CMG-DM24S12AMS Operator's guide

Here, the twelve CMG-5U uniaxial sensors can be distributed

throughout a building to capture its response to ground motion, while a

digital CMG-5TD unit is embedded in the ground nearby to capture the
ground motion itself. Data from all thirteen instruments is fed into the

DM24S12AMS, where it can be stored and processed on-site or

alternatively sent across a local network or the Internet. If required, up

to five further digital instruments can be connected to the

DM24S12AMS (not shown).

The DM24S12AMS unit’s 12 analogue input connections are each

identical to the output connection of the Güralp CMG-5U. These

connections also serve as the sensors’ 12V power supply. If required,

other types of sensor may also be wired to a DM24S12AMS module.

Using compatible connections, you can control all the sensors through

the module, either using its integrated PC or from a remote location on

your network. The digitiser can also provide common calibration and
GPS timing signals to all the sensors.

All DM24 digitiser units are fitted with high-impedance, low-noise,

differential input pre-amplifier modules.
