Using the Remote Access
To navigate in the menu system a mouse, touch pad, pointing stick etc. must be used.
The keyboard cannot be used for navigation. Hovering with the mouse pointer over a
selection in a menu will highlight the item and clicking will open the next menu level or
allow for a parameter to be edited. The keyboard is only used when entering values like
numbers or texts. The mouse is used to select between parameter choices during set-
up.
When moving back (up) in the menu system use the ‘Escape’ button on the screen and
not the back button of the browser. This is because browsers commonly caches pages
in the PC. Since the pages from the Instrument are dynamic i.e. have a content that is
depending on the actual settings a cached page cannot be used. The instrument also
keeps track of the currently displayed page (current state) of the menu system and
does not allow for multiple pages being displayed simultaneously on different browsers
or tabs. If there is any problem with a page or a page is suspected to be cached and
not fresh from the instrument just refresh the page by clicking the refresh button or F5.
This will refresh the entire page.
Refresh button, back and forward buttons not used
Security
The internal Web Server and Ftp Server use basic authentication that will keep the
user ID and password hidden from the average computer user. It will however not
provide a secure connection, no encryption etc. It is possible with some simple
equipment and knowledge to find out the user ID and password. It is therefore strongly
suggested that the set-up and operator locks, in the instrument, are used. It is also
recommended to use the login protection on the used PC and also log out while not in
use.
Using the instrument connected to the Internet will require specific security measures
that are the responsibility of the user/network administrator.
