CMG-DCM Data Communications Module
You can retrieve data from a DCM's disk at any time by
removing it from the module and attaching it to a PC using a
USB or FireWire cable. Swapping disks does not cause any risk
to data.
•
A stand-alone DCM can also be supplied in a form factor
suitable for mounting in a standard 19” rack. Such a DCM will
normally come equipped with eight additional serial ports
TTS0-7, and an optional State of Health (SOH) interface for
monitoring or tamper evidencing.
Up to four modules may be mounted side-by-side in a 19” rack.
•
An integrated or modular DCM may be combined with a
digitizer and seismometer to produce a single unit capable of
measuring seismic data, storing, and passing it on over a
network:
