Switcher Control Keys; Function Keys; Telemetry Controls - Philips Allegiant LTC 8500 Series Instructions For Use Manual

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
programming.
sequence step when
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
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. 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 TC8554). 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 TC8555 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 TC8555
keyboard, the zoom function is controlled by rotating
the knob on the joystick.
