Configuring the NI PXI-4224 in MAX
This section describes how to create NI-DAQmx Tasks and NI-DAQmx
Global Channels in MAX that allow you to take measurements with the
NI PXI-4224.
Creating a Voltage Task or Global Channel Using NI-DAQmx
An NI-DAQmx Global Channel gives a physical channel a name and
provides scaling. An NI-DAQmx Task is a collection of channels with
timing and triggering configured. To create a new NI-DAQmx Task or
NI-DAQmx Global Channel, complete the following steps:
1. Double-click the Measurement & Automation Explorer icon on the
desktop.
2. Right-click Data Neighborhood and select Create New.
3. Select NI-DAQmx Task or NI-DAQmx Global Channel and
click Next.
4. Select Analog Input and select Voltage.
5. If you are creating a channel, you can select only one channel. If you
are creating a task, select the channels to add to the task. You can select
a range of channels by holding down the <Shift> key while selecting
the channels. You can select multiple individual channels by holding
down the <Ctrl> key while selecting channels. Click Next.
6. Enter the name of the task or channel, and click Finish.
7. Select the channel(s) you want to configure for input voltage range.
While making the selections you can select blocks of channels by
pressing the <Shift> key or individual channels by pressing the
<Ctrl> key.
8. Under the Settings tab, set the input range by entering the Min and
Max values.
9. Click the Device tab and select the Autozero mode.
10. Repeat steps 7 through 9 until you have configured all the channels.
Note For more information about how to further configure the NI PXI-4224, or how to use
LabVIEW to configure the device and take measurements, refer to Chapter 4, Theory of
Operation.
