Conference & Discussion

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.

To use the software modules, the software needs to be licensed. In order to receive licenses for the software, the keys need to be registered online.

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.

Click the Licensing button to open the Licensing page. Licensing is only required when you purchase software licenses. The Licensing page provides you with an overview of the activated licenses. Activate a license: To activate software you need to have an activation ID which was send by email after purchasing the software license. Activation requires a USB memory stick and any PC connected to the internet. Note 1: License activation is not supported for tablets. Note 2: While the same licenses are used by Dicentis Wired, the process to activate them on the Dicentis Wireless system are different, so please follow the below steps to activate the licenses on Dicentis Wireless. Insert the USB memory stick into the PC connected to the Wireless Access Point (DCNM‑WAP). Click the Add license button. Enter all required Customer information and Activation ID, click the Add license button and then the Activate button. Note: You can add more than one Activation ID. When all activation IDs are added, click the Activate button. A “save as“ dialog is shown. Save the “request file“ to your USB memory stick.  Go to the website https://licensing.boschsecurity.com using a PC/Laptop which is connected to the internet, and login. If you do not have a username, contact your local Bosch representative to acquire an account. Go to “manage license” and upload the “request file” from the USB memory stick. Save the “response file“ to your USB memory stick. In the DICENTIS web browser interface application, click the  Process response message button. Select the correct response file from the USB memory stick, and then click “Open”. Now the license is activated. New functionality is added and can be used by the system.

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.

If the document with the license key for DCN-NG was lost, there is still a way to find the license key currently loaded in a DCN-CCU2, this article shows how.

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.

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.

Time and date are set manually on the WAP. Once a month, the time needs to be set again as time drifts over time.

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.

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

Downloading firmware over the serial cable can be tricky, this document gives further information on the required equipment and settings for the serial connection and the system.

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

In order to integrate 3 rd party software with the DCN-NG system, there are 3 different integration options: Open Interface (OI) Application Programming Interface (API) Streaming Meeting Data (SMD)

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.

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.
