Abstract

A borehole system having a string, the string including a converter module fluidically connectable to a downhole tool, the converter module including a piston in fluidic communication with the downhole tool, wherein the converter module is configured to provide a source of converter module pressure to the downhole tool. A method of connecting the downhole tool to a source of balance pressure includes fluidically connecting a balance line chamber of the converter module to a balance line of the downhole tool, the converter module having a piston, the piston fluidically engageable with the balance line chamber, wherein the piston is movable in response to changes in balance line fluid pressure within the balance line chamber.
