Panasonic WJ-SQ308 - Manual (Page 6)

12. External Timing input Connector (EXT TIME IN)
This input connectors for sequence operation with
external timing pulses. Connect the trigger signals
from a Panasonic Time Lapse VTR to this connector.
13. External Timing Output Connector (EXT TIME OUT)
This connector outputs timing pulse signals which are
synchronized with the sequence operation. As shown
in the system application examples, two or more
switchers may be used together in either a synchro­
nized or asynchronous manner. When synchronized,
the External Timing Output Connector of one switcher
(the Master unit) is connected to the External Timing
Input Connector the second unit (the Slave unit). The
Slave unit's TIME INT/EXT SELECTION SWITCH
should be set to the EXT position. The Master unit’s
TIME INT/EXT SELECTION SWITCH may be to either
INT or EXT, depending on whether a Time Lapse VTR
used.
14, Reset Output Terminal (RESET OUT)
This terminal is connected to the Alarm On/Off
Selection Switch (4). When setting the Alarm On/Off
Selection Switch (4) to the OFF position and connect­
ing the reset terminal of the Time Lapse VTR to this
terminal, the alarm function will stop.
15, Recover Input Terminal (RECOVER IN)
When this is connected to the recover output terminal
on the Time Lapse VTR, this switcher will stay in the
alarm mode as long as the Time Lapse VTR stays in
its alarm mode. After that, normal sequence operation
is resumed.
Note: Time Lapse VTR alarm mode must be set for a
minimum of 60 seconds for this feature to func­
tion.
1. The External Timing Output Connector(13) and Alarm
Output Terminatile) are open collector outputs. They
will not operate unless loads are connected to them
externally and DC power (not to exceed (Max.30V
100mA) is supplied externally.
2. When the Alarm On/Off Selection Switch (4) is set to
the OFF position, the alarm mode wilt not operate even
if an alarm input is received. When the sequential
switcher is connected to the Time Lapse VTR, the
alarm will not operate if either of them has its alarm
selector in the Alarm OFF (Reset) position.
3. If the Alarm Spot Output Connector (11) is used for
monitoring and if any one of the 3-position Selection
Switches (6) is in the SPOT MON position, only the
signal of the camera which is in the SPOT MON mode
will be output, even during an alarm condition. If none
of the 3-position Selection Switches are in the Spot
Mon position during an alarm condition, the Alarm
Spot Output Connector will output the alarmed camera
position.
4. Alarm Time Control is preset for 60 second duration at
the factory.
However, this duration can be varied within the range
of 1 to 5 minules.lt is varied by turning the internal
Alarm Time Control VR2.
CAUTIONS
16. Alarm Output Terminal (ALARM OUT)
If this terminal is connected to the alarm input terminal
on the Time Lapse VTR, the Time Lapse VTR will be
automatically switched over from long-time recording
to normal-time recording at the same time as this
switcher starts alarm operation. "ITiis terminal is an
open collector output, to which loads of up to 30V
100mA can be connected. Thus it may be used for
controlling an alarm device by using a relay, for exam­
ple.
If this terminal is connected to the detection connector
on the time-date generator WJ-810, the cumulative
number of alarms and the time of the last alarm are
indicated.
17. Adaptor Connector (DC 9V)
Connect an AC Adaptor (supplied) to this connector.
