Product/function Problem Solution
DCN-SW On 64-bit operating
systems, it might
difficult to find
previous SQL-server
during DCN-SW
installation, when
initial SQL-installation
was not default.
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.
DCN-SW System overview
does not show all
connected devices
when system is still
powering up.
Wait until DCN-system is powered up completely and
then check the connected devices via DCN-SW
configuration application VIEW \ System Overview.
DCN-SW DCN-SW Master
Volume is different
from CCU volume
control
When the Master Volume of the CCU has been
changed while DCN-SW was disconnected, the DCN-
SW Master Volume will not reflect the CCU-setting.
Changing the DCN-SW volume setting, will make
them identical again.
DCN-SW Downgrade to
versions <3.10 not
possible.
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.
DCN-SW Unexpected
behaviour or no
reaction of DCN-SW.
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.
DCN-SW Generates errors after
Windows Stand by.. Disable Stand by functionality in the Windows
operating system.
DCN-SWPV Secret mode does not
work in ad-hoc voting Update to version 2.80 or higher
DCN-SWPV
Voting attention tone
cannot be changed
during a running
meeting.
The voting attention tone can be changed in the
voting template but becomes effective after a vote has
been selected or started.
DCN-SW setup
repair Error code 2869 or
Fatal error during
installation.
Remove DCN-SW with DCN-SW setup and make a
new installation. Settings are stored in the SQL-
database and can be re-used in the new installation.

Product/function Problem Solution
DCN-SWSACC Upload does not work
anymore. Restart the DCN-CCU or DCN-NCO.
DCN-MR DCN-CCU(B)2 goes
to Open mode after
closing DCN-MR
application.
In a system where:
1. The DCN-CCU(B)2 is connected to DCN-SW or
DCN-SWSMV and
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
application is stopped)
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
the meeting can still continue.
DCN-MR DCN-MR does not
connect to DCN-SW
when installed on
another PC
1. Open the Meeting Recorder.ini file with notepad
it is located here: C:\Users\[USER
NAME]\AppData\Roaming\Meeting Recorder
if the user name is administrator, the path will
be: C:\Users\
Administrator\AppData\Roaming\Meeting
Recorder
2. Find the variable NCO Ip=x.x.x.x (where x.x.x.x is
the IP address of DCN SW server) and below that
line;
Create a line DCO Ip=x.x.x.x (where x.x.x.x is the
IP address of the DCN SW server)
NCO Port=20000
NCO Ip=10.120.22.230
DCO Ip=10.120.22.230
CCU Ip=192.168.1.1
3. Save the Meeting Recorder.ini file
DCN-MR Windows audio
playback is lost after
installation DCN-MR
1.3. in windows XP.
Replace files msacm32.drv, msadp32.acm and
imaadp32.acm in the windows system32 folder.
Multi CCU systems System reaction is
(very) slow after
system startup.
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.
