Smart Line Interface Module (SLIM)


The Seismic Instruments SLIM unit provides power, control and data gathering functions for two SMG strings. It also provides command, synchronization and telemetry handling between adjacent SLIMs.

Power to the SMG string is provided via a current source. Control consists of synchronization signals and SMG parameter configuration data. 

In addition to powering and controlling the SMG strings, the SLIM buffers SMG data and transmits this data back to the CRU. The SLIM also handles command and synchronization signals from the CRU.

  • Transmits data from SMGs to the CRU
