OPERATION
5.1
DWELL Key
The DWELL key is used to enter the Dwell Time
configuration menu and to enter other menus. A momentary
push will enter the Dwell Time menu. Holding DWELL for
over 1 second will enter the program mode.
5.2
SKIP/clr Key
The SKIP/clr key has two uses. The first use is to program
which cameras will be in the switching sequence. This key
toggles the displayed camera in or out of the sequence. An
"X" will be lit to the left of the selected camera number if it
is excluded from the sequence. Pressing this key while a
sequence is running will immediately remove the camera
from the sequence and advance to the next camera. An
alarm closure on a skipped camera will call-up that camera.
The second use of this key is to clear the displayed camera's
alarm call-up. The cleared camera will not be called-up again
until the alarm closure occurs again for that camera.
5.3
ALARM Key
This key is used to toggle the alarm function on and off.
When the Alarm is on:
--
The alarm indicator LED is lit and the notation "MA"
(Monitor Armed) will appear on the status line (appears
only on Monitor B for the LTC 5108 Series).
--
The switcher responds to all incoming alarms. During
the alarm period, the word "ALARM" will flash on the
status line and the alarm LED will flash.
When the Alarm is off:
--
The alarm indicator LED will not be lit and the notation
"MA" will not appear on the status line.
When the alarm function is off, the switcher will not react to
incoming alarms at that moment.
5.4
RUN/next Key
The RUN/next key serves several purposes. When multiple
alarm call-ups are present, it will sequence to the next
triggered camera. If no alarm call-ups are present and a
"hold" is present, then the key removes that hold. Lastly, if
there are no "holds" or alarm call-ups, then by momentarily
pressing the key, the sequence can be immediately advanced
to the next camera input, or by continuously pressing the
key, the sequence will rapidly sequence. The RUN/next LED
lights whenever switchers are sequencing, and goes out
whenever a HOLD is issued.
5.5
Numeric Channel Keys
These keys will issue a "hold" on their respective camera
inputs. The monitor (only Monitor B for the LTC 5108
Series) will stop sequencing (or BLANKING in the
BLANKING mode) and display that camera's video until
either:
A. Another Numeric Channel key is pressed, or
B.
The RUN/next key is pressed, or
C. An alarm call-up occurs on another camera.
If the Channel key is held down, the display of any cameras
currently in an alarm condition can be overridden.
