Abstract
An initiator circuit for a perforating gun includes a microprocessor structured to perform a circuit-startup algorithm comprising determining whether the circuit supply voltage is stable enough for operation and, if it is, or if a predetermined period of time has passed since powering up the circuit, sending a message indicating the circuit (and thus gun) is ready for operation. The sent message may be a communication uplink indicating an address of the circuit and its ready state or a short burst of pulses indicating the circuit's ready state.
