Appendix B: Quick Setup and
Image Acquisition
If you are familiar with the operation of Camera Link cameras and have an understanding of imaging
fundamentals, the following steps will show you how to quickly set up this camera and begin acquiring
images.
1. On Power Up
The camera has been calibrated and configured at the factory to be ready for your evaluation when first
powered up. The default conditions are set as follows:
 System gain is set to the lowest value of 0 dB.
 Flat field calibration is always active as per the factory calibration environment. However, as this
feature is dependent on your light source and lens, flat field calibration in the customer system is
recommended for the best performance experience.
 Line rate and exposure time are set to for internal generation by the camera.
 Camera Link mode is set to mode 21, which allows operation of up to 34 KHz line rate.
2. Communicating with the Camera
 The camera is designed to interface w ith Teled yne DALSA‘s three letter command (TLC)
interface, which can be accessed using a suitable terminal program such as HyperTerminal™.
 The TLC interface is fixed to 115,200 Baud.
 Enter ‗h‘ at any time to get the list of com mand s from the camera.
 Enter the ‗gcp‘ com mand at any tim e to get the cu rrent setu p conditions of the camera.
3. Setting Up Your Optical Configuration
Typ ically, the first thing you want to d o is to evalu ate the camera‘s im age qu ality und er operating
conditions similar to those that you are likely to use in your application. In order to d o this, take the
following steps:
 The illumination, lens magnification, and focus should be set up as per you application.
 Getting the magnification right is best accomplished by setting the object-to-sensor distance. Use
the formula lens focal length x (2 + 1/magnification + magnification) to calculate this distance.
Magnification equals the sensor pixel size (7 µm) / (your object pixel size in um).
