I am tring to use the example in ke485 driver to control keithley 6487 picommeter using LabViwe 2013. the installation was O.K. and MAX detect the instrument but when I run the example no errors show but it does not take control of the keithley. The concern I have is that the driver inveroment was 2012 but I use 2013. Is this an issue. any solution or suggestions
