USB communications
To use the rear-panel USB connection, 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
which, once installed, allows the Microsoft
®
Windows
®
operating system to recognize the instrument.
When a USB device that implements the USBTMC or USBTMC-USB488 protocol is plugged into the
computer, the VISA driver automatically detects the device. It is important to note that only USBTMC
and USBTMC-USB488 devices are automatically recognized by the VISA driver. Other USB devices,
such as printers, scanners, and storage devices, are not recognized.
In this section, "USB instruments" refers to devices that implement the USBTMC or
USBTMC-USB488 protocol.
Connecting a computer to the Model 2450 using USB
To connect the Model 2450 to a computer, use a USB cable with a USB Type B connector on one
end and a USB type A connector on the other end (one is shipped with the instrument).
If you want to connect more than one instrument to the computer at the same time using the Model
2450 USB port, you will need one cable for each additional instrument.
To connect an instrument to a computer using USB:

2. Connect the Type B end of the cable to the instrument.
3. Turn on the instrument power. When the computer detects the new USB connection, the Found
New Hardware Wizard will start.

No
, and then click
Next
.
5. On the "USB Test and Measurement device" dialog box, click
Next
, and then click
Finish
