seedlink Global options for the chain plugin Defines the maximum number of concurrent dial-up connections. A value of 0 does not limit the concurrent connections. If enabled load_timetable is used by the chain plugin to request the available time windows of each stream in the Seedlink buffer to discard older records. Seedlink server (TCP/IP) Hostname or IP of the Seedlink server. Port of the Seedlink server List of stream selectors. If left empty all available streams will be requested. See slinktool manpage for more information. Defines the input station if different from the stations code. Usually leave this parameter unconfigured. If configured and different from the stations code the station code will be renamed to match the local station code. Defines the input network if different from the stations network. Usually leave this parameter unconfigured. If configured and different from the stations network code the network code will be renamed to match the local network code. Usually stations with the same source addresses and dialup options are grouped together and managed by a chain plugin process. You can give here an additional group ID. Available placeholders are $NET and $STA that are replaced by the network code or station code. Whitespaces are replaced by underscores when generating chain.xml. The default timing quality is used when unpacking data that does not contain blockette 1001, that allows SeedLink to construct blockette 1001 for downsampled data. If overlap removal is set to "initial" or "full", then earlier records will be discarded (record number is used in case several subsequent records have the same header time). All other values are treated as "none". Leave this option unset unless you know what you are doing. If enabled then the chain plugin tries to subscribe for channels with the BATCH command which is magnitudes faster than the old handshake. Not all SeedLink servers support the BATCH mode so it needs to be turned off in case of problems. Enables dialup mode. Needs schedule and uptime to be set accordingly. Dialup uptime in seconds. The dialup schedula in cron format. An optional dialup ifup script. An optional dialup ifdown script. Allows to rename channels. This is a list of strings where each item defines one mapping in the format "SRC_LOCCHA:DST_LOCCHA". Either SRC_LOCCHA or DST_LOCCHA may contain wildcard characters (question mark) and the location code (LOC) in both identifiers is optional. Allows to unpack channels instead of sending them as miniseed to Seedlink. Unpacked streams can be downsampled by Seedlink. This is a list of strings where each item defines one unpack mapping in the format "SRC_LOCCHA:DST_ID:1" where DST_ID can be an arbitrary channel id which must match the definition of a stream in streams.xml. The last ":1" is optional and defines if the unpacked data should be doubled (duplicate each sample). In case rename mappings are active, SRC_LOCCHA referes to the final channel name after renaming.
