Guralp Systems CMG-DCM build <10,000 - Manual (Page 131)

Acquisition Modules and Platinum Firmware Receiving Data
Audit log size: The GCF input subsystem keeps its own audit log,
independent from the system log. The contents of this log are available using
the “GCF Audit Log viewer” facility as described in section 14.4.5 on page
241. The amount of data retained is controlled by the drop-down menu
where the choices are:
• 64Kib (small)
• 256Kib (medium)
• 2MiB (large)
• 16MiB (huge)
Debug port: It is possible to copy all incoming data, verbatim, to a network
port, which can be specified in this field. This is an advanced debugging
technique which is beyond the scope of this manual.
GDI multiplexer: In most configurations, all data from all inputs is sent to a
single multiplexor which then feeds all outputs, as described in section 6 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 receiver. The menu offers a list of currently
configured multiplexers.
10.2 BRP - GCF From Network Devices
The acquisition module can receive data from network enabled instruments
such as the CMG-6TD and networked digitisers such as the CMG-DM24. Data
can be received from any number of sources, by creating multiple GCF BRP
receiver instances.
To set up a GCF BRP receiver on the acquisition module, select
Configuration → Services → GCF
or
Configuration → All options → System services → GCF
To configure a receiver from the command line, start gconfig and select
“System services” from the top level menu.
Select “gcf-in-brp GCF BRP network client”. The screen shows a list of all
GCF BRP receiver instances that have been configured
To configure a new GCF BRP receiver instance, select “Create new service
instance”. The screen allows you to configure the parameters of the service
