Upgrading one Hydra after the other
If you do not want to switch off the whole wall at once, but just one H
YDRA after the other, then a more particular
procedure is required. In this case temporarily a new wall name has to be introduced for the H
YDRA wall. Please
follow the steps below:
• Connect to one H
YDRA
• Make sure, that on the Startup tab of the Module properties dialog Show active layout on shutdown is
selected, please refer to section
5.3.4 Setup module
• Change the wall name of the H
YDRA in the same dialog on the General tab towards the new name and click
OK.
• Halt that H
YDRA; please refer to section 5.3.2 Module control.
• When the H
YDRA 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!
• Close the drive. Switch the power switch of the HYDRA off and on again. It will startup and continue to show
the last displayed layout.
Do not connect to this Hydra at that moment. First proceed with the instruction below!
• Proceed with every HYDRA, one after the other as explained for the first HYDRA.
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!
• After clearing the cache, connect to the HYDRA modules. Now the wall name of each HYDRA module can be
changed back to the original name.
• On the operator PC reset the Java Cache settings so that Enable Caching is selected.
• Check with subsection Additional actions after upgrading below.
