    Spindle sync signal levels

    New CNC USB controller Mk3/4 what signal levels are require for spindle encoder and index signal, ENC A, ENC B and IDX,
    I presume 5v.
    Does it require a negative going pulse or positive
    What wave form does it require

    I have been through the Planet CNC Blog and seen how to wire, been through the posts here but have found nothing,
    please point me in the right direction if i have missed it.
    Many thanks
