Im not sure what to call this but I have quite a problem and need some help as soon as possible! I am running a show off of the Chamsys Magic Q Pc with the Enttec Open DMX/USB. I am controling 4 scrollers and 21 old EDI dimmers that I believe were originally anologe and are now converted to DMX. Everything worked perfectly until I needed to plug in my laptop to the wall. The minute this happened all my scrollers began to go crazy and jitter back and forth in the middle of a color. I take out the cord and everything goes back to normal. I am using old Chroma Q Scrollers and the lines are terminated back to the PSU. However there is no termination on the DMX itself as the wall box only has an input jack.
