Minicom Advanced Systems CMG-DCM manual Cmg-Dcm

CMG-DCM

disk.recordas.seed : Set this to yes to have the DCM record full SEED volumes on the hard disk. This option will have no effect until you create a datatransfer.seed.config file. See “SEED” in Section 4.5 for information on these options.

disk.recordas.sac : Set this to yes to have the DCM record files in sac format.

The next set of options allows you to select the data sources for archival.

disk.recordfrom.serial.n : Each of these options refers to a serial port on the DCM by its number. Select yes to have the DCM record data coming into this port.

disk.recordfrom.scream : Select yes to have the DCM record data it receives from remote Scream! servers (either computers running Scream!, or further DCMs and AMs.) If you want to use this option, you should also configure the datatransfer.scream.client options (see below.)

disk.recordfrom.http : Select yes to have the DCM record data it receives using the HTTP protocol. If you want to use this option, you should also configure the datatransfer.http.client options (see below.)

disk.recordfrom.cd1_0 : Select yes to have the DCM record data it receives using the CD1.0 protocol. If you want to use this option, you should also configure the datatransfer.cd1_0 options (see below.)

disk.recordfrom.cd1_1 : Select yes to have the DCM record data it receives using the CD1.1 protocol. If you want to use this option, you should also configure the datatransfer.cd1_1 options (see below.)

disk.power : To save power, the on-board hard disk can be set to power up only when required. If power consumption is an issue and you expect the hard disk to be used only occasionally, you should set this option to automatic. Otherwise, setting it to always-onwill ensure that the hard disk is always ready to receive data. If you intend to operate an internal disk continuously, you should take care not to let it overheat, since the interior of the DCM is well insulated.

disk.usagemode : This setting varies the way the DCM uses its hard disk storage once it has been filled up.

•The use-onceoption causes the DCM to stop recording data to the hard disk, and discard any new data that arrives. It may still send new data over the network, if you have so configured it, but the hard disk will be untouched once full. Thus the start point of the stored data is known, but the end point depends on the disk capacity. This is most useful for installations where you are expecting to replace the hard disk periodically, or where you need to take time-synchronized readings at several sites.
