Setting Items
Authorization User Name and Password
These are used when you login to the instrument by FTP, or use a PC browser (with the
authorization setting set to on).
When authorization is enabled, login is not possible unless a correct user name and
password are entered. This setting is recommended if you wish to restrict the users who
can access the instrument.
The "Password" item is displayed as "************".
Valid characters: Alphabetic characters and symbols
If you want to allow anyone to access, or you wish to login as "anonymous" with a FTP
client, leave the user name and password fields blank.
Use DHCP


: Dynamic Host
Configuration
Protocol
DHCP is a protocol that allows devices to automatically obtain and set their
own IP addresses.
If you enable DHCP and there is a DHCP server operating in the same net-
work, the instrument's IP address, subnet mask, and gateway can be ob-
tained and set automatically.
Host Name
This is a name that identifies the instrument on the network. Assign a host
name that is different from the names of all other devices. This instrument
does not support dynamic DNS, the name that you set is not registered with
a DNS server.
IP Address
This is an address that identifies an individual device on a network.
Assign an address that is different from the addresses of all other devices.
If DHCP is enabled, the address is assigned automatically by the DHCP
server.
Subnet Mask
This is a setting used to divide an IP address shown to the network into a
network address and a host address. Use the same subnet mask for all de-
vices in the same network. If DHCP is enabled, the subnet mask is assigned
automatically by the DHCP server.
Use Gateway

IP Address
• For network connections:

When your PC (or the communicating device) is on another network than
this instrument, set this to [On] and specify the gateway device. When
the PC is on the same network, this is usually set to the same address as
the default gateway in the PC communications settings.
• When connecting the instrument to one computer:

Set to [OFF] when connecting the instrument and computer to the same
hub. When DHCP is enabled, the gateway IP address will be acquired
from the DHCP server.
DNS(Domain
Name System)
When DNS is enabled, you will be able to specify the destination device by
name rather than IP address. (IP addresses, which consist of a series of
numbers, are difficult to remember. It is easier to specify devices by name
than by IP address.)
If there is a nameserver operating on the network, it is possible to query that
server to search for an IP address based on a name. When DNS is enabled,
this information will be acquired from the DHCP server.
