The following sections describe I/O functions that are available on the
NI CVS-1450 device during normal operation.

Trigger Inputs

Trigger inputs are available from both TTL inputs and isolated inputs. You
can use these trigger inputs to synchronize the NI CVS-1450 device with
an external event, such as the assertion of a signal generated by a proximity
sensor or a PLC to indicate that an inspection item is passing in front of the
camera. The NI CVS-1450 device uses this input to initiate a timed pulse
