Configuring and Establishing a LAN Connection
Connecting the instrument to a single computer (local network with no external connections)
The following addresses are recommended if there is no network administrator or if you are
responsible for configuring the settings yourself:
Example settings
DHCP OFF
Host name Set as desired (unique setting required).
IP address Computer 192.168.1.1
Logger 1 192.168.1.2
Logger 2 192.168.1.3 (assign sequentially)
↓ ↓
Subnet mask 255.255.255.0
Port number 880X
Gateway OFF
DNS OFF
Settings
Using DHCP (Dynamic Host
Configuration Protocol)
DHCP allows the instrument to automatically acquire and configure its IP
address and other settings.
When DHCP is enabled, the instrument will automatically acquire and
configure the IP address, subnet mask, and gateway if it finds an operating
DHCP server on the network.
Host name Indicates the name of the instrument on the network. Be sure that the
instrument’s hostname is not being used by any other device on the
network.
Since the instrument does not support dynamic DNS, the set hostname will
not be registered in the DNS.
IP address Indicates the address used to distinguish individual devices connected to
the network.
Be sure that the instrument’s IP address is not being used by any other
device on the network. If DHCP is enabled, the IP address will be set
automatically.
Subnet mask Divides the IP address into one part that indicates the network and another
that indicates the instrument.
Use the same setting as other devices that are connected to the same
network. If DHCP is enabled, the subnet mask will be set automatically.
Gateway
IP address
•Connecting the instrument to a network
If the computer (communications device) is connected to a different
network than the instrument, set to [ON] and specify the device that will
serve as the gateway.
If the computer is on the same network, the same setting as the default
gateway in the computer’s settings can generally be used.
•Connecting the instrument to a single computer
If connecting the instrument to the same hub, set to
[OFF]
.
If DHCP is enabled, the setting will be acquired from DHCP.
DNS
(Domain Name System)
When DNS is enabled, you can specify the device you wish to communicate
with by name instead of IP address. (IP addresses consist of a series of
numbers and are difficult to remember. Devices can be specified using
names instead of IP addresses to make the setup process more intuitive.)
If a server that can convert names to IP addresses is operating on the
network, IP addresses can be checked based on names by querying the
server. If DHCP is enabled, the setting will be acquired from DHCP.
Username and password for authentication purposes
You can impose limitations on connections when you log into the FTP of the instrument and use a
web browser of a computer.
See “FTP server connection limitations (FTP authentication)” (p. 208).
