METHOD OF PROVIDING A SERIES OF FLYER GROUPS MADE UP OF A FLEXIBLE TOTAL NUMBER OF GEOPHONE FLYERS PER GROUP CONNECTED TO A REMOTE DIGITAL ACQUISITION AND TELEMETERING CIRCUIT UNIT (RDATC) OF A FIELD SEISMIC DATA ACQUISITION SYSTEM AND TO EACH OTHER IN A MANNER WHICH MINIMIZES HELPER MIX UP ABSTRACT OF THE DISCLOSURE The method and apparatus of the present invention are described in which connection (and disconnection) of a plurality of geophones associated with a series of stations of a digital seismic data acquisition system is greatly simplified without sacrificing flexibility as to the number of geophone flyers per station or the interval spacing per station and also without the addition of separate subcabling in the internal linkage of the flyer to the field digitizing equipment. The method utilizes a multiple-phone flyer-jumper connected to one channel of a series of channels of a remote data acquisition and telemetering circuit (RDATC). Each RDATC acts in combination with a group of geophone flyers, say 1, 2, 3, etc., to store, amplify, filter, gain control and digitize analog data from each group of flyers and then telemeter the data to recording circuitry in the field truck. Each flyer group can be flexibly made up of two, three, four or more flyer-jumpers; each flyer-jumper includes a central multi-conductor cable segment of say N+1 conductors, where N is an even positive number greater than two, terminating at each of - 1 - its ends in the central leg of multi-armed connector. A plurality of series/parallel connected geophones, say 9 in number are used in combination with the central segment. At the end of the arms of each multi-armed connector pass another conductor cable segment (similar to the central segment, but called the "branch cable segment") in which only two of the cables are actively connected o the selected conductor pairs of the central segment. At the other end of each branch cable is a hermaphroditic connector including a 2 male-2 female combination, with connection occurring between 1 male-l female subunit by paralleling them electrically. In that way either (i) the three geophone conductors of the central cable segment can be flexibly connected to 1, 2, 3, etc., or more similarly located connectors of other flyer-jumpers to increase signal response of the resulting flyer group or (ii) the remaining conductor pair can be connected to outside circuits including the RDATC to actively transfer data from more remotely located geophones of adjacent flyers of interest. Repairs to flyer-jumper in the field is relatively simple. Of interest: each hermaphroditic connector is color coded to facilitate geophone flyer-jumper field setup and connection in a variety of arrangements with a minimum of helper mix up.
