Input Line Details
The general purpose input line signals are connected to I/O lines 1 and 2, which have the following
features for control or status indication.
• Feature set: LineSelector (RW), LineName (RO), linePinAssociation (RO), LineFormat (RO),
LineMode (RO), lineDetectionLevel (RW), lineDebouncingPeriod (RW), LineInverter (RW),
LineStatus (RO).
• Connector: See 10-pin I/O Connector Pinout Details for connector pinout and electrical
information. The cable shell and shield should electrically connect the Genie Nano-5G chassis to
computer chassis for maximum EMI protection.
• Line Transition Validation: Each input incorporates a signal debounce circuit (following the
opto-couple) to eliminate short noise transitions that could be wrongly interpreted as a valid
pulse. The duration is user-programmable from 0µs to 255µs with CamExpert.
• Line Signal Propagation & Timing: Maximum delay values are defined in Input Signals
Electrical Specifications.
Trigger Overlap: Feature Details
The Trigger Overlap feature defines how the Nano-5G handles triggers that might occur more
frequently than the Frame Active period (an exposure plus readout period).
If TriggerOverlap=OFF, then triggers received before the end of the Frame Active period are
ignored. Other TriggerOverlap values are dependent on the Nano-5G model and sensor used.
TriggerOverlap=Off
• No trigger overlap is permitted.
Diagram Conditions:
• TriggerMode=On
• ExposureMode=Timed
• TriggerActivation=RisingEdge
• TriggerDelay=0
• TriggerSelector=FrameStart
• ExposureAlignment=Synchronous
