How Can I Control the Camera Control Lines Without External Signals?Primary Software: Driver Software>>NI-IMAQPrimary Software Version: N/A Primary Software Fixed Version: N/A Secondary Software: LabVIEW Development Systems Hardware: Image Acquisition (IMAQ)>>Digital Image Devices, Image Acquisition (IMAQ)>>Digital Image Devices>>PCIe-1429
Problem: I would like to be able to generate a pulse using the IMAQ Generate Pulse VI and route this signal out on a Camera Control (CC) line to my camera. Is this possible? I cannot find any NI-IMAQ functions to do this. If this is possible, how can I control the CC lines without bringing in an external trigger source? Solution: You cannot directly toggle the CC lines with the NI-IMAQ functions. The PCI-1426, PCIe-1429, and PCIe-1430 support routing external triggers (0-3) to the Camera Control lines (1-4). For example, External Trigger 0 can be routed to CC1, Ext Trig 1 to CC2, etc. You can configure this in Measurement & Automation Explorer (MAX) on the Camera Attributes tab under the Camera Control Lines Source section as displayed below:  You can set the CC1 line to get a signal from External TTL Trigger 0. This will allow you to control CC1 from an external source. To take this a step further, you can use the IMAQ Trigger Drive VI or the IMAQ Generate Pulse VI to drive the trigger line which in turn is routed through the CC line. This gives you control of what signal is provided to CC1 through the External TTL Trigger 0.
