Note
Since Microsoft launched Windows XP service
pack 2 it is not possible to use DDE in a
network. To workaround you have to convert
the DDE locally to another protocol and
transport this over the network to the PC where
the VD Client is running.
The VD Client at Bosch Security Systems
Extranet does run on a Windows XP service
pack 2 network.
1.1 About Video Display
1.1.1 What is Video Display?
The Video Display module is one of the software
modules designed to be used in conferences and
discussions using the contribution equipment.
Its function is to interface the software with
conference video displays. The Video Display
module provides a means of displaying conference-
related information on video displays located in the
conference venue. The information can consist of
text, numbers and graphical elements like bar charts.
All the information displayed is generated by other
modules, and it is not possible to alter this
Video Display is unlike all other modules in that
there is no user action required to operate it. It
carries out its function - interfacing the software with
video displays - automatically. This document is
therefore not a user manual but a reference manual.
It gives information on the DDE information which
is the protocol used to transport the information from
the Video Display module to the Video Client.
information in Video Display.
i
Note
If information is to be displayed on video
displays, data must be converted within the
DCN Next Generation control PC or
transferred to a separate PC via an ethernet
link.
To use Video Display, it is necessary to have a Video
Display (VD) Client application. The VD Client
application receives the information which is passed
to it from the Video Display (server) module. The
user can change settings related to how information is
displayed on the video screens, such as text or
background colours. This can be carried out either
during or after installation of the VD Client software.
i
Note
Video Display information is available via the
windows Dynamic Data Exchange (DDE)
protocol.
A VD Client software is available at the Bosch
Security Systems Extranet or at your dealer.

3 DDE links
3.1 Introduction
The DCN Next Generation Video Display application LBB 4184 provides DDE (Dynamic Data Exchange)
links. Through these links external programs that have DDE client capability can access information regarding
the congress. The DDE server implemented in the Video Display application is a so-called “hot” DDE server.
This means that the server refreshes the DDE links whenever there is new data available. The DDE client
does not need to ask for an update. The DDE links are also made available as NETDDE links so other PCs
connected to the DCN Next Generation PC through a MS-Windows compatible network can access the
information too. Some DCN Next Generation DDE links can transmit large amounts of data. A DDE client
that wants to access DCN Next Generation DDE links must be able to deal with DDE datablocks up to 64
kilobyte in size. The VD application must be started by the user before the DDE links can be used.
3.1.1 DDE link naming conventions
A DDE link name consists of 3 parts:
1. The service name: This is the name used to address the DDE server. For DCN Next Generation
this name will always be “DCNNG”.
2. The topic name: This name identifies the class of data that must be transported across the DDE
link. For DCN Next Generation links the topic indicates which DCN Next Generation application
shall provide the data.
3. The data-item name: Topics may have more than one data-item at their disposal. This name
identifies which data-item must be sent through the link.
Example: To query the voting number
Service:
Topic:
“DCNNG”
“VOTING”
Data-item:
DDE link:
“NUM”
“DCNNG|VOTING!NUM”
3.1.2 NETDDE link naming conventions
NETDDE link names are derived from the normal DDE link name in the following manner:
1. The service name is replaced by “\\<servername>\NDDE$”. <Servername> is the network name
of the PC on which the Video application is running. (This name is determined by the Network
applet in the Windows Control Panel.)
2. The topic name is replaced by “DCNNG_<topic>$”. <Topic> is the same topic name for the link
as used for regular DDE.
3. The data-item name is the same as for regular DDE.
Example: The same link is described as in the example above, this time provided by a PC that has
the network name “VIDEO_SERVER”.
Service:
Topic:
“\\VIDEO_SERVER\NDDE$”
“DCNNG_VOTING$”
Data-item:
NETDDE link:
“NUM”
“\\’VIDEO_SERVER\NDDE$’|’DCNNG_VOTING$’!NUM”
The NETDDE part in the previous example is given in MS-Excel syntax. Other DDE client applications
might require a slightly different syntax especially for the | and ! characters and the quotes that separate the
different parts of the link-name. Refer to the documentation of your DDE client application for the exact
syntax required by your application.
i
Note
The NETDDE is not supported in Windows XP Service Pack 2. Therefore DDE should be converted
locally and then send over the network.

3.2 DDE link specifications
The following section specifies, for each available DDE link, the name and its purpose, the layout of the data
and the requirements that must be met to make the link available.
i
i
Note
If a link is available but does not have any data to transmit, each link will send an empty update. Empty
updates consist of empty strings for string parts and/or 0 (zero) values for numerical parts.
Note
Because commas are used as a separator in DDE links that transmit data consisting of several parts,
undefined behavior may occur if any string part transmitted through such a DDE link contains commas.
