Digital Trigger from Load Cell

[Bentup]

I am using a PCI-4472 Card with Labview 7. I have a load cell that I would like to use as a trigger for a camera that I am using. Just wondering what the best way of achieving this is? Is it possible to just use the external trigger on the DAQ card to output a voltage to my camera trigger every time the load cell signal is increased? Using a rising edge to catch the increase in voltage from the load cell?

The best way to do this is to trigger your 4472 with an analog start trigger. This will monitor your analog line until the voltage value rises above a certain value and then acquisition will begin. Then use the DAQmx Export Signal.vi to export the start trigger to one of your PFI lines. Then, externally connect this PFI line to your camera to receive this trigger.

I've attached a VI that should do this, I just added a DAQmx Export Signal.vi to one of our examples that installs with the DAQmx driver: "Cont Acq&Graph Voltage-Int Clk-Analog Start.vi"

Hope this helps!
