Appendix C: 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 color 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 one.



Flat field calibration is

not

active as this feature is dependent on your light source

and lens.



Line rate and exposure time are set to for internal generation by the camera.



White balance is neutralized (diagonal matrix).



Camera Link mode is set to the standard RGB medium mode which allows operation
of up to 20 KHz line rate. The camera will run at up to a 33 KHz line rate using
Camera Link Deca mode, but it may be easier to start your evaluation using the
medium mode. Set your Camera Link frame grabber up to receive the standard RGB
medium mode.

2. Communicating with the Camera



The color camera is designed to power up with a GenICam-compliant interface.



CamExpert provides an easy-to-use GUI that can be used to set up and evaluate the
camera.



The camera also comes with Teledyne DALSA’s three letter command (TLC) interface
option, which can be accessed using a suitable terminal program such as
HyperTerminal™.



If you want to use the TLC interface, wait for the LED indicator on the camera turns
green. Note that the camera defaults to 9.6 KBaud when first powered up.



Enter ‘h’ at any time to get the list of commands from the camera.



Enter the ‘gcp’ command at any time to get the current setup conditions of the
camera.

3. Setting Up Your Optical Configuration

Typically, the first thing you want to do is to evaluate the camera’s image quality under
operating conditions similar to those that you are likely to use in your application. In order
to do this, take the following steps:
