2. Summary

2.1 General

OVERVIEW CONTROL MANAGER is a software to monitor and control projection systems of the OVERVIEW D series via a
graphical and intuitive user interface.

2.2 OVERVIEW D projection systems

Projection systems of the OVERVIEW D series employ a projection unit based on DLP technology and a dual lamp
illumination unit.

The sophisticated projection systems allow to be adjusted in color, brightness, luminance, and to select the
operating mode (hot standby, cold standby) as well as the active lamp. Serial numbers of the projection unit and
the illumination unit as well as the runtime of the projection unit and the lamps are stored in the system and can
be accessed and modified.

VERVIEW D offers an OnScreen Display, thus allowing controlling every individual projection system via an IR

O
Remote Control. By nature, the OSD is overlaying the applications on the display wall and does not allow
monitoring the system all the time. Moreover the OSD refers to a single unit and not to the entire display wall.

To monitor and control an O

VERVIEW D display wall, use the OVERVIEW CONTROL MANAGER software!

2.3 OVERVIEW CONTROL MANAGER software

The OVERVIEW CONTROL MANAGER software is a Java application to monitor and control projection systems of the

VERVIEW D series. Starting with Release 1.2, not only Windows platforms are supported, but also Linux and X.11.

O

Once installed, the O
Thus it is completely independent if and who logged in.

Depending on the actual requirements, the client software (OCM client) can be run in different modes allowing
different levels of interactions.

In the Operator mode, the user is informed about the status (health) of every projection system, he can switch
the entire display wall or a selected projection module on and off.

In case the projection module provide two DVI interfaces to display alternatively two sources (only for projection
systems with firmware 3.x or higher), he can select the active source.

In Service mode (advanced mode) in addition to these basic features the user can introduce new lamps into the
system (e.g. after a lamp failure and replacement of the lamp module), view and reset errors, change the
brightness target and view detailed data of system. If hot standby is enabled, the operating modus can be
selected. Color and luminance can be adjusted and multiple profiles can be created to store the current settings
and to reload them whenever wanted.

In case the projection modules provide two DVI interfaces to display alternatively two sources (firmware 3.x or
higher), in addition to the selection of the source also the switching mode (behavior on signal loss and re­establishing of the previous signal) can be selected.

For Barco technicians an extended Expert mode is provided to view and manage system data, perform
recalibration, disable over temperature protection and the dimmer, change the white peaking factor, release hot
standby operation mode and to introduce the actual lamp driver into the system when taking into operation a
display wall for the first time or after the entire wall has been upgraded with a new lamp driver.

VERVIEW CONTROL MANAGER service (OVD wall service) runs on the PC after booting the systems.

Authorization to modify and manage system data is granted after entering the correct password (independent
passwords to access the Service mode and the Operator mode).

The following chapters might give you an idea about the capabilities of O

VERVIEW CONTROL MANAGER software. For

further information please refer to the description of the user interface in chapter 7.

3.1 OCM - for operators

To be able to operate the OCM client, first of all authorization has to be given: Select
File|Authorization and enter the correct password. Subsequently the commands and
buttons will be enabled. (In case the password has already been entered as start
parameter in the short cut, you will have enabled menus and buttons from start.).

In the operator mode, the OCM allows to monitor the health of a display wall, to switch the entire display wall or
individual projection modules on or off.

The OVERVIEW D projection systems employ a dual lamp illumination system with a top lamp and a bottom lamp.
One of these lamps is the active lamp to illuminate the optics, the other one is the backup lamp (fall back in case
of a lamp failure).

The operator can check which lamp is the active one, and he may also switch the active lamp.

In case the projection modules provide two DVI interfaces to connect two sources, he can also switch between
these sources (only available with firmware 3.x or higher).

The respective actions can be selected in the Action menu. If selected, they will be executed on all projection
modules of the display wall.

In addition, the OCM client offers different views. These views are selected in the View menu. The Module View
shows the representatives of the display wall in a grid, in the Lamp View a further refinement is made: each cell
displays lamp top and lamp bottom.

In case the projection systems support two DVI inputs, Source Selection shows the active source.

By means of the context menu when right-clicking one of the items in the grid a single projection module can be
addressed and switched.

3.1.1 Monitoring a display wall

When monitoring a display wall, the main important information is about the health of the systems: Does
everything work as expected? If not – what's the problem?

The OVERVIEW CONTROL MANAGER provides a health icon in the status bar which indicates the health of the display
wall. In addition, the individual health of a projection module and the both lamps are visualized in the grid. If a
problem occurs, detailed information is given on a dedicated dialog tab.

At a glance, the status bar and the grid provide information about the health of the
system. To learn how to read it, cf. Wall Information – Health Details

Details of the problem can be found on the dialog File|Wall information:.

To open this dialog, there are three possibilities:

• Double click on the yellow icon in the status bar.

• Double click on the yellow icon in the gird.

• Select the menu command File|Wall information.

3. Getting started

On the Health Details tab, the tool tip texts (move the mouse slowly of ther information
about the problem) offers a solution.

However, these solutions require probably to run the OCM client in service mode.

As you can also see, the brightness level is indicated by different gray level:

3. Getting started

if all representatives of the projection modules in the grid have the same gray level, the display wall features
homogeneous brightness. In case the gray of the cells are different, you can see which cubes are darker (in the
example, these are the cubes A2, B2, B3). Besides you can use File|Wall Information|Health Details to find out
how much the brightness differs.

3.1.2 Switching a display wall on/off

The OVERVIEW CONTROL MANAGER enables to switch the entire display wall on/off at a simple mouse click.

It goes without saying, that it is also possible to switch a single projection module on/off.

3.1.3 Switching an individual projection module on or off

In the grid, clicking on a cell will open the context menu with the command to switch the projection module on
or off.

3.1.4 Check lamp status, determine the active lamp, change the active lamp

Projection systems of the OVERVIEW D series are dual lamp systems. One lamp is active; the other one is the
backup lamp. In case of a lamp failure, the backup lamp becomes the active lamp. However it might be desired
to change the active lamp deliberately.

The lamp view allows seeing which lamp is running and which one is in (cold or hot) standby. The context menu
allows activating the backup lamp. In case of a lamp failure, the broken lamp is indicated by a red dot.

3.1.5 Select the active source (firmware 3.x or higher only)

In case the projection modules provides two DVI interfaces to connect two sources, the active input can be
selected for all projection modules using the command Action|Source Selection.

Of course it can also be checked if a source is connected: Select View|Input sources to show input 1 and input 2
as rectangles in the grid, the left rectangle refers to input 1, the right one to input 2. In case a source is
connected, there is a green dot within the rectangle. A missing source is indicated with a red dot.

The rectangle of the active source has got a bold black border.

To change the active source for an individual projection module, use the context menu

3.2 OCM - for service

In this chapter only the additional functionalities are explained. Of course all commands and functions of the
Operator mode are also available.

3.2.1 Brightness locking

OVERVIEW D projection modules are designed with the possibility of brightness regulation: a direct illumination
sensor (DIS) measures the light output.

By means of an optical dimmer the light output of a lamp can be controlled. The dimmer can be set between the
maximum value (all light of the lamp is coupled into the light rode) and its minimum value (40% of the entire
light output).

Thus the light output can be set to and compared with a given target.

Setting all projection modules of the entire display wall to the same target results in a display wall featuring
homogeneous brightness distribution.

Of course this brightness target has to be achieved by all active lamps.

In case the active lamp changes or in case of lamp replacement this lamp may no longer fit into this target.

Also lamp aging processes might result in lamps no longer adjustable to this target.

Then of course the brightness distribution of the display wall will no longer be homogeneous.

That's why the O

Click on the Brightness locking button of the toolbar (second left button, see also tool tips). The brightness dialog pops up. When the OCM is started and the Brightness Locking dialog is opened the first time, it will show Fixed in case the display wall has a common brightness target (all projection modules set to the same target).

In case the projection modules differ in brightness target, the dialog will come up showing Disabled.

VERVIEW CONTROL MANAGER offers Brightness locking.

Barco – OverView Control Manager – DOC-3378-2 – user's manual – Revision 04 – December-2006 user mode: operator

____________________________

3-11

3. Getting started

The minimum value and the maximum value refers to the currently active lamps only!

Since the display wall shall feature a homogeneous brightness, homogeneity can only be achieved in the range
defined by the maximum light output of the darkest lamp and the minimum output of the brightest lamp.

The display wall can be run at maximized brightness (determined by the darkest lamp), minimized brightness
(determined by the brightest lamp) or at a fixed brightness target (between the maximum value and the
minimum value).

Next to the option the respective brightness values (lx) are indicated.

Option Brightness target

Disabled In case the projection systems of a display wall do not have a common brightness target, the

dialog opens with Disabled selected.

Maximized The brightness target of the display wall is always the maximum value of the darkest lamp.

Minimized The brightness target of the display wall is always the minimum of the brightest lamp

Fixed Use the slider bar to define the brightness target.

This might be recommended in case it is only one lamp which e.g. forces the max. value
down.

In case all projection systems of a display wall have the same brightness target, the dialog
opens with Fixed selected. (The value then corresponds to the value of the brightness target)

Whereas the brightness mode Maximized and the brightness mode Minimized are dynamic
targets (in case of lamp aging the target will be adjusted automatically) represents the
brightness mode Fixed a static target which might no longer be reached in case the lamps
show reduced brightness due to aging processes..

The brightness mode is indicated in the status bar.

The last applied brightness mode and the brightness target value is memorized and restored properly when the
wall service is restarted.

3-12

3. Getting started

When changing the value for Fixed, changes will be applied to the display wall as soon as the slider bar has
been released.

If Fixed is selected, and a value is set which is above the value indicated as the max. brightness or below the
value indicated for the minimal brightness, the display wall cannot be adjusted to feature homogeneous
brightness. The representative of the cubes in the grid show different gray color to indicate the different
brightness level of the cubes.

The health status will then indicate a minor problem (yellow). Use File|Wall Information|Health Details to view
the distance of the target of those projector which cannot be adjusted to the target.

3. Getting started

Please keep in mind that brightness also influences the color adjustment. In case the
brightness locking mode is e.g. set to Maximum, and the brightness shifts due to aging
processes, also the color will shift.

3.2.2 Lamp maintenance

The OCM client allows checking and viewing all relevant lamp data:

• runtime and serial number

• minimum and maximum brightness (dimmer position at 40% or at 100% open, respectively).

• operation mode

• brightness correction factor

All lamp relevant values can be viewed in the lamp property table.

3. Getting started

By means of this table, the darkest lamps can easily be identified: click on the column header Max to sort the
lamps at the criteria of max. brightness.

Barco – OverView Control Manager – DOC-3378-2 – user's manual – Revision 04 – December-2006 user mode: operator

____________________________

3-15

3. Getting started

As you can see, B3 bottom is active and has a max. of only 172 whereas B3 top has a max.
of 214.

So you might want to change the active lamp in B3 for a brighter setting of the display
wall.

By means of this property table you can also decide if you want to extra replace some lamps, e.g. in case it is a
very old lamp (sort criteria: Runtime) or a very dark on (sort criteria: Max.).

In the grid you also see when a lamp fails: it is indicated with a red dot.

Whenever a lamp fails, before replacing it, retry to ignite it again!

To do this, the OCM client offers the command Retry after fail in the context menu of the
failed lamp in lamp view.

When a lamp failure occurs redundancy is no longer given!

If the command "Retry after fail" don't ignite the lamp, it is recommended to immediately replace the lamp to
re-establish redundancy.

3. Getting started

The command Retry after fail resets the error bit and tries again to ignite the lamp.

It is often due to a temporary change in voltage that the lamp fails. Therefore it is always worth to retry it!

If it is a relatively new lamp (check runtime!) you might want to try it again later.

In case you decide to replace the lamp, after the failure of the Retry after fail command, replace the lamp as
described in the user's manual of the projection system.

After the new lamp has been inserted, reset the error bit by pressing on the ON/RES switch on the rear side of
the projection module.

Since it is a new lamp, the OCM does not know its brightness, its serial number etc.
Therefore it is recommended to "introduce it to the OCM": select the new lamp to be the
active lamp! Then the OCM can measure its data. To get the best values, first run lamp
optimization!

It is also recommended to select the command Optimize to align the position of the mirror for the new lamp.

This procedure can only be performed on the active lamp.

The display gets dark for about 3 seconds.

After this you might decide to keep the new lamp as active one or as backup lamp.

No matter whether it is the active lamp or the backup lamp: enter serial number and
runtime!

3.2.3 Color and brightness adjustment (homogeneity)

After a display wall has been adjusted with CAST, all projection modules feature a homogeneous color and
brightness distribution.

When starting the OCM client for the first time, these settings will have to be saved as Service Adjustment to
enable a customized modification of color and/or brightness.

Service Adjustment is a special profile which, if applied, will always turn the display wall into the adjustment
status done by CAST, no matter which manual modifications had been made.

It is only after the Service Adjustment is saved that the buttons for modifying color and
brightness and brightness locking get enabled.

To save the Service Adjustment profile, select Action|Homogeneity|Save as Service Adjustment.

Subsequently the buttons on the toolbar are enabled and you are allowed to change color and brightness and to
save your modifications also as a profile to be able to re-load it on the wall.

To modify color and brightness, select the button Homogeneity improve on the tool bar (third left button, see
also tool tips) or select the respective command from the context menu in Module View.

Before the dialog to modify color and brightness opens, a white test pattern should be applied to the wall. Then
the Color&Brightness dialog pops up.

3.2.3.1 Color adjustment

By means of the dialog, the current color impression of the selected projection module can be "entered" into the
color adjustment algorithm.

Example: If you consider the white of the projection module to be too green, indicate this "green-white" in the
color bitmap by double-clicking on the corresponding color. This will modify the color correction algorithm to shift
the color of the projection module towards white.

The indicated color coordinates of white as shown on top of the color bitmap will change accordingly.

In the bitmap, you have to indicate the actual color, not the desired color!

Please make sure that the color settings of your Windows desktop is set to 24bit!

In case the color you indicated is out of range, this is indicated on top of the color bitmap, and you cannot modify
the target:
