Laser control via NI 6212

[ml42]

Hello,

I have a laser powered by a PRO 800 supply and a NI USB 6212 connected to my computer.

My objectif is to be able to control the laser: switch it on/off when I want.

The supply has two trigger channels (OUTPUT INPUT) that I should be able to use to achieve my goals. (or maybe I m completly wrong)

I am asbolutly new in labview so I need your help.

How should I manage such task ?

If you truly are just starting off then you should really start in the "Looking for help getting started with LabVIEW?" area that you should see on the middle right part of the screen when you look at this forum.

This forum is meant to assist people who have difficulty with LabVIEW once they get going, not to give step-by-step instructions on how to create an entirely new piece of software.  We won't write your code for you, we'll just help when you can't figure out one part of it.

You need to provide some details such as the exact make and model of the power supply, the manual, the physical connection of the supply, etc. How have you connected the 6212 to the supply?

I did not say that I want a code already done. I trained by writing a piece of code to control a rotating miror which works fine so I think I understood the very basics of Labview: I m sending the angle I want then the miror turns.

Anyway, I still don t understand the principle for triggering  (and I watched the video regarding triggering data acquisition) with labview.

Here is the device: 

 And from what I understood, the trigger input should be connected to the USB 6212 with the pin AO, the ground and the PF for the triggering ?

Why would triggered data acquisition have anything at all to do with triggering this power supply or laser? What didn't you answer my questions?

I guess you use this device:

And here you find LabVIEW drivers for the device:

Check what functionality you can get using RS232. If you can control the device via serial, just get a cheap RS232-USB cable, you do not need the NI card...
