    Thanks Shawn
    The E-Mag installation manual says the tach output on connector #6 is two 10v pulses per revolution.
    Connecting a diode (presumably a 5V zener) from the tach output to ground drops the voltage to 5V.

    The AF-2500 RPM would be changed in calibration for four pulses per two revolutions.
    If I connect the E-Mag tach output directly to the RPM input on the AF-2500 with the zener diode to "common" would this be OK?
