It is suggested to read those sections first for familiarization as this section will only highlight the fundamental differences to those common decoders. This decoder is comprised of a single cam-speed wheel in the same configuration as a crank-mounted missing-tooth wheel. The number of teeth ***must*** be evenly divisible into 720°. As it rotates at half crank speed, the sensor reads half the wheel teeth on each 360° crank revolution, and the remaining teeth on the next crank rotation. A single missing tooth will appear on only one of the two crank rotations, and is then used as a phase indicator, much as the dual-wheel system uses the cam signal. @@ -21,10 +21,10 @@ Due to typically limited teeth, only half the teeth being read on each revolutio ![missingtooth_cam_triggerconfig.png](/img/decoders/missingtooth_cam_triggerconfig.png){.align-center width=450} **Fields:** -- Primary base teeth: This is the number of teeth the wheel would have if there were none missing, e.g. a 36-1 wheel has only 35 actual teeth, but you would enter 36 into this field. -- Missing Teeth: The size of the 'gap' in the number of teeth.
