TRIGGER INPUTS

The SMT8_4 derives the RPM reading from the CRANK signal input (pin2/14). The CAM signal inputs can be left open.


All trigger inputs require :

 

  • Connecting to wires (pickup, sensor)
  • Comparing the input signal to some preset trigger level


The SMT8_4 has three trigger inputs and outputs located on the 12 pin connector.
