I am new to this forum and to Labview. I use Labview 7.1 with DAQmx 7.5 and the Mio 6251 card.
My problem ist that I want to generate five multiple digital pulses (TTL) to trigger some devices, e.g. I have 2 cameras, flashlamp, image intensifier and an injection device. For all these devices I need triggers (TTL pulses) that should be referenced to one of the five triggers and they should be flexible in high-lowtime and initial delay. The accuracy should be 1 mys. The national instruments guys where we have bought the hardware, told me that this is possible to do.
I have to say that I wanted to do that by using one counter where all triggers (PFI channels) from the property node are referenced to that counter (see attached file). If I change specifically high-lowtimes and initial delay for each seperate PFI Channel at the property node nothing happended. Can anybody explain why. I think that must be possible cause you can choose high-lowtime and initial delay for each channel at the property node seperately. Can anybody explain what I am doing wrong?
I have attached the vi.
Thanks in advance

p.s. all what I need are five flexible TTL signals that are variable in high-time, lowtime and initial delay
5 digital output channels for ttl triggering
