start stop trigger NI-DAQ

[poli]

I am using NI-DAQ (legacy)  software to control my DAQ device 6020E(BNC). I programmed analog output to generate a constant user programmable  output  voltage , but how do i generate a start/ stop triggerat the analog output  through software control to do so? This question was asked by me in the end of the thread http://forums.ni.com/ni/board/message?board.id=250&thread.id=38941  some days back. If you are answering it here, kindly ignore the older message. Is there a way i can delete that old thread?

Hi poli,

The DAQPad-6020e’s analog outputs are software timed. There are no start and stop triggers for the analog output. When you write a voltage to the analog output it will stay that voltage until you write another one, even if you program stops. You can control when you update the output voltage in software. So your output will start when you write the first voltage to the AO channel and end when you write 0 volts to the output. If you do not write 0 volts to the output before your program ends then the output will stay at the last value you set it to. Let me know if you have any questions and have a great week.

Thanks,
