do not have a DHCP server, you will have to set the IP address yourself.

2.Find out the IP address the DCM is using (if you have not set it yourself).

3.If necessary, configure your own computer's IP address so that it can communicate with the DCM.

See Section 2.4, “Connecting to a local network” for full details.

Once you have connected the DCM to your local network or to the Internet, you can use a wide range of methods to retrieve data from it.

•All DCM units feature an on-board Web server, which allows you to monitor and configure the station from any browser (and download data by HTTP, if enabled.)

•

For maintenance, you can log in to the operating system directly over the secure shell protocol, SSH, and use all the standard Unix/Linux tools.

A GCF server can be set up to transmit data to any application that supports the GCF format (such as Scream!, Antelope, or Earthworm.)

The DCM can act as a CD1.0 or CD1.1 transmitter to a specified client, or to multiple clients as an option.

•Optionally, the DCM can also receive and process AutoDRM messages.

In addition, the DCM can be configured to act as a data client, receiving GCF and CD1.0/1.1 data streams, combining these streams and storing or retransmitting them as appropriate. See Chapter 3, “Usage” for full details.
