Resolution

Always begin any modification to the loaded file in a digital signal processor by launching the Bose ControlSpace Designer software, retrieving the running file (System > Retrieve Saved Design), and saving it safely to the computer where it can be easily found and reloaded.

(Detailed Instructions for this step can be found in the online Help file under the header "Maintaining Your System" and the subtitle "Retrieving System Configuration".)

2. Right click on the newly retrieved file, select "Open With," and then choose a web browser such as Internet Explorer or the Notepad utility. These programs can display the configuration text of the design file. Near the beginning of the text, Project Version ="x.xx" will appear. This indicates the version of the software that was running at the time the file was loaded. After the file version has been identified, you can close Notepad or the browser that was used to find it.

3. If the version above is not already loaded on the computer, it can be downloaded from the www.boseprofessional.com website: navigate to the ControlSpace software page, select the Downloads tab, and locate the version of the software identified in step 2 above. Download and install this version.

4. With ControlSpace Designer software, scan the processor (Tools > Scan). If all addressing matches (same IP range and subnet mask on the computer's NIC card and CSD project address that matches the ESP/EX processor), an icon will appear in the Project View. Send this file to the processor (Tools > Go online). This blanks out all programming.

5. Go offline (Tools > Go offline), launch the latest version of ControlSpace Designer, and perform a firmware upgrade via the Hardware Manager (found in the System drop down menu).

6. After successfully updating the FW, open the file retrieved in Step 1 inside the newer version of ControlSpace Designer, and reload the file (Tools > Go online).

Why did this happen?

Every new version of ControlSpace Designer carries with it updated firmware. This allows for different methods of compiling the various processing blocks to create a transfer function that matches your desired application. When a firmware update is conducted and the older file remains in the processor, there is sometimes a mismatch in how the processing blocks handle information versus the new firmware. Unpredictable behavior can result. By loading a blank file first, upgrading the firmware, and then reloading the desired running file now having been compiled in the updated version, these anomalies are avoided.
