Running the scope and AI channels at the same time. Device conflict.

[Justin.e.snodgrass]

Is there a way to run the oscilloscope and the AI channels at the same time? I'm writing a program in LabVIEW and keep getting a device conflict running them together.

[Dennis_Knutson]

What scope and AI channels? What devices are you talking about? What code are you using?

[moderator1983]

If the "Scope" that you're referring is using DAQ device as a 'resource' then that could be a reason of conflict.

You need to be elaborative.

[Justin.e.snodgrass]

The Scope that came with the ELVIS from the instrument launcher. Two channel scope using "SCOPE CH 0" and "SCOPE CH 1" as the inputs (although getting the same conflict using any of the AI channels as inputs). The program is simply using the DAQ Assistant to measure voltage from AI 2. Both the program and the scope work fine seperatly but when ran together I am getting a device conflict.

You need to refer to the manual provided with the ELVIS, it actually reserves the DAQ card, so you can't use SCOPE and DAQ channels (even if the channels are not being used by ELVIS) together.

Edited: I've used Legacy ELVIS, refer to the second last page of this manual, this talks about 'Resource Conflicts'.

[Dennis_Knutson]

I'm not at all familiar with the academic hardware but it's likely that the scope channel is just another channel on the same A/D, in which case the error is expected. As long as you only create a single task with all channels, you'll be fine.

[moderator1983]

Yeah, there are also low level functions available, you may want to use those.

[Justin.e.snodgrass]

What do you mean by "low level functions"?

[moderator1983]

With ELVIS, there is an application provided, which has softpanels for various instruments. Now, if you don't want to use the softpanel but still want to use the feature of any of the instrument and you can probably use the 'Low Level' functions... Which must be available in the 'Function Palette' (in LabVIEW), provided you've installed the driver CD/DVD included with ELVIS.

Low level functions, provides more control and option while using the instrument.

Okay, in the device conflicts list it has "Oscilloscope (NI ELVIS II and AI Channels)". So what I'm getting from this is in the program for the scope it has the two scope channels and all AI channels reserved. Does anyone know where I can get the .vi code for the ELVIS scope so I can remove the option to use the AI channels? Or possibly another DAQ scope that uses two AI channels.
