Connect Interface
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 standard network
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 network cable can be used to connect to the router, and the computer
is also con- nected to the router.
•
When using one crossover cable to connect PC directly, the gateway
address of the instrument should be consistent with that of the PC, and
the IP address should be at the same network segment with the PC’s IP
address.
•
When the instrument and computer are connected to the router, an
independent IP address must be assigned for the instrument.
Configure LAN Interface Information
The configurable parameters of the IT7900 series power supply are described
as follows.
LAN Config：
⚫ Mode: IP Address seting method, user can selectautomatically configure the
address of the instrument(DHCP) or manually.
⚫ IP: This value is the Internet Protocol (IP) address of the instrument. An IP
address is required for all IP and TCP/IP communications with the instru-
ment. An IP Address consists of 4 decimal numbers separated by periods.
Each decimal number ranges from 0 through 255 with no leading zeros (for
example, 169.254.2.20).
⚫ Mask: This value is used to enable the instrument to determine if a client IP
address is on the same local subnet. The same numbering notation applies
as for the IP Address. When a client IP address is on a different subnet, all
packets must be sent to the Default Gateway.
⚫ Gateway: This value is the IP Address of the default gateway that allows the
instrument to communicate with systems that are not on the local subnet, as
determined by the subnet mask setting. The same numbering notation ap-
plies as for the IP Address.
