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.
