Run a Sequence
To run a sequence currently loaded on a monitor, press Start Sequence [Run]. If the
sequence is stopped, the command starts sequencing. Direction of the 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 Start Sequence [Run] is pressed
while a sequence is already running, the switcher goes immediately to the next step
in the sequence. Holding down Start Sequence [Run] produces a quick-scan effect.
If Start Sequence [Run] is depressed when no sequence is loaded, an error results. If
the monitor is in alarm, Start Sequence [Run] controls switching of alarm video
rather than a loaded sequence.
Stop a Running Sequence
To sto p a sequence that is currently running, press Hold Sequence [Hold]. The mon-
itor status display shows a S to the right of the sequence number. If the sequence is
already stopped, pressing Hold Sequence [Hold] has no effect. If no sequence is cur-
rently loaded, pressing Hold Sequence [Hold] results in an error condition. If the
monitor is in alarm, Hold Sequence [Hold] stops the alarm switcher rather than a
loaded sequence.
Controlling Sequence Direction
The direction of a sequence can be set to run either forward or reverse. It is also
possible to manually step forward or reverse through a stopped sequence.
These actions work as follows:
If Next Sequence Step [Next] is pressed with the sequence in the stop state, the
sequence switches forward and remains stopped. If the sequence is running when
Next Sequence Step [Next] is pressed, it immediately goes to the next step and con-
tinues to run. The same is true for the Previous Sequence Step [Prev] button, but in
the reverse direction. If either Next Sequence Step [Next] or Previous Sequence
Step [Prev] is held down, quick-scan switching at a rate of approximately two steps
per second will take place. When sequences are first loaded, their direction defaults
to forward.
If Previous Sequence Step [Prev] is pressed while a camera sequence is running, it
reverses the sequence. If Previous Sequence Step [Prev] is pushed while in a hold
mode, and the display is showing the forward prompt, the first push changes the
direction only, and a second push then switches to the previous step.
The same is true for Next Sequence Step [Next] in the opposite direction. The mon-
itor status display shows an arrow pointing either up or down to indicate the
sequence direction. The arrow will be 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, Previous Sequence Step [Prev] and Next Sequence Step [Next] control the
alarm switcher rather than the loaded sequence.
If no sequence is loaded, pressing Next Sequence Step [Next] or Previous Sequence
Step [Prev] automatically steps the switcher through the camera numbers in numer-
ical order.
