    <Note: Choosing the appropriate Camera Link cable length > According to the Camera Link Specification, the maximum cable length is 10 m. But the maximum cable length to be able to transfer data depends on the type of cable performance and clock speed. The actual maximum transmission distance becomes less than 10 m at faster clock speeds, though the transmission distance of 10 m is feasible at slower clock speeds.

  • Page 21: Camera Control

    4 Camera Control The camera can be controlled through serial communication. Two methods can be used to change the camera’s parameters. The first approach is to change parameters using NCCtrl (Camera control software). Or you can also change the parameters directly from your application by using binary read/write commands to set values in the camera register.

  • Page 37: Setting Gain

    4.10 Setting Gain It is possible to adjust the gain setting of this camera (x1 ~ 6). This is done by adjusting the slope of the line in the figure below. The slope becomes steeper when you raise the gain, and saturation occurs at a lower light exposure level. On the other hand, at a lower light level, the output increases, so the sensitivity is said to have increased.

  • Page 39: Pixel Correction

    4.12 Pixel Correction Generally speaking, image sensors (CCD, CMOS and so on) have fixed pattern noise and photo response non-uniformity. When you use a lens, lens shadings and light sources also can cause non-uniformity. The camera is factory set to the optimal correction before shipping in order to provide images of high grade.
