Greetings! This a GREAT source of information! One of the links in the download section describes how to build a 1 input - 2 output DMX Splitter. This is close to what I am after. I would loke to build a 1 input - 3 output splitter with optically isolated outputs. Does anyone have a schematic for this configuration that is discriptive enough for a "dumb" Mechanical Engineer to follow? I have built pc boards in the past and I think I could pull it off with a good schematic. Thanks in advance!
