8.2 Upgrading
It is strongly recommended to make a backup of the system before upgrading, please refer
to section
8.1.2 Backup / restore procedures. In case that an error occurs and restoring the backup
fails, please contact the Barco support (
10.1 Hotline).
To upgrade one or multiple HYDRA modules to the current release of the iSTUDIO software, there are two different
procedures. The first procedure is less time consuming. It is explained on this page below. The second procedure
requires more time, but can be used, if it is not acceptable that the whole wall is down for a short while.
Upgrading all Hydra modules at once
• Halt all H
YDRA modules; please refer to section 5.2.5 Wall Control.
• When the H
YDRA modules stops sending an output signal open the CD-ROM drive, as explained in the HYDRA
user’s manual, take out the old iS
TUDIO CD and insert the current one.
Please be careful when inserting the CD, the CD-ROM drive closes automatically after a
while!
From iStudio release 1.9 on, changes in the communication protocol make it necessary that
no old parts of the GUI are any longer stored in the Java cache of the operator PC before
starting the new version. Otherwise the password will be misinterpreted and access to the
Hydra will not be possible!
Therefore follow the additional steps:
• Close all open browser windows
• Open: Start -> Settings -> Control Panel -> Java Plug-in -> Cache tab
• Click first the Clear button and then disable the Enable Caching checkbox. Click Apply!
• Close the drive and start the HYDRA modules as explained in section 3.2 Switching on and off.
• On the operator PC reset the Java Cache settings so that Enable Caching is selected.
• Check with subsection Additional actions after upgrading below.
