11 Regardless of if your cable ends up being longer or shorter than 3 meters,all cable wires must be of equal length due to the extremely sensitivetiming characters of the Frame Grabber and Digital Camera interface. The PXD Configuration Application Imagenation provides a program called PXD Configur...

Clocks from Data to Hsync: number of clocks from last pixel on theline to following horizontal sync. v. For cam...

15 Digital Frame Grabber Information The WEN Signal This single is an input to the frame grabber from the camera and istypically treated as a FTV (Field Data Valid). This signal is available onI/O line 1. The signal can be set to trigger a grab using theSetTriggerSource function. Data line Options 8...

16 to debounce this signal. The debounce flag can be set using theSetTriggerSource function. If the debounce flag is set then two triggersignals are required. One signal is set to TRIGGERP line 14 of the I/Oconnector. The other is sent to TRIGGERN line 15 of the I/O connector.By sending the signal t...

17 Pixel Clock Source Most digital cameras provide their own pixel clock to the frame grabber but insituations where a custom frame and pixel rate are required, the frame grabbermust create the pixel clock for the camera. A pixel clock source provides moreflexibility for the system integrator.

18 Pixel Swizzling The second aspect of multi-channel cameras that can cause problems for digitalframe grabbers is the ordering of the received pixels. Figure 1 illustrates how theDalsa CA-D4 two-channel camera transmits pixels to the frame grabber. Twopixels are received on the first pixel clock; p...

20 A modern digital frame grabber should be able to convert data from cameras witheach of these formats into scan line ordered images in system memory. Resolution The ability of a camera to resolve details in a scene is dependent on the type oflens employed and the relation of the camera to the scen...

22 • Graduations have stripes Possible Cause/Solution: • If any of the symptoms described above exist, try reversing the Pixel Clock pins.The pins which should be swapped will depend on whether the pixel clock isbeing driven by the camera (most common) or is driven by the Frame Grabber.For example, ...
