The following figure illustrates an example in which the MV and a PC are connected to
the network. When connecting the MV or the PC to a preexisting network, the transfer
rate, connector type, etc. must be matched. For details, consult your system or network
administrator.

Note
•Depending on the reliability of the network or the volume of network traffic, all the transferred
data may not be retrieved by the PC.
•Communication performance deteriorates if multiple PCs access the recorder simultaneously.

2.3 Configuring the Ethernet Interface
Explanation
The following configurations must be made in order to use the Ethernet communication
functions of the MV.
Setting the IP address, subnet mask, default gateway, and DNS
Confirm the settings such as the IP address, subnet mask, default gateway, and DNS
with the administrator of the system or network on which the recorder is to be used.
•IP address
•Set the IP address to assign to the MV. The default setting 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.
•Subnet mask
•Specify the mask that is used to determine the network address from the IP
address. The default setting is “0.0.0.0.”
•Set this value according to the system or the network to which the MV belongs.
In some cases, this setting may not be necessary.
•Default gateway
•Set the IP address of the gateway (router, etc.) used to communicate with other
networks. The default setting is “0.0.0.0.”
•Set this value according to the system or the network to which the MV belongs.
In some cases, this setting may not be necessary.
•DNS (Domain Name System)
You must set the DNS, if you are using a host name to specify the destination
server of the file transfer on an FTP client or the server of the e-mail recipient.
* 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.
•DNS server
•Set the address of the DNS server. The default setting is “0.0.0.0.”
•Up to two DNS servers can be specified (primary and secondary). If the
primary DNS server is down, the secondary server is used to search the host
name/domain name and IP address.
•Host name
Set the MV’s host name using up to 64 alphanumeric characters.
•Domain name
•Set the network domain name to which the MV belongs using up to 64
alphanumeric characters.
•When the destination server of the file transfer or the server of the e-mail
recipient is looked up using the DNS server, this domain name is appended
to the host name as a possible domain name if it is omitted . The destination
name (server name) becomes the “FTP server name”(see section 2.5) or the
“SMTP server name”(see section 2.11).
