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 Input Signals Electrical Specifications.
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 Output Signals
Electrical Specifications for more information.
• 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.
