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 - The RUN key starts a sequence if one is currently
'loaded'. The RUN key is also used to exit the programming
mode and run the new sequence.
HOLD - Pressing HOLD will stop a sequence currently running.
LOCK - 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
LOCK key is also used to perform the delete function when
editing a previously programmed sequence.
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 within the key will show which key
has been pressed and therefore which mode the user is in.
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 - ON selects a receiver/driver auxiliary function at the camera
location. The ON key is also used to insert a sequence step when
programming.
OFF - OFF deselects any receiver/driver auxiliary functions
currently in the 'on' state. The OFF key also deletes the current
sequence step when programming.
SET - Press SET to record a preset scene at a remote camera site.
SHOT - Press SHOT to call up a preset scene at a remote
camera site.
PROGRAM - Use the PROGRAM key to input a camera
sequence. The PROGRAM key is also used to exit the
programming mode.
USER - Press USER to log-on and log-off the system when this
feature has been enabled by the system installer, or to select
between any of the keyboard 'user' functions. A complete list of
the 'user' functions can be found in the USER INFORMATION
section of this manual.
ALARM - Press ALARM to arm/disarm cameras and monitors.
* (star) - This key is an advanced programming feature and has
no default function. It sends a control code to the Allegiant which
will cause ERROR 96 to occur unless a custom program function
has been predefined at the Factory.

Telemetry Controls
Telemetry controls activate the camera movements. These keys
will transmit commands to receiver/drivers at remote camera sites
as long as the keys are held down. This gives the operator control
over pan/tilt and zoom lens action in addition to any auxiliary
functions used. The keyboard controls are ergonomically placed
so that the operator may operate the lens and the pan/tilt
simultaneously. As many as four pan/tilt/zoom/focus commands
(Example - Zoom In, Focus Far, Pan Left, and Tilt Down) may
be sent to a remote camera site at one time. All three zoom lens
functions can also be sent simultaneously (Example - Zoom Out,
Focus Near, Iris Open).
Pan/Tilt Control - The pan/tilt control is the joystick located on
the right side of the keyboard (or four directional buttons on the
LTC 8554/00). Move it in any one of eight directions to make
the camera indicated by the number in the camera display tilt up
or down, pan left or right, or move diagonally. The joystick of the
LTC 8555/00 keyboard is also used to provide zoom control by
rotating the knob in either a clockwise or counterclockwise
direction.
Lens Controls - The lens control buttons are switches located on
the right side of the keyboard. Push either the top or the bottom
switch to make the lens zoom in or out, focus near or far, and
open or close the iris (on applicable lenses). Zoom and focus may
be operated simultaneously. For the LTC 8555/00 keyboard, the
zoom function is controlled by rotating the knob on the joystick.
