ment and a PC

Accessing files on the instrument via

FTP (p.327)

The instrument is equipped with an FTP (File

Transfer Protocol, compliant with RFC959) serv-

er. You can use a PC FTP client to transfer files to

instrument media and perform other file opera-

tions.

Controlling the instrument by command

communications (p.332)

You can control the instrument by creating pro-

grams and connecting to the command communi-

cations port by TCP.

For more information about commands, refer to

the communications operation manual on the sup-

plied application disk.

15.1 LAN Settings and Connection (Before Using FTP/Internet Browser/Command Communications)

314

The required settings are different, depending on whether the instrument is to be connected to an

existing network or directly to a PC.

The required settings are different, depending on whether the instrument is to be

connected to an existing network or whether a new network consisting only of

the instrument and one computer is to be configured.

The following items must be assigned in advance by your network administrator.

Be sure that there is no conflict with other devices.

(Using as Local Network Without External Connections)

If there is not administrator for your network, or if you have been entrusted with

settings, the following addresses are recommended.

15.1 LAN Settings and Connection (Before Using FTP/

Internet Browser/Command Communications)

When connecting the instrument to your LAN using a LAN cable of more than

30 m or with a cable laid outdoors, take appropriate countermeasures that

include installing a surge protector for LANs. Such signal wiring is susceptible to

induced lighting, which can cause damage to the instrument.

Always configure the LAN settings before connecting the instrument to the net-

work. When you change the settings while connected to the network, the IP

addresses may not be unique or invalid address data may be transmitted over

the network.

Chapter 15 Connection to a Computer

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 (however, ":" (colon) can-

not be used)

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.

Interface LAN

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 dy-

namic 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.

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 devices in the same

network.

Gateway

IP Address

For network connections:

When your PC (or the communicating device) is on another network than this instru-

ment, 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.
