To clear a sequence from a monitor, press SEQUENCE and ENTER. Only the operator who
loaded it originally (or an operator with a higher priority) is permitted to clear a sequence
from a monitor. Others receive an error message.
If enabled, the status display area of the monitor indicates the sequence number in the
appropriate location. If no sequence is currently loaded, “00” is displayed.
7.5.13 Run a Sequence
To run a sequence currently loaded on a monitor, press RUN. If the sequence was stopped,
the RUN command will initiate sequencing. The direction of sequencing is indicated in the
monitor status display (if enabled) by a directional arrow and the letter 'R' to the right of the
sequence number. If RUN is pressed while a sequence is already running, the switcher goes
immediately to the next step in the sequence, and continues to run. Holding down RUN
produces a 'quick-scan' effect. If RUN is pressed when no sequence is loaded, an error results.
If the monitor is in alarm, RUN controls the switching of alarm video rather than a loaded
sequence.
7.5.14 Stop a Running Sequence
Press HOLD to stop a sequence if one is currently running. The monitor status display shows
'S' to the right of the sequence number. If the sequence is already stopped, pressing HOLD
has no effect. If no sequence is currently loaded, pressing HOLD results in an error condition.
If the monitor is in alarm, HOLD stops the alarm switcher rather than a loaded sequence.
7.5.15 Controlling the Direction of a Sequence
The direction of a sequence can be set to run in either a forward or reverse direction. It is also
possible to manually step though a stopped sequence, either forward or reverse. These
actions work as follows:
– If NEXT is pressed with the sequence in the stop state, the sequence switches forward
and remains stopped. If the sequence is running when NEXT is pressed, it immediately
goes to the next step and continues to run. The same is true for PREV, but in the reverse
direction. If either NEXT or PREV is held down, a 'quick-scan' effect, switching at a rate of
approximately two steps per second, takes place. When sequences are first loaded, the
direction defaults to forward
– If PREV is pressed while a camera sequence is running, it reverses the sequence. If PREV
is pressed while in a hold mode and the display is showing the forward prompt, the first
push changes the direction only, and a second push switches to the previous step. The
same is true for NEXT in the opposite direction. The monitor status display shows an
arrow pointing either up or down, indicating the direction of the sequence. The arrow is
to the right of the sequence number, either above or below the sequence run ‘R’ or
stopped ‘S’ indicator. If the monitor is in alarm, PREV and NEXT control the alarm
switcher rather than the loaded sequence.
– If no sequence is loaded, pressing NEXT or PREV automatically steps the switcher
through the camera numbers in numerical order.
7.5.16 Programming a Simple Camera Sequence
The Allegiant system has very powerful sequencing capabilities. Using a system keyboard, it is
possible to enter sequences that will run on a single monitor or multiple monitors. As long as
valid camera and monitor numbers are used, they can be entered into a sequence in a
completely random order. More powerful features are available when sequences are
programmed via the PC-based LTC 8059 Master Control Software, including the capability to
activate receiver/driver actions as part of a sequence step.
