Abstract
System for the input and output of data on a two wire system with a downhole well tool which has a system with sensor devices, a processor, a clock, a memory and a voltage/current communications device which are all powered by a d.c. battery. A phone jack and phone plug connection at the earth's surface enables an operator with a controller to input and output data to the well tool without disassembly and enables setting the clock in the well tool to a selected real time value. This enables synchronization of real time values of data recordings for different tools.
