Unit 

 

Dependency 

Set this parameter in all slave cameras similarly. 

Use only one camera as a master 

Notes 

 

  The position of the image in transport direction (Y) of each camera could 

be set separately. 
The image length is defined by the master. 

  Also the position (X + Y) and the size of the white reference could be set 

separately. 

  This parameter only takes effect if 

Global master/slave mode

 is set to

Auto-select by input 

If  more  than  one  camera  is  used,  for  example  in  print  inspection,  these  cameras  must  be 
synchronized accurately to achieve the best system performance. 

Connect line trigger / frame trigger to the master camera. 

Connect master and slave camera(s)

This function changes the sequence of the pixels within the line, i.e. the left pixels are replaced 
by  the  right  ones.  As  a  result,  the  alignment  of  the  line  with  the  direction  of  transport  is 
possible, irrespective of the camera’s installation position (pixel 1 left or right).
