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.

included with your device.
Step 5. Confirm That Your Device Is Recognized
The following section discusses how to confirm that your device is
recognized.
Devices Using the LabVIEW 8.5 PDA Module for Windows Mobile
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.
Using the NI-DAQmx Base Task Configuration Utility
The following sections describe how to use the NI-DAQmx Base Task
Configuration Utility.
© National Instruments Corporation 11 NI-DAQmx Base Getting Started Guide
Devices Using the LabVIEW 8.5 PDA Module for Windows Mobile
Using the NI-DAQmx Base Task Configuration Utility is required when
using devices with the LabVIEW 8.5 PDA Module for Windows Mobile.
In NI-DAQmx Base 3.0, task information is embedded in the built
application. Prior to building and downloading your VI to the PDA device,
you must configure and save the tasks you want to use.
To use the Task Configuration Utility, complete the following steps:
1. Open LabVIEW.
2. Select Tools»NI-DAQmx Base Task Configuration Utility.
Note You also can launch the Task Configuration Utility from Start»Programs»
National Instruments»NI-DAQmx Base.
NI-DAQmx Base Getting Started Guide 12 ni.com
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.
5. Each acquisition type contains a set of tabbed dialog boxes for
configuring the task. Configure all options specific to your task.
© National Instruments Corporation 13 NI-DAQmx Base Getting Started Guide
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.
NI-DAQmx Base Getting Started Guide 14 ni.com
Using Tasks in an Application
