It would seem that both I and many members have many many issues with various blanking and modulation problems. I am starting this thread to hopefully bear bleeding hearts in this area , and am hoping that our more enlightened members will spill some of their knowledge ideas and solutions in resolutions to these problems. My personal issue is how is blanking and modulation dealt with via software and or hardware when using a RGB scanner setup with the associated showlasers DMX board that produces RBG 5 volt TTL blanking signals. My initial is using modulation with a lone 532 laser and when blanking is connected I lose preprogrammed image elements intended for other colors. Very soon it will be issue of using RGB modulation to use as a RGY projector. I presume that better quality or possibly most showlaser software & ILDA interface solutions very simply deals with these issues.
