3 Remote Interface Configuration
Configuring LAN Parameters
DHCP
DHCP 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 assigned by
the server at power–on.
Auto–IP
The Auto–IP standard automatically assigns an IP address to the multimeter when on a
network that does not have DHCP servers.
• Changing the Auto–IP setting will cause an automatic LAN reset.
• Auto–IP allocates IP addresses from the link– local address range (169.254.xxx.xxx).
• From the factory, the Auto–IP setting is enabled.
• The IP address is stored in non–volatile memory, and does not change when power
has been off, after a Factory Reset (*RST) command, or after an Instrument Preset
(SYSTem:PRESet) command.
IP Address
An Internet Protocol (IP) Address is required for all IP and TCP/IP communications
with the instrument. If DHCP is enabled (factory setting), the specified static IP address
is not used. However, if the DHCP server fails to assign a valid IP address, or if DHCP
and Auto–IP are both off, the currently configured static IP address will be used.
• Changing the IP address will cause an automatic LAN reset.
