Specifying Channel Strings in NI-DAQmx
Use the channel input of DAQmx Create Channel to specify the
SCXI-1141/1142/1143 channels. The input control/constant has a
pull-down menu showing all available external channels. The strings take
one of the following forms:
• single device identifier/channel number—for example SC1Mod1/ch0
• multiple, noncontinuous channels—for example SC1Mod1/ch0,
SC1Mod1/ch4.
• multiple continuous channels—for example SC1Mod1/ch0:4
(channels 0 through 4)
When you have a task containing SCXI-1141/1142/1143 channels, you can
set the properties of the channels programmatically using the DAQmx
Channel Property Node.

You can use text based ADEs such as LabWindows/CVI, Measurement
Studio, Visual Basic 6, .NET, and C# to create code for using the
