NI-VISA Runtime
NI-VISA
TM
is National Instruments (NI
TM
) implementation of the VISA standard. There are two
versions. The full version contains diagnostic and configuration tools such as NI-Spy and NI-MAX and
the binary run-time-only files. The run-time version contains only the binary files (DLLs) that allow the
drivers to operate.
The Keithley I/O Layer (KIOL) contains a licensed version of the NI-VISA runtime.
If you already have NI software (such as LabVIEW or LabWindows) installed, you have a valid license
that can be used with Keithley drivers and application software.
If you do not have NI software installed, to use Keithley drivers or application software, you must
install the KIOL. This installs a valid, licensed copy of the NI-VISA runtime to use with Keithley drivers
or application software. KIOL installs a valid license for the NI-VISA Run-Time Engine only (not the
full version of NI-VISA).
Keithley Configuration Panel
The Keithley Configuration Panel is a configuration utility for IVI drivers, similar to NI-MAX. It can also
autodetect USBTMC instruments and LAN instruments that support the VXI-11 protocol.
Keithley Communicator
The Keithley Communicator is a dumb terminal program that uses VISA to communicate with the
instrument.
