2.6.2 LAN Interface
When the user connect PC through LAN interface, the following is required to
use the LAN interface. The LAN interface complies with the LXI standard.
LAN Connection
Use the following steps to quickly connect your instrument to your LAN and con-
figure it. Two typical LAN interface systems are described below: private LAN
and site LAN.
• Connect to the private LAN
A private LAN is a network in which LAN-enabled instruments and com-
puters are directly connected. They are typically small, with no centrally
managed resources. When connected to a computer, a crossover cable can
be used to connect directly to the computer via the LAN interface.
• Connect to the 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. When connected to a computer, a direct
attached network cable can be used to connect to the router, and the com-
puter is also connected to the router.
