Remote Interface Configuration 3
Configuring a LAN Interface
By default, local access network (LAN) connectivity with DHCP (Dynamic
Host Configuration Protocol) is enabled on the multimeter. DHCP
(Dynamic Host Configuration Protocol) is a protocol for automatically
assigning a dynamic IP address, subnet mask and default gateway to a
device on a network, and is typically the
easiest way to configure your
multimeter for remote communication using the LAN interface.
• Changing the DHCP setting will cause an automatic LAN restart.
• When DHCP is enabled (factory setting), the multmeter will try to
obtain an IP address from a DHCP server. If a DHCP server is found, it
will assign a dynamic IP address, Subnet Mask, and Default Gateway to
the instrument. The DHCP server may also assign the DNS address, and
may change the specified Host Name if a manually specified Host Name
is already in use.
• When DHCP is disabled or unavailable, the multimeter will use the
static IP address, Subnet Mask, and Default Gateway during power–on.
• If a DHCP LAN address is not assigned by a DHCP server, then a static
IP will be assumed after approximately 1 minute.
• If Auto–IP is enabled, a dynamic – rather than static – IP address will
be asssigned by the server at power–on.
LAN Configuration Parameters
You may choose to manually set several of the following configurable
parameters, as described in the subsections below. Following these
decriptions are procedures for setting up a LAN configuration from the
front panel and the remote interface.
•
IP Address
*
• Subnet Mask
*
• Default Gateway
*
• DNS Server
*
• Host Name
• LAN Services (Visa LAN, Sockets, Telnet, Agilent Web Server)
•
Web Password
*
These four parameters use dot
–
notation addresses. See NOTE below.
