2.3.3 1X-2YE Tap Geometry
After an image has been captured, the image is read out of the camera's imaging sensor and into
an image buffer. As pixel data is read out of the sensor and into the buffer, it is reordered so that the
pixel data for each line is in sequential ascending order from pixel 1 through the last pixel in the line.
When a camera is set for the 1X-2YE tap geometry, transmission of the pixel data from the camera's
image buffer to the frame grabber in the host PC will begin as soon as a sufficient quantity of image
data has been accumulated in the buffer.
The 1X-2YE tap geometry
is a "two tap Camera Link configuration".

Figure 6 provides a graphical illustration of how the pixel data is transmitted from the image
buffer when the 1X-2YE tap geometry is selected. The text following Figure 6 provides a word
description of how the pixel data is transmitted.
can only be used, if the camera is set for four tap sensor digitization.

The pixel clock is used to time data transmission. As shown in Figure 7 on
transmits data on each rising edge of the pixel clock. The pixel clock frequency depends on the
current setting of the camera's Camera Link Clock Speed parameter.
