How Can I Control the Camera Control Lines Without External Signals?

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 MAX on the Camera Attributes tab under the Camera Control Lines Source section (see KB linked below). You can set the CC1 line to get a signal from External TTL Trigger 0. You can now 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 TTL0. The output on the external trigger is then routed back to the input on the board. So this in a sense gives you effective control of what gets sent out on CC1, via TTL_IN(0), and via TTL_OUT(0).
