2.3 Errata

2.3.1 Integrus manual: added menu 4B Network mode

Menu 4B (Network mode) has been added. Options: • Automatic – use this when the transmitter is not

used in combination with DCN Next Generation or DCN wireless.

• Enabled – use this when the transmitter is exclusively used in combination with DCN Next Generation or DCN wireless.

When the Integrus transmitter is alternately used in combination with and without DCN Next Generation or DCN wireless, then you can use the automatic mode. In that case take care that the transmitter is switched on after the other equipment in the DCN Next Generation or DCN wireless system is switched on, else unwanted behavior can occur.



In case ‘enabled’ is selected, while no DCN Next Generation or DCN wireless system is connected, the transmitter will show the fault status “Network Error”

2.3.2 DCN-W manual: new statuses DCN-WAP The following statuses have changed or are added compared to table 11.4 of the manual.

• Off – Flashing (fast) – Off “The system prepares a software transfer to the wireless access point”, has changed into: “WAP is running boot loader software in anticipation of a download” • On – On – On “The central control unit is not compatible with the wireless access point. The central control unit does not contain the correct software”, has changed into: “Internal Error” • Off – Flashing (slow) – Off In addition to what is mentioned in the manual, it is also possible that the central control unit and wireless access point are not compatible. Check display of DCN-WCCU for more information (refer to chapter 10.6.4 of the IUI) • On – Flashing (fast) – On This indicates a new status; Internal FW download in progress

2.4 Known limitations Download & License Tool

2.4.1 Downloading DCN-WCCU and DCN-WAP might fail

When downloading a DCN-WAP and/or DCN-WCCU with an older version than 2.31: download the DCN-WCCU and DCN-WAP without any other optical device connected, else the download may fail.

2.5 Known limitations DCN-SWSMV

2.5.1 Legends in PowerPoint may return to default values

It may happen that the legends in PowerPoint return to their default values when PowerPoint is switched to presentation mode. This is due to a bug in Microsoft. Three workarounds are available: 1) First start PowerPoint and switch to presentation

mode before starting the voting in DCN-SWSMV 2) Before running DCN-SWSMV, edit the

PowerPoint presentation yourself, so that the legends are already have the correct texts

3) After running a (dummy) voting round, save the PowerPoint presentation (when the legends are correctly displayed).

2.5.2 Open the pre-defined slide in the Microsoft PowerPoint presentation failed'

If the languages of Microsoft Windows and PowerPoint are not the same, the predefined slide cannot be opened. This is a known bug of Microsoft of which the details can be found via the following link: http://support.microsoft.com/default.aspx?scid=kb;en-us;320369 Set ‘Your locale’ under Regional Options of Microsoft Windows to the language of PowerPoint.

2.6 Known limitations DCN-2.32

2.6.1 Microphone will be reset to default after a de-init.

When a de-init wired is activated at the WCCU the microphone is always set to microphone mode “open” with 2 active microphones.

2.6.2 Wireless Unit Data is cleared when performing de-init wired.

When a de-init wired is activated at the WCCU the wireless unit data (like microphone gain) is cleared.

2.6.3 Activated microphone of chairman 1 does not return after using priority button by chairman 2.

In a DCN-Wireless system it’s possible to use more than one Wireless Discussion Units as Chairman (refer to chapter 12.4.1 of the Installation & User Manual). In case chairman priority is set to ‘Temporarily Off’ in WCCU menu 4G and when more than one Chairman Unit is used, it’s possible that when the microphone of chairman 1 is active and chairman 2 presses the priority button, the microphone of chairman 1 does not switch on again, when chairman 2 releases the priority button (even though delegate microphones do come on again).

2.6.4 Abort system control with DCN-SWSMV can cause acoustic feedback.

The audio volume of the DCN-Wireless system can be controlled from the DCN-SWSMV, but this is not the same volume control as on the WCCU (refer to figure 12.1 of the Installation & User Manual). When the audio volume in the WCCU is too high and the master volume control of the DCN-SWSMV is used to reduce the audio volume to prevent acoustic feedback, the acoustic feedback will occur when the DCN-SWSMV is aborted. This is normal system behavior; it is mentioned here to remind the user.

2.6.5 Long time needed for upgrading Wireless Access Point (DCN-WAP).

The Download and License Tool can be used for upgrading. When “Down Load Optical” is selected, all applicable devices connected to the optical



network will be upgraded. In case the DCN-WAP is connected, it will take more than 30 minutes to upgrade the DCN-WAP. Bypass: In case the DCN-WAP does not need to be upgraded, do not connect the DCN-WAP when selecting “Down Load Optical”. This is normal system behavior; it is mentioned here to remind the user.

2.7 Improved functionality DCN-SWSMV

2.7.1 Remaining Battery Capacity The icon that shows the remaining battery capacity has more levels, this gives better information. Refer to the DCN-SWSMV help files.

3.4 Known limitations Download & License Tool

3.4.1 Downloading a DCN-WCCU and DCN-WAP When downloading a DCN-WAP and/or DCN-WCCU with an older version than 2.31: download the DCN-WCCU and DCN-WAP without any other optical device connected. Else the download may fail.

3.4.2 Downloading DCN-WCCU fails when Windows is not an English version

This is caused because the Download files can not be found. The Download & License tool expects that the Download files are in the following directory: %SysteemRoot%\Program Files\Bosch\Digital Congress Network\Download and License Tool\Files\ (%SystemRoot% is the drive where Windows is installed) In a non English Windows the folder "Program Files" is called differently, therefore the files are not found. The temporary workaround is:

• Log in as administrator • Go to the directory where the Download

Tool is installed “ \Program Files\Bosch\Digital Congress Network\Download and License Tool “. “Program Files” will be in local language.

• Open the with Notepad.exe the file: DownloadTool.exe.config

• Go to section <filelocation> • Within that section “ \Program

Files\Bosch\Digital Congress



Network\Download and License Tool “ is the part "Program Files" in English.

• Replace "Program files" into the name of this folder on your computer as used by Windows in your language.

• Save the file en close Notepad. • After this the Download Tool should

function. This problem is solved in release 2.32

3.5 Known limitations DCN-SWSMV














In a DCN-Wireless system it’s possible to use more than one Wireless Discussion Units as Chairman

3.6.6 No audio on Loudspeakers or Headphones of Wireless Discussion Units, or one of the enabled Microphones not working

After starting the DCN-Wireless system it might occur (seldom) that there is no audio on Loudspeakers or Headphones of Wireless Discussion Units, or one of the enabled Microphones not working. (This does not occur during operation, but only after startup)

• A temporarily solution is to restart the system

• The permanent solution is to use a DCN-WAP with HW-version 1.20 (or higher), refer to chapter 2.2.4.



4 Release 2.30

4.1 General

4.1.1 Release November 15th 2006

4.1.2 Firmware/FPGA versions Product FPGA SW FW DCN-SWSMV -- 1.10.0180 -- DCN-WCCU 2.15 2.20.1491 4.00.2075 DCN-WDxx 1.00.0000 -- -- DCN-WAP 1.00.0000 -- 2.30.01450 DCN-DDB -- 1.4.XXXX -- DCN-DDI 2.0 -- -- DCN-FCS 2.2 -- -- DCN-IDESK 1.3 1.20.1491 -- LBB 4402/00 -- 4.00.2075 PRS-4DEX4 -- 4.00.2075 LBB 4404/00 -- 4.00.2075 DCN-SWSMV 1.10





4.3 Errata

4.3.1 Integrus Manual: standby function When switching off the DCN Next Generation CCU, the Integrus transmitter indicates “Network Error” and not “standby”. However, the radiators do switch to the standby mode. When the DCN Next Generation CCU is switched on again, the Integrus transmitter and the radiators return to the “on” mode.

4.4 Known limitations DCN-SWSMV 1.10









4.5.1 RF-reflection can cause Bad Signal warnings.

The DCN-Wireless system gives a Bad Signal warning on the display of the WCCU (and on DCN-SWSMV if applicable) when the RF-signals of the system are disturbed by another system using the same frequency (for example WLAN or another DCN-W system). However it might occur that materials in the room where the DCN-Wireless system is used cause so much reflections, that it seems that there is disturbance from another system. If required, these false Bad Signal warnings can be suppressed by uploading a patch software version that will be available soon. Contact the Bosch National Sales Organization for more information.








In a DCN-Wireless system it’s possible to use more than one Wireless Discussion Units as Chairman (refer to chapter 12.4.1 of the Installation & User Manual). In case chairman priority is set to ‘Temporarily Off’ in WCCU menu 4G and when more than one Chairman Unit is used, it’s possible that when the microphone of chairman 1 is active and chairman 2 presses the priority button, the microphone of chairman 1 does not switch on again, when chairman 2 releases the priority button (even though delegate microphones do come on again).




The Download and License Tool can be used for upgrading. When “Down Load Optical” is selected, all applicable device connected to the optical network will be upgraded. In case the DCN-WAP is connected, it will take more than 30 minutes to upgrade the DCN-WAP. Bypass: In case the DCN-WAP does not need to be upgraded, do not connect the DCN-WAP when selecting “Down Load Optical”. This is normal system behavior; it is mentioned here to remind the user.

4.5.7 Text “starting” remains on WCCU In a system with an Audio Expander and an Integrus transmitter, the text “starting” can remain on the display of the WCCU after start up. On the display of the Audio Expanders 'No Network' is flashing. Switch the network mode of the Integrus transmitter to enabled and the problem will be solved.

4.5.8 Network mode disabled results in faults When the network mode of a transmitter is set to disabled, while connected to a DCN Next Generation system, noise on the loudspeakers in the DCN Next Generation system can occur. Switch the network mode of the Integrus transmitter to enabled and the problem will be solved.

4.5.9 No audio on Loudspeakers or Headphones of Wireless Discussion Units, or one of the enabled Microphones not working

After starting the DCN-Wireless system it might occur (seldom) that there is no audio on Loudspeakers or Headphones of Wireless Discussion Units, or one of the enabled Microphones not working. (This does not occur during operation, but only after startup)

• A temporarily solution is to restart the system

• The permanent solution is to use a DCN-WAP with HW-version 1.20 (or higher), refer to chapter 2.2.4.

4.5.10 Sometimes Wireless Discussion Units (WDUs), do switch ‘off’ after Out Of Range or Sleep-mode

Wireless Discussion Units can be Out Of Range of the system for 15 minutes, in case they detect the correct system within this period the connect again. The DCN-Wireless system can be in Sleep Mode, in case the WDUs detect that the system has ‘waken up’, they ‘wake up’ as well. In both situations the WDUs might switch off and do not recover, this is solved in release 2.32.

4.6 Open Interface tools and manuals not up-to-date yet

4.6.1 Open Interface manual New commands for controlling wireless settings via the Open Interface are not described yet in Open Interface manual.

4.6.2 Developers Toolkit New commands for controlling wireless settings via the Open Interface are not available and not described in Developers Toolkit yet.
