I cannot display data from multiple pressure sensors my NI 9219 through Labview

[Lee A Wilson]

I am attempting to display data from two pressure sensors for a wind tunnel.

I have a NI 9219 data acquisition system.  I had the system working before upgrading to labview 2009.  but i don't know how it was originally set up.  

How do I get labview to communicate with the DAQ system?

it has something to do with the Daq MX software, but have never used it before.

Lee,

You will need to install the DAQmx drivers from ni.com/drivers.

The newest version for windows machines is http://joule.ni.com/nidu/cds/view/p/id/2337/lang/en

I reinstalled the DAQmx drivers and it seemsd to be working. however I am having another problem,

I am attempting to get data from two pressure sensors and a thermocouple. 

When i attempt to aquire data, I can plot the data and it looks ok, but I cannot read out the data, or manipulate it.  I need to seperate the values and do some math and then store the result.  how do I do this?

thanks a bunch!

Lee,

Take a look at some of the DAQmx examples in LabVIEW.  There are some great resources that should give you a jump start on the appropriate way to manipulate data for a DAQmx task.

You can find these examples by going to LabVIEW Help » Find Examples » Hardware Input and Output » DAQmx » Analog Measurements.
