Read-Out Mode
When the TriggerMode is set to FreeRunning the frame period can be calculated for all
Read-Out Modes by adding the Extended Exposure to the frame read-out time. The
Extended Exposure value must be chosen high enough that the throughput bandwidth of
the GigE link is below 100MByte/second.
Full Resolution
In this Read-Out Mode the full resolution of the sensor is read out and streamed to the
host system. A butting gap is injected in vertical direction in the image to indicate at what
position the two separate sensors are butted to each other. The pixel value of this butting
gap is 0.
Due to the injection of the butting gap in the image the number of pixels is 2065 pixels.
However the GigE Vision interface requires a multiple of 4 pixels, for this reason the last
column (2064) is discarded.
The table below indicates the pixels in one line and where the butting gap is located (pixel
1032) and that the last pixel is discarded:

The minimum frame period of a full-resolution frame is 61 milliseconds. Note that the
minimum “Extended Exposure” setting for full resolution mode is 21000.
Binning 2x2
The detector supports 2x2 pixel binning.
The butting gap appears as the mean value of an actual pixel value and the pixel value of
the butting gap (0). The resolution in 2x2 binning mode is 1032 pixels by 774 lines.
The table below indicates the pixels in one line, and how butting gap pixel is binned:

The minimum frame period of a 2x2 binned frame is 30 milliseconds. Note that the
minimum “Extended Exposure” setting for 2x2 binned mode is 12500.
