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?
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.
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.
For some reasons it could be necessary that the the Technical Support needs this logging to analyze what could cause the trouble. This guide will help you to get through . This topic can as well be found in the Configuration Manual of Dicentis wireless page 34.
You need at least a user with access right: Configure
Logging export is not available for tablets.
The log file can only store about 1200 lines! That means you need to extract the logging after the error or symptoms occurred before the system overrides the logging line. It may be to late if you extract the logging after some days.
To send or receive a multicast Dante stream for example from different languages it will require some DCNM-LDANTE licenses but if you only need it for import and export audio signals the DCNM-LSYS includes already one channel (floor).
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.
The APS in question was running on v1.12 and needed to be upgraded to v2.60 and any firmware updates would continually fail (even other intermediate versions). The below procedure is not specific to this update and can also be used for updating from other older versions.
Network Docent scans and visualizes the network environment and is giving simple insight into all devices and cable connections of a network based system.
This Software can help you to identify network errors and find quick solutions to fix them. You even can extract an Network snapshot which is an important log file for the Technical Support.
In the next view step it will be explained how to create and extract these snapshots.
1) Open or install the Network Docent
Open Network Docent
Install Network Docent
2) Run the Network Docent
3) Export the Network snapshot
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.
Can a CCU be used in the same DCN-NG system as a CCU2 or CCUB2?
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.
Symptoms: When a meeting is recorded and the recording software (either Meeting Recorder or Open Interface connection) is shut down, the microphone control mode switches to "Open", independent of what it was before.
There could happen some occurrence were you should return your Dicentis wired license.
Reasons can be for example a hardware error, Windows software problems or an Windows upgrade of the Dicentis server etc…
Product(s) affected: DCN-NG systems with master & slave CCU set-up
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?
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.
If you are facing unknown problems with your DICENTIS wired system and you need advice from the technical support they will ask for a lot of different information.
For that reason this little program was created to make the extraction of all needed log files, system settings and other data more easily.
