2.1 Password Security
NOTE: Basic authentication is cached in Firefox and the Panel PC, so that the client is not
prompted to re-enter the password again after logging out. Closing the browser clears the
cache and prevents use by unathorized personnel.
Three levels of password security are available: Supervisor (1234), User (5678) and Viewer (0000). A
Supervisor has write access to all editable fields. A User has permission to update inventory, make volt-
ages changes and navigate through menus. A viewer can view all menus, but does not have permission
to make any changes.
The User password can only changed by the Supervisor from the web interface (see 6.12.1). Viewer login
is described in the next section.
2.1.1 Client Login Control
It is possible to have multiple users logged onto the controller. The following table shows the distribution
of allowed logins. (Both a User and a Supervisor are considered to have write access and only one can
be logged on at a time.)

2.2 Software Configuration Loading and Updates
Factory software updates and adjustments to the configuration file are possible through the Ethernet con-
nection. The Supervisor can exclude settings and groups of settings when applying changes. A partial
configuration file can also be generated and sent to the CXC (v1.81 and above).
2.3 Customizable User Interface
The web interface can be customized to remove web browser elements that are of no interest to the user.
This menu for customizing the user interface is located in Supervisor > Customize User Interface . When
a group is unchecked, all related UI elements are removed from the browser. This includes menu items,
summary information in the View Live Status and signals and alarms.
