the IP address can then be used to communicate with the instrument. The front panel LAN indicator will come on
when the LAN port has been configured.
If you need to manually configure any instrument LAN settings, refer to Remote Interface Configuration
for information about configuring the LAN settings from the front panel of the instrument.
2. Use the Connection Expert utility of the Keysight IO Libraries Suite to add the power supply and verify a
connection. To add the instrument, you can request the Connection Expert to discover the instrument. If the
instrument cannot be found, add the instrument using its hostname or IP address.
If this does not work, refer to “Troubleshooting Guidelines” in the Keysight Technologies USB/LAN/GPIB Inter-
faces Connectivity Guide included with the Keysight IO Libraries Suite.
3. You can now use Interactive IO within the Connection Expert to communicate with your instrument, or you can
program your instrument using the various programming environments.
A private LAN is a network in which LAN-enabled instruments and computers are directly connected, and not
connected to a site LAN. They are typically small, with no centrally-managed resources. The following figure
illustrates a typical private LAN system.
1. Connect the instrument to the computer using a LAN crossover cable. Alternatively, connect the computer and
the instrument to a standalone hub or switch using regular LAN cables.
Make sure your computer is configured to obtain its address from DHCP and that NetBIOS over TCP/IP is
enabled. Note that if the computer had been connected to a site LAN, it may still retain previous network set-
tings from the site LAN. Wait one minute after disconnecting it from the site LAN before connecting it to the
private LAN. This allows Windows to sense that it is on a different network and restart the network con-
figuration.
2. The factory-shipped instrument LAN settings are configured to automatically obtain an IP address from a site
network using a DHCP server. You can leave these settings as they are. Most Keysight products and most
computers will automatically choose an IP address using auto-IP if a DHCP server is not present. Each assigns itself
an IP address from the block 169.254.nnn. Note that this may take up to one minute. The front panel LAN indicator
will come on when the LAN port has been configured.
Turning off DHCP reduces the time required to fully configure a network connection when the power supply is
turned on. To manually configure the instrument LAN settings, refer to Remote Interface Configuration for
information about configuring the LAN settings from the front panel of the instrument.
3. Use the Connection Expert utility of the Keysight IO Libraries Suite to add the power supply and verify a
connection. To add the instrument, you can request the Connection Expert to discover the instrument. If the
instrument cannot be found, add the instrument using its hostname or IP address.
