Matrox Iris GT auxiliary output 4 (AUX(USER)_IND_OUT4) is a pulse-width
modulated signal (PMW) that can turn the strobe lamp on, off, and adjusts the
intensity of the strobe lamp. The signal produces a series of pulses that have a duty
cycle proportional to the intensity setting in your Matrox Design Assistant project.
