ON LINE Display
Directly above the camera display is the ON LINE
display. The LINE part of the display indicates the
keyboard is electrically connected to the Allegiant
system. The ON display indicates the keyboard is
ready to operate. If the ON display is not lit and the
LINE is, the log-on feature of the system has been
enabled by the system installer and the keyboard is
waiting for a user to log-on to the system before
operation is permitted.
ERROR Display
The ERROR display located above the monitor
number display will light if a communication problem
occurs between the keyboard and the system. It may
also light briefly to indicate an error has occurred
when an operator has attempted to perform an illegal
or restricted activity.
Mode Displays
The Mode displays are various indicators that light
up above certain keys to show the keyboard status.
The keyboard will stay in a selected mode until all
necessary data have been entered or until the
system has timed out.
Keyboard Controls
The descriptions below indicate the function of the
key in its own mode. A key may have other functions
when used in complex modes. See the appropriate
operation section.
Numeric Keypad
This keypad is used to enter numeric data. When the
first numeric key is pressed, the camera display will
become a data display, and indicate the numeric
keys pressed.
Digits 0 to 9 - The numeric digits are general
purpose keys used to enter numeric data. Any digit
except a leading zero will appear on the camera
display. The keyboard will only recognize four
numeric digits at a time. If the data entered is not
terminated in a command in about five seconds, the
display will clear and again show the camera
number.
CLEAR Key - The CLEAR key reinitializes the
keyboard. In some cases it can be pushed twice. If
there are numeric data in the camera display, the
first push clears this data and the second push
returns the keyboard to the camera mode. This
allows the user to clear incorrect data without leaving
the current mode. If there are no data in the camera
display, the first push clears the entire keyboard back
to the default state.
ENTER Key - The ENTER key terminates
commands. It resembles the 'enter' key on a
computer keyboard, and indicates the end of numeric
data entry. Holding this key when using the ON or
OFF functions will cause those functions to repeat
until the key is released.
Switcher Control Keys
The switcher control keys control the Allegiant
switching and programming functions.
NEXT - This key serves two purposes. First, it sets a
sequence of camera switches to run in a forward
(ascending) direction. Second, it selects the next
step when programming a sequence.
PREVIOUS - The PREVIOUS key has the same
action as NEXT, except it sets a sequence to run in
the backwards (descending) direction.
RUN / EXECUTE - The RUN key starts a sequence if
one is currently 'loaded'. The EXECUTE key is used
to exit the programming mode and run the new
sequence. This is actually a single key with two
separate functions.
HOLD - Pressing HOLD will stop a sequence
currently running.
LOCK/DELETE - The LOCK key prohibits control of
a remote camera site or access to a monitor so that
other operators may not disrupt a particular camera
scene or change the monitor display. The DELETE
key is used when editing a previously programmed
sequence. This is actually a single key with two
separate functions.
ACKNOWLEDGE - This key is used to respond to a
system event such as the activation of an alarm.
Function Keys
Keyboard function keys put the keyboard in the
proper mode to correctly interpret your commands. In
most cases whenever these keys are pressed, an
indicator in the mode display will show which key has
been pressed and therefore which mode the user is
in. Additional information is provided in the Keyboard
operating section of this manual.
MONITOR - Use the MONITOR key to 'connect' your
keyboard to another monitor.
CAMERA - Use the CAMERA key to call up a new
camera to your monitor. This is the default mode of
the keyboard. The system accepts only valid camera
numbers 1 through 9999.
SEQUENCE - Use the SEQUENCE key when
'loading' a sequence onto a monitor. The system is
capable of storing up to 60 sequences.
ON / IN - ON selects a receiver/driver auxiliary
function at the camera location. The IN key is used
to insert a sequence step when programming. This is
actually a single key with two separate functions.
