A high transmission rate support (> 115 200 bits per second) of the Camera
Link serial port is recommended to improve responsiveness of host software.
Timing
All Goldeye CL models provide the possibility to adapt the timing parameters of the
camera.
The timing of the data transfer is based on the Camera Link pixel clock frequency as
well as on enable signals defined in the Camera Link protocol. Selecting a lower
clock frequency and extending the gaps between the FVAL and LVAL enable signals
help to avoid bit errors in data transfer. Thus, it may allow to extend the usual cable
length or to use less expensive cables.
Changing the clock frequency
With each Goldeye CL camera, it is possible to select several clock frequencies, as
listed in
Changing the clock frequency also has an influence on the maximum frame rate
achievable. The following tables summarize the achievable frame rates for all
Goldeye Camera Link models.
