Start menu.

4.1.2 Application use  
There is no graphical interface available with the OCTOPUS SERVER, although you can click the right hand  
mouse button over the icon and select one of two menu items: Close and About Octopus Server (the  
Close item is not there for the OCTOPUS SERVER service).  
Selecting About will bring up a dialog window that lists general information about the application,  
including the version number, and contacts for support.  
Selecting the Close button quits the application.

4.2 Octopus Client  
The OCTOPUS CLIENT is the main user interface to the OCTOPUS system. The client interface enables a  
user to control a multiple wallboard displays with his/her own keyboard and mouse, via the network. In  
addition to this, the client has a number of features that make control of a remote display an intuitive and  
easy task.  
4.2.1 Application startup  
Much like the other applications in the OCTOPUS suite, the client application is generally started from the  
Windows Start menu.  
The application starts as a toolbar window on the top of the display. There will be a pixel size window  
over the top of the display, moving your mouse into this window will make the full toolbar appear.  
Moving the mouse out of the window will cause the window to shrink back to one pixel in size.

4.2.2 Application use  
The OCTOPUS CLIENT operates in essentially four modes: not connected, inactive, queued, and active. A  
non-connected client is not capable of controlling a remote wallboard display, as it is not in  
communication with any OCTOPUS server. An inactive client is in communication with at least one  
OCTOPUS server, although it is not actively sending mouse and keyboard information. A queued client is  
one where activation has been requested, but there is already an active client with a higher or equal  
priority using the display. In the queued case, a message is displayed in the message area of the main  
toolbar interface stating where in the wait queue the OCTOPUS CLIENT has been placed. An active client is  
redirecting all keyboard and mouse activity to a single connected OCTOPUS server, this has the effect of  
remotely controlling the wallboard display. An active client can have other non-active connections to  
other servers.  
Status of the application is reflected in the message area. Messages include:  
Status: Not connected  
Status: Connected to <hostname> - Inactive  
Status: Connected to <hostname> - Active  
Status: Connected to <hostname> - #1 in queue  
The OCTOPUS client, by default, starts as in an unconnected state. To control a wallboard display, it is  
necessary to connect the client to the OCTOPUS server that is running on the wallboard display computer.  
This is done via the Configure Connections dialog that can be displayed from the Options menu in the  
main interface.  
Figure 14

The Configure Connections dialog allows the user to specify the computer(s) on the network that is the  
wallboard display. In an environment where there are multiple computers to be accessed, it is possible to  
connect to multiple servers simultaneously.  
Figure 15  
Configure Connections dialog  
The Configure Connections dialog has several functional areas:  
Server information area: this lists all of the servers that can be accessed by the OCTOPUS client. Each of  
the computers is entered manually via the Add Server button and the Add server dialog. The server  
information area has five columns:  
Server: the name of the computer that is running the OCTOPUS SERVER application.  
Status: this indicates whether the client is in one of three states, with respect to the server: Not  
connected, connected, selected. When connected, it is possible for the user to control the wallboard  
display by activating the client. Its default state is Not connected. If the server is in selected state,  
then the activate button will pertain to that server. There can only be one selected server.  
Startup: this item indicates whether the client should automatically connect to the server the next  
time the client is executed. This automates the application startup process. Its default state is OFF.  
Reconnect: this item indicates whether the client should try to reconnect to the server if the  
connection is broken because of a network error. Its default state is OFF.  
Fallback: this item indicates which server the client is going to switch to in case the connection with  
the current selected server is broken by a network error. Only one server can be the fallback. By  
default there is no fallback server.  
Add Server and Del Server buttons: these buttons allow the addition or removal of OCTOPUS servers from  
the server information area.  
Server action buttons: these buttons are available only when the operation is permitted, otherwise they  
are grayed-out.

To connect to a server, it is first necessary to add that server to the server information area. Click the Add  
button to pop up Add server dialog that will allow you to add the server name to the list. No verification  
of the computer name, its connection to the network, and whether it is running the OCTOPUS SERVER is  
done at this point. The server name is placed in the information area with default values.  
Figure 16  
Adding server dialog  
Selecting the line in the server information area containing the server, you will be able to connect to it by  
pressing the Connect button. While the connection is being made, a dialog will inform you to wait.  
Figure 17  
wait for connection dialog  
If the computer is down, the server is not running on that computer, or there is some other network error,  
then it is possible for the dialog to remain up for up to 30 seconds. This error will be noted in an error  
dialog, and the computer will remain not connected: you will be required to remedy the error in order to  
continue.  
If the connection to the server is rejected, this is caused by having insufficient permissions. Either the  
administrator has installed an access rule that disallows your username or access from the computer.  
4.2.3 Activate  
Once the client is connected to at least one server, it is then possible to activate the client, and take control  
of a remote wallboard.  
There are several methods to activate the OCTOPUS client:  
Pressing the Activate button on the main toolbar interface. This will activate the Selected server.  
If the Server buttons option is checked, then there will be a button labeled with each of the  
connected server in the main toolbar interface. Pressing any of these buttons has the effect of  
activating that particular server.  
If the Administrator client is connected to the same server your OCTOPUS client is, it is then possible  
for the operator of the Administrator client to activate the client.  
4.2.4 Operation while active  
Once the client is active, the mouse image on the local display will no longer be visible. Any movement  
of the local mouse will be translated into movement on the OCTOPUS server computer display.  
Analogously, any keyboard input will become keyboard input on the remote display.  
4.2.5 Queued  
It is possible to be placed in a waiting queue when active, this condition occurs when a user already has  
access to the wallboard display and has a higher priority than you do.

4.2.6 De-activating the client  
To de-activate the client, and restore local control to the operator, it is necessary to perform one of the  
following actions:  
Use the Deactivate toggle key combination (default: CTRL-F5).  
Press the Return from server button if available on the wallboard display.  
The Administrator client can de-activate the client from the Administrator client interface.  
A user with a higher priority on the currently active server can de-activate your client by activating  
his/her client interface.  
4.2.7 Multiple server operation  
As it was mentioned earlier in the manual, it is possible to connect the OCTOPUS client to multiple servers  
simultaneously. It is possible to toggle, once in the active state, from one connected server to another via  
a pair of toggle keys combinations, Next server and Previous server. This allows the convenient and  
quick access to more than one wallboard display in a facility.  
In addition to this, if the Server buttons function is toggled on, then it is possible to select the server to  
activate from a list of buttons on the main toolbar interface. This is only available when the OCTOPUS  
client is in the inactive state.  
Also, if the client workstation and the server have multiple network adapters, it's possible to connect all of  
them at the same time; just use each adapter's IP address when connecting instead of the computer name.  
This setup allows one of the adapter to be a fallback if the main connection is broken because of a  
network failure.  
4.2.8 Octopus Client options  
The OCTOPUS client has several operational options available to the user to customize the behavior of the  
application.  
Mouse sensitivity is configurable from the Mouse sensitivity dialog.  
Figure 18  
Mouse Sensitivity dialog  
In the least sensitive position, each movement of mouse translates into exactly the same amount of  
movement on the wallboard. This is referred to pixel-for-pixel movement. In the most sensitive position,  
each pixel of movement of the local mouse translates into several pixels of movement on the wallboard  
display. This can be useful for very large displays, where movement of the mouse would be difficult  
without the translation.

All of the special key combinations are configurable from the Special keys dialog.  
Figure 19  
Special keys dialog  
Changing the default special keys is allowed to remove possible conflicts with running applications, or as  
a simple user preference. It is not possible to assign more than one function to the same special key.  
Log-In emulation is only available for a MS Windows NT/2000 OCTOPUS SERVER!  
The Options menu also has the following on/off menu items:  
Figure 20  
Toggle on/off options  
Toggling the Auto hide Octopus bar menu item will turn on or off the automatic hiding of the main  
toolbar interface when the local mouse is not in the window. A check mark denotes that the function is  
on. The default state of this item is ON.  
Toggling the Server buttons in Octopus bar menu item will turn on or off the creation of a named button  
for each server to which the OCTOPUS client is connected. The default state of this function is OFF.  
Toggling the Locator window on client desktop menu item will turn on or off the creation of a mouse-  
tracking window on the local display when the client is active. The window shows a cross-hair cursor that  
specifies the relative position of the mouse on the remote display. This can be used to determine where on  
a large display the mouse is actually being displayed. The default state of this menu item is OFF.  
Toggling the Return button (MS Win) server desktop menu item will turn on or off the creation of a big  
button on the wallboard. Clicking on that button while you are controlling the wallboard using your local  
mouse (OCTOPUS CLIENT activated) will return control to your local workstation. This as the same effect  
as using the Deactivate toggle key (default CTRL-F5). This applies only for a MS Windows NT/2000  
OCTOPUS SERVER!

4.2.9 Connecting To A Unix Server  
OCTOPUS client can connect to an OCTOPUS server that runs on a Unix bases EOS wallboard processor  
from Barco. EOS is capable of maintaining multiple simultaneous input streams and cursor images on the  
wallboard: this alleviates the need to have a queuing mechanism for OCTOPUS clients. The OCTOPUS  
client remote pointer image can also be configured so that it looks different from other users on the  
wallboard. This allows multiple simultaneous users to differentiate from one another.  
An additional option in the Options menu will appear when connecting to a Unix OCTOPUS server. All  
other menu items are always visible!  
Figure 21  
new Pointer option in menu  
The Pointer on (Xwin) Server option is only available to configure the remote pointer when connected to a  
Unix host. Selecting this option, you can choose the bitmap (from a list) for the remote pointer, its  
background and foreground color. The color of the text reflects the current background and foreground  
colors. To change them, push the Change button. This will spawn the Windows Color dialog. You can  
select any color you desire from there.

4.2.10 Not redirectable keys  
The following list of System Keys can't be redirected to the server:  
ALT-TAB  
CTRL-ALT-DEL  
CTRL-WIN-E  
WIN-BREAK  
WIN-SHIFT-M  
WIN-TAB  
WIN-E  
WIN-F  
WIN-F1  
WIN-M  
WIN-R  
WIN means the key between the CTRL and ALT key on Microsoft keyboards. For CTRL-ALT-DEL a toggle  
key can be defined via the Options menu.  
4.3 Octopus Administrator  
The OCTOPUS ADMINISTRATOR is used to define access rights for operators within a control room. This  
tool allows administrative personnel to have control over who has access to the wallboard display and  
thus, the applications being displayed therein.  
Access to the wallboard is determined by priority level. If a user with a certain priority is currently is  
using the wallboard, only users with a higher priority can take control of the wallboard away.  
Additionally, if a user does not fall into a list of allowed users, then that user's connection to the  
wallboard will be rejected.  
If a user does not have higher priority than the currently active user, then that user is placed in a wait  
queue until the currently active user relinquishes control. The Administrator client has complete control  
over the access queue and access rights, and can override the status of the wallboard at any time.  
The Administrator client uses the native NT operating system networking tools to determine access  
priorities. The NT domain names, the computer name, the user login name, and group association all tie  
together to uniquely identify users within the control room. It is assumed that the network will be  
administered, maintained and setup by professional computer personnel in a consistent manner.

4.3.1 Application Startup  
To start the OCTOPUS ADMINISTRATOR client, one need only to double click on the OCTOPUS  
ADMINISTRATOR icon, or start it from the start menu in a similar manner to the OCTOPUS SERVER (above).  
Once the application has started, you will be presented with a simple graphical user interface which will  
allow you to control access rights to a particular OCTOPUS SERVER.  
Figure 23  
Octopus Administrator main interface  
4.3.2 Connecting to an Octopus Server  
To change the access rights to a particular OCTOPUS server, you must first connect the Administrator  
client to it. This is done by selecting the Connect menu item from the Options menu. You will then be  
presented with a dialog box where you are to type the network name (or IP address) of the computer that  
is running the OCTOPUS SERVER software.  
Figure 24  
connect to Server dialog  
If you plan to connect to only one OCTOPUS SERVER (and hence, only one wallboard display), you can  
toggle the Connect to selected server at startup check box. Next time you start the Administrator client,  
you will automatically connect to that server. When successfully connected to an OCTOPUS server, the  
name of that machine will be displayed in the title bar of the Administrator client window.  
If the server is not running, the computer is down, or the network name you just typed does not exist, the  
administrator client will seem to hang for a short period. This waiting period is due to the system looking  
for that particular computer on the network and can last up to 30 seconds. After the connection is  
established, a couple of options will now be enabled. One of them is Terminate Server which, like its  
name implies, will kill the OCTOPUS SERVER (both application and service).

4.3.3 Viewing access information  
Once connected to an OCTOPUS SERVER, it possible to view the access rights defined for that server. This  
can be done by selecting the Server access... menu item from the Options menu on the main OCTOPUS  
administrator window.  
Figure 25  
servers access menu item  
Selecting this menu item will pop up a dialog box, which is where you can change the access  
prioritization of the server.  
Figure 26  
server access dialog  
The selection list on the left of the server access dialog lists each of the top-level NT domains available  
on the network. Within each of those domains, a list of computers will be available, each by name. In a  
Windows NT environment, a computer can only belong to one domain. Clicking the left mouse button  
over the + control will expand that list of computers in the list.

Figure 27  
Listing all computers in BACOEUROPE domain  
You may note that the Access list on right side of the dialog box lists all of the access rules that are in  
effect on this particular server. In this case, it reads ALL@ALL -> Users, which means all users on all  
computers have the Users group priority. By default, the Users group has a priority of five. The priority  
scale is from 1 to 9, the higher the number, the higher the priority.  
Selecting a particular computer within the domain will list all users listed on that computer within that  
domain.

Each of the happy face icons represent a user listed on this computer - domain combination  
(BARCOEUROPE\KARCLT4H). Selecting a particular user will list each of the NT groups which that user  
is a member.  
Figure 29

In this figure the user named ROK was selected, and it is shown that ROK belongs to Users groups. Note,  
that to select all users on a particular machine, one can use the username All. To determine what priority  
level each of these groups are given, you can double click on the group name.  
Figure 30  
group priority box  
You can change the priority level of this group by using the arrow toggles or by typing the desired  
priority level into the entry area. Note that changing the priority for a group will change it for all users in  
that same group listed in the access rules. Press the OK button to accept the change in priority, or Cancel  
to leave the dialog without saving the changes.  
To place a new rule in the access list, select the group that will represent this particular user and machine  
combination and then press the right pointing arrow in the center of the dialog box. This will place the  
new rule in the rules list.

4.3.4 Control Room Computer Organization  
Network identification within a control room is key to determining the roles and responsibility of  
operators. Under Windows NT, there are several pieces of information that can be used to identify an  
operator. These identifying characteristics are:  
User Name: Network name the person uses to log into the computer. This is not the login name used  
for some applications.  
Domain Name: The NT domain the user logs onto the network with.  
Computer Name: The network name of the computer.  
Group Name: Name of NT group or groups to which the user belongs.  
All of these characteristics together give the supervisor the ability to uniquely identify each operator.  
Using only a portion of those characteristics can create more general prioritization conditions.  
Rules in the access list are parsed from left to right and from specific to general  
matching criteria. First, the program attempts to find rules where the username is  
specified directly, if this fails, it then looks for rules where the user name is "All". If  
there are no matches to this point, then the connection is rejected. From the list of  
rules that have matched thus far, the computer name is matched. If there is no  
match with the computers the connection is rejected, otherwise the group name  
and priority that is in the first match is used to identify this user connection.  
A few examples of network setup should be useful to illuminate the possible applications of the  
Administration client.  
EXAMPLE: SUPERVISOR ACCESS ONLY  
This is the example where there is a relatively static wallboard, which needs to be interacted with  
infrequently, and then only by supervisory personnel. To accommodate this setup, one needs only to grant  
access to the supervisor, and deny access to all others. The OCTOPUS SERVER defaults to allow all people  
access to the wall at identical priority, this default behavior needs to be changed to support the above  
access profile.  
To do this, you must first determine which user on your systems will act as supervisor for the control  
room, with respect to the wallboard. For this exercise, this will be the user ROK on the computer  
KARCLT4H, who will be the only person with access to the OCTOPUS Server computer, KARCLT8M.  
R9830350 Octopus User Guide (2001-08)

First, one must connect to the computer KARCLT8M with the Administrator client. From the Options  
menu, select the Connect menu item:  
Figure 31  
connect to the Octopus server computer  
Once the OK button is pressed, then the dialog will disappear, and the main Administrator window title  
bar will reflect the connectivity status:  
Figure 32  
connected to the Octopus server computer  
Once connected, it will be necessary to establish the connection rules, in this case only allowing ROK to  
connect from KARCLT4H. First you must bring up the Server access dialog by selecting the Server  
access menu item from the Options menu. The server access dialog will appear:  
Figure 33  
server access dialog  
R9830350 Octopus User Guide (2001-08)

Download from Www.Somanuals.com. All Manuals Search And Download.  
In it's default state, the Administrator allows ALL users on ALL machines access under the Users priority.  
To enable restrictions, one must first remove the default open access rule from the access list. This is  
done by selecting a that particular (ALL@ALL --> Users) line in the Access list and then subsequently  
pressing the left pointing arrow button in the center of the dialog. The access rule will be removed from  
the list.  
It is now time to add the one user, ROK, who uses the computer named KARCLT4H, into the list. The  
access level is not important in this case, as ROK will be the only user to be granted access to the  
wallboard.  
First, select the domain where this user/computer resides. In our example it is in the BARCOEUROPE  
domain. Below the selected domain, all of the computers in that domain will be listed:  
Figure 34  
select KARCLT4H  
KARCLT4H, once selected, will list all users able to log into that computer in that domain. In this  
example, we will scroll down to ROK

user ROK selected with Users priority

Download from Www.Somanuals.com. All Manuals Search And Download.  
Expanding the user ROK will list all of the NT groups to which the user ROK belongs on this domain.  
Selecting a particular group and then clicking the --> arrow in the center of the dialog will place  
ROK@KARCLT4H --> Users in the access list.  
Pressing the OK button on the dialog will save those changes, pressing Cancel will leave the access list as  
it was prior to making the changes.  
If you are interested in giving a particular user access from whatever computer he/she is logged into (as  
opposed to a single computer KARCLT4H, as in the example above). One can select the item ALL from the  
list of computers in a domain, and continue as before.  
Conversely, if you are interested in giving a particular computer access rights, regardless of who is logged  
into the computer, you could add a rule such as ALL@KARCLT4H --> Users. This will allow all users on  
that particular computer access to the wallboard display with Users priority level.

4.3.4.1 User Access Management from Administrator Interface  
The OCTOPUS administrator also allows the supervisor to control access to the OCTOPUS server in real  
time. This is done via the main interface, which will list all individuals who are connected to the server,  
who currently has active control, and where each user is in queue, if there are users waiting for access.  
Figure 37  
client KARCLT8L connected to KARCLT8M  
The IP address you see next to the client is the IP address of the server it's connected to. This is necessary  
in case a client with more than 1 network card connects to a server with more than 1 network card (each  
network card has a different IP address). From this interface, a supervisor has complete control over who

has access to the wallboard. After selecting a user from the list, the following operations can be  
performed:  
Activate: Pressing this button makes that user's OCTOPUS Client interface active, and thus that user  
has control of the wallboard. If another user is currently active, then he/she is placed in the waiting  
queue.  
Deactivate: This will make a currently active user inactive. If there is someone in the waiting queue,  
then that user is promoted to an active state. If there are no waiting users, then all users are inactive.  
Disconnect: This completely disconnects a user from the server. That person's OCTOPUS Client  
interface continues to be a process on the client computer, and the user can re-connect later.
