MONITOR OUTPUTS 

Outputs  VIDEO  SWITCHERS  and MAIN are 
individual video outputs for connecting moni-
tor. For the correct function of the connected 
apparatus  the  signal  cables  must  have  the 
impedance load of 75

 

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 con-
tacts 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 concen-
tric  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  cycli-
cally switches among active cameras accord-
ing 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).
