Configuring the Camera 35
RM/TM-2040GE Series
AcquisitionStart: tells the camera to start acquiring images in the mode as specified by AcquisitionMode. This
also tells the camera to send one more image while in SingleFrameReadout.
AcquisitionStop: tells the camera to stop acquiring images.
AcquisitionFrameCount: specifies the number of frames to be acquired in the MultiFrame Acquisition mode.
Valid range is from 1 to 255.
AcquisitionRecordingWrapAround: for use with ContinuousRecording mode. When the buffer is full the oldest
recorded image will be overwritten by the newest image.
BlockBufferCount: shows the number of images recorded. The number of available Block Buffers depends on
image size, GevSCPSPacketSize, and GrbCh0AcqCfgMemoryWaterLevel. It is recommended to use at least 1440
for GevSCPSPacketSize. See “PLC Grabber Features” section 5.9.7 for a description of
GrbCh0AcqCfgMemoryWaterLevel.
BlockBufferCurrentIndex: for use with ContinuousReadout and SingleFrameReadout modes. Sets the index of
the image that would be delivered next when AcquisitionStart or Start Acquisition is executed. Index 0 refers
to the oldest image. Subsequent AcquisitionStart commands automatically increment this value. It is a write
only register so you will not see the value change.
ExposureMode: specifies mode of operation for the exposure control (or shutter). All Async modes, and
PulseWidthControl require a trigger signal. The possible options are:
•
Off: No shutter.
•
ContinuousProgrammable: Puts the camera into ContinuousProgrammable mode and enables the
ContinuousProgrammable value feature below.
•
AsyncNoShutter: this mode is meant to be used in a dark environment in conjunction with strobe light.
This setting and all settings below require a trigger signal.
•
PulseWidthControl
•
FixedExposurePIV
• PulseWidthControl_PIV
•
AsyncProgrammable: Puts the camera into AsyncProgrammable mode and enables the AsyncProgrammable
value feature below.
ContinuousProgrammable: user defined shutter time in unit of scan lines. Available only when ExposureMode is
in ContinuousProgrammable.
AsyncProgrammable: user defined shutter time in unit of scan lines. Available only when ExposureMode is in
AsyncProgrammable. Requires trigger signal.
TriggerPolarity : this feature selects which signal state, high or low, of the trigger signal will initiate an image
capture for triggered ExposureModes.
5.2 AnalogControls
These controls allow you to make adjustment to image intensities (Gain), Black Level, and channel balancing.
The camera image sensor is read out via two channels called Taps. Each channel’s Gain, and Black Level can be
independently adjusted.
