The light named its own personality via dmxtest's cycling labeled
patterns (3ch-white / 7ch@1-red / 7ch@3-red): Chauvet Wedge Tri, 7ch
at address 3. notepat's dmxMap pins macro/strobe/auto to 0 and rides
the dimmer at full so color does the fading. dmxtest stays as the
fixture interrogation tool, and drops /pieces/dmxdiag.txt for remote
readback over lanserv GET.
