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 remote station code if different from the inventory station code. Usually leave this parameter unconfigured. If configured and different from the inventory station code, the remote station code will be renamed to match the inventory station code. Defines the remote network code if different from the inventory network code. Usually leave this parameter unconfigured. If configured and different from the inventory network code, the remote network code will be renamed to match the inventory network code. Usually stations with the same source addresses and dialup options are grouped together and managed by a chain plugin process. Here you can define 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. Optionally rename channels. This is a comma separated list of strings where each item defines one mapping from source to destination in the format "LOCCHA:LOCCHA". Either LOC or CHA can contain wildcard characters (question mark) and the location code (LOC) in both identifiers is optional. ??HHZ:10HHZ renames all HHZ location codes to 10, 0J???:??? renames all 0J location codes to nothing (''), HH?:EH? renames all HH channels to EH, etc. Optionally 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 "LOCCHA:ID:1" where 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, LOCCHA refers to the final channel name after renaming.
