KEYBOARD CONTROL
Keyboard control of matrix switching system functions is,
generally, “monitor-oriented”. A keyboard controls only those
functions associated with the monitor which is “called” to that
keyboard. System monitors which are not under keyboard
control continue to operate under control of the switching
system (i.e., alarm or event timer actions), independent of
keyboard actions.
Keyboard Passcode Entry
Passcode entry is a security procedure to allow only authorized
personnel to operate the AD1024 MegaPower II System.
When Passcode Entry is enabled by menu programming
functions (see System Options menu), the AD1676B keyboard
cannot access the system.
The passcode entry system allows a maximum of 48 users with
a separate passcode for each user. The system default
passcode is 914365, for user number 1.
Note: The default passcode should be changed to protect
against unauthorized access to the system. User passcodes
are changed by menu programming, see SET USER menu
page 4-31.
When passcode entry (USER IDS) is enabled, access is
allowed from an AD2088 or AD2079 keyboard or from the
AD5400 or AD5500 Excalibur system. The user must have a
user number and a passcode to gain control of the system. The
following Passcode Logon and Logoff procedures must be
followed to gain access to any video control or programming
functions in the AD1024 system.
PASSCODE LOGON
When an AD2088 or AD2079 keyboard is initialized and
Passcode Entry is enabled, the keyboard displays the letters
“UC” (Usercode) in the CAMERA display. This indicates
that the user must log on to the system before gaining access
to any keyboard video control or programming functions.
To log on to the system:
1. Enter the user number (1 - 64) on the keypad.
2. Press the ACK button on the keyboard.
The system then prompts for the passcode by displaying
“PSC” (Passcode) in the keyboard CAMERA display.
3. Enter the user's passcode (a maximum of six digits) on
the keypad.
(The default passcode for user #1 is 914365.)
If an incorrect passcode is entered, press the CLEAR
button, then repeat step 3.
4. Press the ACK button on the keyboard.
• If the passcode does not verify, a tone is sounded (if
keyboard sound is enabled) and “UC” is displayed
again in the CAMERA display. Press the CLEAR
button and repeat steps 1 through 4.
• If the passcode verifies, the keyboard MONITOR and
CAMERA displays are cleared. This confirms that the
keyboard is connected to the system and that a monitor
can be called to the keyboard (page 2-3).
PASSCODE LOGOFF
When the user session is completed it is advisable to log off
from the system to prevent inadvertent changes to the system
setup or current video selections.
To log off from the system:
• Enter “99” on the keypad and press the “F1” key.
