1. A surface control system for controlling an initiator in a downhole perforating gun string comprising:
a perforating unit further comprising a software driven power supply, a control board coupled to the power supply, wherein the power supply is programmed to automatically output a specified amount of voltage/current, without user action, over a specified period within a specified depth window;
wherein the perforating unit deactivates the software driven power supply after an initiation is detected;
wherein the perforating unit automatically determines that the perforating gun string is approaching the shot depth and then commands the firing of at least one perforating gun using the software driven power supply based on acquired data including the depth, at least one active addressable switch in the toolstring, distance between predetermine shot locations, time to increase voltage for firing, and time required to communicate with each of the at least one addressable switch after firing the perforating gun string determines that the shot was fired; and
a winch controller receiving depth data, wireline surface tension data, and a winch control feedback wherein the winch controller evaluates the perforating gun string ascent speed and then sends commands to the winch motor to achieve a calculated optimal winch speed required to perforate on programmed depth while retrieving the toolstring from bottom based on shot distances and required firing time, depth data from a winch, line speed data from the winch, and surface tension data from the winch; and
wherein the perforating unit communicates with at the least one addressable switch.
