Customizing the PxxRG_IA CAM File

Camera Parameters

As for any area-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, Vactive_Ln , HSyncAft_Tk and, VSyncAft_Ln.

For correct operation of the camera trigger overrun protection mechanism it is essential to carefully set the following parameters:

FrameRate_mHz, ExposeMin_us, ExposeMax_us and, ResetDur.

Acquisition Control Parameters

The acquisition control parameters are not customizable.

Trigger Control Parameters

As for any are-scan application, the following trigger parameters must be set according to the application needs: TrigCtl, TrigEdge, TrigFilter, TrigLine.

The trigger decimation circuit can optionnally be activated using TrigDelay_Pls and NextTrigDelay_Pls.

Interleaved Acquisition parameters

Enable Interleaved Acquisition by assigning the value ON to InterleavedAcquisition.

Interleaved Acquisition – Exposure and Strobe Timing Parameters

When Interleaved 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.

Note: In case of asymmetric exposure times, when at least one exposure time is greater than the readout time, the minimal line trigger period can be achieved when:
  • Assigning the longest exposure time to P2
  • Inserting an exposure delay prior to the lowest one

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 IOUT1 or NONE disconnects the IOUT2 output from the P2 Strobe and makes it available for another usage (Software controlled I/O).

Setting StrobeLine_P1 and StrobeLine_P2to th es ame output IOUT1 merges the two strobe pulses on the same line..

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 are-scan application, the following grabber configuration, timing and conditioning parameters must be set according to the application needs: GrabWindow, WindowX_Px, WindowY_Ln, OffsetX_Px and OffsetY_Ln.

Cluster Parameters

As for any line-scan application, the following cluster parameters must be set according to the application needs: ColorFormat, ImageFlipX and, ImageFlipY.
