What signals are available on the Capture Connector on
the back of the camera and which of those are provided on
the standard Capture Cable?
There is a 19-pin Amphenol connector on the back of the camera that is called the
Capture Connector. The connector has the following available signals:
• Event input (an external signal can ‘mark’ one or more frames with an event
marker, making it easy to later find and view specific frames)
• Trigger input (provides a hardware trigger to the camera)
• Strobe output (is low during the frame exposure time)
• Ready output (is high when the camera is capturing Pre-trigger frames)
• IRIG-In (external sync and time stamping from a modulated or unmodulated IRIG
source)
• IRIG-Out (provides an umodulated IRIG source that contains timing information
from the camera)
• Video Out (a composite video signal, either NTSC or PAL)
• Serial Port input (for serial protocol control of camera)
• Power Out (24VDC, used to power the Break-out-Box)
• A-Sync output (optionally, signal goes low when a trigger event is detected by
the Image-Based Auto-Trigger feature, allowing for multiple cameras to be
synchronized to an event trigger)
• Pre-trigger/Memgate input (mode is set in software; if Memgate is low, acquired
frames are discarded rather than saved to camera memory; Pre-trigger signal
‘arms’ the camera and starts the acquisition of Pre-trigger frames)
Detailed information about these signals is available using the PCC application’s Help
feature.
An optional Capture Cable is available to connect to the Capture Connector and
provides access to:
• Ready
• Strobe
• A-Sync
• Pre-trigger/Memgate
• Video
All other signals are accessible by using a Phantom Break-out-Box. See the related
FAQ.
