2.1.8
Access control
Most pages in the user interface can be password protected with a 4-digit PIN code in order to
prevent unauthorized access.
Two access control schemes can be configured: Either one single password is used for all
password-protected pages (one access level), or two different access levels are defined (“user”
and “master”). In the latter case, the minimum access level required for each page must be
configured. It must be noted that access levels are hierarchical: The “master” password also
allows access to pages that require “user” access level. The opposite is not true: The “user”
password does not allow access to pages that require “master” access level.
When the user tries to access a protected page, a password dialog will be shown. A valid PIN
code must then be entered in order to gain access to the page.
Current permissions remain in effect until the user returns to the Home page, either manually
or automatically due to an inactivity timeout (see
on page 20).
