Specifying Channel Strings in NI-DAQmx
Use the channel input of
DAQmx Create Channel
to specify the
SCXI-1502 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-1502 channels, you can set the
properties of the channels programmatically using the
DAQmx Channel
Property Node
.
Text Based ADEs
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-1502.
