Customizing the LxxxxRG_IA CAM File
Camera Parameters
As for any line-scan camera, the following camera parameters must be set according to the selected camera model:
Spectrum
, TapConfiguration
, TapGeometry
, ColorMethod
,
DvalMode
, ResetEdge
, CC1Usage
, CC2Usage
, CC3Usage
,
CC4Usage
, Hactive_Px
and, HSyncAft_Tk
.
For correct operation of the camera trigger overrun protection mechanism it is essential to carefully set the following parameters:
LineRate_Hz
, ExposeMin_us
, ExposeMax_us
and, ResetDur
.
Acquisition Control Parameters
As for any line-scan application, the following acquisition control parameters must be set according to the application needs:
AcquisitionMode
, TrigMode
, NextTrigMode
, EndTrigMode
,
BreakEffect
, SeqLength_Pg
, SeqLength_Ln
and, PageLength_Ln
.
Trigger Control Parameters
As for any line-scan application, the following trigger and end trigger control parameters must be set according to the application needs:
TrigCtl
, TrigEdge
, TrigFilter
, TrigLine
, EndTrigCtl
,
EndTrigEdge
, EndTrigFilter
and, EndTrigLine
.
Interleaved Acquisition parameters
Enable Interleaved Line-scan Acquisition by assigning the value ON
to InterleavedAcquisition
.
Interleaved Acquisition – Exposure and Strobe Timing Parameters
When Interleaved Line-scan Acquisition is enabled, the following exposure and strobe parameters are irrelevant:
Expose_us
, ExposeTrim
, StrobeMode
, StrobeDur
and,
PreStrobe_us
.
Instead, the exposure and strobe timings must be defined for P1 and P2 using the following parameter set:
ExposureTime_P1_us
, ExposureTime_P2_us
, StrobeDuration_P1_us
,
StrobeDuration_P2_us
, StrobeDelay_P1_us
and, StrobeDelay_P2_us
.
Interleaved Acquisition – Exposure Delay Parameters
By default, MultiCam configures P1 and P2 with the smallest possible Exposure Delay value. This setting is satisfactory for the use cases where the exposure time is shorter than the readout time.
Optionally, keeping ExposureDelayControl
set to MAN
, you may manually change the minimum exposure delay value
of P1 and/or P2 using the ExposureDelay_MAN_P1_us
and ExposureDelay_MAN_P2_us
parameters.
Alternatively, you may also change ExposureDelayControl
to one of the automatic control methods:
SAME_START_EXPOSURE
or SAME_END_EXPOSURE
.
With SAME_START_EXPOSURE
, the start of exposure is delayed by the same amount of time for both programs: both exposure delay
values are equal.
With SAME_END_EXPOSURE
the end of exposure is delayed by the same amount of time for both programs.
- Assigning the longest exposure time to P2
- Inserting an exposure delay prior to the lowest one
Encoder Control Parameters
As for any line-scan application, the following encoder control parameters must be set according to the application needs:
LineCaptureMode
, LineRateMode
, Period_us
, PeriodTrim
,
LinePitch
, EncoderPitch
, ConverterTrim
, OnMinSpeed
,
LineTrigCtl
, LineTrigEdge
, LineTrigFilter
, LineTrigLine
,
RateDivisionFactor
, ForwardDirection
and, BackwardMotionCancellationMode
.
Interleaved Acquisition – Strobe Control Parameters
The StrobeLine_P1
and StrobeLine_P2
parameters designate the I/O lines used as strobe outputs for P1 and P2
respectively. The default values are IOUT1 for P1 and IOUT2 for P2.
Setting StrobeLine_P2
to NONE
disconnects the IOUT2 output from the P2 Strobe and makes it available for
another usage (Software controlled I/O).
The StrobeOutput_P1
and StrobeOutput_P2
parameters control the delivery of the strobe pulse for P1 and P2
respectively. The delivery is enabled by default. Assigning the DISABLE value, inhibits the delivery of the strobe pulse.
Grabber Timing Parameters
As for any line-scan application, the following grabber configuration, timing and conditioning parameters must be set according to the
application needs: GrabWindow
, WindowX_Px
and, OffsetX_Px
.
Cluster Parameters
As for any line-scan application, the following cluster parameters must be set according to the application needs: ColorFormat
and, ImageFlipX
.
