2. Expand Devices and Interfaces by using the
icon. Right click on NI-DAQmx
Devices >> Create New NI-DAQmx Devices >> NI-DAQmx TEDS Carrier >>
BNC-2096. The BNC-2096 Configuration window will appear as shown below.
Select the MIO device connected to the rear of the BNC-2096 as the Controlling
Device. The LED to the right of your module should appear bright green (as
pictured below) if your sensor is connected. If the sensor is not connected, then
connect it now, and click on “Scan for TEDS” button. Then click “Ok”.

3. Expand your E Series Device using the
icon, then expand the module
connected to your TEDS sensor, and highlight the TEDS sensor marked by the
TEDS icon
by left clicking on it. Once it is highlighted, you should be able to
view your TEDS sensor’s data sheet on the right pane of the window:
4. After you have verified that your TEDS data has been imported correctly, the next
step is to create a NI-DAQmx Global Channel or Task using the channel that has
been associated with the TEDS sensor.

5. If you have created a task, you should ensure that you have all the appropriate
settings configured in your task. Specifically, check the Task Timing (you
probably want to set it to Continuous).
6. You can start taking measurements right away in MAX test panels by clicking on
the Test button in the task toolbar:

Creating Your LabVIEW Application
Now that you have configured your measurement hardware, TEDS channels, and NIDAQmx measurement task, you are now ready to write your measurement application
using LabVIEW 7.1 and the NI-DAQmx 7.2 Application Programming Interface. This
can be done by auto-generating code.
1. Open LabVIEW 7.1. Select New >> Blank VI
