To add another property to the property node, right-click an existing 
property and left-click Add Element. To change the new property, 
left-click it and select the property you wish to define.

Refer to the LabVIEW Help for information about property nodes and specific 

NI-DAQmx properties.

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.
