Click Save changes to save the configuration and start writing SEED volumes. One volume will be written for each stream every three hours. The DCM will always start a new volume if it is power cycled; the aborted file will still be a valid SEED volume.
Real-time data transmission
You can use the DATA OUT port (or any of the DCM's serial ports) in several ways, depending on the service you have chosen to run on the port.

By default, the DATA OUT port runs the getty service, which allows you to connect to the DCM's console.
The mgetty and mgetty_raw services are similar, but can deal with connections made through modems.
The gcf_out service causes the DCM to combine the incoming GCF streams and send them on transparently, as for a Gü ralp SAM or CRM.
The gcf_in service turns the port into an extra digital data input port. The DCM's PORT A and PORT B run the gcf_in service.
Scream! server
In a straightforward vault installation, we recommend that you leave the DATA OUT port running the getty service for emergency console access, and instruct the DCM to act as a server for incoming data on your network. This can be done from the Data transfer → Scream! → Server page on the Web site:
1. Enable the Scream! server on the DCM by setting
datatransfer.scream.servertoonand datatransfer.scream.server.allowserialaccess to yes. Make a note of the port number datatransfer.scream.server.port, or change it to another. Click Save settings.
2.Start up Scream!, and select Windows → Network Control... from the main menu. Click the My Client tab.
3.If it is not already selected, check Receive Data to start Scream! listening.
