National Instruments SCXI -1125 用户手册

You can use text based ADEs such as LabWindows/CVI, Measurement 
Studio, Visual Basic, .NET, and C# to create code for using the 
SCXI-1125.

LabWindows/CVI works with the DAQ Assistant in MAX to generate 
code for a task. You can then use the appropriate function call to modify 
the task. To create a configurable channel or task in LabWindows/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 Project 
to load the DAQ Assistant.

5.

Configure the NI-DAQmx task following the instructions in the 

 section.

6.

The DAQ Assistant creates the code for the task based on the 
parameters you define in MAX and the device defaults. To change 
a property of the channel programmatically, use the 

DAQmxSetChanAttribute

 function.

Refer to the NI LabWindows/CVI Help for more information on creating NI-DAQmx 

tasks in LabWindows/CVI and NI-DAQmx property information.

When creating a task in Visual Basic .NET and C#, follow the general 
programming flow in Figure 5-1. You can then use the appropriate function 
calls to modify the task. This example creates a new task and configures an 
NI-DAQmx channel on the SCXI-112511251125. You can use the same 
functions for Visual Basic .NET and C#.

All of the different ADEs that configure the SCXI-1125 access an 
underlying set of NI-DAQmx properties. Table 5-5 provides a list of some 
of the properties that configure the SCXI-1125. You can use this list to 
determine what kind of properties you need to set to configure the device 
for your application. For a complete list of NI-DAQmx properties, refer to 
your ADE help file.
