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 
SCXI-1141/1142/1143.
