Some of these options can also be altered in the Configuration setup
window. For more information on the Control window, see section 3.2
on page 37.
If you need a more powerful interface to the CD24, you can also issue
commands to it directly using Scream!'s terminal mode. A terminal
window is opened by right-clicking on the digitiser's entry in the list
and selecting Terminal.... The digitiser will stop transmitting data
while you have a terminal window open but may still store it in Flash
memory (depending on the current transmission mode.)

configuration options available for the CD24. Many of these options
will also be available for other Güralp digitisers.
