Rescaler Mode
In the
Rescaler Mode
, you can modulate the period of the external trigger signal as desired. For example, if you
supply the external trigger signal into the camera’s I/O receptacle using the conveyor’s encoder, the number of
output pulses per revolution of the encoder is fixed. In this situation, you can modulate the period of the trigger
signal received from the camera in the following manner to match the pitch of the image in vertical direction.
