PREFACE FEATURES

Panasonic sequential switchers are excellent accessories
for multi-camera security systems. The WJ-SO308 is a 8­input switcher with alarm.
This sequential switcher has two video outputs ;
alarm/sequential and alarm/spot monitor.
The alarm/sequential output displays each camera in
sequence is being displayed. The alarm/spot monitor out
put permits manual selection of any camera for display on
a second monitor; when not used, this output automatical
ly 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.
This sequential switcher also has vertical interval switching
for glitch free switching among synchronized cameras.
The length of time each camera is displayed during the

sequence is manually adjustable from 1 to 30 seconds.

1. Two video outputs ; alarm/sequential and alarm/spot.

2. Alarm/sequential output displays each camera in
sequence.

3. Front panel indicators show which camera is being
displayed.

4. Alarm/spot output for manual selection of any camera
for display on a second monitor.

5. Alarm/spot output : when not used, automatically
becomes sequential.

6. Any camera switched to the spot monitor position is
still included in the switching sequence.

7. Bypass switch skips any camera from sequence.

8. Vertical interval switching for glitch 'free switching
among synchronized cameras.

9. Switching interval manually adjustable from 1 to 30
seconds,

10. Switching interval can be externally controlled by Time
Lapse VTR or by another sequential switcher.

11. Loop-through video connectors with automatic termi

nation are provided.

12. ALARM MODE
(1) Inputs for 8 sensors : door switch, window switch,

mat switch, etc.

(2) When a sensor is activated, sequential output is

automatically switched to that camera.

(3) If two or more sensors are activated, the switcher

. automatically switches between those cameras

that are in the alarm mode.
(4) Front panel LED indicates alarm condition.
(5) Alarm can be manually reset by switch on front

panel.
(6) Automatic reset of alarm after 1 to 5 minutes inter

val (internally adjustable using VR2). Refer to the

ADJUSTMENT on page 10.
(7) Ideal mate for Panasonic Time Lapse VTR.
(8) Switcher alarm output activates Time Lapse VTR

alarm mode : VTR changes its recording speed

for greater detail during alarm period.
(9) Switcher can reset VTR alarm mode, or VTR can

reset switcher alarm mode.

PRECAUTIONS

Do not attempt to disassemble the instrument. In order
to prevent electric shock, do not remove screws or
covers. There are no user-serviceable parts inside.
Do refer all servicing to qualified service personnel.
Do not abuse the instrument. Avoid striking, shaking,
etc. It could be damaged by improper handling or
storage. Do handle the instrument with care.
Do not use strong or abrasive detergents when clean
ing the instrument body. Do use a dry cloth to clean
the instrument when dirty. In case the dirt is hard to
remove, use mild detergent and wipe gently.

Do not expose the instrument to water or moisture,
and do not operate in wet area. Do take immediate
action if ever the instrument does become wet.

Disconnect the AC adaptor from AC outlet and refer
servicing to qualified service personnel.

Moisture can damage the instrument and also create
the danger of electric shock.
Be sure to disconnect the AC Adaptor from the AC
outlet while this sequential switcher is not used.

All necessary procedures with regard to the installa

tion of this product should be made by qualified ser
vice personnel or system installers.
Do not use the instrument in an extreme environment
where high temperature or high humidity exist. Use

the instrument under conditions where temperatures

are within 14°F - 122°F (-10°C - -h50°C), and humidity
is below 95%.

MAJOR OPERATING CONTROLS AND THEIR FUNCTIONS

-2-

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.

6. 3-posltlon Selection Switches

(BYPASS/AUTO/SPOT MON)

a) b)

c)

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,

s

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.
