PREFACE
Panasonic sequential switchers are excellent accessories for
multi-camera security systems, and accept the camera
inputs as;
WJ-521 up to 6 camera inputs
WJ-523 up to 10 camera inputs
WJ-527 up to 18 camera inputs
These sequential switchers have two video outputs: sequen-
tial and spot monitor. The sequential output displays each
camera in sequence; front panel indicators show which
camera is being displayed. The spot monitor output permits
manual selection of any camera for display on a second
monitor; when not used, this output automatically becomes
sequential. Any camera switched to the ‘‘spot monitor”
position is still included in the switching sequence. A
bypass switch allows any camera to be bypassed from the
switching sequence.
~The length of time each camera is displayed during the
sequence is manually adjustable from 1 to 30 seconds.
External timing is also possible. When using a Panasonic
time lapse video tape recorder the VTR can control the
switching interval so that complete pictures will always be
recorded for each camera. A trigger pulse output on the
rear panel of each sequential switcher permits one switcher
to control the timing of others, so that in a multi-camera,
multi-monitor system, the pictures on all the monitors will
change at the same time — for less eye strain and fatigue.
Moreover this model has a multi-connector on the rear
panel which can be used for displaying the number of
camera input or for controlling the spot monitor mode by
remote-controllier (local made). Tne Panasonic sequential
switchers are compact, solid state devices that require only
1-3/4" of EIA rack space. They are part of Panasonic’s
complete line of video security products, that also includes
closed circuit TV cameras, TV monitors, and video tape
recorders. |
FEATURES
1) For sequential switching of up to 6(WJ-521) or
10 (WJ-523) or 18. (WJ-527) closed circuit TV cameras.
2) Two video outputs: sequential and spot monitor.
3) Sequential output displays each camera in sequence.
4) Front panel indicators show which camera is being
displayed. |
5) Spot monitor output for manual selection of any
camera for display on a second monitor.
6) Spot monitor output: when not used, automatically
becomes sequential.

a) BYPASS mode
When the switch is set to this mode, the signals of
the camera in that position will be skipped
regardless of the presence of video signals while
the other cameras. signals will be fed out in
sequence. In other words, the signals of that
camera will not be fed out of SEQUENCE OUT.
This function may be very conveniently selected
with this switch in case places of monitoring vary
from time to time.
b) AUTO mode
When the switch is set to this mode, the signals of
the-. camera will be automatically in sequence
regardless of the presence of video signals.
Video signals are always available at the output
connector so that a VTR, etc. will also record
no-signal outputs.
This position is used when switching by use of an
external timing pulse. If trigger signals from a Time
Lapse VTR are connected to the EXT TIMING
VTR/IN input connector Q) when using it in combina-
tion with the WJ-521/WJ-523/WJ-527, the sequential
switcher will be controlled by the trigger siganis from
that Time Lapse VTR. |
In case two sequential switchers are used, set this knob
to the EXT/VTR position. (Refer to the Application

This is a manual video switcher output connector,
which normally produces the same sequence operation
output signals as the SEQUENCE output connector (8).
If more than one of the 3-position selector switches are
set to the SPOT MON mode, sequence outputs will
stop, and the signals of that’ camera which is set to the
SPOT MON mode will be produced from the output
connector.
OUTPUT; SEQUENCE
This is a sequential switcher output connector which
_ always produces sequence outputs.
EXT TIMING VTR/IN
This is an input connector for sequence operation with
external timing pulses. Connect trigger signals from a
Time Lapse VTR to this connector. If a cable is
connected to this connector, set the TIME and
EXT/VTR knob (4) to the EXT/VTR position.
The cable to be connected to the connector Q)or |

This output connector produces timing pulse signals
for switching the sequence operation. As shown in the
