Conference & Discussion

DCN-NG Database Backup Note the name of the database files that need to be backed up. To check what those files are called, open the “Bosch DCN Conference Software Server Console” from the Windows notification area and note the name of the active database. Shut down all DCN-NG-related programs like ‘DCN-SW Operator Application’ and ‘DCN-SW Configuration Application’. Stop the DCN-NG service; Press the Windows button and search for ‘Services’ Open the Windows Services window Select the service called ‘DCN-SW Server (DCNNG) Right click and choose ‘Stop’. Still in the Services window, stop the services ‘SQL Server (SQLEXPRESS)’ and ‘SQL Server VSS Writer’ in the same way as outlined above. Open the folder that contains the DCN-NG database. On Windows 7 and 10, it’s located by default at “C:\Program Files\Microsoft SQL Server\[MS SQL Express version]\MSSQL\data”. Replace the line between [] with the right name, this can change. Right now it’s ‘MSSQL10_50.SQLEXPRESS’ Make sure that the user that is logged in is able to read/write from/to this folder. If this is not the case, the following step will not work. It’s possible to change permissions to folders for users within Windows, but that’s outside the scope of this document. Logging in to the server with an administrator account should be sufficient. Copy the right files to a safe location – make sure to copy both the file with extension ‘mdf’ as well as with the extension ‘ldf’.   DCN-NG Database Recovery Short version: simply follow the backup steps, but copy the files back to the database folder. Shut down all DCN-NG-related programs like ‘DCN-SW Operator Application’ and ‘DCN-SW Configuration Application’. Stop the DCN-NG service; Press the Windows button and search for ‘Services’ Open the Windows Services window Select the service called ‘DCN-SW Server (DCNNG)’ Right-click and choose ‘Stop’. Still in the Services window, stop the services ‘SQL Server (SQLEXPRESS)’ and ‘SQL Server VSS Writer’ in the same way as outlined above. Open the folder that contains the DCN-NG database. On Windows 7 and 10, it’s located by default at “C:\Program Files\Microsoft SQL Server\[MS SQL Express version]\MSSQL\data”. Replace the line between [] with the right name, this can change. Right now it’s ‘MSSQL10_50.SQLEXPRESS’ Make sure that the user that is logged in is able to read/write from/to this folder. If this is not the case, the following step will not work. It’s possible to change permissions to folders for users within Windows, but that’s outside the scope of this document. Logging in to the server with an administrator account should be sufficient. Copy the right files back to the database folder  – make sure to copy both the file with extension ‘mdf’ as well as with the extension ‘ldf’. Start all services once more; ‘DCN-SW Server (DCNNG)’, ‘SQL Server (SQLEXPRESS)’ and ‘SQL Server VSS Writer’. Run the ‘Repair’ function from the DCN-SW installation package. The Repair Wizard will run through the procedure of creating a new database or selecting an already existing one. Choose the existing database; If the repair process is successful, the following window will be shown: The “Bosch DCN Conference Software Server Console” from the Windows notification area will show the system is running correctly:

When upgrading from a previous DICENTIS version that supports DANTE (V2.20 – V3.00) to the latest version 3.10, the following problem will occur; The DICENTIS system is not visible anymore in the Audinate’s DANTE controller software, where it was visible before the upgrade.

Details on the RS232 connector can be found in the installation and User Instructions manual since version 3.1x for example found in the DCN-NG software ISO under docs

Especially when using large databases it is advisable to make a backup occasionally in case something goes wrong. The manual describes ways to backup, restore and update the database quickly. This document describes how to use these options and when and also an alternative way for older versions.

If accidentally a wrong country code is chosen during setup, there is no other way to change it in except for re-doing the setup, which in effect erases all prior  changes made to the configuration. This article describes a way to set the country code without having to re-run the setup completely.

Description: The RESTful API of the CCS1000D is used in order to get a clear view of the state of the discussion devices’ microphones (amongst other things). However, when a Priority call is made, the other speakers still show as active even though they are muted in reality. Solution: This is actually as it' supposed to work. The reason the speakers still show as active is because they remain in the speaker list while the priority call comes through (in this case, the chairperson making an announcement overruling all other parties) is that in the system there’s a difference between speakers being muted and speakers being removed from the speaker list. In this case, after the priority call ends, the speakers are unmuted and can resume the discussion. It’s also possible to configure the system to stop all speakers and remove all waiting participants from the request list. If the system is setup in this way and the chairperson starts speaking, the system will indeed erase all other speakers and waiting speakers. The API can be used to create a custom interface. This means that logic can be added so the preferred outcome is created. In this case it means that the custom interface needs to poll for the speakers list but also needs to take in account that when a priority call comes through (also pollable) this means the others are muted. Using these two givens can then be used to for example change the icons of the speakers to a ‘muted’ state in the custom interface.

Audio is disrupted in a multi-CCU system, most likely after first install, re-install or reset of a multi-CCU system.

The request was to integrate an AMX NX-2200 with the CCU2. The appropriate licenses were installed, but the devices cannot communicate through the serial connection.

Trouble mixing and matching older & newer Dicentis cable assemblies, cables and connectors. The problem is usually that the cables and connectors do not fit together correctly or it's very hard to put them together.

Setting up a new system with a Integrus transmitter. As soon as the Integrus transmitter is connected to the system all kinds of problems start occurring:

In order to add authorizations to an existing license, the current license key is required as well as the new authorization numbers. How to find this key is detailed in another article: How to find the license key loaded in a DCN-CCU2 Follow the next steps for adding the new authorizations: Go to https://license.boschsecurity.com Fill in the CCU's Serial Number and CHK: Enter the current license key (this is found on the license key document received after activating the previous authorization numbers). In the following windows the license information is shown and it's possible to add additional authorization numbers. If multiple authorization numbers need to be added, choose "Next Authorization" If all authorization numbers are added, choose "Finish register" Next window will give the opportunity to register a spare CCU if applicable. A last verification is done in the next window, if things need to be changed, the process goes back to step 4. The license key with all information is shown on the next page. Note that the Print button doesn't work in all browsers, for this refer to "Printing the License Key document to PDF" Upload the license key into your CCU or NCO. The Bosch ‘download and license tool’ is to be used to upload your license into a CCU2.

Question Can a CCU be used in the same DCN-NG system as a CCU2 or CCUB2? Answer No, this is not possible. Mixing CCUs and CCU2/CCUB2s in a DCN-NG system is not supported. It’s also not possible to use a CCU as a spare unit in case of failure of a CCU2/CCUB2 in a DCN-NG system.

Unexpected behavior or no reaction of DCN-SW.

Ping messages are coming through, but the connection messages are not. This could for example have to do with a firewall blocking messages.
