Press the cursor keys to select ON or Auto.
If you selected ON, you must enter information according to “Entering the Domain

If you selected Auto, the DHCP automatically sets the entry information from
“Entering the Domain Name” to “Entering the Secondary Domain Suffix.”
Therefore, you do not have to enter the information.
Restarting this instrument
After you set the TCP/IP parameters for the first time or change the parameters,
restart this instrument to apply the new settings.
Explanation
To use the Ethernet communication functions of this instrument, the DHCP, IP address,
IP address, subnet mask, default gateway, and DNS must be specified.
Consult your system or network administrator when setting these parameters.
• DHCP (Dynamic Host Configuration Protocol)
DHCP is a protocol that allocates settings that are needed temporarily to PCs
connecting to the network. If DHCP is turned ON when a DHCP server exists on the
network, the parameters below are automatically assigned to PCs and other devices
connected to the network.
IP address
Subnet mask
Default gateway
Broadcast
DNS
• To use DHCP, the network must have a DHCP server. Consult your network
administrator to see if DHCP can be used.
• If DHCP is switched from OFF to ON, it may take several tens of seconds before
the IP address can be retrieved.
• When DHCP is turned ON, different settings may be assigned each time the power
is turned ON. When accessing this instrument from a PC using the FTP server
function (see section 5.6), you must check this instrument TCP/IP settings such as
the IP address each time the power is turned ON.
