Pin Assignments

Table 1 shows the pin assignments for the connectors on the IMAQ A8020 
cable.

Triggering

You can use the IMAQ A8020 cable for applications requiring precise 
triggering or exposure control. In addition to connecting the video signal 
between the camera and the IMAQ 1409 device, the IMAQ A8020 cable 
also connects the camera control lines on the IMAQ 1409 to the exposure 
and trigger inputs on the camera. The IMAQ 1409 can then be programmed 
to generate precise timing pulses for controlling the camera.

Tip

Visit the National Instruments Camera Advisor Web site at 

ni.com/camera

 for 

application notes and sample code for many of the cameras the IMAQ A8020 supports.
