Abstract: A seismic data acquisition system includes a connector housing (300) and a mating electrical circuitry module (200). A single interface couples electrical circuitry (140) housed in he electrical circuitry module (200) to one or more signal data carriers (43) that are consolidated at a single location in the connector housing (300). Preferably, the connector housing (300). Preferably, the connector housing (300) and electrical circuitry module (200) each have a substantially contaminant-free interior regardless of whether these two parts are mated. An alternate connector housing has two plug casings, each of which are provided with a plug. A complementary alternate electrical circuitry module includes two receptacles complementary alternate electrical circuitry module includes two receptacles complementary to the plugs and an interior space for holding the electrical circuitry. A locking pin disposed within the plug casing selectively engages the electrical circuitry module (200). A method for establishing communication between the electrical circuitry (14) and the carriers (43) and external devices includes providing a single communication interface between the carrier and the electrical circuitry.
