I have two applications that I am playing with just trying to learn some DAQ functionality with LabVIEW and MS for VB.NET. They both input and output the same signals. I am reading in a clock signal generated from one of the counters on my MIO card with ai1 (differential). I have two thermocouples attached to an SCXI-1125 on channels Mod1/ai1:0. Before I added the clock signal, LabVIEW read the correct values. After, one of the thermocouple readings went nuts. I then ran the VB program and the thermocouple readings were fine (though the clock signal either isn't being generated or isn't being read). I have included two screen shots so you guys can see what I am talking about. My question regards the thermocouple reading. Why is it fine in MAX and VB, but crazy in LabVIEW even though all I did was add a clock signal?

Hello-

You will need to use the Device.Reset() method. You first need a reference to the device that will be returned by DaqSystem.LoadDevice("").

Thanks-

This works:

Private dvc As DAQmx.Device

dvc = DaqSystem.Local.LoadDevice("SC1Mod1")

dvc.Reset()
