Overview  
National Instruments measurement devices are packaged with NI-DAQmx  
or NI-DAQmx Base driver software. NI-DAQmx includes an extensive  
library of VIs and ANSI C functions that you can call from your application  
software, such as LabVIEW or NI LabWindows/CVI, to program all the  
features of your NI measurement devices. The NI-DAQmx Base driver  
software has an application programming interface (API), which is a  
library of VIs and ANSI C functions for creating applications for your  
device.

Step 2. For Devices Using the LabVIEW 8.5 PDA Module  
for Windows Mobile Only—Run the PDA Setup Utility  
After running the NI-DAQmx Base installation, you must copy the driver  
files to the PDA device. Complete the following steps to run the Pocket PC  
Driver Installation utility.  
1. Select Start»Programs»National Instruments»NI-DAQmx Base»  
Utilities.  
2. Click Windows Mobile-CE Driver Installation. Clicking Windows  
Mobile-CE Driver Installation launches the Pocket PC Add/Remove  
Programs utility window.  
3. Click Yes in the Pocket PC Add/Remove Programs utility window to  
install the device driver into the default application install directory.  
4. Check the PDA device screen to see if any additional steps are  
requested, such as replacing an older driver.  
If there are no error messages, you have successfully completed the steps  
to install the driver files on the PDA device.  
Step 3. Unpack the Devices, Accessories, and Cables  
Your device ships in an antistatic package to prevent electrostatic discharge  
(ESD) damage to the device. ESD can damage several components on  
the device.  
Caution Never touch the exposed pins of connectors.  
To avoid such damage, take the following precautions:  
Ground yourself using a grounding strap or by touching a grounded  
object.  
Touch the antistatic package to a metal part of the computer chassis  
before removing the device from the package.  
Remove the device from the package and inspect the device for loose  
components or any sign of damage. Notify NI if the device appears  
damaged in any way. Do not install a damaged device in the computer,  
PDA device, or PXI chassis.  
Store the device in the antistatic package when the device is not in use.  
For safety and compliance information, refer to the device documentation  
packaged with your device.

Accessories and PCI/PXI Devices  
Install accessories and/or terminal blocks according to the instructions in  
their user guides. Install PCI and PXI devices according to the instructions  
included with your device.  
Step 5. Confirm That Your Device Is Recognized  
The following section discusses how to confirm that your device is  
recognized.  
Windows Mobile devices only indicate whether a hardware installation  
error occurred. If there are no error messages, you have successfully  
installed the features and the device is recognized by the NI-DAQmx Base  
driver. If you receive an Unknown Device error message, you have not  
correctly installed NI-DAQmx Base on the PDA device. Refer to Step 1.  
Install the NI-DAQmx Base Software for more information about how to  
install the PDA features of the NI-DAQmx Base driver.  
Step 6. Create and Configure Tasks  
A task, an important concept for NI-DAQmx and NI-DAQmx Base, is  
a collection of one or more channels with timing, triggering, and other  
properties. Conceptually, a task represents a measurement or generation  
you want to perform. You can set up and save all configuration information  
in a task and use the task in an application.

Create, Modify, and Configure a Task in  
NI-DAQmx Base  
Create a new task or modify an existing task in the Task Configuration  
Utility task list. The pre-installed tasks are configured to work with the  
examples without modifications. To modify an existing task, select it in  
the task list. To create a new task, complete the following steps:  
1. Click Create New Task. The Create New Task.vi window opens.  
2. Enter a name for the new task.  
3. Select the device. For devices using the LabVIEW 8.5 PDA Module  
for Windows Mobile, select the device that matches your installed  
hardware.  
4. Select the acquisition type. Click OK when finished.

Tip You can view context help for the Task Configuration Utility by pressing <Ctrl-H>.  
6. Click Save & Exit when you are finished configuring your tasks.  
The task configuration is automatically saved into LabVIEW global  
variables. You do not need to explicitly save the configuration.  
To transfer the task configuration to other computers, click Export  
Configuration and save the tasks to a file. You then can use Import  
Configuration to import the task configuration.  
Note The Import Configuration and Export Configuration options operate on the entire set  
of tasks shown in the Task Configuration Utility. Importing a configuration replaces any  
existing tasks, including the predefined tasks for the example programs.  
Devices Using the LabVIEW 8.5 PDA Module for Windows Mobile  
When you are using devices that use the LabVIEW 8.5 PDA Module for  
Windows Mobile, the task configuration is built into the target application.  
You cannot retrieve the task information after it is embedded in a built  
application. Exporting the configuration allows you to preserve the task in  
case of accidental deletion when using the Task Configuration Utility.
