At this point, I'm only comfortable describing the circuits since they belong to my employer. It's really just a 16c74a with the previously described resistor between INT and 12VAC, an interface chip between the DMX lines and the serial input, a thumbwheel channel select connected to some port lines, 0-10volt analog inputs (thru voltage dividers) to analog inputs, and a few more port lines driving opto-triacs. The rest is software! Harold _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.
