Recently, I started an experiment using keithley 2400.
However I tried to connect keithley 2400 with computer but it doesn't work.
I use the cable rs232 to usb. rs 232 is connected keithley 2400 and usb is connected pc.
PC recognizes the keithley 2400 on COM4 but it does not work properly.
I installed NI-VISA, NI-DAQmx, Keithley configuration panel.
When I try to set up this equipment by using NI-VISA driver wizard. It recognized usb port but cannot proceeding installment with error 1073807171
How can I solve this problem?
