l Auto - automatically configures the addressing of the instrument. When selected, the instrument
will first try to obtain an IP address from a DHCP server. If a DHCP server is found, the DHCP
server will assign an IP address, Subnet Mask, and Default Gateway to the instrument. If a DHCP
server is unavailable, the instrument will try to obtain an IP address using AutoIP. AutoIP auto-
matically assigns an IP address, Subnet Mask, and Default Gateway addresses on networks that
do not have a DHCP server.
l Manual - allows you to manually configure the addressing of the instrument by entering values in
the following three fields. These fields only appear when Manual is selected.
l IP Address - 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 instrument. 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).
l Subnet 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.
l DEF 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 applies as for the IP Address. A value of 0.0.0.0 indicates
that no default gateway is defined.
Dot-notation addresses ("nnn.nnn.nnn.nnn" where "nnn" is a byte value from 0 to 255) must be expressed with care, as most PC
web software interprets byte values with leading zeros as octal (base 8) numbers. For example, "192.168.020.011" is actually equi-
valent to decimal "192.168.16.9" because ".020" is interpreted as "16" expressed in octal, and ".011" as "9". To avoid confusion,
use only decimal values from 0 to 255, with no leading zeros.
