4 Camera Control Interface
Camera is controlled through a standard GenICam XML file. For DeviceControl , TransportLayerControl , Support
and CXP sections, please refer to the CoaxPress Version 2.0 specification.
4.1 ImageFormatControl
Xml entry Name
Address
Description
WidthMax Maximum width (in pixels) of the image. The dimension is calculated after horizontal
binning, decimation or any other function changing the horizontal dimension of the
image.
HeightMax Maximum height (in pixels) of the image. This dimension is calculated after vertical
binning, decimation or any other function changing the vertical dimension of the
image.
Width Represents the actual image width expelled by the camera (in pixels).
Height Represents the actual image height expelled by the camera (in pixels).
OffsetX Horizontal offset from the origin to the area of interest (in pixels).
OffsetY Vertical offset from the origin to the area of interest (in pixels).
PixelFormat Indicates the format of the pixel to use during the acquisition.
Mono10 uses packed data and corresponds to Genicam Mono10Packed.
4.2 AcquisitionControl
Xml entry Name
Address
Description
AcquisitionMode Controls the acquisition mode of the device.
•
Continuous: Camera internal trig
•
SingleFrame: Camera ext. IO trig
•
CoaxPress: trigger over CXP
AcquisitionStart Starts the Acquisition of the device.
AcquisitionStop Stops the Acquisition of the device at the end of the current Frame.
AcquisitionFrameRate Frame rate in Hz.
ExposureTime Sets the Exposure time (in microseconds) when ExposureMode is Timed. This controls
the duration where the photosensitive cells are exposed to light.
The camera frame acquisition is controlled by using camera XML AcquisitionStart and AcquisitionStop
commands.
The camera frame acquisition can be synchronized by 3 different ways:
•
Camera Internal Generator: ( AcquisitionMode = “Continuous”)
In this mode, the camera uses its own sync generator and generates frames continuously when
acquisition is started. Frames are generated according to
AcquisitionFrameRate value.
•
External Synchronization Generator: ( AcquisitionMode = “Single Frame”)
In this mode, the camera uses an external signal to generate frames. You must apply a TTL signal the
Sync In input of the camera. Please respect signal limits (current and voltage) and use the Aux. to BNC
adapter or respect Aux. connector pinout.
•
Synchronization over CoaXPress by Frame Grabber: ( AcquisitionMode = “CoaxPress”)
