I don't have LabVIEW in front of me.  Go to Help->Explain Error and then put in your error code.  What description do you get?

In Labview, the explain error shows that 

error 301743 occurred at an unidentified location

This error code is undefined. Undefined errors might occur for a number of reasons. For example, no one has provided a description for the code, or you might have wired a number that is not an error code to the error code input.

Additionally, undefined error codes might occur because the error relates to a third-party object, such as the operating system or ActiveX. For these third-party errors, you might be able to obtain a description of the error by searching the Web for the error code (301743) or for its hexadecimal representation (0x00049AAF).

First of all, your error code is negative.  That is important.

Now that I am at my desk, I can see that error code -301743 means that the device you are trying to talk to did not return an ACK.  My first thought is that you are using the wrong address.
