CMG-EAM (Platinum Firmware)
1 Introduction
The CMG-EAM (Embedded Acquisition Module) is a versatile module
intended to integrate one or more seismic sensors with various
communications systems. It can also act as a stand-alone data recorder
or as a communications hub in larger networks.
This document describes the configuration and
operation of Platinum Firmware, which is the native
firmware of CMG-EAMs, CMG-NAMs and CMG-DAS
units. CMG-DCMs can be upgraded to run Platinum
firmware: for such units, once upgraded, this manual
should be used instead of MAN-DCM-0001.
The CMG-DCM is a stand-alone
communications module equipped
with a removable hard drive
(located under the lid), three bi-
directional serial ports and
support for external USB storage
devices and Ethernet networking.
Some CMG-DCMs were embedded
into CMG-DAS units such as the
DM24S3DCM (see below).
The CMG-EAM is the next
generation CMG-DCM and
includes totally re-designed
electronics. It provides all the
above facilities along with an extra
serial port (designated for console
use), a battery-backed real-time
clock, current, voltage and tamper-
line monitoring plus an optional
encryption/authentication module.
The CMG-EAM is available in a
variety of packages including Peli-
case (as shown above), borehole,
ocean-bottom and metal tube (steel
or aluminium) versions (top left).
CMG-EAMs are also supplied
embedded into CMG-DAS units
such as the DM24S6EAM.
