The RPM out signal is nominally at 0 volts and steps to 12volts for 0.1 milliseconds. The RPM out signal pulses once per engine revolution. The installermust verify compatibility between the RPM out signal and the RPM input requirements of theaircraft's propeller controller. The following diagram details all of the connections that need tobe made between the Rotax 912 iS and the SV-EMS-221, as well as the optional RPM signaloutput to a propeller controller:Figure 28 - SV-EMS-221 / Rotax 912 iS Connections7-26 SkyView System Installation Guide - Revision O
