Guralp Systems CMG-DCM build <10,000 - Manual (Page 183)

Acquisition Modules and Platinum Firmware Transmitting Data
The Database directory field can be used to control the location of the
ring-buffer and associated files. In most configurations, the default location is
adequate but if, for example, a very large ring-buffer is desired and the
optional extra flash memory module is fitted, it may be desirable to use the
extra memory for this purpose. To do this, enter into this field the path to a
unique directory under /media/flash_module.
Log file: It may sometimes be desirable, for debugging purposes, to separate
log messages for this transmitter from the standard system log. The text field
can be populated with a path name which will then be used for dedicated
logging. If left blank, logging occurs (via the standard Linux syslog facility) to
/var/log/messages.
Log level: The drop-down menu controls the level of detail present in log
messages, whether to syslog or to a dedicated log file. Not all of the standard
syslog logging levels are available. The menu offers a choice (in order of
decreasing detail) of:
• Debugging information
• Informational messages
• Important notices
• Warnings
GDI multiplexer: In most configurations, all data for all transmitters is taken
from a single multiplexor, as described in section 6.1 on page 65. For more
complex configurations, it is possible to configure multiple multiplexers, each
with their own set of input and output services. In these situations, the
drop-down menu can be used to select a multiplexer instance with which to
associate this transmitter. The menu offers a list of currently configured
multiplexers.
