In most configurations, all data for all compressors are taken from a
single multiplexor, as described in section 1.3 on page 10. 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 GDI multiplexer drop-down menu can be used to
select a multiplexer instance with which to associate this compressor.
The menu offers a list of currently configured multiplexers.
11.3.2 The SEEDlink server
The SEEDlink server transmits data in miniSEED format (data only, no
station and channel metadata) over the network to remote data
consumers. The data are generated by a GDI Mini-SEED compressor
instance.
A single SEEDlink server instance takes data from a single compressor
instance and can serve multiple, simultaneous clients. If it is required
to serve different channels to different clients, multiple server
instances should be configured, each receiving data from a different
compressor instance (the channel selection is controlled by the
compressor, not the server). A server has a configured “Organization”
name: if data are to appear to come from multiple organizations,
multiple server instances should be configured: they can share a
compressor instance if they will be serving the same channels or a
number of compressor instances can be used.
To configure a SEEDlink server from the web interface, select “System
services” from the “Configuration” → “All options” menu or select the
“Services” short-cut from the “Data transfer/recording” menu. To
configure a SEEDlink server from the command line, start gconfig
and select “System services” from the top level menu.
Now select “seedlink-out -- SEEDlink network server” from the System
Services menu. The next screen shows a list of all SEEDlink server
instances that have been configured:
142 Issue C
Note: The SEEDlink server requires data in 512 byte blocks -
the compressor must be reconfigured from its default setting
(4 Kbytes) if the SEEDlink server is to be used: see the previous
section for details.
