Specifying Channel Strings in NI-DAQmx
Use the channel input of DAQmx Create Channel to specify the
SCXI-1125 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)
• cold junction channel—SC1Mod1/_cjtemp
When you have a task containing SCXI-1125 channels, you can set the
properties of the channels programmatically using the DAQmx Channel
Property Node.
