Overview of the Communication Functions

• Communication Timeout

This function drops the connection with the PC if there is no data transmission for a
given time at the application level (see “Functional Construction”). For example, this
function prevents a PC from being connected to the recorder indefinitely which would
prohibit other users from making new connections for data transfer.

<Related Topics>

• Communication timeout setting: Section 2.6

• Keepalive

This function drops the connection if there is no response to the inspection packet that
is periodically transmitted at the TCP level.

Using the Ethernet Interface (/C7 Option)

Explanation

For details on the settings, consult your system or network administrator.

• Host Name

Set the recorder’s host name and the domain name of the network to which the
recorder belongs. Be sure to set these items when using the DNS.

• Host

Set the recorder’s host name using up to 64 alphanumeric characters.

• Domain

Set the network domain name to which the recorder belongs using up to 64
alphanumeric characters.

• IP Address, Subnet Mask, and Default Gateway

• IP address

• Set the IP address to assign to the recorder. The default value is 0.0.0.0.

• The IP address is used to distinguish between the various devices connected to
the Internet when communicating using the TCP/IP protocol. The address is a
32-bit value normally expressed with four values (0 to 255), each separated by a
period as in 192.168.111.24.

• M (Subnet Mask)

• Specify the mask that is used to determine the network address from the IP
address. The default value is 0.0.0.0.

• Set this value according to the system or the network to which the recorder
belongs. In some cases, this setting may not be necessary.

* When the key, key, or key is pressed while holding down the SHIFT key,
the operation is reversed as when the respective key is pressed by itself.

CHARACTER

2.3 Configuring the Ethernet Interface

• G (Default Gateway)

• Set the IP address of the gateway (router, etc.) used to communicate with other
networks. The default value is 0.0.0.0.

• Set this value according to the system or the network to which the recorder
belongs. In some cases, this setting may not be necessary.

• Setting the DNS (Domain Name System)

The DNS is a system that correlates the host name/domain name to the IP address.
The host name/domain name can be used instead of the IP address when accessing
the network. The DNS server manages the database that contains the host name/
domain name and IP address correlation.

• On/Off

Select On when using the DNS.

• P (Primary DNS Server)

Set the IP address of the primary DNS server. The default value is 0.0.0.0.

• S (Secondary DNS Server)

Set the IP address of the secondary DNS server. The default value is 0.0.0.0. If
the primary DNS server is down, the secondary server is used to search the host
name and IP address correlation.

• Suffix_P (Primary Domain Suffix), Suffix_S (Secondary Domain Suffix)

When the recorder searches another server using the DNS server, the domain
name of the recorder is appended to the host name as a possible domain name if it
is omitted. If the IP address corresponding to the server name is not found on the
DNS server, then it may be that the system is configured to use another domain
name for searching. This alternate domain name is specified as the domain suffix.

• Set the domain suffix using up to 64 alphanumeric characters.

• Up to two domain suffixes can be specified (primary and secondary).

• Saving the Settings

To activate the settings made in the Basic Setting mode, the settings must be saved.

You can limit the users that can access the Setting/Measurement and Maintenance/Test
servers on the recorder via the Ethernet interface.

• Enabling/Disabling the Login Function

Set whether to use the login function.

• Registering Users

• User level

Select either of the user levels, administrator or user.

• Administrator

One administrator can be registered. An administrator has the authority to use all
Setting/Measurement server and Maintenance/Test server commands.

• User

Six users can be registered. A user has limited authority to use the commands.
See section 4.2.

• Selecting Whether to Register (On/Off) the User

If On is selected, set the user name and password.

• Setting the User Name

• Set the user name using up to 16 alphanumeric characters.

• The same user name can not be registered.

Note

• The relationship between the login function and the user name that is used when accessing

the recorder is as follows:

• The registered user name and password can be used to login to the recorder.

• The user level is the level that was specified when the user name was registered.

• When the login function is set to “Not”

• The user name “admin” can be used to login to the recorder as an administrator.

Password is not necessary.

• The user name “user” can be used to access the recorder as a user. Password is not

necessary.

• There are limitations on the number of simultaneous connections or simultaneous uses of the

recorder from the PC (see section 2.1).

• For a description of the login process of the Setting/Measurement server and Maintenance/
