Reviewing LAN trigger events in the event log
The event log records all LXI events generated and received by the instrument. You can view the
event log using any command interface or the embedded web interface. The following information
shows in the log:
• The LXI event log displays the event identifier, timestamp, and text of the event log message.
• The EventID column shows the event identifier that generated the event.
• The System Timestamp column displays the seconds and nanoseconds when the event
occurred.
• The Data column displays the text of the event message.
LAN troubleshooting suggestions
If you are unable to connect to the instrument's web interface, check the following items:
• Verify that the network cable is in the LAN port on the rear panel of the instrument, not one of the
TSP-Link
®
ports (see the description in Rear panel overview (on page 2-7)).
• Verify that the network cable is in the correct port on the computer. The LAN port of a laptop may
be disabled when the laptop is in a docking station.
• Verify that the configuration information for the correct ethernet card was used during the setup
procedure.
• Verify that the network card of the computer is enabled.
• Verify that the IP address of the instrument is compatible with the IP address on the computer.
• Verify that the subnet mask address of the instrument is the same as the subnet mask address of
the computer.
• Restart your computer.
• Turn the instrument's power off, and then on. Wait at least 60 seconds for the network
configuration to be completed. Verify that the correct settings are assigned to the instrument:
1. Press the MENU key.
2. Under System, select Communication.
3. Select the LAN tab.
4. Verify the settings.
If the above actions do not correct the problem, contact your system administrator.
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 (on page 2-65
) 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.
