ReadSingleSample() does not work when ni box is connected via lan to usb

[schlaug]

Hey there!

I have my NI Box connected to my PC via a LAN to USB box from silex.

Now I am trying to read out the analog channels with the method ReadSingleSample from the AnalogMultiChannelReader class.

This call never returns I call the method inside of a task which has an endless timeout.

Is this a known issue? Is there any workarround?

I use the C# API

Thank you very much

NI box?

What is that?

Hi Phil,

I would have the same question: What kind of NI hardware are you using?

It is always helpful if you provide us with a bigger portion of the source code or even the project as a attachment.

Best regards,

Christoph

Hey

Here is my configuration:

I use the NI Box USB6009 OEM which is connected with a Lan to USB box from silex (SX-3000GB) to the PC.

My Code is very simple no big deal I thought

AnalogMultiChannelReader reader = new AnalogMultiChannelReader(analogRead.Stream);
analogRead.Control(TaskAction.Verify);
double[] data = reader.ReadSingleSample(); // TODO: This read is not working via lanToUSB

 analogRead is an instance of the class NationalInstruments.DAQmx.Task

And the application does not return from the last call reader.ReadSingleSample()

I hope that helps you to understand my problem

Thanks

Phil

Have you verified that this set-up works?

Are you able to makethe readings using NI-MAX?

Sounds like you may have a problem with your LAN to USB adapter.
