1. Tíme Control (S/L)
The sequential switcher’s timing can be continuously
changed from approx, 1 to 30 seconds by turning this
control.
2. Time Internal / External Selection Switch (INT/EXT)
This switch is used to select the timing control signal
source.
INT: Select this position when the sequential
switcher’s timing is controlled using the Time
Controt(1).
EXT: Select this position when the sequential
switcher's timing is controlled by an external tim­
ing pulse.
If trigger signals from a Time Lapse VTR are connect­
ed to the External Timing Input Connector (12) when
using it in combination with this sequential switcher,
the sequential switcher will be controlled by the trigger
signals from that Time Lapse VTR.
3. Alarm Indicator
When the Alarm On/Off Selection Switch is set to the
ON position, this indicator lights.
When the alarm signal is supplied to the Alarm Signal
Input Connector in the Alarm On mode, this indicator
blinks.
4. Alarm On/Off Selection Switch (ON/OFF)
ON: Select this position when an alarm input into the
Alarm Input Connector will automatically operate
the alarm function. After a predetermining interval
of alarm operation, the norma! sequence opera­
tion is resumed.
OFF: Select this position when the alarm function is
suspended so that no alarm operation will take
place even if an alarm input is received.
In this case, a reset signal will be output from the
Reset Output Terminal (14) of the Alarm Input
Connector (7) on the back panel.
5. Sequence Output Indicators (1/2/3/4/5/6/7/8)
A lit tamp indicates that the signals of the correspond­
ing camera are available at the Camera Output
Connector.

s
a) BYPASS mode
When this switch is set to the BYPASS position,
the camera signals in this position will be skipped
regardless of the presence of a video signals
while the other camera signals will be fed out in
sequence. In other words, the signals of that cam­
era will not be fed out of Alarm Sequential Output
Connector(IO). This function may be very.conve­
nient in cases where monitoring requirements
vary from time to time.
b) AUTO mode
When the switch is set to this position, the signals
of the camera will be automatically in sequence
regardless of the presence of a video signal from
that source.
c) SPOT mode
When the switch is set to this position, the signals
of the camera in that position will be output from
of the Alarm Spot Output Connector(ll) so that
this camera signal can be selectively monitored.
During this time, sequence operation goes on and
sequence outputs are fed out from the Alarm
Sequential Output Connector(IO). If two or more
cameras are set in this mode, the signal of the
lower numbered camera in this position will be
used as output signal,
7. Alarm Input Connector (ALARM IN)
The alarm sensor closure switches are connected to
these terminals.
8. Camera Input Connectors (CAMERA IN)
These are used to connect the video output signals
from cameras. When connected, the signals will be
terminated at 75 ohms.
9. Camera Output Connectors (CAMERA OUT)
The video input signals connected to the Camera
Input Connectors (8) are looped through to these con­
nectors.
10. Alarm Sequential Output Connector (ALARM/SEQ OUT)
This is a sequential switcher output connector which
always produces sequence outputs except during an
alarm connection when the output switches to the
alarmed camera position. .
11. Alarm Spot Output Connector (ALARM/SPOT OUT)
This is a manual video switcher output connector,
which normally produces the same sequence opera­
tion output signals as the alarm sequential output.
However, if a camera selection switch is in the SPOT
MON position, that camera will be output from this
connector.
