Guralp Systems CMG-DCM - Manual (Page 73)

Operator's guide
default: to make the DM24 output a CD stream, connect to its console
and issue the command
+MONITOR
This can be done from the DCM command line (see Section 8.2, page
117) with the command
gcli n '+monitor'
where n is the number of the serial port attached to the digitizer.
CD1.1 subframe configuration
CD1.1 data is organised into subframes, which have some flexibility in
their format. A configuration file, /etc/cd11sf.cfg, is provided
allowing you to specify the exact format to be used in outgoing CD1.1
subframes. Clicking CD1.1 subframe configuration brings up a page in
the work area which enables you to edit the file and its attributes
directly.
The Web interface does not check that the content of the files will be
understood. You should ensure that the file is valid before committing
any changes.
Each line in /etc/cd11sf.cfg describes a single CD1.1 stream in the
format
data-stream:status-stream:location:site:instrument:channel:prefix:
key-bucket
where the fields, separated by colons, are:
data-stream : the digitizer's data stream ID;
status-stream : the digitizer's status stream ID;
location : the CD1.1 location code for the array;
site : the CD1.1 site code for the instrument;
channel : the CD1.1 channel name;
prefix : a prefix for the location to store the files in the file tree of the
DCM.
key-bucket : the key-bucket code, which tells the DCM which key to
use for that particular stream.
