One of the most important aspects of setting up your imaging environment 
is proper illumination. Images acquired under proper lighting conditions 
make your image processing software development easier and overall 
processing time faster. The following sections describe how to use the 
Direct Drive lighting controller and the strobe outputs of the NI Smart 
Camera to control a light.

Figure 4-1 shows the lighting connector on the NI Smart Camera.

All signals on the lighting connector are outputs from the smart camera. Do not 

connect any external voltage or current source to any pin on the lighting connector.

The NI 1722 does not offer the Direct Drive lighting controller. Do not connect to 

the LED+ and LED– connectors on the NI 1722.
