CMG-DM24S12AMS Operator's guide
In addition to the main 24-bit analogue inputs, the digitiser module
features an additional 16 slow rate 16-bit resolution analogue inputs.
The inputs to the slow rate channels are through the connector marked
AUXILIARY INPUTS. These inputs are all single-ended and use a fixed
sample rate of 4 samples/s.
The DIGITAL A − F connectors are provided for use with Güralp
Systems digital output seismometers (such as the CMG-3TD) or
accelerometers (CMG-5TD). Like the analogue inputs, the DIGITAL A −
F connectors can supply power to the digital sensors. Alternatively, if
required, the DIGITAL A − F can be used as serial interfaces (e.g. to
remote installations connected by modem.)
The DM24S12AMS unit can be powered either from 110 – 250V AC
mains power, or from a 12 V DC power source. In addition, a
BATTERY/UPS connector is provided, for attaching to a rechargeable
battery or UPS. If power is provided through one of the other sockets,
the battery will be recharged at 14 V. There is also an external USB port,
and a standard parallel port within the casing.
