I am trying to run an example code, provided by the manufacturer with a Keithley 2420 3A SourceMeter. It is powered on, and set up for 488.1 GPIB Protocol. It is hooked up to my computer using a KUSB-488A GPIB cable. On the front panel of the example program, there is a drop-down menu labeled "VISA resource name." The two options available to me are LPT1 and COM1, but I don't think either of these are the right resource name. Does anybody know what VISA resource name I should be using with the Keithley, or how I can find this out? If it helps, I provided the example program I am using. Thanks in advance!

Start by opening NI-MAX and see what ports are recognized under 'devices and interfaces'.

Typically, only NI hardware is going to be recognized in MAX and you would not get any VISA resources for non-NI controllers. If there is a VISA driver for the Keithley, you can try installing that as a secondary VISA driver and enable Tulip support in MAX. Keithley support is the best place to ask about installing their hardware for LabVIEW.

If you read the intructions that come with the Keithley USB-GPIB converter they enclude installation instructions to install the National Instruments compatable version of their driver.
Yup, just read and follow the set-up instructions.

I figured it out, I realized I need a driver for both the instrument AND the connecting cable. Who woulda thought?
