Abstract

Effects of capacitive resistances on the transmission of data between electronic igniters of an ignition system and a device for programming and triggering igniters are avoided by the disclosed method. Prior to a planned communication of an igniter with the device, a dc voltage is applied to the ignition circuit for a predetermined length of time. This voltage is higher than the voltage provided for generating the signals with which the data are generated. Subsequently, the signals that the igniter transmits in response are produced with a lower voltage than the previously elevated voltage and the dc voltage is increased once again prior to the response to an additional igniter.
