Data Translations communication problem

[Pella1]

I'm working with a Data Translation DT9800 and the analog voltage that I'm looking at seems to be outputting a voltage of 190 when the maximum voltage should be 3  volts.  I just recently switched to a different, newer computer with the same VI and it is giving me these problems. We've tried a combination of restarting the computer and box and when we hook it up to the computer but haven't gotten consistent results. We did get it working once after plenty of messing around with it and it didn't seem that it was any one thing that made it work. When we were getting the high readings we checked the voltage coming from the channel we were looking at and it seemed to be acting like normal and definitely not putting out 190 volts. The control for the output signals were all good while this was happening.

I'm not sure if this is a box specific problem or if anybody else has seen something like what I'm describing with another box. Even if you haven't, any suggestions on what to look for to get this working?

The board you mentioned, is rated for maximum analog output of +/- 10V. And the board is USB powered? I sounds impossible to me that you are getting 190 volts. (you are getting more voltage than you are supplying) If you are getting that high voltage, it is Most Definitely a hardware problem. Also, your post is little confusing. Are you having this problem for analog output, or Input? How are you measuring the voltage? Did you try contacting manufacturars?

Sorry, it was the input to the computer. The meter on the leads showed that it was putting out 2.5V and a probe in the VI showed 190V. But not matter, found out the issue was we were running on a USB3.0 instead of 2.0 and it didn't like that.

Thanks for your help though.
