DAS System User Manual
E–5
User-created files, such as saved setups, reference memories, and trigger libraries
remain in place when you save or restore an image. The files do not become part of
the saved image and are not replaced when you restore an image. Therefore, when
you convert a system from one mode of operation to another by saving then
restoring or installing new system software, existing user files that were present in
the original mode will still be present in the new mode. It is not necessary to save
the user files separately when switching modes, (although doing a backup before
such a major change is always a good idea). Likewise, saving a system software
image does not make a copy of the user files and is not a substitute for a backup.
Be aware that a saved image of system software can only be restored once. After it
is restored, the saved image no longer exists. Therefore, if you alternate between
different versions of system software, you must resave the current system software
before each restore operation. Restoring an image takes about two minutes.
The Available: field at the right of the Restore entry in the Main menu shows the
type of system software that is currently saved and available to restore, if any.
The value None signifies that there are no saved images present on the hard disk.
You will be prompted to verify your actions before the restore operation occurs. If
the restore operation cannot be carried out, you will be returned to the Main menu.
Selecting item D deletes saved images of the system software that you no longer
need. The Available: field at the right of the Restore entry in the Main menu
shows which saved images are present on the hard disk. Each image occupies
approximately 14 Mbytes of hard disk space.
You will be prompted to verify your actions before the delete operation occurs. If
the delete operation cannot be carried out, you will be returned to the Main menu.
Selecting item T lets you see or change the factory default network configuration
in a single step. The proper network settings guarantee the proper configuration
for stand-alone operation when no other network devices are attached to the
network cable that connects the instrument and the terminal.
A menu similar to Figure E–3 will be displayed. Items in the Current column are
the current settings shown in the Main menu. Items listed in the Factory column
show the settings that allow the instrument to operate in the stand alone mode.
If you want to use the default factory settings, enter Yes or Y at the prompt. The
utility will load the default settings. If you do not want to use the default
settings, enter No or N at the prompt, and you will be returned to the main menu.
