Hi,

I've found very good article on Circuit Cellar's September 2004 issue named
"DMX-512 Control - Build a USB-to-DMX-512 Converter".
(Circuit schematics and programs can be found the authors web-site:
http://www.kalbermatter.ch/index3.htm) Also I can supply pdf article on a
demand.

Previously i've been trying to implement picmicro based transmitter for dmx
controller but after showing this article i've decide to implement
usb-to-dmx controller. But i've a problem with this article the author
mentions "galvanic isolation"  for protecting pc against over voltages. How
can integrate such a protection to the existing circuitry?


After reading this magazine article i've searched some on google for
pc-based lighting control softwares and saw very sophisticated one named
eCue programmer (from www.ecue.tv). It has very powerful sound2light feature
that will activated via hardware dongle. I want to implement such a
complicated lighting control interface for my own use. My IDE choice will be
LabWindows/CVI, i've some experience with it, but i need some techinal help
for developing sound to light conversation...

Any help would be very appreciated,

Thanks in advance,
G=F6khan SEVER.
