aiterminalconfiguration question

[andy_kennaugh]

When specifying the AITerminalConfiguration I see it in the examples as (AITerminalConfiguration)(-1) or CType(-1,AiTerminalConfiguration)

What does the -1 mean when the enums are

Nrse = 10078,
Rse = 10083,
Differential = 10106,
Pseudodifferential = 12529?

Thanks

Andy

Hi,

-1 is the default value that is set at run time, NI-DAQmx chooses the default terminal configuration for the channel. The default is that which you may have set in MAX (measurement and automation explorer). You may be able to use a property node to programatically obtain what the default might be?

I hope this helps!

Kind Regards

Kurt
