USB communications
To use the rear-panel USB port, you must have the Virtual Instrument Software Architecture (VISA)
layer on the host computer. See "How to install the Keithley I/O Layer" in the
Model 2450 Reference
Manual
for more information.
VISA contains a USB class driver for the USB Test and Measurement Class (USBTMC) protocol that,
once installed, allows the Microsoft
®
Windows
®
operating system to recognize the instrument.
When you connect a USB device that implements the USBTMC or USBTMC-USB488 protocol to the
computer, the VISA driver automatically detects the device. Note that the VISA driver only
automatically recognizes USBTMC and USBTMC-USB488 devices. It does not recognize other USB
devices, such as printers, scanners, and storage devices.
In this section, "USB instruments" refers to devices that implement the USBTMC or
USBTMC-USB488 protocol.
