Hello,
I was hoping someone might be able to help me interface a Keithley 2420 with labview 2013 via RS232.
I have installed the driver details through labview, and they were successfully installed. However, when I try to run one of the examples provided (ReadSingle for example), the operation time-out and I am presented with the error message attached. This happens even if I extend the timeout period. I have checked that the Baud rate etc match on both sides.
In addition to this the Keithley occassionally flashes the error code -101, invalid character, which may or may not be related to the problem.
Has anyone else had a similar problem, and found a solution?
