    Symptoms Connection between DCN server and operator client will disconnect. This is occuring when using windows 10 PC's with SSD-disks. Diagnosis After restart of the DCN services it will work for a while. Also windows 10 has the 'fast startup' option enabled. This option will store settings and running services to have a fast startup. Because of this our services will start to fast and are not properly connected to the other services. And the use of SSD-disk in the server PC can cause a start up that is to fast for the services. Solution  In windows 10 there is the option enabled to store some services when the system has been shut down and start up again. This can cause problems with our services: 1: disable fast start-up option in the win 10 PC: go to the control panel of windows then go to 'power options' then click on 'choose what the power buttons do' then click on 'Change settings that are currently unavailable' then disable 'Turn on fast startup' Also the use of an SSD disk in the server PC can cause some startup problems with our DCN-NG software. You can fix this by doing the following: go to the services right-click on 'DCN-SW Server' click on 'Properties' Change startup type to 'Automatic (Delayed start)' Now restart the PC and test with these settings.

    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:

    Product(s) affected: DCN-NG systems with master & slave CCU set-up Version(s): all Problem description: A DCN-NG system will be installed in a building which uses different VLANs for different floors in the building. They want to be able to have interpreters on one floor (in one VLAN) and the rest of the system on another floor (in another VLAN). To this end they have connected their Master CCU to another VLAN than their Slave CCU. This set-up does not work. Question is; should this work and if not, why not? Solution: This cannot work in a DCN-NG system because of the way the system is designed. The communication between the CCU’s, at start-up of the system, uses broadcast messages which are not routed by network devices. These messages have a time-to-live (TTL) of 1, which means that once they attempt to cross into another (V)LAN, the messages are not propagated by the routing (L3) switch. The reason is that the TTL of the packet is decreased every time it traverses from one network to another. When the TTL’s value reaches 0, the packet is dropped by the routing device. Therefore, the broadcast packet will never reach the other CCU, resulting in error messages like “No Master CCU” on the Slave CCU. Therefore the system should be installed on the same (V)LAN. This usually does not pose any technical problems as (V)LANs can be distributed over multiple network devices without issue, it’s just that the predictability of where a device is physically located is less in this instance.

    DCN-NG is set-up in a multi-PC environment, all required licenses are installed. When trying to connect to the server from the secondary PC, the Operator Application takes a long time to start and once it does, the screen is simply blank and the server icon mouse-over shows the application is disconnected. When pinging the server from the secondary PC, the ping goes through without issues.

    Question I have a custom DB9 cable that uses pins 2,3 & 5. Can I use this for serial communication from the PC to the (W)CCU? Answer No. You will need a full 9-pin null cable, since the (W)CCU communication on multiple pins. Details on the RS232 connector can be found in theInstallation and User Instructions manual for version 3.1x found on the DCN-NG software ISO.

    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.
