Select from an NIDAQmx physical channel control programmatically

[acfkt]

Does anyone know how to select from a NIDAQmx physical channel control programmatically.  Specifically if the user has filled out an array table column with 1,3,4 for example, I want to select WLS-9163/ai0, WLS-9163/ai2, and WLS-9163/ai3 from the physical channel control, place these choices into an array and start my acquisition task with said array.

Thanks much.

You can put the desired channels in an array and use a For Loop around the Create Channels function.

Thanks Steve,

This looks close to a solution!  I can hard code the list of "Actual Device Channels", but it would be nice to programmatically acquire this list.  Maybe I don't need to use a physical channel control... but this control is finding out which device(s) and which channels are available, so I had hoped I could access it programatically.  Any further ideas?

I am modifying what used to be an acquisition system based on an ASIO sound driver and sound recording equipment.  The system will now be based on the WLS-9163.  The users are used to thinking of things in terms of channel 1,2,3 etc.  While I could modify their interface, I would rather it stayed identical for them, hence my need to map "1" to WLS-9163/ai0.

Thanks much

Terry,

This will give you an array of the Analog Input channels (AI.PhysicalChans):

And the product name (Type).

Is this what you were looking for?

Yes that would be exactly what I was looking for.  Thanks Steve.

With Terry's example, is it possible to use a function that will pass different configurations with the User's selections rather than typing them manually. 

What I really mean is: 

1: ON 

3: OFF 

0: OFF

1: OFF 

3: ON 

0: OFF

1: OFF

3: OFF

0: ON 

etc etc... 

Many Thanks
