Chapter 5 Using the SCXI-1503© National Instruments Corporation 5-11 SCXI-1503 User ManualNote Refer to the LabVIEW Help for information about property nodes and specificNI-DAQmx properties.Specifying Channel Strings in NI-DAQmxUse the channel input of DAQmx Create Channel to specify theSCXI-1503 channels. The input control/constant has a pull-down menushowing all available external channels. The strings take one of thefollowing forms:• single device identifier/channel number—for example SC1Mod1/ai0• multiple, noncontinuous channels—for example SC1Mod1/ai0,SC1Mod1/ai4.• multiple continuous channels—for example SC1Mod1/ai0:4(channels 0 through 4)When you have a task containing SCXI-1503 channels, you can set theproperties of the channels programmatically using the DAQmx ChannelProperty Node.Text Based ADEsYou can use text based ADEs such as LabWindows/CVI, MeasurementStudio, Visual Basic 6, .NET, and C# to create code for using theSCXI-1503.LabWindows/CVILabWindows/CVI works with the DAQ Assistant in MAX to generatecode for an voltage measurement task. You can then use the appropriatefunction call to modify the task. To create a configurable channel or task inLabWindows/CVI, complete the following steps:1. Launch LabWindows/CVI.2. Open a new or existing project.3. From the menu bar, select Tools»Create/Edit DAQmx Tasks.4. Choose Create New Task In MAX or Create New Task In Projectto load the DAQ Assistant.5. The DAQ Assistant creates the code for the task based on theparameters you define in MAX and the device defaults. To changea property of the channel programmatically, use theDAQmxSetChanAttribute function.
