Pin Assignments
Table 1 shows the pin assignments for the connectors on the IMAQ A8055
cable.
Triggering
You can use the IMAQ A8055 cable for applications requiring precise
triggering or exposure control. In addition to connecting the video signal
between the camera and the IMAQ 1409/1410 device, the IMAQ A8055
cable also connects the camera control lines on the IMAQ 1409/1410 to the
exposure and trigger inputs on the camera. The IMAQ 1409/1410 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 the Sony XC-55.
