2.3.3 1X2 Tap Geometry
The characteristics of the 1X2 tap geometry are:
On each cycle of the Camera Link pixel clock, the data for two pixels are transmitted via the
Camera Link interface. This is commonly referred to as a "two tap" Camera Link configuration.
The camera will begin transmitting data from the sensor line. It will transmit the data for the first
two pixels in the line on the first Camera Link pixel clock cycle, the next two pixels in the line on
the second pixel clock cycle, the next two pixels in the line on the third clock cycle, and so on
until the line is complete.
When transmission for the line is complete, transmission for the next line acquisition will begin
after a time interval (see Fig. 10 on page 31) and will proceed in a similar fashion. Data
transmission will continue line after line until line acquisition is stopped.
When the camera is set for the 1X2 tap geometry, it uses the base Camera Link configuration.
When the camera is set for the 1X2 tap geometry, the image AOI Width parameter must be set to
a number divisible by 8.
Transmission according to the 1X2 tap geometry is shown graphically in Fig. 9 and the timing of
pixel data transmission in Fig. 10.
