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.
