LXI LAN status indicator

Most LAN network interface cards have two LEDs, one that indicates LAN traffic and one that
designates the LAN speed (10 MBits, 100 MBits, 1 GBits) through the color of the LED. LXI goes one
level higher than this and states that all LXI compliant devices need a LAN status indicator. This can
be an LED or an indicator on a display. It shows if the instrument has a valid IP address or is in a fault
state.
When diagnosing a LAN connection issue with an LXI instrument, see if the LAN status indicator is
signaling a valid or fault condition. If there is an error, you cannot communicate with the instrument
through the LAN connection. In this case, you need to check the LAN parameter settings from the
front panel of the instrument. Make sure if you change a LAN setting through the front panel that you
select the "Apply LAN Settings" for the changes to take affect.

Initialize the LAN configuration

The LXI specification mandates that all LXI conformant instruments need a LAN reset mechanism.
This can be a recessed switch or a menu option on the front panel that will put all the LAN settings
back to known defaults. If you cannot communicate with your instrument, perform this reset.
The instrument is returned to DHCP and Auto-IP enabled. If you set your computer to match, you
should be able to use a discovery tool to determine the IP address and communicate with the
instrument again. Also check the LAN status indicator to verify that there are no faults.
To reset the Model 707B or 708B, from the front panel, select MENU, then select LAN > RESET.

Install LXI Discovery Browser software on your computer

You can use the LXI Discovery Browser to identify the IP addresses of LXI certified instruments that
are set up for automatic IP address selection. Once identified, you can double-click the IP address in
the LXI Discovery Browser to open the web interface for the instrument.
The LXI Discovery Browser is available on the instrument CD. It is also available on the
website (http://www.keithley.com).
To locate the LXI Discovery Browser on the website:
1. Select the Support tab.
2. In the model number box, type 707B or 708B.
3. From the list, select Software. A list of software applications for the Model 707B or 708B is
displayed.
4. See the readme file included with the application for more information.
