CMG-DM24S3DCM
The CMG-DM24S3DCM combines a low noise DM24 digitizer and EAM data module in a single case. Connected to any Güralp Systems sensor or to your own hardware, the DM24S3DCM can record high-quality data in a range of formats on a hot-swappable, high capacity USB hard disk.
Using its flexible Linux-based operating system, the DM24S3DCM can also act as a network data centre for permanent installations. A 6-channel variant, the DM24S6DCM, is also available.
Features
- Under 2 W total power consumption
- 4 low noise 24-bit channels (3 primary and 1 auxiliary)
- STA/LTA, level, and external trigger
- 4 concurrent output sample rates (continuous or triggered) on each channel
- Auxiliary channel for user signals and calibration
- Multi-user Linux operating system with full network support
- Remote configuration with Scream! or the on-board Web server
- On-board USB hard disk with temperature control (40 Gb +)
- Protected FAT-based file system ensures complete data surety
- Full remote control of digitizer parameters
- Remote sensor mass locking, unlocking and centring
- Real-time conversion to multiple data formats including GCF, full SEED, miniSEED and SAC
- Network protocols including Scream!, SeedLink and CD1.0/1.1
Recording options
The on-board hard disk.
With unrivalled data processing capabilities for a low-power device, the DM24S3DCM is an ideal choice for autonomous stations.
The high-capacity on-board hard disk is capable of recording data from experiments of several months' duration depending on the configured sample rates. Direct recording to MiniSEED, and GCF format is supported out of the box.
The purpose-designed hard disk supplied with the unit includes a built-in heater, allowing recording even in conditions too cold for a conventional PC.
A Windows-compatible journalling file system allows the disk to be replaced while the station is running, with no loss of data.
Web page interface
Direct configuration and data monitoring.
A flexible and innovative feature of the CMG-DM24S3DCM is its on-board Web server, which can be configured and accessed securely from a local network.
Using the Web server, authorized users can monitor data, alter output channels and sample rates, and perform station maintenance.
Data from the hard disk can also be downloaded remotely, allowing operators to check the state of health of an autonomous station.
