Networking Your DVM4
The Ethernet connection is a useful tool for transferring video and other files to
and from the unit. It is also useful for transferring feature updates and
controlling and monitoring the DVM4. Ethernet is a physical medium for
transferring data. TCP/IP is used to transmit the data over the Ethernet. TCP/IP
is a common “protocol” for transmitting data on local Ethernet connections
(
Intranet ) and also global connections ( Internet ). The DVM4 allows both. We
will refer to the use of either an Intranet or the Internet as the Network .
Connecting to the DVM4 via Ethernet
The DVM4 is shipped with a factory default IP address of 192.168.0.254, which
is useful for transferring video across an Ethernet LAN, but must be changed if
the Digital Video Machine 4 is to be connected to a router on the Internet. This
IP address represents the official test IP address.
The DVM4 is configured with default TCP/IP settings. These setting are the IP
address, the login name, and the login password. These settings need to be
changed only if the unit is to be used on an Intranet or the Internet. If you intend
to use Ethernet only to transfer video files into the unit, then the default settings
will work just fine.
If you are connecting the DVM4 to an existing Ethernet LAN Intranet, then the
Network System Administrator will need to provide you with a unique IP
address for the DVM4. If you are connecting the DVM4 to the Internet, then
your Internet Service Provider (ISP) will provide you with a unique IP address.
The default login name is admin , and the default login password is password .
The password should be changed if the DVM4 is going to remain on the
Network.
To change any of these three settings, you need to connect to the DVM4 serially
or via Ethernet. You can then use the commands in the Protocol list to change
what you need.
The DVM4 comes with a red “Null-Ethernet” (also known as a “cross-connect”)
cable. This cable allows two peers (such as a PC and a DVM4) to communicate
directly without going through a network hub.
DO NOT USE THIS CABLE
TO CONNECT THE DVM4 OR A PC TO A NETWORK HUB.
