Security

DCN-SWAPI

What
Security measures
The installer is responsible for security measures to prevent improper use of the
system via the Internet and local wired or wireless networks.
Think of the following items to increase security:
 Prevent unauthorized access to the Central Control Unit
 Prevent unauthorized physical and logical access to the wired Ethernet
connection Central Control Unit
 Prevent unauthorized access to the DCN NG computer
 Change the default admin password
 Place the Central Control Unit in a separate VLANUse a firewall
Using the API in an ASP.NET environment.
Prerequisite:
The project build platform target should be x86.

During development
For developer environment in IIS express, the user has to place the
“Bosch.Dcn.Ecpc.Client.Logic.dll.config” file in following location:
C:\Program Files (x86)\IIS Express
After deploying
The user has to place the same “Bosch.Dcn.Ecpc.Client.Logic.dll.config” file in
the following location:
C:\Windows\SysWOW64\inetsrv

What
When installing DCN-SW on a Windows 7 PC you might get the following
notification:

This is because within the time installer checks for framework, SQLServer
installation starts which prompt for the framework installation.
Please press OK, after this the framework will be installed from the DCN-SW
installer and DCN-SW installation will install successful.
Wireless Discussion Units which are produced before 2012 need to be upgraded
using the DCN-UPTK and DLT (4.xx) in order to operate with a DCN-CCU2.
Showing voting results in PowerPoint
In case PowerPoint is used to show the voting result, it might happen that
PowerPoint starts and overlaps the user interface of DCN-SWSMV completely.
Use the Windows task bar to select DCN-SWSMV again.
Printing voting results
To print voting results, Crystal Reports needs to be installed. It is located in the
Tools directory of the DVD (CRRuntime_32bit_13_0_9.msi).

Bosch Security Systems| 2017-11-29

en | 12

Solution
During installation of DCN-SW the installation process
might not be able to find the previous SQL-server, in
case during initial installation another name for the
SQL-server was created, instead of using the default
name. Therefore it is recommended to use the default
name and folder during initial SQL-installation. If a
SQL-server with a non-default name needs to be
found, the correct name should be entered manually
in the applicable box during DCN-SW installation.
Wait until DCN-system is powered up completely and
then check the connected devices via DCN-SW
configuration application VIEW \ System Overview.

When the Master Volume of the CCU has been
changed while DCN-SW was disconnected, the DCNSW Master Volume will not reflect the CCU-setting.
Changing the DCN-SW volume setting, will make
them identical again.
Manually uninstall SWL server 2008.
Note that the DCN-SW database (the database
contains all settings like seats, meetings, synoptic
layouts, etc.) will always be removed during a
downgrade.
Due to Windows Automatic Updates some critical
components like SQL Server Express might be
temporarily not available for DCN-SW.
Do not set Automatic Updates to Automatic or restart
your system after the Automatic updates have been
installed.
Disable Stand by functionality in the Windows
operating system.
Update to version 2.80 or higher
The voting attention tone can be changed in the
voting template but becomes effective after a vote has
been selected or started.
Remove DCN-SW with DCN-SW setup and make a
new installation. Settings are stored in the SQLdatabase and can be re-used in the new installation.
Please wait at least 10 seconds to close DCNSWSMV after opening it.

Just close the error notification.

Solution
Voting legends cannot be changed into “Not Voted”.
Remove “BCPCSettings.xml” which can be found:
For XP:
“…\Documents and Settings\All Users\Application
Data\Bosch\DCN Synoptic Microphone and Voting
Software\x.xx”
For Vista:
“…\Programdata\Bosch\DCN Synoptic Microphone
and Voting Software\x.xx”
First power up the DCN-CCU2. After it is powered up,
power up the Integrus transmitter.
Note: in a system with DCN-CCU2 and other optical
devices; always first power up the DCN-CCU2 before
powering other optical devices.
Check if the DCN-SW server is not running:
1. Exit the DCN-DLT program
2. Check if the DCN-CCU2 does not report PC
on it’s display. If it does Stop the DCN-SW
server via Start\ 
SERVICES. Services (local). And check if PC
disappears.
3. Start DCN-DLT (PC will now re-appear in the
CCU2 screen, but that is correct) and start
the download.
If the download still fails, do the following:
1. Power off and open the DCN-CCU2
2. Set switch 8 of S600 to ON and power on the
CCU.
3. Download the CCU using the DCN-DLT.
4. After a succesfull download, power off the
CCU, set switch 8 of S600 to OFF again and
power on the CCU.
Do not activate another microphone until the HD
Conference Dome has reached it’s pre-position.

This notification can occur when the DCN-UPTK unit
is used extensively. Please replace the connection
cable.
During a firmware download or system reset, the
system is not in normal operation and thus the error
relays can be active.
Use a hall display or disable the voting timer.

Restart the Allegiant.

Solution
Restart the DCN-CCU or DCN-NCO.

In a system where:
1. The DCN-CCU(B)2 is connected to DCN-SW or

2. Connected to DCN-MR via Open Interface
and
3. The CCU is in Operator mode.
It will go to Open mode if:
 It loses connection with DCN-MR (e.g. the

To restore the microphone mode to Open mode, the
microphone mode needs to be set to Open mode via
DCN-SW or DCN-SWSMV.
Note: it will also go to Open mode if it loses
connection with DCN-SW or DCN-SWSMV. So that

Multi CCU systems

Windows audio
playback is lost after
installation DCN-MR
1.3. in windows XP.
System reaction is
(very) slow after
system startup.

Bosch Security Systems| 2017-11-29

Replace files msacm32.drv, msadp32.acm and
imaadp32.acm in the windows system32 folder.

The system might become (very) slow when in a multi
CCU system only the NCO is switched off and the
rest of the system stays switched on.
To prevent this problem:
Shutdown all optical devices in the Multi-CCU system.

3) Save the file in Notepad to C:\Program
Files\Bosch\Digital Congress Network\Download
and License Tool\Files with name dcn-nco.txt
4) Switch off the NCO and set dipswitch 1 of S3 to
on, set all other switches to off
5) Switch on the NCO
6) Open a command prompt (start -> run -> cmd)
and change to the following folder: C:\Program
Files\Bosch\Digital Congress Network\Download
and License Tool\Files
7) Download the NCO with the next command line
FTP with the command:
ftp -n -s:dcn-nco.txt x.x.x.x
Where x.x.x.x is the IP-address of the NCO
8) Switch off the NCO and set the dipswitches all to
off
9) Switch on the NCO
10) Start the Download and License Tool and start a
NCO download.
Switch off and on the CCU or NCO

In case system units are added to the optical ring
when the system is powered on, unexpected behavior
can occur. Only connect units to the optical network
when all units are powered off.
Select the option “enabled” in menu 4b (network
mode).
Change the slave id “--" to a number. (refer to menu
7I Multi Mode).

Solution
Connect a powered DCN Next Generation or DCN
wireless system to the transmitter or select the option
“standalone” in menu 4b (network mode)
Check whether the receiver is still working correctly. If
this is the case: the battery pack is fully charged and
can be recharged after using it a while.
If this is not the case: follow the instructions as given
in the troubleshooting table.
When changing from “single” to “multi” mode, the
DCN-CCU can remain working in “single” mode.
If this is the case follow next procedure:
1. Select “multi” on all connected CCUs
2. Switch off all CCUs.
3. Reset to defaults the NCO.
4. Switch on all CCUs.
During powering up/down a CCU in a Multi CCU
system the audio on the delegate units, connected to
the remaining CCU’s, is shortly disrupted for 1 to 2
seconds.
In case the Network Controller (NCO) in a Multi CCU
system is rebooted, the settings and configurations
changed during the past 30 seconds can be lost.
When configuring interpreter desks wait minimum 30
seconds before reboot the NCO.
Change all inputs to CH00 and then to the required
channel.
Update FPGA to version 2.03 or higher
Alternative solution:
Update firmware of the INT-TX to version 2.80
If other card readers/encoders are present or
connected to the PC please disable them.
Internal readers/encoders can be disabled in the
BIOS or in the Windows Device Manager.
Ensure that you have the required administrator
rights. Restart installation.
