Guralp Systems CMG-DCM build <10,000 - Manual (Page 134)

Acquisition Modules and Platinum Firmware Receiving Data
Debug port: It is possible to copy all incoming data, verbatim, to a network
port, which can be specified in the text field. This is an advanced debugging
technique beyond the scope of this manual.
Port name override: Allows the operator to specify a descriptive name for
this data source. If left blank, it will be labelled with the IP address and
service number of the source device, and this label will appear in, for
example, the GDI channels display and the network tree in Scream.
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.
10.3 Data from Scream servers
The acquisition module has the ability to receive data over the network from
Scream servers. Data can be received from a number of Scream servers using
a single Scream client.
To set up a Scream client on the acquisition module, select
Configuration → Services → GCF
or
Configuration → All options → System services → GCF
To configure a Scream client from the command line, start gconfig and
select “System services” from the top level menu.
Select “gcf-in-scream -- GCF Scream network client”. The screen shows a list
of all Scream network client instances that have been configured.
To configure a Scream receiver, select “Create new service instance”.
