CMG-DCM

Other command line tools are available for manipulating the files on the DCM's hard disk. See the manual for full details.

Using miniSEED format

You can instruct the DCM to record data to Flash (and, later, its hard disk) in miniSEED format with the command

gcfgdbset disk.recordas.miniseed yes

or by selecting yes for the disk.recordas.miniseed option using the Disk page of the Web site:

The DCM allows you to record in several formats simultaneously, if you wish; you should make sure that you have the capacity to store, or the bandwidth to transfer, all the data the DCM will produce in each format you have enabled.

Compiling SEED volumes

The DCM can also compile full SEED volumes in real time. To enable this, use the command

gcfgdbset disk.recordas.seed yes

or select yes for the disk.recordas.seed option on the Disk page of the Web site.

Before the DCM can start writing SEED volumes, however, it needs to know technical details for each stream you wish to record. To set these, navigate to

the Data Transfer → SEED page of the Web site and edit the /etc/seed.cfg file. The DCM will only write SEED volumes for streams mentioned in this file. See “SEED” in Section 4.5 for more details.
