The "Disk & Memory" tab secures controlled access to the mass memory and pre-
vents information from leaving a secure environment.
The remote commands available to control security settings are described in Chap-
ter 12.16, "SYSTem subsystem", on page 517.
USB Storage
Activates the access to external USB storage media.
To apply the change: enter the security password and confirm with "Accept". Otherwise
the change has no effect.
See also Chapter 9.9.4, "Using a USB storage device for file transfer", on page 220.
Note: Remove all USB memory devices before disabling the USB storage. If any USB
memory device remains connected, disabling is blocked, and the instrument returns a
warning message.
Volatile Mode
Activates volatile mode, so that no user data can be written on the internal memory
permanently.
In volatile mode:
●
Data that the instrument normally stores on the internal memory is redirected to
volatile memory.
●
The user directory is mapped to the volatile memory. You access the temporary
data just as data stored in the /var/user/, see Chapter 9.3, "Protecting data",
on page 201.
●
Data on the internal memory cannot be changed. It is protected against modifica-
tion or erasure.
●
You can only save data:
– Temporarily in the volatile memory
– On a connected external storage device, such as a memory stick
To activate volatile mode: enter the security password, confirm with "Accept" and
reboot the instrument. Otherwise the change has no effect.
Activated volatile mode is indicated by the icon .
Remote command:
