• 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. You can also
use the Web browser on your computer to communicate with the
instrument as described under
LAN Connection without a DHCP server (Private LAN)
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.
• 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 indicate the current LAN
state (see
• Use the Connection Expert utility of the Keysight IO Libraries Suite to
add the LAN instrument and verify a connection. To add the instrument,
you can request the Connection Expert to discover the LAN instrument.
If the instrument cannot be found, add the instrument using its
hostname or IP address. You can find additional details here:
NOTE
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
settings from the site LAN. Wait one minute after disconnecting it from
the site LAN before connecting it to the private LAN. This allows the PC to
sense that it is on a different network and restart the network
configuration.
