interfere with another Remote Access user unconscious. Note that if a user has been
idle for 30 min he will be logged out automatically. Next user to log in will continue from
the same position in the menu system.

Remote / Local Access
It is possible to access the menu system both locally and remotely simultaneously. It is
however not possible to edit from more than one interface at a time. The first to start
edit any parameter will get exclusive access to parameter editing. This also applies to
e.g. maintenance functions. To release the exclusive access the user must navigate
out of the menu system i.e. exit the ‘Main Menu’ level.
When a remote access session is finished the user should log out from the entry
screen before closing the browser, unless intending to continue, to avoid holding the
exclusive access rights, which will block a local user from editing parameters or using
some maintenance functions. Note that the blocking also will occur in the opposite
direction.
To resolve such a blocking situation without being able to access the blocking interface
it is possible to restart the instrument using the ‘Instrument Restart’ function that can be
found in the ‘Maintenance’ menu. This function must be used with caution since it will
interrupt all instrument functions while restarting the instrument. Also note that if the
‘Start Mode’ is set to ‘Command’ the instrument will wait at start-up for a start
command from the instrument front panel or via communication.
There are a few differences between local and remote access. From the Remote
Access Interface it is not possible to do Program Upgrade (Maintenance) or Network
Configuration (Main Menu). All other functionality is available.
