Programmable video switchers VPP404,
VPA404, VPA408 is a apparatus, which enables displaying of 4 or 8 cameras on one
output.
The switching can be provided manually or
with the help of programmed sequence. It is
possible to set up cameras, which are at the
right time available for automatic switching.
This makes possible to disconnect temporarily uninteresting or disconnected cameras.
An operator attention can be focused only on
important camera images.
The video switchers VPA404 and VPA408
contains 4 (8) alarm inputs. The video
switchers itself remembers the last setting of
active cameras, a programmed sequence
and the time of switching an alarm output,
even after the unit had been switched off.
MAIN CHARACTERISTICS
o 4 (8) video inputs
o 2 identical video output
o on screen menu control
o programmable switching sequence
for the monitor output
o alarm input for each video input
o potentialless alarm output *
o 2 alarm setting modes *
o acoustic and optical alarm signaling *
* for VPA404 and VPA408 only

INSTALLATION SWITCHERS CONTROLLING
MONITOR OUTPUTS
Outputs VIDEO SWITCHERS and MAIN are
individual video outputs for connecting monitor. For the correct function of the connected
apparatus the signal cables must have the
impedance load of 75Ω.
ALARM INPUTS
One alarm input is suitable for one video
input. Alarm loops are connected between
alarm input and common conductor - ground
(GND).
ALARM OUTPUT
Video switchers has its own potentialless
alarm output made of the normally open contacts of the relay.
ALARM CONNECTOR
Alarm connector is used for connecting
alarm inputs and outputs. The connection of
25 outlet connector CANNON is illustrated on
the pictures 5 and 6 (page 4).
POWER SUPPLY INPUT
The video switchers VPP404, VPA404 and
VPA408 are supplied from a uniflow supply
of 12 V. Energy input is 4 W maximum. For
connecting supply voltage is used a concentric connector 5,5 x 2,1 mm. The positive
supply pole is on the inside contact of the
concentric connector, the connector jacket is
the negative pole.
BASIC MODE
After turning on, the video switchers cyclically switches among active cameras according to the sequence, which has been set up.
The automatic switching is signaled by the
SEQ light-emitting diode (LED), the camera
displayed on the main video output (MAIN) is
signaled by the diode of the buttons 1 – 8.
MANUAL SWITCHING
Press the corresponding button to display
cameras 1 – 8.
AUTOMATIC SWITCHING
The automatic switching starts by pressing
the button SEQ.
If the video switchers does not start to switch
automatically, check the camera settings in
the menu SEQUENCE and TIME (page 6).

VIDEO SWITCHERS CONTROLLING (continuation)
Video switchers contain a graphical menu,
which enables the setting of the following
functions.
o Cameras activation for automatic
switching
o Switching period set up
o Alarm functions set up
MENU - MAIN MENU
To display the main menu on the screen
press the button MENU. Choose the required
function by pressing the buttons 1, 2 and 3.
TIME – SWITCHING PERIOD
By using the buttons 1 and 3 (1 and 5 by
Q8M) is possible to prolong or slow down the
switching time among individual cameras
and video switchers pictures, at intervals 1 –
99 sec.
ALARM – ALARM SET UP
SEQUENCE – CAMERAS ACTIVATION
By pressing the button 1 is the menu for
cameras activation and deactivation for
automatic switching displayed.
By pressing the buttons of individual cameras activate or deactivate automatic switching cameras. Activated cameras are marked
by sign .
If the cameras are set up, the video switchers will switch automatically among cameras
1, 2, 3, 4, …
In case you make a mistake by sequence
programming (none or only one camera is
active) and you start the switching sequence
by pressing the button SEQ on the front
panel, notice „INCORRECT SEQUENCE“
will appear. In that case is necessary to set
up cameras in the SEQUENCE menu properly.
The video switchers detects an alarm, when
the connection is provided between the
alarm input 1 – 8 on the CANNON connector
of the back panel and the common conductor – ground (GND). By the help of the buttons 1 and 3 (1 and 5 Q4M) set up video
switchers reaction for an alarm. The reaction
can be:
OFF - alarm is off - video switchers
does not respond to the alarm.
FOLLOW - video switchers signalizes an
alarm as long as any alarm input is active.
2-255 S - video switchers signalizes an
alarm for the set up time since
the alarm event had occurred.
If an alarm occurs, the video switchers
makes the following steps:
1. it switches the alarm output (relay) – signaled acoustically (beep).
2. it switches a camera corresponding to the
alarm input for the set up time.
The alarm stops after the end of the set up
time interval, after pressing any button or

after the end of the alarm event in the mode

YOUR TROUBLE THE CAUSE AND ITS SOLUTION
After connecting the supply voltage device does
not work.
After connecting the supply voltage the LEDs are
on, but the device does
not work.
Automatic switching sequence cannot be
switched on.
Device does not react to
alarm inputs.
There is no picture on the
monitor.
The power supply is not connected.
Check the supply connector and the polarity of power supply.
Switch on the power breaker.
The supply adapter is not dimensioned sufficiently.
Check if the adapter power output and voltage agree with the
video switchers requirements.
The supply adapter is not dimensioned sufficiently.
Check if the adapter power output and voltage agree with the
video switchers requirements.
Cameras listed in the switching sequence are off from the switching.
Correct the sequence and check the sequence period (page 6).
The alarm processing is switched off in the main menu.
Set up the alarm with the function of ALARM (page 6).
The connection of the alarm signals is disconnected.
Check the connection of the alarm connector.
The video switchers and monitor patchcord is defective.
Check the patchcord carefully.
