simple activex problem

[kyle123]

I am getting an error message when I try to use the activex software in Labview 8.5 to recieve data from an MTi inertial sensor. It is an Error - 2147467259, unspecified. All I am doing is opening the reference, reading data, and closing it but it does not seem to work. The error seems to occur at the close block but I do not get any data out as well. Any suggestions?

I'm not quite sure I understand what you are saying. I&nbsp;have a property node immediately following the open reference block but it still gives an error.

Did you check the example vi in that link?

[kyle123]

yeah, although I'm not sure if this applies to my vi. Should I delete the open and close reference blocks? are they needed?

You shouldn't have to delete the open and close reference blocks (they should be required in this case, I believe). I had a look at the example and the picture you supplied. I believe you need something like the property node in the attached picture immediately following your open reference.<img src="Loading Image..."> Message Edited by corys on 08-05-2008 08:17 AM

ok so I tried putting a property node to get the ID but it gives me the same error. would this problem have something to do with the communication between the pc and sensor?

I think I got it, I can read some data now. It was just an initialization problem with the sensor. Thanks for the help

Even I thought i the problem might point to the sensor .As corys had suggested,It shld have solved the issue if it is with respect to Property node.

From the website of XSENS (the MTi's manufacturer): Specifically thier FAQs... <a name="1.3" target="_blank">1.3 Q: Where can I get sample source code and more
detailed information about the API (application program interface) of
the software development kit?</a> A: Please contact Xsens (<a href="mailto:***@xsens.com" target="_blank">***@xsens.com</a>)
and we will send you a copy of the Software Development Kit
Documentation, containing details on the MotionTracker object
interfaces, the MT Communication C++ class (sources included), example
source code (C/C++, Matlab, LabVIEW, Excel) including tested code for
Linux, etc.
