Abstract
An electronic control system for a downhole tool controls an operational state of the downhole tool. The electronic control system receives a signal from uphole, and drives a motor to operate a valve, alternately fluidly connecting a chamber in the valve to drilling fluid in a bore of the downhole tool, causing an activation mechanism to configure the downhole tool into a first state, and fluidly connecting the chamber to an annulus surrounding the downhole tool, venting mud into the annulus.
