You were probably right, all I had to do was replace the driver with your changes and it works fine.  Thanks!

Do you understand the fundamental flaw that was in your subVI? Your intent was to not send a command unless it had changed. Because of this, when you called the subVI a second time for the other instrument with the exact same parameters, nothing at all was written. This would cause a problem with the read since you did not send the command requesting a reading.

Hey Dennis, I noticed something a little strange in that keithley driver you helped me with (which has been working like a champ, btw).

 

On the visa read function, you changed the "byte count" constant to 200 (up from 18 I think).  Is there a reason for over-shooting like that?  Just to make sure it doesn't miss something I guess?
