Connecting to a Site LAN
A site LAN
is a local area network in which LAN-enabled instruments
and computers are connected to the network through routers, hubs,
and/or switches. They are typically large, centrally-managed
networks with services such as DHCP and DNS servers.
1
If you have not already done so, install the Keysight IO Libraries
Suite from the Automation-Ready CD-ROM that is shipped with
your product.
2
Connect the instrument to the site LAN. Provided that your
network has a DHCP server and uses Dynamic DNS naming
service, the instrument will automatically obtain an IP address
from the network. This may take up to one minute. It will also
register its hostname with the dynamic DNS server. The default
hostname 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 are unable to communicate with the
instrument, check that a valid IP address has been assigned.
Press the front panel LAN button to view the IP address.
NOTE
Each Keysight N8700 power supply is shipped with a default hostname with the
format: A-modelnumber-serialnumber
where
modelnumber
is the instrument’s
6-character model number (e.g. N8741A), and
serialnumber
is 5th through the
9th character of the 10-character serial number located on the label on the side
of the unit (e.g. H1234 if the serial number is US24H12345). A-N8741A-H1234 is
an example of a hostname.
3
Use the Connection Expert utility of the Keysight IO Libraries
Suite to add the N8700 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, you
can add the instrument using the instrument’s hostname.
NOTE
If this does not work, refer to the chapter on “Troubleshooting Guidelines” in
the Keysight Technologies
USB/LAN/GPIB Interfaces Connectivity Guide
.

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 “Using the Web Server”
later in this chapter.
