    keyword=pin polarity

    All our ADC inputs are negative-going. This is true for BPM and
    raster, as well as PMT signals. Put the "ground" on the left-side
    pin and the "signal" on the right-side. The left-side is labelled
    "+" on the unit, so put the ground on "+". Vince's halog has this
    backwards but he tells me it was a typo.
