Communicate with the instrument
To communicate with the USB device, you need to use NI-VISA
TM
. VISA requires a resource string in
the following format to connect to the correct USB instrument:
USB[board]::manufacturer ID::model code::serial number[::USB interface
number][::INSTR]
This requires that you determine the parameters. You can gather this information by running a utility
that automatically detects all instruments connected to the computer.
If you installed the Keithley I/O Layer, the Keithley Configuration Panel is available from the
Microsoft

To use the Keithley Configuration Panel to determine the VISA resource string:
1. Start the Keithley Configuration Panel. The Select Operation dialog box is displayed.
2. Select Add.
