    ETC Source 4wrd & DMX Loss

    I recently installed some Source 4wrd retrofits. I am really happy with these fixtures and they perform as advertised. Great job ETC! However, one thing that I cringe to think about... When the S4wrd loses DMX, the light goes out. And there's no way to change DMX loss behavior. Just hope...
