Can I change Digital Input high voltage threshold?

I have a DAQmx PCIe-6259 installed in a MacPro running LabVIEW 2011 and DAQmx Base.

 

I have an instrument that I need to read digital signal from. The instrument's high voltage is measured at 0.6V, low is at 0V. I built a VI reading digital, but 0.6V high voltage signal of the instrument is read as low signal by the PCIe-6259. So whether the signal is 0V or 0.6V, the VI says signal is low/off.

 

Is there an easy was to lower the high voltage threshold for PCIe-6259 so it would read 0.6V as high?

Read the signal as an analog input and use Greater Than? comparison in software to convert to a binary signal.

Alternatively, use an amplifier to bring your voltage up to the 5V range.  A gain of 8 should work nicely.

Thanks. I think we'll go with an amplifier
