and the sensor settles down in its position. If required, the adjustment can be
repeated to achieve a better (lower) output offset. With experience, it should

Configuration and control using Scream
Scream is a free software application for Windows and Linux PCs. For more
information and download details, please see www.guralp.com/scream/.
The CMG-5TD may be configured using Scream's graphical interface. Right-
click on the digitiser's icon in the source tree and select “Configure” from the
pop-up menu. Using this dialogue, you may interactively set the digitiser's
system characteristics, control the output of streams at different digitisation
rates and set output baud rates and digitiser buffering parameters.
Alternatively, using terminal emulation software, such as PuTTY, minicom or
Hyper Term, you can access the digitiser's command line and send commands
directly to the built in CMG-DM24 digitiser.
This mode may also be invoked from Scream by right-clicking on the
digitiser's icon and selecting Terminal from the pop-up menu. When using
standard terminal programs, you must initiate command mode by typing
+
. This is done automatically by Scream when a terminal window
is opened to a digitiser. If you use the Scream configuration dialogue, data
collection will continue while you are setting digitiser parameters. If you use
Scream's terminal mode or a terminal emulator, data collection will be
interrupted until you exit terminal mode by typing “GO” or issuing a
RE-BOOT command.
