The Digital I/O chapter covers the features required to control the general Input and Out-
put signals of the device.
Trigger (Line Selector → Line 0 / Line 1) (General Information)
Trigger signals are used to synchronize the camera exposure and a machine cycle or, in
case of a software trigger, to take images at predened time intervals.

Each trigger source must be activated separately. When the trigger mode is activated, the
hardware trigger is activated by default.

Trigger Delay:
The trigger delay is a
exible user-dened delay
between the given trigger
impulse and the image
capture. The delay time
can be set between 0.0
μs and 2.0 s in increments
of 1 μs. Where there are
multiple triggers during the
delay, the triggers will also
be stored and delayed. The
buffer is able to store up to
512 trigger
signals during the delay.
Your benets:
▪ No need for an external
trigger sensor to be perfect-
ly aligned
▪ Different objects can be
captured without hardware
