error 9302 occured at NI ELVIS VPS-close.vi

[meoverhere]

I tried to make an analog to digital converter using labview and elvis.My aim was to take the rms and average values of input signal from elvis prototyping board and also to reconstruct the original signal using build waveform vi. The example vi " RC Transient.vi" is not working. It shows a broken arrow which connects vps-initialize vi to device no. Also when i try to run my vi it shows error 9302 with the message " specified refnum tyupe is invalid. For instance, you may have connected a refnum from fgen-vi to vps-vi." On this site i got the suggestion for error 9302 that I should check my device no. but that seems to be alright. Can there be any other reason for error 9302? Even when i tried to make A to D converter using fgen vi's (initialize ,close, update etc.) instead of vps vi's it shows the same error message. Please help

Thank you for contacting National Instruments.

It is very likely that the reason you are experiencing this problem is because you are using a M Series Data Acquisition board with the NI ELVIS.

There is a great KnowledgeBase article that explains why the courseware VIs won't work with your device, and offers replacement VIs that do work.
