5.3.6 Login Feature When Using RS-232 Model
Keyboards
The Allegiant’s keyboard login feature is not affected by
use of RS-232 keyboards. If desired, this feature can be
enabled to provide additional security to the system.
Note that it is not possible to use the Allegiant’s Console
port login feature. The RS-232 keyboards must have
unrestricted access to the Allegiant’s RS-232 ports.
6KEYBOARD CONTROLS
6.1 Joystick
Camera positioning is controlled via an eight-way
joystick on the right-hand side of the keyboard. This
joystick is used to move a pan/tilt-equipped camera up,
down, left, right or diagonally. Rotating the ZOOM
control knob causes the lens to either zoom in or out.
The direction of its response depends upon several
factors, including the camera/lens model, and certain
system configuration settings determined at installation.
Up to four pan/tilt/zoom commands may be sent to a
remote camera site at one time (example: Zoom In,
Focus Far, Pan Left, and Tilt Down).
6.2 Focus and Iris Lens Controls
The lens control buttons are at the right side of the
keyboard. Use these buttons to control cameras
equipped with motorized zoom lenses to focus near or
far, and open or close the iris (if the lens supports
manual iris operations). Up to three zoom lens functions
can be sent simultaneously (example: Zoom Out using
the joystick knob, Focus Near, and Iris Open).
6.3 Numeric Keypad
Use the numeric keypad when it’s necessary to enter a
numeric value, for instance, Camera numbers, Monitor
numbers, user number, or password information.
Leading zeros are not necessary when entering a
number.
6.4 "*"(Star) Button
The ‘*’ key is used to activate an advanced programming
feature in the Allegiant CPU. It has no default function,
and will cause ERROR 96 to occur unless an associated
Command Script has been programmed into the
Allegiant.
6.5 Other Keyboard Buttons
See the Operating section of this manual.
6.6 Keyboard Displays
The keyboard has two groups of seven-segment LED
displays. The monitor LED display is a three-digit
display that shows the number of the monitor currently
being controlled by the keyboard. During certain
operating modes, it may also display prompts and
diagnostic information.
The camera LED display is a four-digit seven-segment
display that shows the number of the camera being
viewed on the monitor that the keyboard is controlling.
There are three modes for this display; camera mode is
the default, but when the operator pushes one of the
numeric data keys, the display shows the numeric
keystrokes as entered from the keyboard, and also causes
the decimal point, in the lower right-hand side of the
camera display, to light. If the keyboard remains inactive
for about five seconds, the camera display returns to
default mode and again displays the camera number.
The third mode is for error display (refer to Error
Messages). When the operator enters an erroneous key
sequence, the keyboard beeps and an error number is
temporarily displayed (for approximately 2 seconds).
