Error 50103 by using 9229 to collect data

[alex.]

I use 9229(usb casing) to collect data by attached vi.

But got error 9229 as attached, any suggestion?

Hi Turbot,

Thanks for the post and I hope your well today. 

It is generally good programming practice to only have one AI/AO DAQ task. I would use one task, and use ai1:3 and see if you still get an error or not.

Hope this helps,

May I know how to use ai1:3, thanks.

You use it just like that. Instead of Dev1/ai0, use Dev1/ai0:3. Simple.

You can do the same thing by clicking the little arrow on the right side of the physical channel constant and selecting Browse. Use Ctrl-Click or Shift-Click to select your channels.

This is probably covered in the Getting Started with DAQmx tutorials.

I tried to click on it , but still can only select one channel as screenshot, any suggestoin?

Did you not read the part where I said to select 'Browse'?

[alex.]

Yes, I use the browse and get 4 input as the screenshot as http://forums.ni.com/ni/attachments/ni/250/45494/2/shot.JPG

But when running it, got error 50103 said cannot run at same time.

Thanks, I have used shift key and done it.
