Lan Connections - Site And Private - Agilent Technologies N8900 series Operating Manual

2. With the Connection Expert utility of the Agilent IO Libraries Suite running, the computer will automatically recog-
nize the instrument. This may take several seconds. When the instrument is recognized, your computer will display the
VISA alias, IDN string, and VISA address. This information is located in the USB folder.
3. You can now use Interactive IO within the Connection Expert to communicate with your instrument, or you can pro-
gram your instrument using the various programming environments.

LAN Connections - site and private

Equipment DamageNever insert a network cable which is connected to Ethernet or its com-
ponents into the master- slave socket on the back side of the unit.
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. The following figure illustrates a typical site LAN system.
A private LAN is a network in which LAN-enabled instruments and computers are directly connected, and not con-
nected 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 site LAN or to your computer using a LAN cable. The as-shipped instrument LAN set-
tings are configured to automatically obtain an IP address from the network using a DHCP server (DHCP is set On). The
DHCP server will register the instrument's hostname with the dynamic DNS server. The hostname as well as the IP
address can then be used to communicate with the instrument. If you are using a private LAN, you can leave all LAN
settings as they are. Most Agilent 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. The front panel Lan indic-
ator will come on when the LAN port has been configured.
2. Use the Connection Expert utility of the Agilent IO Libraries Suite to add the Agilent N8900 models and verify a con-
nection. To add the instrument, you can request the Connection Expert to discover the instrument. If the instrument
cannot be found, add the instrument using the instrument's hostname or IP address.
3. You can now use Interactive IO within the Connection Expert to communicate with your instrument, or you can pro-
gram your instrument using the various programming environments. You can also use the Web browser on your com-
puter to communicate with the instrument as described under
