Trigger Selector Details
Single Frame Trigger (Start) "FrameStart": Starts the acquisition of one frame when the
•
acquisition is active. The number of lines in the frame is defined by the feature "Height".
Trigger Source Types
Trigger Source = Line x: Select the Line Input used as an external trigger.
•
Trigger Source = Timer1End Event: Timer1 End Event is used as the internal trigger source.
•
Refer to Counter and Timer Control Category for information on those features.
Trigger Source = Counter1End Event: Counter1 End Event is used as the internal trigger
•
source.
Trigger Line Polarity: Select rising or any edge detection.
•
Input Line Details
The input line signals have the following features for control or status indication.
Feature Set: LineSelector (R/W), LineFormat (R/W), LineMode (R/W), lineDebouncingPeriod
•
(RW), LineInverter (R/W), LineStatus (RO), lineDetectionLevel.
Connector: See Connectors section for connector pinout and electrical information. The cable
•
shell and shield should electrically connect the camera's chassis to computer chassis for
maximum EMI protection.
Line Transition Validation: Each input incorporates a signal debounce circuit to eliminate
•
shot noise transitions that could be wrongly interpreted as a valid pulse. The duration is user -
programmable from 0 to 255 µs with CamExpert.
Line Input Signal Characteristics: See
•
Output Line Details
The output line signals are dedicated outputs.
Feature Set: LineInverter (R/W), outputLineSource (R/W), outputLinePulseDelay (R/W),
•
outputLinePulseDuration (R/W), outputLineValue (R/W), outputLineSoftwareCmd (R/W),
LineSelector (R/W), LineFormat (R/W), LineMode (R/W), LineStatus (RO). See
Electrical Specifications
External Outputs: Used to control external lighting or generate programmable pulses.
•
Output on Events: Each output can be set independently to one of the available event modes
•
defined by the 'outputLineSource' feature. The output delay can be set from 0 to 16 sec, in
increments of 1 µs. The pulse duration can be set from 1 to 16 sec in increments of 1 µs.
Output Line Delay Constraints
The exposure maximum delay specified by the user should not exceed the period of the signal.
•
If the exposure trigger is edge rather than level, the delay should not exceed half the period.
•
In case these conditions are violated, the camera simply ignores any new transitions / pulses /
•
triggers until the specified delay has passed.
