    222 === Advanced Description === 
    223 ==== !SeedLink data transfer, uni-station and multi-station mode ==== 
    224 The !SeedLink protocol allows two different modes of data transfer.  Uni-station mode is the method used for transmitting a single data stream (station) over a single network connection.  In this case the client does not specify a stream key (network and station code) as the data stream is implied by which address and port the client connects to (similar to LISS Protocol ver.  1).  Multi-station mode is the method used for transmitting multiple data streams (stations) multiplexed together over a single network connection.  Uni-station mode is supported by all current !SeedLink versions.  Multi-station mode is supported by !SeedLink 2.5 or later (SeisComP-1.1.6 or later). 
    225  
    226 For slink2ew the presence of one or more Stream commands in the configuration file triggers multi-station mode.  Otherwise the module defaults to uni-station mode. 
    227  
    228 ==== !SeedLink selectors ==== 
    229 !SeedLink selectors are used to request specific types of data within a given data stream, in effect limiting the default action of sending all data types.  A data packet is sent to the client if it matches any positive selector (without leading "!") and doesn't match any negative selectors (with a leading "!").  The general format of selectors is LLSSS.T, where LL is location, SSS is channel and T is type (one of [DECOTL] for Data, Event, Calibration, Blockette, Timing, and Log records).  "LL", ".T", and "LLSSS." can be omitted, implying anything in that field.  It is also possible to use "?" in place of L and S as a single character wildcard.  Multiple selectors are separated by space(s).

    231 Some examples: 
    232 {{{ 
    233 BH?          - BHZ, BHN, BHE (all record types) 
    234 00BH?.D      - BHZ, BHN, BHE with location code '00' (data records) 
    235 BH? !E       - BHZ, BHN, BHE (excluding detection records) 
    236 BH? E        - BHZ, BHN, BHE & detection records of all channels 
    237 !LCQ !LEP    - exclude LCQ and LEP channels 
    238 !L !T        - exclude log and timing records 
    239 }}} 
    240 For slink2ew only data records will be written to the ring.  In other words, requesting any records in addition to data records is a waste and you should always append ".D" to any specified selectors.
