EXCALIBUR
SYSTEM SECURITY
Excalibur is designed for security operations. It incorporates
features to minimize the possibility that the system can be
misused. These features include operator login/logout and
access privileges. Only an operator that is logged in and has
Supervisor access privilege can minimize, switch to other
programs, or exit from Excalibur.
Minimizing Excalibur
Excalibur may be "minimized" to permit operation of other
Windows applications. Use the standard Windows control
functions to minimize Excalibur. While minimized, Excalibur
appears as an icon on the Windows Desktop and still operates
in the background. While Excalibur is minimized, other
Windows applications can be started from the Windows
Program Manager.
Task Switching from Excalibur
Excalibur allows the operator to "switch" between Windows
programs while Excalibur is operating. If another application
program is being run, such as an access control system or a
word processor for reports, the operator can switch between
Excalibur and the other program. Use the standard Windows
control functions to switch between active applications. The
operator can switch from Excalibur only to other Windows
applications that were started before Excalibur was started.
Restrictions
Only an operator with Supervisor privilege can minimize
Excalibur or switch to other applications while Excalibur is
running. (Operator privileges are set via system setup
procedures, described in the Excalibur Installation and Setup
Instructions manual, OP5500SPB.)
After minimizing or task switching from Excalibur to run
another Windows application, Excalibur still operates in the
background, monitoring for alarm conditions if armed. If an
alarm occurs during this period, Excalibur immediately
becomes the active window and displays the map and alarmed
icon. After acknowledging the alarm, the operator may then
return to the other Windows application.
Note: Although Windows fully supports task switching and
multitasking for real-time environments, it is highly
recommended that non-Excalibur applications be restricted
or not allowed at all while Excalibur is operating.
Note also that Windows Program Manager can not be closed
(to exit Windows) while Excalibur is running.
EXCALIBUR PROGRAM
Excalibur is a user interface program for AD Matrix Switchers.
It allows the operator to call and control cameras and monitors,
to control site auxiliaries, and to monitor system alarms.
To start Excalibur, open its icon from the Excalibur Program
Group. The first time that Excalibur is opened, messages may
indicate incomplete setup information (such as "No Alternate
Monitor File", page 2-7).
The first map of the map sequence is then displayed in the
Excalibur window, a button bar (page 2-8) is displayed at the
bottom, and the following menu bar is provided at the top:
Log In/Out
Video (if a PC video capture card is installed)
AD Keyboard
Preferences
Log View/Backup
About
Exit
Log In/Out
The first step in using Excalibur is to log in. The operator can
not select any functions, view any other maps, or even exit the
program until he is logged in. If any Excalibur function is
selected without logging in, an Operator Message is displayed
indicating "No Operator Logged In".
Select "Log In/Out" from the menu bar to bring up the
operator Log IN/Log OUT dialog box.
• If "Log IN" is selected, Excalibur prompts for a password.
Type in the password from the keyboard and press the enter
key. The operator password is case-sensitive and must be
entered exactly as stored via the operator setup program.
• If "Log OUT" is selected, Excalibur removes the operator's
access to the system. Log OUT does not exit the Excalibur
program. See page 2-15 to exit from Excalibur.
