Hello,
we have the problem that we have only four analog output pins on our USB-6363-NI device for our project but need one more to control a LED lamp.
With the four analog output pins some neuronal recording devices are controlled. Now I need to activate a LED lamp (cool LED pE-100) with the NI device. This lamp needs TTL pulses to get turned on. When I plug the lamp to one of the analog output pins and send continuosly 5V through it, the camera turns on, as I want it to. When I send 0V through it, the lamp turns off. However, I can't control the camera like this because I need all four analog outputs to control my experiment. Thus, I need another way to turn on the camera with my NI device.
What I already tried:
- I plugged the lamp to PFI line and sent a digital trigger - but the lamp did not turn on (or it turned on too quick to be seen)
My question:
- is there any way, that I can use another pin on the NI board as an analog output and send 5V through it?
- could I use a trigger to turn the camera on and off instead?
- and if I can use a trigger - how can I trigger two devices separately with my NI board? I tried to make two trigger in matlab but this didn't work
