7.2.1 

Manual synchronization 

By default the transmission burst can be synchronized manually by dragging and moving 
the burst throughout the complete 20ms time base.  

Just  hover  the  mouse  cursor  over  our  transmission  burst  (the  cursor  will  change  to  a 
horizontal  double  arrow)  and  press  down  your  left  mouse  button.  While  keeping  the 
mouse  button  pressed,  move  the  transmission  burst  and  position  it  on  top  of  the  other 
system’s  transmission  burst.  Together  with  moving  the  transmission  burst,  also  the 
receiver and reference windows will move automatically since they have a fixed reference 
to the transmission burst. 

Figure 10 

shows the deactivator’s transmission burst having been placed exactly over the 

transmission  burst  of  another  AM  system/deactivator.  The  deactivator’s  tag  detection 
window is in a clear part of the detection band, which results in proper performance of the 
deactivator. 

7.2.2 

Automatic synchronization 

Click the Automatic synchronization button 

 to open the underlying menu. 

 

Start automatic synchronization mode 

7.2.2.1

When  this  option  is  selected,  the  software  will  detect  the  best  position  for  the 
transmission burst. Just click the Automatic Sync button and within 10 to 15 seconds the 
software will have determined the best burst offset position. 

This  option  can  only  be  used  when  other  AM  systems  or  AM  Deactivators  are  visible  in 
the synchronization screen. 

 

Temporarily disabling entrance bursts 

7.2.2.2

When you start synchronizing entrance(s), start by selecting the Synchronization page of 
the first entrance. It is very useful to switch the transmission bursts of all other entrances 
off, so you can determine if there are any other AM systems  or deactivators in the area, 
to which you must synchronize your deactivator. 

Click on the green checkmark 

 in front of the entrance/deactivator name to disable the 

transmission  burst  of  that  entrance/deactivator.  The  disabled  icon 

  will  appear, 

indicating  the  transmission  burst  for  that  entrance/deactivator  is  switched  off.  Click  this 
icon again to switch the burst on again. 

When  you  leave  the  Synchronization  page,  all  disabled  entrances/deactivators  will 
automatically start bursting again.
