Verify the LAN connection on the DMM6500
Make sure that your DMM6500 is connected to the network by confirming that your instrument was
assigned an IP address.
To verify the LAN connection:
1. Press the MENU key.
2. Under System, select Communication.
3. Select the LAN tab.
A green LAN status indicator on the lower left of the LAN tab confirms that your instrument was
assigned an IP address.
Use the LXI Discovery Tool
To find the IP address of the DMM6500, use the LXI Discovery Tool, a utility that is available from the
Resources tab of the LXI Consortium website (lxistandard.org/
).
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 DMM6500
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.
